The different kinds of scales are:
Digital electronic - these use batteries and show your weight in digital precision. You can set them to weigh you in pounds, kilograms or stones. Some have enhanced functions such as memory programs which can remember your previous weight.
Traditional mechanical scales - spring-based mechanical scales which show your weight on an analogue dial. 'Doctor' style ones (below) show the whole dial rather than just a section.
What to look for:
Easy to read display
You need to be able to clearly see the display from a standing position. On digital scales, look for large and back-lit displays.
If buying mechanical scales choose ones with large lettering so you can get a precise reading.
Ease of use
Make sure they are easy to switch on and off and straightforward to set up. Is it easy to change batteries, switch to different weight formats, reset etc?
Mechanical scales should be easy to reset as you may need to do this regularly to keep them accurate.
If you don't want your scales on permanent view, choose a light-weight pair you can store easily or a set with smaller dimensions that won't take up too much floor space.
Many digital scales have memory functions that remember your previous weight, weight targets etc.
Body fat monitors
If you want your scales to do more than just weigh you, look for ones that can analyse your body fat and Body Mass index and read your water and bone mass.
Wi-Fi enabled bathroom scales can send your weight to your laptop, computer or smartphone so you can track everything online.
How to weigh yourself:
- Weigh yourself at the same time of the day
- Remove your clothes and shoes or wear light clothes. If wearing clothes make sure you are wearing the same items each time you weigh yourself.
- Put the scales on a hard, flat surface like your bathroom floor. Don't put them on carpeted floor as this will give you an inaccurate reading.
