Semrush US · 1,900 searches/mo · KD 23| Label or calculation | Dimensions | What it means |
|---|---|---|
| Nominal Full mattress | about 53–54 × 75 in (134.6–137.2 × 190.5 cm) | Finished mattress widths vary. |
| Example mattress opening | 53⅛ × 74⅜ in (134.9 × 188.9 cm) | Current IKEA MALM specification. |
| Example outer frame | 59 × 78⅜ in (149.9 × 199.1 cm) | Adds about 5⅞ in width and 4 in length. |
Because Full mattress width can be listed at 53 or 54 inches, confirm the mattress and frame opening as a matched pair.
Full saves width compared with Queen
The example Full exterior is about seven inches narrower and almost five inches shorter than the example Queen exterior from the same frame family.
Full XL needs a longer frame
A standard Full frame opening is designed around a 75-inch mattress. A nominal 80-inch Full XL needs a purpose-built longer opening.
