Bed Sheet Sizes: Fitted Sheet, Flat Sheet and Pillowcase Dimensions
Fitted and flat sheet dimensions for every US bed in inches and centimeters, how to read pocket depth, which sheets cross over between sizes, and what to buy for European and UK beds.
A fitted sheet matches the mattress: a queen fitted sheet is 60 × 80 in (152 × 203 cm) with a pocket for the mattress depth, usually 14 in (36 cm). Flat sheets are larger so they hang over the sides: a queen flat sheet is about 90 × 102 in (229 × 259 cm), a king flat is 108 × 102 in and a twin flat is 66 × 96 in.

Bed sheet size chart
A sheet set holds two different sizes. The fitted sheet is cut to the mattress plus a pocket, and the flat sheet is cut wider and longer so it can be tucked in. Fitted dimensions are fixed by the mattress. Flat sheet sizes vary by an inch or two between brands; the figures below are the most common.
| Bed size | Fitted sheet (in) | Fitted sheet (cm) | Flat sheet (in) | Flat sheet (cm) |
|---|---|---|---|---|
| Twin | 38 × 75 | 97 × 191 | 66 × 96 | 168 × 244 |
| Twin XL | 38 × 80 | 97 × 203 | 66 × 102 | 168 × 259 |
| Full (double) | 54 × 75 | 137 × 191 | 81 × 96 | 206 × 244 |
| Queen | 60 × 80 | 152 × 203 | 90 × 102 | 229 × 259 |
| King | 76 × 80 | 193 × 203 | 108 × 102 | 274 × 259 |
| California king | 72 × 84 | 183 × 213 | 102 × 110 | 259 × 279 |
Fitted sheets are labeled with three numbers: width, length and pocket depth. A queen sheet listed as 60 × 80 × 14 in fits a 60 × 80 in mattress up to about 12 in thick. Mattress widths and lengths for every size, including European ones, are on the mattress size chart.
Fitted sheet pocket depth
The pocket is the height of the sheet's side wall. It has to cover the mattress side, plus any topper, and still wrap 1 to 2 in under the bottom edge. Too shallow, and the corners pull off overnight. Too deep, and the sheet wrinkles across the top.
| Label | Fits a mattress (plus topper) of | |
|---|---|---|
| Standard | 12–14 in (30–36 cm) | Up to about 12 in (30 cm) |
| Deep pocket | 15–18 in (38–46 cm) | 13–16 in (33–41 cm) |
| Extra-deep pocket | 19–24 in (48–61 cm) | 17–22 in (43–56 cm) |
"Deep pocket" is a marketing label, not a measurement. One brand's deep pocket is 15 in and another's is 18 in, so always buy by the number. Typical mattress thicknesses by type are listed in the mattress depth guide.
- Measure the mattress side from the bottom seam to the top, at the edge, not the center.
- Add the topper and pad. A 3-in topper turns a 12-in mattress into a 15-in stack.
- Add 1 to 2 in for the elastic to grip underneath.
- Buy the next pocket size up if you land between two. A 16-in result means a 16 to 18-in pocket.
Cotton and linen sheets that are not pre-shrunk can lose a few percent of their length in the first hot wash and dryer cycle. On an 80-in sheet, 3% is 2.4 in. If a new fitted sheet is barely long enough, wash it cool and dry it on low.
Flat sheet sizes and overhang
A flat sheet sits between you and the blanket, so it only needs to reach down the mattress sides far enough to tuck in. Subtract the mattress width from the sheet width and halve it to get the drop on each side.
| Size | Flat sheet | Drop each side | Extra length |
|---|---|---|---|
| Twin | 66 × 96 in | 14 in (36 cm) | 21 in (53 cm) |
| Twin XL | 66 × 102 in | 14 in (36 cm) | 22 in (56 cm) |
| Full | 81 × 96 in | 13.5 in (34 cm) | 21 in (53 cm) |
| Queen | 90 × 102 in | 15 in (38 cm) | 22 in (56 cm) |
| King | 108 × 102 in | 16 in (41 cm) | 22 in (56 cm) |
| California king | 102 × 110 in | 15 in (38 cm) | 26 in (66 cm) |
The extra length is split between a fold-over at the top and a tuck at the foot. On a 15-in deep mattress, a standard queen flat sheet barely reaches the bottom of the sides and leaves nothing to tuck. Buy a flat sheet one size up (a king flat on a queen gives 24 in of drop) or one sold for deep mattresses.
Sizes that do and do not cross over
People often try sheets from the next size over. Elastic forgives about an inch, not more.
| Sheet → mattress | Difference | Result |
|---|---|---|
| Twin → twin XL | 5 in too short | Will not stay on |
| Twin XL → twin | 5 in too long | Works, bunches at the foot |
| Twin XL → full | 16 in too narrow | Will not fit |
| Full → queen | 6 in narrow, 5 in short | Will not fit |
| Queen → full | 6 in wide, 5 in long | Loose and wrinkled |
| King → Cal king | 4 in wide, 4 in short | Corners slip off |
| Two twin XL → split king | Exact | The intended setup |
A split king (two 38 × 80 in mattresses on separate adjustable bases) uses two twin XL fitted sheets and one king flat sheet. A "split-top" king, where only the head section is divided, needs a special fitted sheet with a matching slit.
Sheet sizes for UK and European beds
Fitted sheets abroad are sold by the mattress size in centimeters, so a 160 × 200 fitted sheet fits a 160 × 200 mattress. US sheets do not map neatly onto these beds.
| Mattress | In inches | Closest US fitted sheet | Fit |
|---|---|---|---|
| 90 × 200 cm (EU single) | 35.4 × 78.7 | Twin XL (38 × 80) | Loose by 2.6 in width |
| 135 × 190 cm (UK double) | 53.1 × 74.8 | Full (54 × 75) | Good |
| 140 × 200 cm (EU double) | 55.1 × 78.7 | None; full is 3.7 in short | Buy metric |
| 150 × 200 cm (UK king) | 59.1 × 78.7 | Queen (60 × 80) | Good |
| 160 × 200 cm (EU queen) | 63.0 × 78.7 | Queen is 3 in narrow | Tight; buy metric |
| 180 × 200 cm (EU king, UK super king) | 70.9 × 78.7 | Cal king (72 × 84) | Loose at the foot |
For the flat sheet on a 160 × 200 cm bed, look for about 240 × 260 cm or larger. A US queen flat sheet (229 × 259 cm) drops only about 34 cm on each side, which barely covers a 30 cm mattress. A US king flat (274 × 259 cm) tucks in properly.
Pillowcases in a sheet set
Twin and twin XL sets usually include one standard pillowcase. Full and larger sets include two, sized to the bed: standard cases with full and queen sets, king cases with king and Cal king sets.
| Pillowcase | Inches | Centimeters | For pillow |
|---|---|---|---|
| Standard | 20 × 30 | 51 × 76 | 20 × 26 in |
| Queen | 20 × 34 | 51 × 86 | 20 × 30 in |
| King | 20 × 40 | 51 × 102 | 20 × 36 in |
Shams, Euro squares and body pillow covers are covered in the pillow size guide.
Sheets for toppers, adjustable beds and air mattresses
- With a topper: the pocket must cover both layers. See the thickness options in the mattress topper size guide.
- Adjustable bases: when the head raises, the sheet has to stretch around a bend. Fully elasticized fitted sheets or sheet straps (suspenders) keep the corners on.
- Raised air beds: a queen air bed 18 to 22 in tall needs an extra-deep pocket, and many are 1 to 2 in narrower than a real queen, so the sheet runs loose. Sizes are on the air mattress size chart.
The layer on top of the sheets is sized differently again; see the comforter size chart and blanket sizes.
Frequently asked questions
Will twin XL sheets fit a twin bed?
A twin XL fitted sheet (38 × 80 in) goes on a twin mattress (38 × 75 in) but leaves 5 in of loose fabric that bunches at the foot. A twin fitted sheet will not stretch onto a twin XL, which is 5 in longer.
Does a twin XL fitted sheet fit a full size bed?
No. A twin XL sheet is 38 in wide and a full mattress is 54 in wide, a 16-in difference that elastic cannot cover. Full sheets need a 54 × 75 in fitted sheet.
What size sheets do I need for a college dorm bed?
Almost all US dorm beds are twin XL: 38 × 80 in (97 × 203 cm). Use twin XL fitted sheets, ideally with a 15-in pocket if you add a topper. A regular twin flat sheet (66 × 96 in) is usable, but a twin XL flat (66 × 102 in) tucks in better at the foot.
What are king size sheet dimensions in meters?
A king fitted sheet is 1.93 × 2.03 m (76 × 80 in) plus a pocket of about 0.36 m (14 in). A king flat sheet is about 2.74 × 2.59 m (108 × 102 in).
Do queen sheets fit a full bed?
A queen fitted sheet is 6 in too wide and 5 in too long for a full mattress, so it wrinkles and slips. A queen flat sheet works on a full, giving extra side drop. For the fitted sheet, buy full size (54 × 75 in).
Are Cal king and king sheets the same?
No. A king fitted sheet is 76 × 80 in and a Cal king is 72 × 84 in. On the wrong mattress the sheet is 4 in too wide and 4 in too short, so the corners pop off. Flat sheets and pillowcases interchange more easily.
