Standard Mattress Sizes
Modern mattress models are commonly manufactured in the following sizes: King, California King, Queen, Full XL, Full, Twin XL, and Twin. Not all models are made in every size, though many are. Each of these mattress sizes is designed to meet a specific need, with factors like room size, how active of a sleeper you are, and whether or not you share the bed determining which size would best suit your needs.
