When you plan to buy bed sheets for your home, the first and the foremost thing is to have the knowledge of all the bed sheet sizes available and how to choose the best fit for your particular mattress. You must know the exact size of your mattress, so that when you visit a store or an online store, you know what exactly you want to buy. There are some standard sizes such as full sheets, queen sizes, etc., however, these standard sizes also vary with different brands. Knowing the size of the bed not only helps in buying the best fitting bed sheets, but also helps in buying the right mattresses.
Some of the common bed sheet sizes include twin, king, queen, California king, etc. Flat sheets for a twin bed measure 39X75 inches whereas the same for Twin XL sheets measure 39X80 inches. That means they are five inches longer than the standard twin bed sheets. Full size bed sheets are 54X75 inches and Queen size fitted sheets measure 60X80 inches. King size is quite common and easily available at the stores. It measures 76X80 inches. California king size sheets are narrower but longer than the king size sheets. This makes them measure 72X84 inches.
It is also important to measure the pocket depth of the mattress that is the distance from the bottom edge of the mattress to the top including any pillow top or mattress topper on the mattress. This greatly helps you while buying deep pocket sheets. The standard pocket size is 7 to 9 inches, however, you can buy deep pocket sheets that have pockets ranging from 10 to 15 inches. The extra deep pocket bed sheets have a depth of 15-22 inches.
