Although the above-given dimensions are the standard sizes in different parts of the world, there could still be a bit of discrepancy in the actual size of some bed mattresses depending on the manufacturer.
However, you may use the above information as a reference point for your bed sizes to give you an idea of how much space you need to reserve for your bed frame and mattress inside the bedroom as well as help you select the appropriate bed sheets and comforters for your type of bed mattress.
To get the right sizes for your flat sheets and fitted sheets, you should check the label for the specific mattress type, i.e. Twin, Double, King or Queen; as well as the exact dimensions, whether in inches or centimeters.
Incidentally, if you are looking into buying a crib mattress, the US standard size for this is 27 inches by 50 inches. There are however, other crib sizes available so it’s best to take your measuring tape with you when determining crib sizes for the nursery.
