Furniture layout calculator
Enter your room size, tick the furniture you're planning to fit, and see whether there's still enough floor left to walk around comfortably. Nothing is sent anywhere — it all runs in your browser. Switch units below.
How this is calculated
Floor space isn't just furniture footprint — a room also needs room to walk around what's in it. This calculator reserves a percentage of the floor for walkways and door swing, then checks whether your furniture fits in what's left.
(room area × (1 − walkway %)) − sum of furniture footprints = space left
Worked example for a 4 × 3.5 m bedroom (14 m²) at 25% walkway space, with a queen bed and a wardrobe:
- Usable area: 14 × 0.75 = 10.5 m²
- Furniture: bed 3.2 m² + wardrobe 0.72 m² = 3.92 m²
- Space left: 10.5 − 3.92 = 6.58 m² — comfortable fit
Typical furniture footprints
| Piece | Typical size | Floor footprint |
|---|---|---|
| 3-seat sofa | 2.0 × 0.9 m | 1.8 m² |
| Armchair | 0.8 × 0.8 m | 0.64 m² |
| Coffee table | 1.1 × 0.6 m | 0.66 m² |
| Queen bed | 1.6 × 2.0 m | 3.2 m² |
| Wardrobe | 1.2 × 0.6 m | 0.72 m² |
| Dining table (4) | 1.2 × 0.8 m | 0.96 m² |
| Desk | 1.2 × 0.6 m | 0.72 m² |
| TV unit | 1.5 × 0.4 m | 0.6 m² |
These are common sizes for a first estimate — check the actual dimensions of the piece you're buying, especially for sofas and beds, which vary widely.
If it doesn't fit
- Drop the easiest piece to cut. A coffee table or a second armchair is usually the first thing to go in a tight room.
- Go smaller. A loveseat instead of a 3-seat sofa, a round table instead of rectangular — round corners also make walkways feel wider.
- Push furniture to the walls. Freeing up the centre of the room for circulation usually matters more than the exact spot each piece sits in.

Questions and answers
How do I know if my furniture will fit in a room?
Add up the floor footprint of each piece (width × depth) and compare it to your room's usable area — total area minus roughly 25-35% for walkways and door swing. If the furniture footprint is close to or over the usable area, it will feel cramped even though it technically fits.
How much walkway space does a room need?
A comfortable walkway is at least 90 cm wide, and the space in front of a door needs to stay clear for it to swing. As a rule of thumb, reserve about 30% of a living room's floor area and about 25% of a bedroom's for circulation, more in a small room.
How big is a standard sofa or bed?
A 3-seat sofa is typically about 2.0 × 0.9 m (1.8 m²). A queen bed with its frame is about 1.6 × 2.0 m (3.2 m²). A 4-person dining table is roughly 1.2 × 0.8 m (0.96 m²) before chairs are pulled out, which needs extra clearance on every side.
What if my furniture doesn't fit?
Drop one piece (a coffee table is the easiest to cut), choose smaller versions (a loveseat instead of a 3-seat sofa, a round table instead of rectangular), or push furniture against walls to free up the centre of the room for walking.
