Whether you've been upping the mileage on your daily walks, hitting the gym or working on your diet, a bathroom scale is a good way to monitor your health and fitness progress.

Types of bathroom scales – which is most accurate?
There are three main types of scales: mechanical (or analogue) scales that use springs to measure and display weight on a dial; digital scales that measure electronically and display weight digitally; and smart scales (or analyser scales) that measure by sending a safe electrical wave through the body, connecting to smartphones over Bluetooth.
Analyser scales tend to be the most accurate, offering a comprehensive breakdown of your body’s composition – some on our list can track up to 17 different metrics.
When it comes to size, a 30 x 30cm scale should be large enough for most feet without taking up too much space in your bathroom or cupboard.
What can smart scales analyse?
Smart scales use a process called bioelectrical impedance analysis to gather as much information about your body as possible. By passing a painless electrical current through your body, analyser scales measure the resistance – also known as impedance – your body gives against the current.
Different tissues such as bone, fat and muscle impede the current at different rates, which is how the scales can provide such an array of measurements, including weight, BMI, body fat, muscle mass, water percentage, bone density, resting metabolism and more.
But, it's important to remember that these values are estimates. For the most accurate measurements, you should consult a doctor, and if you’re pregnant or you have a pacemaker, you shouldn't use these features.
What is BMI?
Smart scales can usually calculate BMI, or Body Mass Index. This value is your weight divided by your height in metres squared. A BMI score is designed to help you work out roughly if you’re in a healthy weight range or not.
But this is an approximation, and it's important to note that a BMI score doesn’t distinguish between muscle, fat and bone.
Which measurements should I use?
Make sure your scales use the unit of measurement you’re most comfortable with. It’s always best to check the specs before you buy, but most on our list will give you the choice between kilograms, pounds and stone.
How we test bathroom scales
We tested over 25 sets of scales at the Good Housekeeping Institute to find the most accurate on the market. To assess their reliability when measuring weight, we placed two weights on each scale three times and recorded the results given. We also timed how quickly it took for the scales to respond to the added weight.
For smart scales, we check for consistency, taking a measurement three times within a 30-minute window to compare results.
We also test any associated apps, to see what the user experience is like, before finally scoring each set of scales for ease of use, design and product information.
