Best bathroom scales 2021: Including the top smart scales

The best bathroom scales for measuring body weight, plus smart scales for tracking BMI, body fat and water weight.

The best bathroom scales do so much more than just measure your body weight, as they can also keep tabs on your BMI, body fat, water weight and bone density. Also, known as smart scales, a good bathroom scale keeps you on top of your health concerns, and in our guide we’ve included a range of analogue, digital and smart scales, whether your aim is to lose weight, maintain weight or to gain weight. Some bathroom scales even keep tabs on your body temperature, though we’d recommend one of the best digital thermometers here instead.

The best bathroom scales are battery operated, so you can happily forget about having to charge them. As for smart scales, these are made by well-known health brands such as Withings, QardioBase and Fitbit (who also make the best fitness tracker). These smart scales can also pair with a companion app, which you download onto your phone to help keep track of your essential data, alongside other health metrics. Using digital scales with an app also helps you see more clearly when you are losing or gaining weight. If, however, you prefer to keep things old-school, then Salter is known for their reliable analogue bathroom scales.

According to a 2016 study, weighing yourself once a day can help maintain your ideal weight, alongside a good fitness regime, proper nutrition and adequate sleep, each of which are important in helping us achieve a healthy body weight and BMI. If you’re looking for the best bathroom scales to use as part of an at-home training regime, there are now plenty to pick from, starting with the below. To further your fitness goals, we’d also recommend the best treadmills for indoor running and walking, or an elliptical machine or home gym for full body workouts.

Smart scales are great for tracking health and weight, but if you are pregnant it's wise to pick bathroom scales that don't use Bioelectrical Impedance Analysis (BIA), a technology that some smart scales use to monitor weight and other health metrics. BIA doesn’t have any known health risks (though if you have a pacemaker, check with your doctor before using a scale containing this tech), but as an added precaution it is still recommended for pregnant women to avoid it. That's why the QardioBase 2 smart scale includes an in-depth pregnancy mode, which enables moms-to-be to track their weekly weight. That, and you can add in photos of your growing bump for a quick and fun visual reference that you can look back on. Simply connect to the free Qardio app and you’ll be good to go in terms of monitoring your weight and documenting your changing body. Another plus with the QardioBase 2 bathroom scale is that it's powered by a rechargeable battery that lasts 12 months between charges. That's plenty to see you through a pregnancy and beyond, making it the best bathroom scale if you don't want to fuss around with batteries. Ever.

This is a smart, simple scale that does exactly what you need it to, and for everyone in your house.

How we chose the best bathroom scales

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.

How to buy the best bathroom scales for you

Over the years, we have tested bathroom scales ranging in price from around $20 to over $250, with an average price coming in at around $140. Pricing is often based on a scale’s biometric readouts, its tracking capability, connectivity and associated apps. Generally, the more features and smarts a bathroom scale offers, the more it will cost you. Here’s what to keep in mind when shopping for the best bathroom scale for you… 

Connectivity
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.

Biometrics
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.

Aesthetics
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.

Bathroom Scales

Bluetooth bathroom scales vs Wi-Fi scales

There are two wireless connectivity options for sending information from a smart scale to a mobile app: Wi-Fi and Bluetooth. The primary advantage of using a smart scale with Wi-Fi connectivity is that you don’t need to have your phone or fitness tracker near the scale to log a weigh-in.

Some of the Bluetooth scales we tested save the data until the next time you sync the device, but most of the cheaper Bluetooth scales do not. Wi-Fi scales send all the data a smart scale collects to fitness-tracking apps, regardless of where the device is located.

Another advantage of Wi-Fi scales is connection stability. Although the setup is a bit more involved for Wi-Fi smart scales, once these scales are connected to your home network, Wi-Fi connections are much more reliable than Bluetooth syncing. We noticed a huge volume of customer complaints about constant syncing issues with Bluetooth scales, even the ones that save data.   

The only reason to consider a Bluetooth smart scale over a Wi-Fi scale is the cost. The best Bluetooth scale we tested is less than $50, and there are several cheaper models available. In contrast, the best Wi-Fi scales in our test group range from $100 to $200. If you are serious about tracking your weight using a smart scale and companion fitness app, we suggest using a Wi-Fi-enabled scale because it will ensure consistent tracking without requiring you to keep your devices close by.

Best bathroom scales: What is body composition?

Some scales measure more than just your body weight. Body composition is an important aspect of your overall health, as your weight is made up of not just fat, but muscle, liquids and other things that are an important part of keeping you healthy. 

Some scales measure your body composition and will tell you how much fat, protein, minerals and water your body is made of. This way if you’re trying to shrink your waistline you can watch for your fat mass to decrease while your muscle mass increases. Seeing your overall weight increase a little isn’t always a bad thing, as muscle mass weighs more than fat.

Having a very high percentage of fat in your body can cause health problems including hypertension, respiratory issues and gallbladder disease. Using a scale to tell you how your body weight is broken down can be an extremely important tool for staying healthy and avoiding doctor visits. 

Using a body composition scale to monitor your muscle growth can also be extremely helpful for athletes or those participating in professional bodybuilding. Knowing what’s going on inside your body is key to meeting your weight or fitness goals, and body composition is a big part of that.

How to clean bathroom scales

It’s easy to forget about your bathroom scale once you find a place to keep it. However, you should keep it clean so that it continues to be accurate and quick. Use a small brush or cloth to wipe away dust weekly, and keep the surface of the scale clean. If this doesn’t quite do the trick, try using a damp cloth. 

It’s important not to get the scale too wet, particularly if it has batteries. Clean gently; pressing too hard on the scale’s pan can mess up the weighing mechanism and cause your scale to display incorrectly. 

Never turn it upside down and apply a lot of pressure. If you’ve removed the batteries for a while, it’s important to calibrate the scale when you reinstall the batteries. Some scales do this automatically, but others include instructions for how to do so. 

Finally, to make sure your scale gives you an accurate readout, weigh the same item repeatedly and ensure the readings are identical. As with any household appliance, keeping your scale clean and free of debris will give it a longer and more useful life.
