Standard Mattress Sizes Explained

Before you buy a mattress it is crucial you buy the right size. Standard mattress sizes vary between Europe and North America so be sure to get the correct size according to your geographical location.

Perhaps the first thing to consider is the size of any existing bedding (sheets, bed covers or duvets etc) you have. In Europe stores such as Ikea stock US sizes so it can be confusing what size you need to go for. Measure twice and order once! Not only are the sizes different on different sides of the Atlantic but also the naming conventions used to describer mattress sizes.

Below is a table showing standard mattress sizes used in both Europe and North America. Use it as a guide to help you ensure that the mattress you choose matches both your bed frame and existing bedding. The table is based on average standard of mattress sizes. Due to different production methods and materials used mattresses can differ by up to two inches in width/length so expect some slight variations.

Standard Mattress Sizes

When bed frames are advertised they are usually described in their sales literature according to their mattress size. When measuring the space for your new bed (assuming you are buying a new frame as well as a new mattress) allow extra width over and above the size of mattress chosen to allow for your beds frame.

A typical bed frame requires an extra 20-30cm of width though they all vary so be sure to measure carefully before ordering. If you have a tight space to put the bed (say between two fitted bedside cabinets) you’ll need to ensure you measure the width to include the frame size, not just the mattress.
