We decided to eliminate analog or mechanical scales (the kind with a dial) from consideration entirely. Mechanical scales have been shown to be significantly less accurate and less precise than digital scales, and Consumer Search says that analog scales’ delicate internal framework—small mechanical parts such as tiny springs—tends these scales toward wear and tear as well as misalignment. Mechanical scales also show weight increments of only 1 pound, can be hard to read, and need to be set to zero and recalibrated manually. They’re also a dwindling category: As of this writing, only 45 bathroom scales on Amazon are mechanical, compared with 665 digital bathroom scales.

Smart scales can be more than four times the price of regular digital scales. They aren’t necessarily better than all the other digital scales—they just have more connectivity features. More-advanced digital bathroom scales offer more insights into your health, such as an estimate of body-fat percentage, now considered a better indicator of health than weight alone or BMI (an estimate of body-fat percentage based on weight and height). Only a handful of basic digital scales offer body-fat or other body-composition (e.g., bone-density) readings, so if you want a body-fat percentage estimate, you’ll need to invest in a smart scale. There’s another important reason you might want to spend more on a smart scale compared with one that doesn’t connect to your phone or sync your data online: effortless weight tracking. After jotting down weight readings for a dozen scales over a couple of weeks, we quickly realized the benefits of having a smart scale automatically do the tracking. Gathering that data didn’t take any thought or leave room for error, and it’s one less barrier to regularly monitoring your weight, which is already enough of a hassle for most of us.

The oldest evidence for the existence of weighing scales dates to c. 2400–1800 B.C. in the Indus River valley (modern-day Pakistan). Prior to that, no banking was performed due to lack of scales. Uniform, polished stone cubes discovered in early settlements were probably used as weight-setting stones in balance scales. Although the cubes bear no markings, their weights are multiples of a common denominator. The cubes are made of many different kinds of stones with varying densities. Clearly their weight, not their size or other characteristics, was a factor in sculpting these cubes. In Egypt, scales can be traced to around 1878 B.C., but their usage probably extends much earlier. Carved stones bearing marks denoting weight and the Egyptian hieroglyphic symbol for gold have been discovered, which suggests that Egyptian merchants had been using an established system of weight measurement to catalog gold shipments and/or gold mine yields. Although no actual scales from this era have survived, many sets of weighing stones as well as murals depicting the use of balance scales suggest widespread usage.

These scales are used in the modern bakery, grocery, delicatessen, seafood, meat, produce and other perishable goods departments. Supermarket scales can print labels and receipts, mark weight/count, unit price, total price and in some cases tare. Some modern supermarket scales print an RFID tag that can be used to track the item for tampering or returns. In most cases these types of scales have a sealed calibration so that the reading on the display is correct and cannot be tampered with. In the USA the scales are certified by the National Conference on Weights and Measures’ NTEP, in South Africa by the South African Bureau of Standards and in the UK by the International Organization of Legal Metrology.

After accuracy and precision, we looked at usability elements like maximum weight limits, platform size, display size, and what it was like to actually use the scale. We looked for scales that had a comfortable, wide platform, scoring scales lower that were 12-inch squares when others’ platforms were closer to 13 inches. (Like finding out you weigh 120.0 pounds versus 119.5 pounds, even a half-inch size difference in the platform is a big deal!) Readability of the LED display is also important: Some scales had 3.5-inch blue backlit displays that made getting the weight reading somewhat more pleasant, compared with 2-inch non-backlit displays. We also preferred scales that used AAA batteries (rather than less-common-around-the-house lithium batteries) and also scales with weight limits more than 400 pounds versus those that maxed out in the 300s.

For example, after weighing myself, then weighing myself again while holding a 10-pound dumbbell, and then weighing myself yet again without the dumbbell, one of the scales rudely told me I weighed 10 pounds more than I do. Other scales would at first correctly show the additional weight difference when I was holding one of the books, but would then revert to my previous weight measurement without the book. Although some scales read my weight nearly instantly, the downside is they often seemed to be pulling from memory, whereas scales that took a few seconds to display the weight reading, such as our top picks, actually measured weight each time. I requested comment from the companies that made the offending scales, but they were not forthcoming with an explanation.

Previous studies, such as one done by Consumer Reports in 2010, have found that body-fat measurements from consumer bathroom scales aren’t all that accurate. Berkeley Wellness explains that scales that measure body fat through your feet rely on bioelectrical impedance, which sends a small (painless) electric current up your legs. Muscles contain more water than fat does, and thus conduct electricity better, so the scale calculates your body-fat percentage based on your body’s resistance to that current and other data you enter into the scale (height, age, and gender, plus the scale’s measurement of your weight). Scales with only foot electrodes—as most bathroom scales that measure body fat are—tend to underestimate body fat in people with lots of it and overestimate it in leaner people, a 2008 study published in Obesity Facts found.

Although records dating to the 1700s refer to spring scales for measuring weight, the earliest design for such a device dates to 1770 and credits Richard Salter, an early scale-maker. Spring scales came into wide usage in the United Kingdom after 1840 when R. W. Winfield developed the candlestick scale for weighing letters and packages, required after the introduction of the Uniform Penny Post. Postal workers could work more quickly with spring scales than balance scales because they could be read instantaneously and did not have to be carefully balanced with each measurement.

I read allot of the bad reviews on this and other scales, and they all seemed the same. So I bought this one cause it only does what my wife wants, weigh her. It has no,” bells or whistles” as she puts it. Next, I read the manual and sure enough, it tells you, you must first stand on, and off the scales, then back on. This calibrates the scales. If you don't do that, you get the bogus stuff that was in the bad reviews. It further says if you move the scales, you have to do the simple process over again. There are two things I find wrong, 1. It is about 5 lbs. light. 2. You have to stand on it for a few moments to lock the weight in if you need to step off to read it. I have to do this several times, so guess it is back to the manual to see what I am doing wrong. But like anything new, READ THE MANUAL FIRST. Don, retired licensed aircraft mechanic.

Weight trends over a month or so are more helpful to understanding your weight than any single day’s weight measurement. All the smart scales we considered record your weight in their mobile apps and/or websites for months, making these scales the most user-friendly way to track your weight. A handful of scales without mobile apps do show you the last few readings on the display after giving you your current weight, and we included a few of those scales in testing.

The glass platform: You either love it or you hate it. Most of the people who tried the scales for me were hesitant to use the EatSmart Precision CalPal because of its mostly glass platform. Although made of heavy, tempered glass, it looks less sturdy than the other scales because it’s mostly see-through and the glass platform is thinner than the other scales’ enclosed full bodies. (Other scales measures 2½ centimeters in height, from floor to top of the scale; the glass platform part of the Precision CalPal is about half a centimeter tall—still plenty thick but possibly off-putting for some.)

Many bathroom scales can now do much more than simply weigh people. Tracking weight history, estimating body-fat percentage, and recording weights for multiple people are the features that our experts recommended we look at in a bathroom scale—features we looked for in smart scales as well as less-expensive scales, if available.

A great range of bathroom scales are available, from the no-frills kind that just show you your weight to ones that seem to want to measure everything possible. And, as we learned from stepping on scales hundreds of times in the last couple of months, not all scales feel the same when you weigh yourself.
