Our real-world tests were similar, in that we measured accuracy and precision in the same ways. The core difference in the real-world test is the duration of the test itself. Testing two bathroom scales at a time, we took the bathroom scales home, set them up with the accompanying apps on our phone, and tested our weight at least three times a week for a month straight. We made sure that we did so right after waking up, before eating or drinking. We recorded our notes on the display, ease of use, accuracy and throughout and at the end of the testing period. Although BMI isn’t always accurate and doesn’t differentiate between lean mass and fat mass, it can help you determine a healthy weight range for your height ( 3).

Although Bluetooth scales have a limited range and require having your phone nearby, the industry experts we spoke with insisted that for reliability and efficacy, this was a better alternative to Wi-Fi. So we prioritized scales that work with Bluetooth technology. FITINDEX’s Bluteooth Body Fat Scale did an incredible job with the tests we gave it. The scale was off by just 0.1 pounds in both our comparison test and our dumbbell test. So it proved to be the most accurate scale in this bunch. And our testers were particularly impressed by how user-friendly the scale was—giving it a perfect score for setup, a perfect score for display and readability, and a 4.5 out of 5 for ease of use.For those looking for a reliable scale with no complications or apps to maneuver the Mainstays Analog Bathroom Scale was the best budget analog scale we tested. Radley D, et al. (2009). Validity of foot-to-foot bio-electrical impendance analysis body composition estimates in overweight and obese children. Wider than your average scale, its display features large, high-contrast numbers that are easy to see whether it’s day or night. Standing up straight, the readability was incredible and the display was clear. We didn’t have to hunch over to read the numbers at all. There’s also a button that you can press so you can change the measurements from pounds to kilograms, which means the display measurements are versatile.

van Marken Lichtenbelt WD, et al. (2004). Body composition changes in bodybuilders: A method of comparison. The price, appearance, ease of use, and technological capabilities of your scale are other components to consider.That’s because healthy habits, like exercise, can build muscle. Increased muscle mass can make the number on the scale stay the same or, in some cases, increase, even if you’re losing fat and becoming more toned. Smart scales typically use either Bluetooth or a combination of Bluetooth and Wi-Fi. Wi-Fi scales generally cost more because they require more components to work. They're also much more convenient. INEVIFIT's Bathroom Scale was very easy to set up and has an auto-calibration feature but there’s no data storage and we found that the bathroom scale’s display was a lot easier to read in darker lighting. While it’s very sturdy and accurate, we couldn’t justify the price point of this scale in juxtaposition to the features it provides.

We feel that the price point is completely fair given how easy it was to use this sleek, stylish, and accurate glass bathroom scale. It also comes with a five-year limited warranty. The National Heart, Lung and Blood Institute notes that your risk for heart disease and diabetes increases if you are a woman with a waist measurement greater than 35 inches (88.9 cm) or a man with a waist measurement of more than 40 inches (101.6 cm). Calipers We tested the Etekcity EBS-C121-KIS Digital Body Scale, and the sleek, user-friendly design with its large, easy-to-read display made it our choice for the best overall bathroom scale. If we could describe this bathroom scale in one word, it’d be “seamless.” Some scales don’t have design at the forefront, but this bathroom scale doesn’t compromise style for simplicity or accuracy. The rounded corners and anti-skid padding make this bathroom scale durable, study, and a great cost-friendly investment.Throughout these tests, we also paid attention to other key attributes—like data storage, display and readability, and ease of use. And we assigned each bathroom scale a score (out of five) on each of those attributes. For data storage, we considered how many measurements the bathroom scale could record and how many users could log into the bathroom scale. (A high score in this category indicates a bathroom scale that can provide lots of measurements and handle many users.) The display was great. It takes about two seconds for your measurement to pop up on the screen and the clear, bright LED measurements were extremely easy to read even though this was a smaller bathroom scale. You can change the measurements from pounds to kilograms if you need to as well. The button is underneath the bathroom scale, so if you want to change it, we suggest doing that before you go to step on it. We think that the price point perfectly matches the bathroom scale’s capabilities and you can choose to extend your warranty up to three years.
