Bedding set usually includes quilts, pillows, bedspreads, comforter, blankets, and coverlets.
Quilts come in a variety of shapes and sizes, so there isn’t a one size fits all. However, you can use these sizes as a general guide:

Note: If you own one of the unusual sizes mentioned above, we would suggest King/Cal King duvet covers and duvet inserts for all of them, queen flat sheets for the Olympic Queen, and King/Cal King flat sheets for the SF and Grand King. Fitted sheets are more challenging because they should match the mattress dimensions. A Cal King fitted sheet will fit relatively well on an Olympic Queen, but for the outsized kings, you’ll need to contact the companies that make them for appropriately fitted sheets.

In addition to the size, it’s important to understand the type of filling in a quilt. We normally produce the quilts with fillings of Microfiber / Cotton / Silk fiber.
