Before buying a bed, one of the key considerations you have to make first is size. Is it going to fit in your bedroom? Will it meet your specific height requirements? The variation of bed sizes around the world on offer is exceptional, it is more or less guaranteed that there will be a bed size out there to suit most of your needs and requirements. If you happen to be limited on space, with a loft or attic bedroom that has a sloping ceiling or have space at your fingertips with a large master bedroom, there is sure to be a bed size out there that can offer you a solution. Dimensions and bed frame names vary significantly around the world, with most countries having their own standards and terminology, especially America.

The size of a bed frame is influential, it is the be all and end all of your bed selecting journey, if mistakes are made at this stage it could hinder your chances of a perfect bed frame. Ensure that you follow the guides clearly, and you measure your required space specifically and you will have no problems in selecting the right bed size to suit you. Here at Guide Me To Bed, our expert knowledge has enabled us to collate a chart of bed frame sizes for the UK and for the USA as seen below, in order to help our consumers in these global areas to select the right bed size to meet their exact needs.


Different Options Available

If it is a loft or attic space that you find yourself working with but you really want a king size bed frame, then maybe a Space Saver or Platform Bed is the option that you should favour. Space Saver beds sit very low to the ground, and the main difference between them and a standard height bed is that they take a lot less floor space, as the bed frame itself is a lot smaller than it would necessarily be with a standard height bed. This design gives the mattress a floating effect, and no legs sit at the foot of the bed, meaning that vital room is saved and you can get the bed size that you want.

There is now a new design called the Zip and Link Mattress, this incorporates two single mattresses that have a zip system down one side enabling them to zip and link together to form a larger sized mattress. This new design makes it a lot easier to maneuver mattresses into awkward spaces, like up into loft or attic spaces that have an awkward entrance or stairwell. Also in modern times, many different mattresses can be brought rolled up and compressed to make them remarkably easier to maneuver, and once in their designated area and all packaging is removed, the compressed air will be released and the mattress will begin to return to its normal form.

Some wooden bed frames now rather than the mattress being inset into the bed frame, have the mattress sit on top of the wooden frame to increase the space you have in your bedroom and stop you from bumping into the frame.
