Best Body Fat Monitors

Verywell

Making positive lifestyle changes can start with health and fitness. And if you’re looking at physical measures to help you in your journey, body fat monitors can offer data to support your goals. While many people are hyper-focused on weight and body mass index (BMI) as indicators of wellness, experts say that body fat percentage reveals even more about a person’s health.

Body fat monitors are reasonably priced and easily fit in a bathroom corner or your gym bag. “When choosing a body fat monitor, it’s important that you choose one that fits your lifestyle,” says Kim Mahony, RD, LDN, Corporate Manager of Nutritional Services of Lutheran Life Communities. She notes that they all have accuracy limitations, but that you should be safe as long as you measure using the same method every time. 

Mahony explains that even if a method or tool isn’t 100% accurate, you’ll be able to track your body composition over time which will help you set personal goals. 

Here are the best body fat monitors on the market.

Withings Body + Body Composition Wi-Fi Scale

Withings Body Scale
5
Pros
  • Accurate readings

  • Auto user recognition

  • User-friendly

Cons
  • Expensive

  • App needs improvement

This body fat monitoring scale is an excellent option for the tech-savvy user who is looking for both goal-setting assistance and a sense of accountability. It uses bioelectric impedance to analyze your full body composition, stores data for up to eight people, and automatically recognizes those people when they step on the scale. Then, it syncs with the Health Mate app, which tracks all of these wellness data points over time so you don’t have to record anything manually.

Connecting to the app and setting up the scale is simple and easy, and the app hosts a slew of special features for anyone interested in really digging into the many aspects of their health.

Key Specifications

Style: Scale | Data memory: Up to eight users—data points stored in app | Smart features: Syncs with health apps via WiFi

What Our Testers Say

“The scale’s ability to connect to your phone takes it a step above the scales of yesteryear. After the initial setup, the scale automatically sends all measurements to your phone within a few minutes of weigh-in. The ability to track your fitness progress without any manual charts or extra work allows you to focus completely on getting the results you’re after.” Wendy Bumgardner, Verywell writer and product tester 

EatSmart Digital Body Fat Scale with Auto Recognition Technology

EatSmart Precision GetFit Digital Body Fat Scale
Pros
  • Precise measurements

  • Displays English and metric units

  • 400-pound weight capacity

Cons
  • Doesn't store data points

  • Doesn't measure BMI

This scale uses bioelectric impedance to estimate your body fat percentage, muscle mass, bone mass, and total body water, in addition to measuring body weight in 0.2-pound and 0.1-kilogram increments. It can support up to eight user profiles, but it does not store any scale data for those users.

After you set up your profile with the scale—providing your height, age, gender, activity level, and an initial weigh-in—it automatically recognizes you when you step on in the future.

For ideal results, stand on the scale in bare, dry feet whenever you want a new reading. And remember that people with pacemakers should not use bioelectrical impedance body fat monitors due to the (otherwise harmless) electric current they require to take a measurement.

Key Specifications

Style: Scale | Data memory: Up to eight users, but no data points | Smart features: User autorecognition

What Our Testers Say

“Besides telling you your weight in units of 0.2 pounds or 0.1 kilograms, this scale also uses a small electric current to measure body fat, water, muscle, and bone mass.  Up to eight users can store their profiles on the scale and the scale will automatically recognize which person is using it. The scale performed well, but I found myself missing having it display a body mass index.” Wendy Bumgardner, Verywell writer and product tester

With only five buttons, it’s simple in design and easy to control. It can also store up to nine user profiles and displays new readings in a matter of seconds. It’s a relatively new product with few reviews, but for the price, it’s worth a try.

Lightstuff Precision Skinfold Caliper
Pros
  • Includes quick-start guide

Qiorange Digital Display LCD Body Fat Caliper Skin Fold Analyzer

Qiorange Digital Display LCD Body Fat Caliper Skin Fold Analyzer
Pros
  • Best for measuring body fat around the stomach

  • Easy to read and understand

Cons
  • Slightly uncomfortable

Want to combine the skinfold assessment method with an easy-to-read digital display? Check out these Qiorange calipers. They are primarily designed to provide a body fat percentage reading by measuring subcutaneous fat specifically around the stomach, but you can still physically measure the other areas of your body typically included in comprehensive skinfold assessments.

For ultimate accuracy, some users recommend measuring the same area with the same technique three times and taking an average of the reported results. These make skinfold assessments more accessible to folks who don’t have a person available to help them use traditional calipers. In addition, the LED display is large enough for easy reading.

What to Look for in a Body Fat Monitor

Style

There are three main styles of body fat monitors on the market today—scales, handheld devices, and skinfold calipers. Each style is used differently (and provides varying levels of accuracy) to give you a snapshot of your current body fat percentage, so consider which works best for your lifestyle, preferences, and goals before making a purchase. Scales are home-friendly, handheld devices are ideal for your gym bag, and calipers generally don't require an app or batteries to use.

Measurement

Handheld monitors and scales often use bioelectrical impedance analysis (BIA) to measure body composition by sending weak electric currents through the body. While these devices make measuring body fat at home easier and more affordable, Lauren Hubert, MS, RD, says they come with limitations. 

“Not only is BIA impacted by your hydration, but it also tends to overestimate body fatness in lean and athletic individuals and underestimate body fat in obese individuals,” she says. Because of this, Hubert says it’s best to use these devices as a tool to monitor change over time. 

Skinfold calipers require self-measurements instead of automatic measurements. Hubert warns that they can be difficult to use if you’re not clinically trained to use them, so your measurements can come with inaccuracies.

Data memory

Most digital body fat measurement devices can store a certain amount of data entries and organize them per user, but this capacity varies dramatically from tool to tool. Such data memory helps users analyze potential trends in body fat percentage changes, further supporting new wellness and lifestyle goals. But if you plan on sharing the device with another person, be sure it offers memory storage for at least two users to keep all data organized and separate.

Smart features

“If a scale or body composition machine comes with smart features like Bluetooth connection, I think that is a fantastic tool to track your readings,” says Hubert. Luckily, most modern body fat monitors on the market today have the ability to sync with your phone via either Bluetooth or WiFi, making it easier to keep track of your health goals no matter where you are. 

If you’re really into data, review the specific technical capabilities of a body fat monitor you’re considering before you buy it. “Having the ability to track your readings as months go by is an amazing way to keep track of your progress and statistics,” notes Hubert. However, she advises against recording your body composition daily since the smart features are designed to track changes over longer periods of time.
