California King vs King Sheets
Cal King fitted sheets are 72x84". King fitted sheets are 76x80". They do NOT fit each other. Flat sheets and comforters are usually interchangeable.
Sheet Size Comparison
| Item | Cal King | King | Interchangeable? |
|---|---|---|---|
| Flat sheet | 108" x 102" | 108" x 102" | Yes (same size) |
| Fitted sheet | 72" x 84" x 14-18" | 76" x 80" x 14-18" | No |
| Comforter/Duvet | 104" x 98" | 106" x 92" | Usually (slight size difference) |
| Duvet cover | 104" x 98" | 106" x 92" | Usually |
| Mattress pad | 72" x 84" | 76" x 80" | No |
| Bed skirt | 72" x 84" | 76" x 80" | No |
The most common mistake:
Buying King fitted sheets for a Cal King mattress. They will be too wide (4" extra) and too short (4" missing). The corners will not stay tucked and the sheet will bunch up. Always check the label for "California King" specifically.
Finding Cal King Sheets
Cal King sheets are less common in stores. Most retailers carry them online but not in-store. Amazon, Target, and Brooklinen all stock Cal King sizes. Look for "Cal King" or "California King" on the label, not just "King."
Expect to pay 5-15% more for Cal King sheets compared to standard King due to lower production volume.
