Choosing the right size bed sheet is essential for a comfortable and tidy bed. A sheet that's too small will slip off during the night, and one that's too big can look messy and uncomfortable. To help you pick the perfect fit, we’ve created this simple guide based on your mattress size — with measurements in both centimeters (cm) and inches (in).
1. Measure Your Mattress
Before buying new sheets, measure your mattress carefully. You need to know three dimensions:
-
Length (head to foot)
-
Width (side to side)
-
Depth/Height (from the base to the top)
Use a measuring tape and note down the numbers in centimeters and inches if needed. Remember, thicker mattresses (especially pillow-top or memory foam ones) might need deeper fitted sheets.
2. Common Mattress Sizes and Sheet Sizes
Here’s a quick reference chart for standard mattress sizes and the matching sheet sizes:
Mattress Size | Dimensions (cm) | Dimensions (inches) | Sheet Size to Choose |
---|---|---|---|
Single | 90 x 190 cm | 35" x 75" | Single Sheet |
Twin XL | 90 x 200 cm | 35" x 79" | Twin XL Sheet |
Full / Double | 140 x 200 cm | 55" x 79" | Full/Double Sheet |
Queen | 160 x 200 cm | 63" x 79" | Queen Sheet |
King | 180 x 200 cm | 71" x 79" | King Sheet |
Super King | 200 x 200 cm | 79" x 79" | Super King Sheet |
Tip: Always check your mattress depth. Standard sheets usually fit up to 30 cm (12") deep mattresses. For thicker mattresses, look for deep pocket sheets.
