Usually, a “best of” list needs little explanation beyond the title. But when it comes to the best bathroom scale, we may have to carefully define our terms. Does “best” mean most intuitive functionality? Coolest design? Most accurate?

We doubt anyone invites people up to their bathroom to check out their stylish, state-of-the-art new scale (but hey, you do you!), so accuracy would seem to be the obvious starting point.

But as we know, fitness is a lifestyle, and everything from our shoes to our water bottles is interconnected and working with us towards our goals. So we’re going to define the “best bathroom scale” as the most well-equipped to engage in your healthy lifestyle with helpful and practical data.

One thing to note, however, is that while some scales provide metrics beyond body weight, their readings can be inaccurate. The more granular the data a device claims to mine, the more likely it may be stepping into murky accuracy waters.

To that end, here are the best smart scales available in 2022.


1. Withings Body Cardio

Withings smart scales rank high on just about every list of the best bathroom scales, thanks to their insanely sophisticated data tracking and sharing capabilities. (And while that could mean posting your weight on Twitter, it doesn’t have to unless you want it to — and why would you want it to?)

The Withings Body Cardio is the company’s most advanced smart scale. It syncs easily with Apple Health, Fitbit, and Google Fit, and every weigh-in is stored in the Health Mate companion app so you can easily share with your doctor.

That data includes your weight and approximate BMI and body composition. But the feature that really sets the Body Cardio apart is its 30-second “cardio check-up,” which approximately monitors your heart rate and roughly estimates your vascular age.

2. QardioBase 2

The QardioBase 2 ranks so highly because it’s sensitive in more ways than one. Not only is it accurate down to 0.2 pounds, but it also offers a “Smart Feedback” mode that replaces numbers with emojis — so you can choose to gauge your progress without stressing about the number on the scale.

This smart scale measures weight and approximate BMI and body composition, and sends the data to the free Qardio app on your phone or tablet. The app can also be used to set achievable goals and calculate weekly targets.

QardioBase 2 is also one of the best bathroom scales if you’re expecting. It features a “Pregnancy Mode” that lets you select your due date and track your progress throughout each trimester — and even add photos of your growing bump.

Get it on Amazon.


3. FitBit Aria Air

Praised for its accuracy and consistency when measuring basic metrics like weight and approximate BMI, this scale earns bonus points for how seamlessly it fits into the “health and fitness ecosystem” created by all of Fitbit’s products. Your stats sync wirelessly to your Fitbit dashboard, so you can track your progress over time.

This scale may not go as deep as others with its measurements, but that’s not an issue for many users. If you’re not super-concerned with measuring your bone mass or body water percentage, this is a solid, budget-friendly way to monitor your weight.

4. Garmin Index S2 Smart Scale

Garmin updated their popular Index Smart Scale to be lighter and less bulky, with a high-resolution color display that shows your weight, body water percentage, body fat percentage, bone mass, muscle mass, and BMI — albeit approximately.

These metrics are seamlessly synced to the Garmin Connect app. If you’d rather keep it simple, you can also use the app to customize which metrics are displayed on the scale.

A graph of your 30-day weight trend can be viewed on the scale’s display, or you can track your progress over longer periods using the app. And for runners who rely on a Garmin fitness tracker, this smart scale can help you see the bigger picture of your overall health and your performance goals.

5. iHealth Nexus Body Fat Scale

This budget-friendly option is one of the best bathroom scales for anyone who’s kickstarting a healthier lifestyle.

Four sensors use bioelectric impedance analysis to monitor weight and body composition across nine different data points. That includes the usual suspects, like weight and body fat percentage — but it also provides an estimate visceral fat rating and a recommended daily calorie intake to help you get a more complete picture of your overall health.

Data syncs through Bluetooth to the free iHealth MyVitals app, which generates charts and trends to help you keep tabs on your progress.

How Accurate Are Smart Scales?

A lot of smart scales boast of their ability to measure body fat, but experts feel there are too many variables to guarantee an accurate reading, even with the top models.

Research suggests body composition measurements taken through the feet may be affected by factors like foot size, sweat, and position on the scale. And a recent study compared three smart scales and found they were relatively accurate when measuring weight, but all three scales underestimated body fat.

It’s also important to take BMI measurements with a grain of salt. Even when perfectly accurate, BMI is only based your weight and height — it doesn’t represent your muscle-to-fat ratio.

So when considering a smart scale, lean towards accessibility, ease of use, a user-friendly app, and the ability to track your progress above selling points such as “body water” or “bone mass.”

Bottom line: Go with what best integrates into your overall lifestyle.
