A bedsheet can look generous in its packaging and still leave you struggling to tuck it under your mattress. The problem often becomes clear when one corner comes loose as you pull another into place. Getting the fit right starts with three measurements: mattress width, length and depth. This guide explains the sizes you may find in India, how to compare them, and what to check before placing your order.
What Size Should You Buy for an Indian King Bed?

A common Indian king mattress measures 72 inches wide and 78 inches long, or approximately 183 by 198 centimetres. However, your mattress may have different dimensions, particularly if it was made to order.
When buying king-size bedsheets, check whether the measurements describe a flat sheet or the mattress that a fitted sheet accommodates. These numbers serve different purposes.
A flat sheet measuring 108 by 108 inches is one widely available option. It measures approximately 274 by 274 centimetres and provides fabric beyond the mattress edges for covering the sides and tucking underneath.
| Item | Example dimensions | What the numbers describe |
| King mattress | 72 by 78 inches. | These describe the sleeping surface. |
| Flat bedsheet | 108 by 108 inches. | These describe the entire sheet. |
| Fitted bedsheet | 72 by 78 inches, with depth specified separately. | These describe the intended mattress fit. |
Treat these as examples, since product sizes vary between brands.
Measure Your Mattress in Three Simple Steps
Remove your existing sheet before measuring. Use a measuring tape and record all dimensions in the same unit.
Measure the Width
Run the tape across the mattress from one side to the other. Keep it straight across the top surface. Avoid including the bed frame, wooden borders or headboard.
Measure the Length
Measure from the head end to the foot end. Do not assume that every mattress on a six-foot-wide bed has the same length.
Measure the Total Depth
Measure vertically from the mattress base to the top of your sleeping surface. Include any topper or padded cover that will sit beneath the sheet. Avoid pressing down on soft layers while measuring.
For example, an eight-inch mattress with a two-inch topper needs a fitted sheet that accommodates their combined ten-inch depth.
If your bed uses two separate mattresses, measure their combined width and check whether they move independently. One fitted sheet can cover both when the dimensions match, but separate sheets may be more practical if either mattress needs to be lifted or adjusted on its own.
Calculate How Much Flat Sheet Fabric You Need
The extra fabric beyond each mattress edge must cover its depth before any material reaches underneath. This explains why a sheet that covers the top can still be too small for tucking.
Use these calculations as a starting point:
- Required width equals mattress width plus twice its depth, plus your total allowance for tucking underneath both sides.
- Required length equals mattress length plus twice its depth, plus your total allowance for tucking underneath both ends.
Suppose your mattress measures 72 by 78 inches and is eight inches deep. You want four inches of fabric tucked underneath each edge.
Your calculated sheet size would be 96 inches wide and 102 inches long. A 108 by 108 inch sheet exceeds those dimensions, giving you some additional fabric to arrange.
This example assumes you tuck all four edges. If you leave the head end untucked, your preferred arrangement may need less length. Printed borders and pattern direction may also affect which way you spread a rectangular sheet.
Check Pocket Depth When Buying Fitted Sheets
Fitted sheets have shaped corners and elastic that hold the fabric around the mattress. Their pocket depth indicates how much mattress thickness the corners can accommodate.
Read the seller’s stated maximum mattress depth rather than judging by photographs. Some listings provide the fabric pocket measurement; others state the mattress thickness the sheet fits. Ask for clarification if this is unclear.
The length and width must also match your mattress. A deeper pocket cannot compensate for a sheet that is too narrow. Likewise, buying a much wider fitted sheet can leave loose fabric across the sleeping surface.
Be Careful With Overseas Size Labels
The word king does not represent one worldwide measurement. An imported sheet labelled king may be designed for a mattress with different proportions from yours.
For king-size bedsheets sold through international listings, compare actual measurements and the supported mattress size. Convert units before comparing. One inch equals 2.54 centimetres, so mixing inches and centimetres can easily lead to an incorrect order.
Recognise the Signs of a Poor Fit
A properly sized sheet should lie smoothly without requiring you to force the corners into position.
- Corners lifting immediately can indicate insufficient pocket depth or incorrect mattress dimensions.
- Excess fabric gathering beneath you can suggest an oversized fitted sheet.
- Flat sheet edges that barely reach the mattress base leave little material for tucking.
- A sheet that slips despite adequate dimensions may have worn elastic or need more secure tucking.
Check the underlying cause before replacing the sheet with a larger size.
Allow for Washing and Everyday Use
Cotton can shrink, although the amount depends on the fabric, finishing and washing conditions. Check whether the seller provides shrinkage information or describes the sheet as preshrunk.
Follow the care label, especially its washing temperature and drying instructions. Before washing a new purchase, check the return policy and confirm the supplied size. Washing may affect your ability to return it.
Make Your Final Choice With Confidence
Keep your mattress measurements on your phone so you can check product details while shopping. Confirm the sheet type, dimensions, depth allowance and pack contents. Pillow covers should be checked separately because a king label does not establish their size.
Once those details match, you can enjoy choosing colours and prints that suit your bedroom. A few minutes with a measuring tape can make changing your bedding much easier.
