Mattress Size vs Bed Frame Size When buying a new bed, you’ll want to ensure it fits in your room comfortably, so you’ll need to know which bed frames tend to have larger dimensions. Most often, these are metal and wooden bed frames as the mattress sits within the frame rather than on top of a base. However, we do advise you to always check the dimensions on any product before making your purchase.
Bed frame size according to style The dimensions of your bed will differ depending on which style of bed frame you choose:
Divan beds without a headboard will have the same dimensions as your mattress as it will sit flush on top of the divan base.
Wooden bed frames are usually a few centimetres bigger than your mattress around each side.
Upholstered bed frame dimensions differ hugely depending on whether they have a sleigh shape, the amount of detail and the fabric.
Always check the dimensions of the bed before purchasing to ensure it fits in the room with enough space to move around the sides.
