A common room planning mistake is sketching furniture positions before knowing actual sizes. A dining table that “comfortably seats six” in the showroom is typically 160–180 cm long; with chairs pulled out on both sides, it needs a wall-to-wall space of at least 320–360 cm. These are the real dimensions to plan from.
All measurements are approximate. Actual dimensions vary by manufacturer; always verify with the product spec before buying. These figures are intended for room planning, not purchasing decisions.
Sofas
| Type | Metric | Imperial | Notes |
|---|---|---|---|
| 2-seater | W: 140–170 cm · D: 85–95 cm · H: 75–90 cm | W: 55–67 in · D: 33–37 in · H: 30–35 in | |
| 3-seater | W: 175–220 cm · D: 85–95 cm · H: 75–90 cm | W: 69–87 in · D: 33–37 in · H: 30–35 in | |
| Corner / L-shape | Long: 240–300 cm · Short: 150–180 cm · D: 85–95 cm | Long: 94–118 in · Short: 59–71 in | Check both arms separately |
| 2.5-seater | W: 155–185 cm · D: 85–95 cm | W: 61–73 in · D: 33–37 in | |
| Loveseat | W: 120–145 cm · D: 80–90 cm | W: 47–57 in · D: 31–35 in |
Sofa depth on a floor plan is the outer body depth. Seat depth (the part you sit on) is typically 50–60 cm — the rest is back cushion. For planning purposes, use the total outer dimension.
Beds
| Type | Metric | Imperial | Notes |
|---|---|---|---|
| Single | 90 × 190–200 cm | 35 × 75–79 in | Frame adds ~10 cm each side |
| Small double | 120 × 190–200 cm | 47 × 75–79 in | |
| Double | 135–140 × 190–200 cm | 53–55 × 75–79 in | |
| King | 150–160 × 200 cm | 59–63 × 79 in | |
| Super king | 180 × 200 cm | 71 × 79 in | |
| EU King | 180 × 200 cm | 71 × 79 in | Common in mainland Europe |
Bed frame dimensions are typically 10–20 cm larger than the mattress on each side. A king-size mattress (160 × 200 cm) usually sits in a frame of about 175–180 × 210–215 cm. Add clearance around the frame — not the mattress — when planning.
Leave at least 60 cm (24 in) on the main access side of the bed and 45 cm (18 in) on the other side. If both sides need regular access, allow 60 cm on both.
Dining tables
| Type | Metric | Imperial |
|---|---|---|
| 2-person | W: 60–75 cm · L: 75–90 cm | W: 24–30 in · L: 30–35 in |
| 4-person rectangular | W: 75–90 cm · L: 120–140 cm | W: 30–35 in · L: 47–55 in |
| 4-person round | Ø 90–110 cm | Ø 35–43 in |
| 6-person rectangular | W: 80–90 cm · L: 160–180 cm | W: 31–35 in · L: 63–71 in |
| 6-person round | Ø 120–130 cm | Ø 47–51 in |
| 8-person rectangular | W: 90–100 cm · L: 200–240 cm | W: 35–39 in · L: 79–94 in |
Allow 75 cm (30 in) from the table edge to the nearest wall or obstruction on all sides with chairs — enough for someone to pull out a chair and sit down. On sides that only need walk-through access, 90 cm (36 in) is more comfortable. Tables with extension leaves should be planned at their extended size.
Wardrobes and storage
| Type | Metric | Imperial | Notes |
|---|---|---|---|
| Single wardrobe | W: 50–60 cm · D: 58–60 cm · H: 180–220 cm | W: 20–24 in · D: 23–24 in · H: 71–87 in | |
| Double wardrobe | W: 90–120 cm · D: 58–60 cm · H: 180–220 cm | W: 35–47 in · D: 23–24 in · H: 71–87 in | |
| Triple wardrobe | W: 135–180 cm · D: 58–60 cm · H: 180–220 cm | W: 53–71 in · D: 23–24 in | |
| Sliding door wardrobe | D: 58–65 cm — no swing clearance needed | D: 23–26 in | Door slides into itself |
| Chest of drawers | W: 60–100 cm · D: 40–50 cm · H: 70–110 cm | W: 24–39 in · D: 16–20 in · H: 28–43 in | Add ~50 cm drawer clearance |
Hinged wardrobe doors require clear floor space equal to the door width in front of the wardrobe. A double wardrobe with two 50 cm doors needs 50 cm of clear space in front — not just to open the doors, but to access the contents comfortably.

Planning with real dimensions
Once you have the sizes, the next step is placing them in your room to see what actually fits. Upload your floor plan image to Layoutr, click two points on the plan with a known real-world distance between them, and the tool sets the scale automatically. From there, drag furniture pieces with real dimensions onto your plan and see exactly what fits and what does not — before ordering or moving anything.
Frequently asked questions
What is the standard depth of a sofa?
Most sofas are 85–95 cm (33–37 in) deep from the front of the seat cushion to the back of the sofa body. Some deep-seat or modular sofas go up to 110 cm (43 in). Remember that the depth of the sofa on your floor plan is the outer body depth — armrests usually add nothing to the depth, only to the width.
What is the smallest double bed?
A standard double (full) mattress is 135 × 190 cm (53 × 75 in). The bed frame is typically 10–20 cm larger on each side, making the overall footprint roughly 155 × 210 cm (61 × 83 in) depending on the design. A small double (120 × 190 cm) exists but is less common; it is 15 cm narrower than a standard double.
How much space does a 6-seater dining table need?
A 6-seater rectangular table is typically 160–180 cm (63–71 in) long and 80–90 cm (31–35 in) wide. With chairs pulled out on both long sides (75 cm / 30 in each) and space at each end for circulation, the minimum room area needed from wall to wall is around 330–360 cm (130–142 in) wide and 280–300 cm (110–118 in) long.
How deep is a standard wardrobe?
Standard wardrobe depth is 58–60 cm (23–24 in). This accommodates clothes hung on a rail without the hangers touching the back panel. Built-in wardrobes with sliding doors use the same depth. Wardrobes with hinged doors need additional clearance in front equal to the door width — typically 50–60 cm (20–24 in) of clear floor space.
Can I use these sizes for planning in a room planner tool?
Yes. In a tool like Layoutr, you set the real-world scale from your floor plan image, then place furniture pieces that represent real dimensions. The sizes in this guide match what you would enter or find in the built-in furniture catalog. What you see on the plan is what you get in the room.
