We've tested bathroom scales for the past five years. This year we spent more than 30 hours comparing each scale for accuracy, consistency and ease of use. Our research showed that the Fitbit Aria Wi-Fi was the best bathroom scale overall. It gives some of the most accurate readings, returns consistent measurements, works with Fitbit's fitness apps, looks good in most bathrooms, and can help you tailor your fitness efforts to your individual needs – whether that means losing a few pounds or building muscle. You can also keep track of the food and liquid you consume using this scale's app.

Fitbit Aria Wi-Fi

The Fitbit Aria is one of the best smart scales on the market. It connects to your home's Wi-Fi so it can record your weight and sync it to your online Fitbit account each time you step on the scale. It also works with popular third-party apps such as MyFitnessPal. It is both Mac and Android compatible, so even a household with mixed technology needs can all make use of it. The warranty only lasts for one year, which is shorter than average.
There are slots for up to eight users, so you can share this device with others in your household. It automatically recognizes which user is stepping onto it and will show your name or initials before displaying your weight and other information. There is little risk of others accessing your health information because your account is password-protected. This scale has a lower weight limit than most, with a threshold of 350 pounds. This was one of the most accurate and consistent scales we evaluated, so you can trust the numbers it gives you. In addition to reading your weight, it also tracks your body fat, BMI, glucose levels, blood pressure and activity levels. You can get some of these measurements for free; others require a subscription to use. The app also helps you document your food and exercise for the day so you can determine how many calories you have consumed and how many you have left to use. When it comes down to it, this scale can help you maintain a healthy lifestyle.
Pros
  • It records your weight and syncs it to your Fitbit account.
  • You can track your food intake and exercise.
  • You can track glucose, blood pressure and activity levels.
Cons
  • It's on the pricey side.
  • It only has a one-year warranty.
  • The weight limit only goes up to 350 pounds.

Best Value

Yunmai Premium

The Yunmai Premium scale costs almost 50 percent less than the top product, which makes it a highly affordable smart scale. In our testing, it provided accurate and consistent weight readings and was easy to set up and use. It can record information for up to 16 users, so you can share this device at work or with your household. Each time a user steps on the scale, their weight gets synced to their Android or iOS device. After enough data has been added, you can view your health stats in charts on the app. Unfortunately, it only shows you weight and body fat percentage in graph form.
Using the app, you can set goals and choose what information you share with friends and family members. This app, while initially difficult to learn, can also help you keep track of your BMI and body fat percentage. Unfortunately, it doesn't record calorie intake, but it can help you track the amount of water you consume. This scale has one of the best warranties on the market, spanning five years. You can choose between a white or black design. The scale is attractive and will fit in most bathrooms. It is by far the heaviest scale we tested, weighing 6.8 pounds. It requires four AAA batteries to work. With dimensions of about 13 inches wide by 13 inches long, it can accommodate people with larger feet.
Pros
  • It comes with a five-year guarantee.
  • It consistently reads your weight accurately.
  • It syncs with popular third-party apps.
Cons
  • It doesn't track calorie intake.
  • The app is a little difficult to learn.
  • It only creates graphs to show your weight and body fat.

Best for Consistent Readings

Weight Gurus

The Weight Gurus Bluetooth Smart Scale gives accurate weight readings and is the most consistent scale of any we tested. No matter how many times our testers stepped on it in immediate succession, the number it showed was the same.
It has a maximum weight limit of 400 pounds to accommodate people with a wide range of weights. You can have up to eight user accounts linked to the scale, so you and your household can all use it and have it sync your data to your mobile devices. Unfortunately, you must have an account to use this scale. Should a guest use it, it will try to record that guest's weight to an existing account. This scale comes with its own app but can also pair with Fitbit, Apple's Health app, Google Fit, Amazon's Alexa app and MyFitnessPal. The scale measures and documents your body fat, lean mass, water weight, bone mass and BMI. The Weight Gurus app doesn't allow you to track your fitness or your caloric intake, so you will need to use a separate app to track that info. It takes four AAA batteries to run, which is typical for this kind of scale. It measures 12.6 inches long by 12.6 inches wide. It also comes with a five-year warranty, one of the best we've seen for this kind of device.
Pros
  • It can sync to third-party apps.
  • It can handle up to 400 pounds.
  • The scale is covered by a five-year warranty.
Cons
  • It doesn't measure caloric intake.
  • It doesn't track your water intake.
  • You must create an account.

Why Trust Us

We’ve tested bathroom scales for the past five years. In our most recent testing, we compared 10 scales for more than 30 hours looking for products that offered the best accuracy, ease of use and the most consistent readings. Our testers were a group of men and women of varying heights, weights and body types. We used their information to compare each scale's ability to measure body fat percentage, weight and body mass index (BMI). In order to simulate weight gain and weight loss, we had our testers carry various free weights onto the scales.

We thoroughly tested each scale's app to see what features it offered and what fitness information it recorded. We also checked the scales for compatibility with third-party apps and listed the ones they could pair with. 

How We Tested

In order to test accuracy, we had our testers carry free weights onto the scales to see if the numbers accurately displayed the change. All of the scales except one measured within one pound of the user's weight. The more accuracy a scale achieved, the higher it scored in our evaluation. We also scored scales higher if they could handle more weight. The typical weight limit for most scales is around 400 pounds.

Since consistency is the only way to get accurate readings, we had our testers repeatedly step on the scales in quick succession to see if they gave the same weight each time. The most consistent products scored higher than the others. We looked for various features, such as the number of user accounts a scale allowed, the various fitness metrics it recorded and the length of the warranty it came with. Scales that worked with both Apple and Android devices scored higher.

While evaluating an app's ease of use, we looked to see which health data was visible in chart and graph form. The more options it provided, the better. We looked for calorie and fitness trackers, as well as any additional body stats like BMI, muscle mass, bone density and hydration levels. We also scored scales on their overall appearance. We scored scales higher if they were aesthetically pleasing while not drawing attention to themselves. 

Final Thoughts

Most smart scales connect to your Wi-Fi in order to sync to your mobile device. Some only allow you to use the scale's proprietary app, while others can also sync to popular third-party apps such as Apple Health, MyFitnessPal, Amazon's Alexa app and Google Fit. You typically need to create a user account for a smart scale to work properly. The user account maximum can vary from as few as one to an unlimited number, so you should make sure the scale you buy can accommodate your household. These scales can sometime identify who you are the minute you step on them and send the data to your phone, making updates incredibly easy.

In addition to measuring your weight, many smart scales measure body fat, lean mass, BMI, water weight and bone mass. Some even provide graphs and charts of your progress as you use them. Some apps are more user-friendly than others, but most of them allow you to set goals and reminders to help you stay on track. These scales are designed to protect your privacy from other users, so your information is only shared if you want it to be.

You should look for a scale that doesn't look out of place in your bathroom and won't get in the way of your day-to-day tasks. Most scales are around an inch tall, but they vary when it comes to length and width. Smaller scales can fit easier in a room, but they might not feel as comfortable for people with larger feet. The best warranties typically last for five years or more.
