Choosing what size mattress to buy isn’t easy, especially considering the array of choices available. This chart lists common mattress sizes (in inches); however, keep in mind that sometimes mattress manufacturers reduce the size an inch or two. This is quite common, as it allows your comforter and sheets to go in between the footboard and the mattress.
When you’re deciding which size to buy, take into consideration your height and the size of your bedroom (record the dimensions before your shop)! Some additional factors to consider include whether or not you sleep with a spouse or partner, and if children and pets share your bed.
