Mattress & Bedroom Fit Calculator
Enter the bedroom size, the mattress width and where the wardrobe sits to see the bed frame footprint, the walking space on each side and the bedside table that actually fits — before the bed is delivered.
A bed that fits the wall is not the same as a bedroom that works. The usable part is what is left after the frame and the wardrobe: you need about 60 cm at the foot of the bed to walk, and about 60 cm beside it to get in and make the bed. Enter the room and the mattress; the page shows the leftover space and the largest size that still works.

Typical space each size needs
| Mattress | Frame | Room needed |
|---|---|---|
| 1.0 × 1.9 m | 108 × 200 cm | 2.4 × 2.6 m |
| 1.2 × 1.9 m | 128 × 200 cm | 2.6 × 2.6 m |
| 1.5 × 2.0 m | 158 × 210 cm | 2.9 × 2.7 m |
| 1.8 × 2.0 m | 188 × 210 cm | 3.2 × 2.7 m |
Room needed assumes a walkway on both sides and no wardrobe.
Clearance rules of thumb
- Foot of the bed: at least 60 cm to walk past; 80 cm if a wardrobe or a desk is also on that wall.
- Sides of the bed: at least 60 cm to get in; 45 cm is the absolute minimum for a single sleeper.
- Bedside table: allow 40–50 cm of width on top of the 60 cm walkway, otherwise skip the table.
- Wardrobe with hinged doors needs the door swing in front of it — 50 cm is realistic, not 20 cm.
- A bedroom under 9 m² is usually better with 1.2 m than 1.5 m; the extra width costs walking space on both sides.

Reference dimensions for planning. Frames differ in thickness, radiators and skirting boards take space, and doors need clearance — check the actual frame drawing before ordering.
