If your height is under 160 cm (about 5 ft 3 in), go with Short / Youth bag. Sleeping bags come in length sizes. Pick a bag a little longer than your height so your feet are not jammed against the foot box.
| Your height | Recommended size |
|---|---|
| under 160 cm (about 5 ft 3 in) | Short / Youth bag |
| 160 to 175 cm (about 5 ft 3 in to 5 ft 9 in) | Regular bag |
| 175 to 185 cm (about 5 ft 9 in to 6 ft 1 in) | Regular to Long bag |
| 185 to 198 cm (about 6 ft 1 in to 6 ft 6 in) | Long bag |
| 198 cm and up (about 6 ft 6 in and up) | Extra Long bag |
| Sleep with gear inside the bag | Size up to Long. |
| Cold sleeper | A snugger fit traps more warmth — avoid oversizing. |
| Side sleeper | A roomier or spoon-shaped bag is more comfortable. |
