My view of bathroom scales has shifted significantly since testing dozens of them for this review. I once associated them with keeping track of weight alone, but that’s far from accurate. Nowadays, the best bathroom scales are hi-tech devices able to track trends in body composition, fat loss, muscle mass and even nerve health and heart rate, placing them in the same sphere as fitness trackers, smart rings and smart watches.
Most modern smart scales use something called bioelectrical impedance analysis (BIA), a painless electrical current that’s sent through your body to estimate your fat, muscle and water levels. It’s not a medical-grade reading, but it’s really good at helping you spot patterns over time. Jonathan Wells, professor of anthropology and paediatric nutrition at University College London, tells me that while you shouldn’t expect BIA to give you an accurate value on day one, it will deliver a good indication as to whether you’re gaining or losing muscle and fat. “The real value comes from seeing the direction of travel,” he says.
Over the course of a year, I’ve been hopping on and off a range of smart and digital bathroom scales, tracking my metrics week by week and assessing the depth and accuracy of information provided. Eufy’s P2 pro smart scale is my top pick, owing to its balance of features and value (its sleek design also weighed heavily in its favour). If you’re looking for especially in-depth data analysis, then I’d recommend the Withings body comp scale, as it displays easy-to-follow trends and detailed graphs, but keep scrolling for my full list of top performers.

How I tested
I’ve spent several months testing a mix of smart and digital bathroom scales, using each one regularly to track body composition metrics and compare week-to-week trends. I do CrossFit most days, occasionally intermittent fast and regularly monitor my weight and muscle mass as part of my routine, so I was particularly interested in finding the best scales for tracking my progress.
I’ve looked at how consistent the readings were across multiple weigh-ins, how intuitive the setup felt and how good the companion app was for monitoring changes over time.
While the BIA-based smart bathroom scales in this list are safe for most people, manufacturers advise against using them if you’re pregnant or have a pacemaker.
