This section is emphatically not science, but there's not enough to merit a page of its own and I couldn't think where else to put it.
I feel there's some potential for controversy here, as there doesn't appear to be any official ruling. The following came from the website of The Oak Bed Store (a UK online bed retailer). Wikipedia (needless to say) has a comprehensive page on the subject, giving sizes from around the world. Wikipedia takes the view that UK retailers are now obliged to sell in metric sizes, and gives the nearest Imperial equivalents (in inches) to the metric sizes. It refers to the Imperial sizes given here as "previous" sizes. In my experience, if you're ever asked about bed sizes in a quiz, these are the ones that are used; so I've stuck with what Wikipedia calls the "previous" Imperial sizes.
You may notice that while the Imperial and metric measures of width are approximately equivalent, the lengths are even less exactly so.
I haven't bothered to hide the answers, as I can't really imagine anyone wanting to test themselves on this.
