General product information only, not medical advice. Always follow the bed maker’s specification sheet and your product’s labelling.
The standard hospital bed takes a 36 x 80 inch fitted sheet, and the third number, the pocket depth, has to match the mattress thickness (about 6 inches on a standard mattress). This page puts the sourced sizes in one table, shows how to read a sheet size, and lists the mix-ups that lead to sheets that do not fit.
Hospital bed sheet size chart
| Item | Width | Length | Depth / thickness | Source |
|---|---|---|---|---|
| Standard hospital bed | 36 in | 80 in | 6 in mattress (standard) | Alsco |
| Standard bed with extra cushioning | 36 in | 80 in | Standard thickness plus 1 in | Alsco |
| Fitted hospital bed sheet (Drive Medical 15030HBL) | 36 in | 80 in | 5-6 in pocket | Drive Medical |
| Wider hospital beds | 39, 42, 48 or 54 in | Check the bed’s specification | Match the mattress | Alsco |
| Extended-length beds | Check the bed’s specification | Extensions up to at least 88 in | Match the mattress | Alsco |
| Twin XL (home bedding, for comparison) | 38 in | 80 in | Not applicable | Alsco |
Check your product’s labelling and the bed’s specification sheet before ordering. The sizes above are the figures the named manufacturer and linen-service sources state, and they are not a universal standard.
How to read a hospital bed sheet size
A fitted sheet size is written as width x length x depth. The Drive Medical hospital bed linen kit lists its fitted sheet as 36 in x 80 in x 5-6 in, so the first two numbers describe the mattress surface and the last describes how deep the sheet pocket reaches. The kit contains two fitted sheets, made from a cotton and polyester blend, and is listed as suitable for most standard manual, semi-electric and full electric beds.
The depth is the number that most often goes wrong. Compare the pocket depth with the mattress thickness, not with the bed frame. Alsco notes that a fitted sheet that is too small will not fit and one that is too large will bunch.
How to measure for sheets
- Read the width and length from the bed’s specification sheet or label, or measure the mattress surface.
- Measure the mattress thickness, including any added cushioning layer. Alsco gives 6 in as the standard mattress thickness and notes that some mattresses add an additional inch of cushioning.
- Compare all three numbers with the sheet’s labelled width x length x depth.
- For a fitted sheet, choose a pocket depth that covers the measured thickness.
Equivalence notes: twin XL, wider beds and extensions
Twin XL versus hospital bed
Alsco describes the average hospital bed as close to twin XL (38 x 80 in). Because of the 2 in difference in width, check the labelled size rather than assuming a home twin XL fitted sheet suits a 36 in hospital mattress.
Wider and longer beds
Alsco lists hospital beds in 39, 42, 48 and 54 in widths, and lengths that extend to at least 88 in. For a bariatric bed, a width quoted in a specification may be measured between the siderails rather than across the whole bed. The bariatric bed guide shows one model offering 36, 42 and 48 in inside the siderails, with a wider overall outside width. Use the mattress dimension, not the overall bed width, when sizing sheets.
Sheet types
Alsco names three sheet types for a hospital bed. Fitted sheets need the most precise sizing because they fit snugly around the mattress. Draw sheets are used by staff when a patient needs to be moved; Alsco says they need not cover the whole bed and that their sizing varies. Alsco describes a flat sheet as typically an extra layer between a person and the mattress cover. The linen cart guide covers how clean linen is stored and moved, and the hospital blanket guide covers the layer that goes over the sheets.
Common mix-ups
- Treating a fitted sheet as a mattress cover. CDC states that a linen sheet placed on the mattress is not considered a mattress cover. See the mattress cover guide for the difference.
- Using twin XL bedding. Twin XL is 38 in wide against the 36 in standard hospital bed.
- Ignoring pocket depth. Width and length can match while the depth does not.
- Using a home-bed size. Home adjustable bed sizes are covered separately in the adjustable bed dimensions guide; confirm which bed you are sizing for.
- Reading overall bed width as mattress width. Siderail and frame measurements are larger than the mattress surface.
Frequently asked questions
What size sheets fit a hospital bed?
For a standard hospital bed, 36 inches wide by 80 inches long, with a pocket depth that covers a mattress of about 6 inches. Drive Medical lists a fitted hospital bed sheet of 36 x 80 x 5-6 in. Wider or longer beds need sheets sized to their own mattress.
Are hospital bed sheets the same as twin XL?
No. Alsco describes the average hospital bed as close to twin XL, which is 38 x 80 in, but a standard hospital bed is 36 x 80 in, so the widths differ by 2 inches.
How wide are hospital beds?
Standard hospital beds are 36 inches wide. Alsco also lists 39, 42, 48 and 54 in wide beds.
