King size headboard dimensions and measurement example
A current IKEA MALM King bed lists an 82¼-inch product width and 39⅜-inch headboard height around a 76-inch mattress opening. This is one manufacturer example, not a universal King headboard size.
| Label or calculation | Dimensions | What it means |
|---|---|---|
| Nominal King mattress | 76 × 80 in (193 × 203.2 cm) | Mattress-top baseline, not headboard dimensions. |
| Current product width | 82¼ in (208.9 cm) | Listed width of the integrated IKEA MALM King frame/headboard example. |
| Current headboard height | 39⅜ in (100 cm) | Manufacturer-listed headboard height for this example. |
| Width beyond listed opening | 6¼ in total (15.9 cm) | Difference between 82¼ in product width and 76 in mattress opening. |
A standalone King headboard can use different widths, leg spacing, brackets, wings, upholstery, and height references. Verify the exact specification and mounting points.
Use the 82¼-inch example only as a reference
The measurement describes one current integrated frame. It shows why a room plan based only on the 76-inch mattress width can understate the wall span.
Keep width and height as separate checks
Width affects nightstands, switches, and wall clearance. Stated headboard height affects windows and wall features, but it may not describe the panel height above the mattress.
Measurement method
Start with the product and space you actually have.
- 1
Record the mattress or opening. Keep the inner width as a separate reference.
- 2
Measure the full width. Include posts, wings, upholstery, and trim.
- 3
Identify the height reference. Distinguish total height from panel height above the mattress.
- 4
Map the wall. Mark windows, outlets, switches, trim, and nearby furniture.
