Traditional Mattress Sizes
If you are ordering a mattress for your home, it is helpful to know the standard measurements available in most mattress retailers. If your measurements are not within a 1.5 inch tolerance of these traditional sizes, you may need to order a custom size. Please see our Mattress Custom Services page for a list of commonly ordered custom sizes and more details. The traditional mattress sizes are as follows:
Twin/Single: 38” x 74” Twin XL: 38” x 80” Full/Double: 53” x 74” Queen: 60” x 80” Eastern King: 76” x 80” California King: 72” x 84”.
