Bathroom Scale Review

Comparing accuracy and ease of use of bathroom scales

Today's bathroom scales are available in two main varieties -- digital and mechanical (also known as analog or dial) scales. Mechanical scales, which possess a more delicate internal framework of small springs and pieces, display readings with a mechanical needle, but their more fragile nature means they can wear out faster, plus their tinier print typically makes them more difficult to read. Analog scales also measure weight in larger increments than digital scales, a trait which can make them less accurate. In fact, several comparison reviews we found reflect this finding. Consequently, experts say most digital scales are more accurate than analog scales.

Bells and whistles on digital models can run the gamut from voice-activated readouts to multi-user memory. Additionally, we found Wi-Fi connectivity to be a growing trend. These high-tech digital scales send weight information wirelessly to a computer or mobile phone, allowing users to effortlessly track their weight-loss progress.

Some digital scales can also monitor body fat. Body-fat scales send small, harmless electrical pulses through a user's body in an attempt to gauge body weight/density. However, body-fat scales have been found to be inaccurate by experts, since readings can be thrown off by a number of inconsequential factors including a person's level of hydration, a full bladder or foot calluses. For these reasons, many professional sources, including ConsumerReports.org, no longer test or recommend body-fat scales.

One last type, professional mechanical scales, (similar in look and style to those found in gyms and doctors' offices), are more accurate than analog scales designed for home use. That's because professional mechanical scales employ a sturdier, heavy-duty lever arm to calculate weight, rather than the delicate springs typically used in stand-on analog scales. Professional mechanical scales also possess larger weight limits. Many models can accommodate users up to 500 pounds. Full-size mechanical scales can take up a lot of room and can be quite expensive.

The best reviews of bathroom scales come from ConsumerReports.org and Good Housekeeping, which test 11 and 20 scales, respectively. Each organization clearly lists their testing criteria, but both have their downsides. ConsumerReports.org rates each scale on accuracy and consistency, but editors do not comment on any of the individual scales or list pros and cons. On the other hand, Good Housekeeping includes a paragraph of analysis for each bathroom scale, but the individual scales do not receive a numerical rating. Taken together, however, these sources provide a good overview of which bathroom scales are the most accurate. Prevention magazine, Real Simple and Women's Health magazines also review bathroom scales, but their testing processes are not as detailed. We also examined user reviews, where owners provide good information on consistency and durability of bathroom scales. Amazon.com is the best spot for user feedback, with some bathroom scales attracting hundreds of individual reviews. Walmart.com and Buzzillions.com also have some bathroom-scale reviews.
