Best Body Fat Scales | 2021 Buyers Guide

If you’re serious about losing weight or gaining muscle, an ordinary set of scales may not be enough and you might need one of the best body fat scales featured below. Standard scales record only your weight; they don’t tell you about your muscle definition, your body fat percentage, or the progress you’re making.

Thankfully there are a number of devices out there that will perform these functions for you. They can even save your data (and that of your family members if they’re also looking to make gains). The most accurate body fat scale will ensure that you're well aware of your body's measurements so you can get a better hold of your health, regardless of if you are losing, gaining, or maintaining.

So, if you’re looking for a more advanced scale that measures body fat, read the list compiled by our expert researchers below.

Criteria Used for Evaluation

Features

You can never go wrong with a little extra if you know you will use it!

Yes, all of the selections on our list are body fat scales, but that does not mean that is all that they measure. In fact, a lot of the selections on our list offer several body composition metric measurements that will help you get a hold of your overall health. When we took a look at the features each scale offered we evaluated the factors below--but make sure you evaluate these based on whether or not you will use them especially if you're looking for the most accurate body composition scale and this feature is important to you.

Different measurement features

Here we will go over some of the additional metrics that will be measured by many of the scales on our list of reviews. Not only are these benefits, but if they are useful for you they are totally worth looking for in a body fat percentage scale.

Water weight. Many scales will track your water weight each and every time you weigh yourself. This will help you compare your weight to your body fat and see how much of it is actually just water. Yes, your body fat will tell you how much of your weight is actually fat, but this will help you get a better gauge of how your weight is distributed.

Visceral fat. This is the percentage of fat that surrounds your organs and is an excellent gauge of how healthy you are on the inside. You want to keep this number at 5% or below, ideally.

Muscle mass. This feature will allow the scale to provide you with details about your muscle mass so you know just how much your muscles weigh in comparison to the rest of your body.

Bone density. This measurement is especially important to women and anyone over 40. It provides you with your bone density and will help you keep track of where you stand in terms of bone health.

Long term tracking

Another great feature to look into is long term tracking. This feature will ensure you can go back and look at where you were and where you are now--so you can see your progress from the very beginning. This is a great motivator, so if you know you are someone looking for an extra push anywhere you can, then this is a good way to go.

Multiple user tracking

If you have a busy household and only want to use one scale, this is the feature to look out for. Some body fat percentage scales may only track one or two users, but there are others that can track up to 10 users. Make sure you take a look at this feature specifically if you want a scale that will work for everyone!

App compatibility

Some of these body fat analyzers come with accompanying apps that you can access through your smartphone--and some even through your smartwatch. These apps will often track so much more than just your weight and help you see all of your stats from the very beginning so you can continually track your progress over time.

Accuracy

Make sure you are getting accurate measurements so you know where you really stand.

It’s important to consider how accurate the data provided by the scales really are. The best body fat scales provide readings which are accurate to within only a few pounds, many of them harness a technology known as bioelectrical impedance, which measures the resistance of electrical waves as they flow through the body to gauge a person’s fat levels.

It can be hard to determine belly fat since the waves are measured in the lower half of the body. Other factors like hydration, the time of day, and even a woman’s menstrual cycle can affect the accuracy of the reading. Because of the use of bioelectrical impedance technology, many of the best body fat scales are not safe for pregnant women or those with pacemakers.

A lot of the body fat percentage scales in our list of reviews offer additional metrics such as water weight, muscles mass, visceral fat, and much more. It is important to take all of these measurements into consideration when you calculate your weight, so make sure you calibrate your scale whenever necessary. Always use it in the same spot to get a consistent measurement each and every time.

Use

Make sure the scale measures the metrics you want to measure and is easy enough for you to use.

The body fat percentage scales on this list weren't chosen based on their brand popularity or whether they are the latest models to hit shelves. Instead, we conducted in-depth research to determine the best options on the market. To find the best scales, we made sure they deliver accurate body composition stats, while also being user-friendly. Each of the factors used to evaluate the use of each of the best body fat scales is explained below.

Why measure body fat?

Using a smart set of body fat percentage scale provides users with a panoramic view of their physical health because they can see a full suite of body composition metrics including weight, BMI, and muscle mass. This enables them to take control of their weight loss journey and track their progress because they know what the breakdown is.

Body Fat vs. BMI

Although many scales measure body mass index (BMI), these two metrics are not the same. BMI refers to the measure of body fat based on a person’s weight in relation to their height. Body fat percentage is how much fat is in the body. It’s found by dividing the fat mass by body weight. Since BMI doesn’t take into account the weight of muscle and bone, body fat is a much better indicator of finding a healthy weight for each individual.

Ease of Use

Last but not least, we took a look at how easy to use the scales we evaluated actually are. Yes, most of them you just step on and, voila, there are all your details. Rather we considered how easy the body fat analyzer is to read and navigate through and if it has an app, we also considered how easy it is to access and get accustomed to.

Connectivity

How reliable is the body fat scale?

With smart capabilities comes a whole new world of factors to consider when choosing a body fat scale. A few decades ago we would have never thought to consider the connectivity of the scale--let alone all of the other features they have to offer. When we evaluated each of our selections based on connectivity, we took several factors into consideration.

How "smart" is the device?

Not all of the scales on our list are fully "smart" body fat analyzers. What we used as a defining factor here is whether or not the scale is able to transmit data via Bluetooth or Wi-Fi. This typically means you can connect the scale that measures body fat to your smartphone and that the scale also has an accompanying app that you can download and use. This app will allow you to track your progress and many other features.

App compatibility

As we mentioned, a smart scale will have an accompanying app you can download and use as well. Aside from that, however, many scales may be compatible with third-party apps like Apple or Google health, MyFitnessPal, and much more. If =they are compatible with third-party apps, we evaluated whether or not they are able to connect with multiple apps or not.

How reliable is the connection?

To assess the reliability of the connection we took a look at user reports to learn whether or not there were any consistent connectivity issues reported by real-life users. This meant looking at issues with the Bluetooth connection and Wi-Fi connection problems not associated with the individual's isolated Wi-Fi router.

Capacity

What can the scale handle? Will it hold up to your needs?

Before deciding whether or not the scale deserved a spot on our top 10 list, we evaluated and rated each pick based on how much it can handle--AKA, its capacity. When you get a scale, you want to make sure it can handle your needs in every way, to ensure you are getting a scale that works for you to make sure you look at the following two features--that's what we did!

How much weight can the scale handle?

For the most part, scales can handle quite a bit of weight--however, there are some options that have a capacity of 300 pounds while there are others that can handle 500 or more. If you weigh less than 250 you probably won't have to worry too much about this (although you should still double-check) but if you weigh more you will want to make sure just because a lot of brands vary when it comes to this topic.

How durable is the scale's construction?

Here we asked ourselves how heavy and thick are each of the scales--yes, this is important! It's important because many people like to move their scales around or store them in other places. You want to make sure they are built of high-quality materials that are built to last and ensure that the scale will hold up to the use you will put it through.
