If you’ve ever wondered, “Will King sheets fit a California King mattress?”, you’re not alone. This is a common question among shoppers especially those upgrading their sleep setup or purchasing new bedding for the first time. The truth is, while King and California King mattresses sound similar, their dimensions differ enough to create major problems when using the wrong size sheets.
At LA Mattress Store, we often guide customers through the important distinctions between mattress sizes and how those differences affect bedding compatibility. The California King, known for its extra length, is ideal for taller sleepers or those with narrow bedrooms.
However, its narrower width means standard King sheets, which are wider and shorter, simply won’t fit properly. This mismatch can lead to bunched fabric, exposed mattress corners, and disrupted sleep.
Understanding these differences is crucial for anyone looking to maximize comfort, preserve the integrity of their mattress, and maintain a clean, tailored look in the bedroom.
In this comprehensive guide, we’ll explore the key differences between King and California King mattresses, why King sheets are not a suitable fit for California King mattresses, and what to look for when purchasing bedding that ensures a perfect fit.

Key Takeaways
- California King mattresses measure 72″ × 84″, longer and narrower than King (76″ × 80″).
- King fitted sheets do not properly fit a California King mattress they’re too short and too wide.
- Using mismatched sheets can cause bunching, poor airflow, heat trapping, and may void mattress warranty.
- The only reliable fit is using California King sheets, especially fitted ones with correct dimensions.
- Flat sheets may work across sizes but fitted sheets must match exactly.
Understanding Mattress Dimensions
Standard King (Eastern King)
- 76 inches wide × 80 inches long (≈6,080 sq in)
California King (Western King)
- 72 inches wide × 84 inches long (≈6,048 sq in)
- Preferred for taller sleepers and narrower master bedrooms common in Los Angeles layouts.
Will King Fitted Sheets Fit a California King Mattress?
No. Though widths differ by just 4″, King sheets are too wide and too short, leading to poor tuck-ins and exposed mattress ends. Most sources confirm King sheets do not properly fit Cal King mattresses.
Using King sheets on a California King may leave the bottom end exposed by about 4 inches, and excess fabric on the sides can bunch up uncomfortably.
Potential Fit Issues
- Baggy bottom sheets trap heat and reduce airflow, making sleep less comfortable and possibly causing overheating.
- Warranty concerns: ill-fitting sheets may void bed or mattress warranty per advice at LA Mattress Store blogs.
- Aesthetic drawbacks: Bunched or loose edges detract from a tidy, polished bedroom look.
Mattress Depth & Pocket Size Considerations
California King mattresses come in varying depths, often deep-profile types common in premium brands sold by LA Mattress Store. Choosing fitted sheets with matching deep pockets (13–16″) ensures proper coverage and firmness.
Flat sheets may be more forgiving across dimensions, but fitted sheets must match both width and length precisely.
Practical Advice for Proper Fit
1. Always buy California King fitted sheets labeled explicitly for 72″ × 84″ mattresses.
2. Select deep pocket sheet sets if using toppers or extra-thick mattresses.
3. Avoid trying to convert King sheets; the mismatch in length and width is unavoidable.
4. Measure your mattress height before buying to ensure sheet depth suits it.
5. Use fitted Cal King sheets from brands trusted by LA Mattress Store for optimal quality and delivery.
