StandardsVarious standard bed sizes have been developed and emerged over the years. Unfortunately they're not completely "standard"! Choosing and buying the best size for your bedroom can be confusing, as can buying the right sheets and other bedding for your chosen size of mattress. This can be especially important if you plan to buy bed linen etc online from another country - standard sizes are interpreted very differently in the US and the UK.
VariationsBed size standards vary around the world. Not only are the names of the standard sizes sometimes different but even beds and mattresses with the same name can have different measurements in different countries. For example a standard British King is smaller than a standard American Queen! Don't rely on the name alone when buying, always check the exact dimensions and make sure you know what you're getting.
Even within a single country different manufacturers interpret the "standard" bed sizes differently. Some might shave a couple of inches off to reduce cost, others add a little for comfort. A few inches can make a lot of difference in bed.
Beds are usually labelled according to the dimensions of the mattress - the actual measurements of the bed itself might be a little wider and/or longer. Check this when planning you bedroom furniture layout, don't just rely on the mattress measurement. Obviously bed linen will be significantly larger than the standard mattress size and again some manufacturers are more generous than others.
Measurement TablesThe tables below give common interpretations of the "standard" bed sizes. Use these size charts as a guideline, but always check the exact dimensions before you buy. At the end of the day "standard" is best considered as a starting point - a guide rather than a hard and fast rule.

The range of standard British bed sizes is smaller than that of the US - and British beds themselves usually have smaller dimensions than their US version with the same name.
