How to Choose the Right Bed Sheet Size

A comfortable bed starts with sheets that fit properly. Before choosing a colour or pattern, check your mattress measurements and whether you need a flat sheet or a fitted sheet. Size names such as “King” and “Super King” can vary between manufacturers, so always compare the actual dimensions.

Measure Your Mattress First

Use a measuring tape to record three measurements:

• Width: Measure across the mattress from side to side.
• Length: Measure from the head of the mattress to the foot.
• Depth: Measure the mattress thickness, including any topper used underneath the sheet.

Write these measurements in centimetres and keep them nearby when shopping.

Choosing a Flat Sheet

A flat sheet needs to be larger than your mattress so that it can hang over the sides and tuck underneath.

For example, a sheet measuring 250 × 270 cm placed on a mattress measuring 180 × 200 cm leaves approximately 35 cm on each side when centred. Some of that allowance will cover the mattress depth, with the remainder available for tucking.

For a deeper mattress or a more generous tucked finish, you may need a larger sheet. Check both dimensions rather than relying only on the size label.

Choosing a Fitted Sheet

A fitted sheet should match your mattress width and length. Its pocket depth must also accommodate the mattress and any topper.

A sheet with pockets that are too shallow may pull away from the corners. One that is too large can leave loose fabric on the sleeping surface. Check the manufacturer’s stated mattress dimensions and depth range before ordering.

Check What the Set Includes

A bed sheet set may contain a flat sheet, a fitted sheet, pillowcases or a combination of these. Read the contents carefully: a “bed sheet set” does not automatically include both sheet types or a duvet cover.

Also compare the pillowcase measurements with your pillows.

Make Your Final Check

Before buying, confirm the sheet type, dimensions, fabric and pack contents. For custom bedding, double-check your measurements before production begins.
