Mattress Size vs. Sheet Size: Key Differences
It's important to note that the king size bedsheet size in cm is not the same as the mattress size. The mattress itself is typically 76″ × 80″ (193 × 203 cm). The fitted sheet is slightly smaller (72″ × 78″) to ensure a snug fit around the corners, while the flat sheet is larger to allow for tucking.
⚠️ Common Mistake to Avoid
Many buyers confuse the king mattress size (193 × 203 cm) with the fitted sheet size (183 × 198 cm). Always check the product label for the fitted sheet dimensions to ensure it matches your mattress depth.
California King vs. Standard King: What's the Difference?
If you have a California King bed, the sheet sizes are different. A California King mattress is longer and narrower: 72″ × 84″ (183 × 213 cm). The fitted sheet for a California King is typically 72″ × 84″, while the flat sheet is 102″ × 108″.

Fitted Sheet Depth: Why It Matters
Pocket depth is one of the most critical factors when buying a fitted sheet. Standard sheets have a pocket depth of 35–40 cm (14–16 inches). However, if you have a pillow-top or an extra-thick mattress, you may need a "deep pocket" sheet with a depth of 45–50 cm (18–20 inches).
Always measure your mattress thickness before purchasing. For more tips on choosing the right bedding, explore our Bedding & Linens guide.
Best Materials for King Size Sheets
The material you choose affects comfort, durability, and temperature regulation. Here are the most popular options:
- Cotton (Egyptian or Pima): Soft, breathable, and durable. Ideal for year-round use. Prices range from $150–$300 for a quality set.
- Linen: Highly breathable, moisture-wicking, and gets softer with each wash. Expect to pay $250–$500+.
- Bamboo: Eco-friendly, silky soft, and naturally hypoallergenic. Prices around $180–$350.
- Microfiber: Affordable, wrinkle-resistant, and easy to care for. Budget-friendly at $80–$150.
If you're looking for a complete bedding upgrade, consider pairing your new sheets with a mattress topper for added comfort.
Thread Count: Does It Really Matter?
Thread count refers to the number of threads woven into one square inch of fabric. While a higher thread count often indicates better quality, it's not the only factor. For king size sheets, aim for a thread count between 300 and 600 for a balance of softness and durability.
Sheets with a thread count above 800 may feel stiff and are often less durable. Always check the fabric type alongside the thread count.

How to Measure Your King Mattress for the Perfect Fit
Follow these simple steps to ensure you buy the correct king size bedsheet size in cm:
- Measure the length and width: Use a tape measure to confirm your mattress is 193 × 203 cm (76″ × 80″).
- Check the thickness: Measure from the bottom of the mattress to the top edge. Add 2–3 cm for the mattress protector.
- Consider the topper: If you use a topper, include its height in the total thickness.
- Compare with the sheet's pocket depth: Ensure the fitted sheet's pocket depth is equal to or greater than your mattress thickness.
