Buying guide for Best digital scales
Whether you’re trying to lose or gain a few pounds or simply want to know your current weight, a digital scale is an easy way to get that information.
Not just for monitoring weight-loss journeys, digital scales can also help you to track hydration levels before and after a hard run, monitor a child's growth, and even check on your pet’s weight between vet visits. Some also come with features that allow you to chart your progress and determine your body mass index (BMI).
Key considerations
Digital vs. analog scale
Why choose a digital scale over an analog model? First, digital scales are much more accurate than analog units. On an analog scale, a bit of movement can send the dial one way or the other leaving you with an ambiguous reading. Analog scales are also more difficult to read. Numbers on a digital scale’s display are clear and simple to see from a distance. Many digital scales even log previous readings, so users can check on their progress without having to write everything down manually.
Metrics
If you’re merely interested in how much you or some other person or object weighs, there are plenty of basic digital scales that provide weight data in pounds or kilograms. Interested in learning more about your body composition? Some scales also provide metrics such as BMI, body-fat percentage, bone mass, muscle mass, and basal metabolic rate.
Ideally, a digital scale should have a roomy and comfortable platform. We decide if the platforms of the models we consider fit this criteria.
We evaluate the weight limit of a digital scale, noting that capacity varies among models. It’s common for a scale to have a weight limit of 300 pounds.
Because stability is important when using a scale, we want to know if the models we consider have slip-resistant surfaces and bottoms. These features are especially important when a scale is used in wet conditions.
Consumers need to know if a digital scale’s display is easy to read. Are the numbers vivid and large? Is there a backlight? We look at these features in our research.
We assess the metrics a scale measures. Some models only provide weight readings; others deliver more comprehensive information, such as muscle mass, BMI, and metabolic rate.
Digital scales run on batteries. We note the type and number of batteries needed to power each scale on our research list.
Because accurate readings are important, we examine the scales we select for accuracy, noting that digital scales tend to be much more accurate than their analog cousins.
We understand that some shoppers may be concerned about the aesthetics of a scale, and we keep this in mind as we cultivate our list of the best digital scales.
Many modern gadgets are available in smart models, and digital scales are no exception. We take note when a scale has Bluetooth or WiFi connectivity that can be paired with a smart device.
Some high-end scales can store the profiles of multiple users. This is a feature we look for when critiquing digital scales.
Features
Power source
Digital scales run on battery power. You can find models that require AAA or AA batteries or a single cheap coin cell battery.
Size
A scale’s platform should be comfortable to step on. You shouldn’t have to squeeze your feet onto the surface. Choose a scale with a wide enough platform for your body.
Display
The display on a digital scale should be large and bright enough that you’re not having to bend over and squint to read the numbers. A backlight makes reading the display a lot easier.
Smart features
If you use fitness technology, such as a Garmin watch or Fitbit, some digital scales transfer weight data via WiFi or Bluetooth to apps, so users can keep track of progress with charts and graphs.
User profiles
If you have multiple people who want to use the scale in a household, consider choosing one that supports multiple user profiles. Some models will even automatically recognize individuals as soon as they step on the scale and will keep other user data private.
Whether your scale supports one or more users, models that provide BMI and other metrics will ask you for information such as your height and weight to make appropriate calculations.
Slip-proof bottom
Most scales end up permanently living in bathrooms. To prevent slippage due to condensation and moisture, choose a scale with a slip-proof bottom. For added safety, pick a scale with a textured platform.
Athlete-specific settings
Some scales allow users to select an athlete profile when entering user data to account for increased muscle mass.
Upper weight limit
Most scales have a weight limit of 300 pounds, but this maximum varies widely. Check product descriptions to ensure you pick a scale that can accommodate your body weight.
Digital scale prices
Inexpensive: You’ll find loads of digital scales for under $25 that provide various metrics, such as BMI and body-fat percentage. Cheaper scales, however, are not always accurate or as durable as pricier options.
Midrange: For a scale that tracks progress for multiple users, expect to pay at least $35.
Expensive: A digital scale with smart features designed to function with a specific fitness tracking platform or device will cost you more than $100 in most cases.
Tips
Keep a routine. Weigh yourself at the same time each day. If your first weigh-in was done in the nude, continue this trend. Remember to remove any jewelry or accessories you don’t regularly wear. Also, don’t move the scale around from room to room; keep it in the same place.
Carefully step on the scale. Some models have outlines to help you position your feet properly to ensure you get an accurate reading. Read the instructions that came with your scale for specific positioning guidelines.
Change the batteries. Does the weight reading seem entirely off? Swap the batteries for fresh ones, and weigh yourself again.
- Choose a steady surface. Place your scale on a hard, level surface. Keeping it on a rug or a bathmat can alter your reading.
FAQ
Q. What is BIA (bioelectrical impedance analysis)?
A. Certain scales that measure metrics, such as body-fat percentage and water content, use BIA technology. Via electrodes (which you either place your feet on or hold in your hands), an electrical current passes through the body and provides data estimates for the metrics in question. BIA is not very accurate, but keeping track of downward or upward trends in body-fat percentage or bone mass is still useful. We just recommend not paying too much attention to the exact numbers.
Q. How do I clean my scale?
A. Often housed on the floor in a humid environment, digital scales tend to pick up dust and grime quickly. It’s important to clean off your scale regularly. A quick wipe with a moist paper towel or microfiber cloth should do the trick. If you’re concerned about germ buildup, use an antibacterial wipe to clean the surface, especially if multiple users are using the same scale. Never immerse your digital scale in water.
Q. I’m trying to improve my fitness and lose weight. Which metrics should I most pay attention to?
A. Keep track of the trends in your body-fat percentage and muscle mass. Take progress photos and body measurements, too, to get a better picture of how you’re doing. (However, if you’ve ever dealt with an eating disorder or other disordered behavior related to body image, a scale may encourage compulsive behaviors and may not be right for you.) Ultimately, how you feel is much more important than any number on a scale.
