The Best Bathroom Scale

A bathroom scale is an essential in nearly every household. That’s why we spent over 27 hours researching both standard and smart bathroom scales as well as conducting over 250 weighs-ins. After significant research, we narrowed down to the top nine scales and determined that the Weight Gurus Smart Scale – 0375 was the best overall due to its wide-ranging abilities, accuracy and reliability.

Some other standard scales proved to be incredibly consistent, like the EatSmart – ESBS-01 and Vive – DMD1002SLV. Surprisingly, we only had one scale achieve perfection in both accuracy and consistency. This beautiful piece of craftsmanship is the Etekcity – EB4074C (no wonder it’s the number one Best Seller on Amazon).

Top Pick: Weight Gurus Smart Scale - 0375

After many weigh ins, the Weight Gurus Smart Scale was off by only five pounds out of almost 3,000 total pounds. It also provides you with a consistent body fat percentage that is tracked automatically with their phone application that is compatible with other apps like FitBit, Apple Health and Google Fit.

How we selected products to test

We scoured through review sites like ConsumerReports.org and TheSweetHome.com to get an idea of some of the best products out there. We then dove into forums on Reddit and read through customer reviews on Amazon. With about ten hours under our belt, we felt confident that we’d developed a solid base of what to look for and how to narrow down our search.

We looked at both the singular function digital scales (non-smart scales) and the multi-functional smart scales, which provide information on body fat, muscle mass and more. In our search of the most accurate and consistent scale, we compared the best ones on the market to one another, using others’ reviews and our knowledge base, ultimately ending up with nine top bathroom scales, three of which are smart scales.

Important features to look for

scales feature comparison chart

Large backlight display: Regardless of how consistent or accurate a scale is, it’s useless if you can’t read the numbers on the display. Thankfully, all of the scales we tested had great displays with easy to see numbers.
iDOO Screen Close-up

Design: While design shouldn’t be the primary determinant you use when buying a scale, you’re more likely to use it if it looks and feels good. You should consider attributes like the feet of the scale, dimensions and weight.

Weight tracking (smart scales only): This feature is incredible to have as it takes away all the tedious work that would otherwise be required to see the changes in your weight over time. This way you can easily see trends with the graphs and all the other visuals the phone applications provide for you. The Weight Gurus Smart Scale – 0375 can even integrate with programs like FitBit and Google Fit.

Batteries: Most of us are familiar with alkaline AAA batteries, but some scales use the lithium CR2032 batteries-, which are flat and disc-like. Here are some graphs from Energizer that display the performance difference. AAA batteries seem to work better and more safely in the long run.

Standard scales vs. smart scales

Smart Scale and Standard Scale
Standard Scale: Your everyday (old-school) non-smart bathroom scale can measure only one thing a: weight. If you want to get technical, then check out the difference between mass and weight. Usually you can switch between measuring your weight in pounds, kilograms or stones.

You may be wondering why we didn’t choose to include any spring-loaded mechanical scales. The answer is simple: mechanical scales that perform well cost about as much as a smart scale but only give you the function of a standard scale.

Smart Scale: Smart scales measure weight, but come loaded with an abundance of other features too. These measurements can include body fat, BMI, muscle percentage, water percentage, bone mass, BMR and protein percentage.

Tips on how to best weigh yourself

The most important thing to keep in mind when weighing yourself is the consistency in your method. From this consistency you will get accuracy. In other words, to ensure you get the most accurate result you need to be consistent in how you weigh yourself.

How to be consistent in your weigh-ins:

  • If weighing every day, the morning is best (at the same same time of day)
  • If weighing once a week, some claim it’s best to weigh yourself on Wednesdays (morning is still best)
  • Weigh yourself before exercising or eating
  • Remove all clothing and jewelry
  • Use the same scale
  • Place the scale on the same hard surface

How we tested

Consistency & accuracy of weight

scale accuracy test data

We did a lot of weighing (over 250 times in total). We weighed humans and weights. Both consistency and accuracy were taken into account with each weigh-in. Before we get started, however, let’s briefly differentiate between ‘consistency’ and ‘accuracy’. A scale will be dubbed as consistent if it produces the same result again and again. An accurate scale is one whose measurement is very close to the actual weight.

To get a feel for the scales, we weighed a subject who wasn’t holding anything. Then we weighed them holding dumbbell A (25.8 lb), holding dumbbell B (24.2 lb) and both dumbbells A and B together (49.6 lb). And yes, the dumbbells are from the same manufacturer and are both supposed to be 25 lb. Evidently they weren’t, so we used professionally weighted dumbbells.

calibrated dumbbells

We went to our (newly-made) friends over at ICC Instrument Company to use the weights they use to calibrate industrial scales. The weights were 50.0 lb each, which made it at least a bit easier to spread out the weigh-ins into groups of 100.0 lb, 150.0 lb and 200.0 lb . We made sure the ground was perfectly level all around and then weighed each of these chosen weights three times. When we did this, we found one scale to be perfectly accurate: the Etekcity – EB4074C).

Then, to test consistency even further we weighed one subject ten times on each of the scales. We used the Etekcity as our baseline for comparing the accuracy of the other scales as it was deemed perfectly accurate and consistent from the previous test. After gathering the data we gave the appropriate rankings to each scale for the below categories, then we averaged the scores and combined them to get an overall ranking of consistency and accuracy.

  • Accuracy of body weight
  • Consistency of body weight
  • Accuracy of standard weight (100.0 to 200.0 lb)
  • Consistency of standard weight (100.0 to 200.0 lb)

Consistency & accuracy of body fat measuring

A quick note on body fat before we look at how we tested it: body fat percentage (BFP) is the total mass of fat divided by the total body mass. The way the smart scales measure this is with Bioelectrical Impedance Analysis (BIA). If you don’t care to read Wikipedia’s explanation of how it works, the smart scale shoots an electric current through your body and uses the resistance between the conductors to create a measurement.

In order to test the BIA we first needed a standard measurement of body fat percentage. There are a couple of accurate ways to measure body fat like skinfold caliper measuring (instrumental body fat pinching) or hydrostatic weighing (underwater weighing). We chose to go with the skinfold caliper testing because it has the best ratio of accuracy to repeatability, so this was our measurement standard to which we compared the results of the BIA.

We took two subjects of similar weight, but with noticeably different fat content and had them undergo three trials of skinfold caliper testing and three BIA evaluations with each smart scale. We conducted these tests within seconds of one another to avoid discrepancies in the amount of body fat throughout the day. With the data collected we were able to determine the percentage of accuracy and consistency between the scales.

body fat ratings

Ease of use

Standard and smart scales

Because there is not too much to non-smart scales, their ratings were based on only a few things. Nowadays none of the top scales require you to tap before they turn on. All of the scales we tested had the “step-on” technology, which means you can just step on and the scale will weigh you without having to turn it on beforehand.

Another area we evaluated was the clarity of the screen. There was not too much difference between the scales here because they are all backlit and have reasonably similar screen sizes. Nonetheless, we measured out the dimensions of the screen and scale and compared the total surface areas–the iDOO Jumbo – ES09-3089M was the only real big difference with about a 30% bigger surface area.

The other areas we looked at here were batteries, grip-to-floor bottom (or non-slip) and transportation. We ranked them each on how easy it was to change the batteries and what type they used. We also thought about anyone who likes to keep their scales hidden away when not in use and rated the process of moving each scale from one area to another.

Smart scales only

We broke the smart scales down into two categories for ease of use. First, we considered how easy it was to track your weigh-ins, the two smart scales that had a phone application were easier (Weight Gurus Smart Scale – 0375 and Yunmai Premium Smart Scale). Secondly, if applicable, we compared the overall user-friendliness of the phone application by adding new users to the account, tracking weights, accessing and reading graphs, and connecting to existing applications like Apple Health and FitBit.

And we evaluated the reliability of the body fat measurement (because after reading all the other reviews and comments this was the most desired datum from smart scale users). This was determined by the accuracy and precision of the measurements.

Best smart bathroom scale – Weight Gurus

Weight Gurus

The best bathroom scale will provide multiple pieces of data, the ability to connect with other applications, and impeccable accuracy and consistency. It really came down to the Yunmai Premium Smart Scale and the Weight Gurus Smart Scale – 0375. They both had exceptional applications that made it easy to track your progress and were both incredibly consistent in their weight measurements. However after looking at the accuracy of the weight and fat-percentage readings, the Weight Gurus Scale stole the show.

Best smart scale

Weight Gurus Smart Scale - 0375

With the Weight Gurus Smart Scale you don’t need a smartphone to view your results, it will automatically save your results and syncs automatically once connected to Bluetooth and, “oh yea!” it measures weight with accuracy and consistency.

Although measuring fat using Bioelectrical Impedance Analysis (BIA) is not as accurate as some of the more professional methods, the Weight Gurus Scale was amazingly consistent in its fat percentage measurements. Not only did it give the same reading for the same subjects time and time again, but it also detected an average of 3.3% to 4.2% lower fat percentages when using different subjects with different fat contents. This means it is a consistent tracker of body fat percentage. You want to lose weight, yes, but more importantly, you want to lose fat. The Weight Gurus Smart Scale – 0375 lets you know when that is happening.

The Weight Gurus Scale performed beautifully. When we used the standard 50.0 lb weights to measure the accuracy and consistency of the scales, it was only off by one pound after nine weigh-ins. So in measuring 2,988 lb it was only off by 0.17%. That’s pretty much perfect, and far exceeds the needs of most people using it to track weight.

Weight Gurus - Accuracy

Now let’s step off the scale and move onto the app. The integration couldn’t have been easier, plus you can connect your data with FitBit, Google Fit, Apple’s Health app, Under Armour and more. If you’re sharing the scale with friends or family, they don’t get access to your results so privacy is yours to keep.

One of our favorite features (of both smart scales that had applications): you don’t need your phone to weigh yourself! You can see your weight, BMI, body fat, water and muscle percentages on the screen and it will store the data until your Bluetooth is connected, then sync automatically.

Cool side note: If you skip a day weighing yourself (or only do so once a week), the app will automatically input phantom weight measurements to show your estimated weights from the last time you weighed yourself.

Key takeaways

  • The smart Weight Gurus Smart Scale – 0375 allows you to use its app alongside others like FitBit and Google Fit.
  • It performed near-perfectly on both the accuracy testing and consistency testing only missing by 0.17% out of 2,988 lb.
  • Even though Bioelectrical Impedance Analysis is not the most accurate way to measure body fat content, the Weight Guru Scale was lower by 3.3-4.2% than actual, but very consistent with its readings.

Runner up smart scale: Yunmai

Yunmai
It’s a bit unfortunate for the smart Yunmai Premium Smart Scale that it had to be compared to the Weight Gurus Scale, because if this was the only scale you looked at, it would seem perfect. It syncs with other apps, you don’t need your phone to weigh yourself (it will sync once connected) and it’s accurate and consistent. However, it cannot sync with as many apps (only Apple Health, FitBit and Google Fit), and it is not as accurate in body weight or as consistent in body fat as the Weight Gurus Smart Scale (it measured body fat both higher and lower than the actual).

Runner up smart scale

Yunmai Premium Smart Scale

As the only scale that measured weight to within one tenth of a degree, the Yunmai Premium Smart Scale prove you with an easy-to-navigate phone application with integrations with most popular other apps.

However, the Yunmai Premium Smart Scale was the only scale we tested whose measurements were precise to the tenth of a degree (0.1 lb). All of the others were 0.2 lb increments. And it was perfectly consistent!

This is impressive, considering only half of the scales tested scored perfectly on consistency. Furthermore, its 4.5 star rating for accuracy of weight was because it was off by only 6.4 lb out of 2,988 (0.21%). That is nearly imperceptible when using it to track your body weight. So for practical purposes, this scale will fit almost all of your needs.

Key takeaways

  • This Yunmai Premium Smart Scale was perfectly consistent in weight measurements and has a great phone application, allowing you to easily sync with FitBit or Apple Health.
  • It is the only scale that measured to such a precise degree (0.1 lb as opposed to the normal 0.2).
  • Although its body fat measurements were above and below the actual, they were quite precise measurements: 2.6% below and 1.7% above.

Best standard scale: Etekcity

Etekcity
The Etekcity – EB4074C performed perfectly in the accuracy testing and was consistent throughout. It’s clear glass is eight millimeters thick and stands atop four high-precision sensors. Its mini legs have a non-slip rubber material that makes it safe to use when on those more slippery hard surfaces.

Best non-smart scale

Etekcity - EB4074C

The Etekcity Digital Body Weight Scale was the only scale we tested that scored perfectly on all measurements, it uses an eight millimeter thick clearish-green glass, and has non-slip pads at the bottom which are perfect for a bathroom.

This scale has one of the smaller screens out there at only 3.1 inches, but the bright blue background stays lit for eight seconds, allowing you to take a closer look if needed.

Like all of the new model scales, you can just step right on. It has an auto-zero function and has an automatic overload indication (and if that goes off you may want to look at the iDOO Jumbo – ES09-3089M that handles up to 440 lb).

As one of the only clear scales we looked at, you won’t have to worry about putting this one away between uses because it goes with almost any design. And there are two metal bars on the bottom which allow you to hold onto it and dry it off easily if need be. Also, the unit-button on the bottom is clear and easy to push, making it easy to switch from pounds to kilograms.

Key takeaways

  • For a non-smart scale, the Etekcity – EB4074C performs very well under pressure.
  • It uses four high-precision sensors and quad stability pad suspension that allows for accurate, consistent and safe weigh-ins.
  • It has a smaller screen, but the number will flash three times and stay put for eight seconds with a bright blue background.

Runner up standard scale: Vive

Vive
The Vive – DMD1002SLV is a very affordable standard scale with great performance. This scale was off by just over one pound out of nearly 3,000, which earned it a grade of 99.96% for its weighing ability. It seemed fitting to give it five stars for both accuracy and consistency.

As one of the most slim models we tested, this six millimeter-thick glass comes in a light silvery gray and a fresh black, both of which have a modern textured look. It is a great little scale and was one of the easiest to move back under the sink in between weigh-ins. It was sturdy and light with a firm capacity to stay put on slippery tile.

Runner up non-smart scale

Vive - DMD1002SLV

The Vive uses a thin and sleek six millimeter gray or black glass to weigh up to 330 lb. It was one of the top scorers in both accuracy and consistency, proving to be an high performing non-smart scale.

It only uses two CR2032 batteries (most others require four), but it seems to be at an expense: it can only weigh up to 330 lb. Another possible downside to this scale was a screen under three inches, though it is still very well backlit and easy to see for most of us.

Key takeaways

  • The Vive – DMD1002SLV receives an A+ for accuracy and consistency measurements (99.96% correct).
  • It is one of the slimmest models but can only weigh up to 330 lb.
  • The Vive is easy to move to and from a cupboard, though it has a very modern design in two colors.

Other finalists

Other Finalists

INEVIFIT – Smart Scale

We’re not quite sure what caused it, but the INEVIFIT Smart Scale had a bit of a hiccup during the standardized weight testing. If you check out the graphs you can see it was off by quite a bit for the 100 and 150 pound tests. Other than, that it was a top performer. This was the only smart scale that didn’t have a phone app to go along with it so tracking won’t necessarily be as easy as the others. Then again, if you weigh yourself regularly and have a decent memory this should do just fine.

Great other smart scale

INEVIFIT Smart Scale

As a newer company and less expensive smart scale, the INEVIFIT can carry up to ten users in the scale’s memory and uses its built-in detection technology so you don’t have to choose which user you are before weighing.

Something to keep in mind, however, is that the fat readings were significantly low. That being said, this was actually the most consistent smart scale when it came to measuring body fat. So if an app and the exact numbers don’t matter too much to you then this is a good choice. You can store ten users and it is able to detect the different user so you don’t have to choose yourself each time.

Kinzi – DBS-1000

Hello Accuracy! The Kinzi – DBS-1000 standard scale is sleek, affordable and is one of the most accurate and consistent scales we tested. It was only off by 3.8 total pounds of the near 3,000. The Kinzi runs on only two CR2032 batteries and weighs up to the standard 400 pounds. Another thing to note is its screen: 3.3 inches (one of the biggest we found).

Unfortunately the black backlight makes it a bit more difficult to read than the normal blue. Thankfully, however, the measurement stays on the screen for about 11 seconds, giving you more time than you’d need to read it from a closer position. Another not-so-hot aspect is the “non-slip” bottom legs. They were average at best and it was only one of a few that didn’t have great non-slip technology.

EatSmart – ESBS-01

Another standard scale coming in with the consistency we like to see is the EatSmart – ESBS-01. It was only off by 0.2 lb on the 100 lb weight test and 0.6 on the body weight test. Other than that, it scored well on accuracy.

The EatSmart Scale was one of the most inexpensive ones we tested (under $20) and had one of the biggest screens that held the number for over nine seconds on a blue backlit screen. It measured weight quickly too. Also, as a pleasant surprise, it came with a free body tape measure, which was made it easy to self-measure due to its construction.

IDOO JUMBO – ES09-3089M

Biggest scale

iDOO Jumbo - ES09-3089M

If you have large feet, weigh over 400 pounds or just like a bigger surface that is sturdy, then the iDOO Jumbo Scale is the choice. It has about a 30% larger surface area than a standard scale, weighs up to 440 lb and has the ‘stickiest’ non-slip pads for stability.

The last and biggest is the iDOO Jumbo – ES09-3089M. It’s made for those over 400 pounds, as it measures up to 440 lb. This scale also has the biggest base, with about 35% more surface area when compared to the others. The bottom of the scale also has very sticky non-slip pads.

The iDOO has a marble-like surface that, at least artistically, puts the others to shame. If you have bigger feet or just like feeling extra safe, we’d suggest this scale. There was a certain comfort experienced when stepping on this extra-sized machine.

Greater Goods – 0390

This was a very cleanly designed standard scale. The Greater Goods – 0390 scored very well on consistency and accuracy (off by seven pounds of 3,000). It has a 3.3-inch “big screen” display with a nice blue backlight. But your weight will only stay for five seconds after you get off (if you remain standing on the scale it will keep your weight lit up).

It’s another not-too-expensive option under $20. But that may come at an expense: the non-slip pads at the bottom don’t live up to their name. Also, it uses CR2032 batteries, which is not the biggest deal but it is little things like that that could leave you to want another model.

The bottom line

For all of you exercisers, weight-losers and health-trackers, the scale is an integral part of your life. The most informative and functional smart scale on the market is the Weight Gurus Smart Scale – 0375 as it integrates with almost any other health app or Smartwatch program and was 99.83% accurate on just under 3,000 pounds. Also, the body fat measurements were consistently low which means it can definitely be used to track you body fat.

There were, of course, others that performed well like the smart Yunmai Premium Smart Scale and standard Etekcity Glass – EB4074C. The former is a phenomenal smart scale that is precise to the tenth of a pound, and the latter was what you’d expect when buying a scale: perfectly accurate and consistent.

Top Pick: Weight Gurus Smart Scale - 0375

The Weight gurus Smart Scale is the best scale for tracking your weight, fat content and muscle mass due to its extremely consistent measurements and graphing ability in the application. This app is unparalleled in that it will work alongside pretty much any other health app you already have.
