Please note: The highlighted sizes are most common. Most of the bedding available on our site can be purchased in any of these eight sizes.
Also please note that mattress depths (or height) vary widely by manufacturer. Measure the depth of your mattress before purchasing any sheets, like silk bed sheets. Standard and older mattresses average 9-12″ (23-30cm), while newer pillow-top mattresses are 14-16″ (36-41cm) deep and up. These deeper mattresses will require additional depth in fitted sheets or mattress covers.
The sizes in the table above are based on the commonly accepted standard. Be aware that bed size names vary in different countries, different cultures, and even different parts of the same country. They can actually differ in both name and size specifications from one manufacturer to another. Make sure to measure your mattress before making your purchase so that the bed linens and bed skirts you order will fit your mattress.
