From Good Housekeeping
Before buying a new mattress, there are many factors to consider, such as material, firmness, and cost — but the first decision you’ll always have to make is size. Most mattresses are available in Twin, Full, Queen, King, and California King sizes with some stores offering crib and Twin XL sizes too.
The Good Housekeeping Institute Textiles Lab consists of bedding experts who evaluate mattresses, sheets, and pillows for your perfect bed. Our pros explain the differences between standard mattress sizes to make it easier than ever to find your dream bed. While these are the standard dimensions, sometimes there will be slight differences brand to brand. It’s always best to confirm the specific dimensions of the mattress before buying.
