Our bed size calculator, or mattress size calculator, is here to help you when buying a bed. If you're asking yourself, "How do I calculate bed size?" then check out the bed size guide below, which helps you find the ideal mattress length based on your height and region.

Bed size guide

Choosing the right bed size is important for good sleep and comfort. If you’re wondering how to calculate bed size, our bed size calculator is here to help!

This simple tool gives you a clear answer based on your height. The general rule for finding a comfortable bed length is to add 20 cm (about 8 inches) to your height, and this gives you enough space to stretch out without feeling like a Bigfoot.

Our bed size guide uses this method (adding at least 20 cm or 8 inches to your height) to suggest both a minimum and a comfortable bed length for you. After getting your result, you can check which standard bed sizes match that length. Keep in mind that bed width is more personal — it depends on how much you move in your sleep, your body size, and how much room you have in your bedroom.
