How Much Space Does a Wall Bed Need? Wall Width, Ceiling Height and Room Depth

By DWALS Team · Last updated October 2026

How much space does a wall bed need? It comes down to three numbers: wall width, ceiling height and room depth. Closed, a DWALS wall bed stands 12 inches deep. For planning, DWALS’s stated rules are the mattress width plus 4 inches of wall, and the mattress length plus about a foot of room depth to walk past it. If the ceiling is low, or a window or beam is in the way, the bed can be built horizontal instead.

This guide shows you how to measure each of those numbers in your own flat, which Mumbai features change the answer, and when to hand the tape over to someone who does this every day.

How we wrote this: every DWALS rule and figure below is as published on dwals.in on 4 October 2026, and linked. Where DWALS doesn’t publish a number, we say so, and tell you it’s checked at the free measurement instead.

Why US Murphy bed sizes don’t fit Indian flats

Many “Murphy bed dimensions” guides online are written for American homes, and they’re built around American mattresses. A standard US queen mattress is 60 × 79.5 inches, so about 6 ft 8 in long (US mattress sizes). DWALS builds around Indian sizes instead: single 3×6 ft, double 4×6 ft, queen 5×6 ft and king 6×6 ft (DWALS mattress FAQ).

That length difference matters. When a wall bed opens, the mattress length decides how far into the room it reaches. So the room-depth and ceiling figures in US guides won’t match a bed built for a 6 ft Indian mattress. Use them for general ideas, not for planning your room.

The three measurements that decide it

1. Wall width

DWALS’s stated planning rule for a vertical bed is to allow the mattress width plus 4 inches of clear wall (DWALS fit FAQ). “Clear” is the important word. Measure the flat, usable wall between corners, door frames, windows or anything else the cabinet can’t sit over, not the full length of the room.

If you have more wall to spare, side cabinets can sit either side of the bed. DWALS says a full wall unit starts to make sense from about 10 ft of wall, which allows a queen bay in the middle, a 60 cm wardrobe on each side and lofts across the top (Full Wall Units).

2. Ceiling height

A vertical wall bed stands upright, so it needs height. DWALS’s vertical cabinet stands about 6 ft 9 in tall. Ceiling height rarely stops a vertical bed in Mumbai flats, DWALS says, but if yours is under 7 ft 2 in, or a beam or window sits in the way, it builds the bed horizontal instead (DWALS fit FAQ). A horizontal bed folds sideways from a lower, wider cabinet.

Measure the ceiling height at the wall you’d use, not in the middle of the room. A beam, a dropped ceiling or a loft along that wall is what really decides it.

3. Room depth when open

This is the measurement that’s easiest to forget. When the bed is down, it reaches out into the room, and you still need to walk past it. DWALS’s stated planning rule is that the room needs the mattress length plus about a foot to walk past the foot of the bed (DWALS fit FAQ).

Measure from the wall you’d use straight across to the nearest fixed obstacle: the opposite wall, a wardrobe, a sofa you’ll keep, or the edge of a door’s swing.

Closed depth: 12 inches

Closed, a DWALS wall bed projects 12 inches (305 mm) from the wall, with the mattress and bedding inside (DWALS space comparison). That’s the strip of floor it takes during the day.

Mattress size and the space to plan for

DWALS builds around four Indian mattress sizes: single 3×6 ft, double 4×6 ft, queen 5×6 ft and king 6×6 ft (DWALS mattress FAQ). Its two stated planning rules apply to each of them:

• Wall width: the mattress width plus 4 inches of clear wall, for a vertical bed.
• Room depth when open: the mattress length plus about a foot to walk past the foot of the bed.

For a single, DWALS publishes exact figures: 3 ft 4 in of wall and, when open, about 7 ft 2 in of room depth. A horizontal single needs less depth still (Kids Wall Beds).

Mattress	Size (W × L)	Wall	Room depth when open	Source
Single (vertical)	3 × 6 ft	3 ft 4 in	about 7 ft 2 in	Kids Wall Beds

For a double, queen or king, use the two rules to see whether your room is in the right range, then let the site measurement confirm the exact cabinet width and open depth. Skirting, the wall finish and the configuration you choose all affect the final numbers. If your mattress isn’t one of the four sizes above, measure it and mention it at the measurement.

Vertical or horizontal: which suits your room?

• Choose vertical if you have the ceiling height and enough clear wall width. It takes less wall width than a horizontal bed.
• Choose horizontal if your ceiling is under 7 ft 2 in, or a window or beam sits in the way (DWALS fit FAQ). It also suits rooms with a loft. DWALS shows a horizontal bed fitted under a loft in a children’s room (DWALS before and after), and a horizontal single under a loft with a desk beside it (Kids Wall Beds).

At DWALS, a vertical wall bed starts from ₹70,000 and a horizontal one from ₹85,000 (DWALS price list). For what drives the price, see our wall bed price guide for Mumbai.

What else in a Mumbai flat changes the answer

The three measurements get you most of the way. These are the things a tape measure along a bare wall won’t show you. DWALS doesn’t publish clearance figures for them, so note each one down and point it out at the measurement.

Ceiling fans, lights and AC units

A vertical cabinet stands about 6 ft 9 in tall, and the bed swings out from it as it opens. Note the position and height of any ceiling fan, hanging light or split-AC unit on or near that wall. A split AC mounted high on the same wall can clash with the top of the cabinet, and a fan or light in front of it needs checking against the bed’s swing.

Windows, beams and lofts

A window on the wall you want to use, a beam running across it or a loft above it can each rule out a vertical bed at that spot. In each case, a horizontal bed is the usual answer (DWALS fit FAQ). Note the sill height of any window and the height of the underside of any beam or loft.

Doors, switchboards and skirting

• Doors: check that no door, including a wardrobe or balcony door, swings into the space where the open bed will be.
• Switchboards and sockets: a switchboard behind the cabinet will be covered, so plan where it moves, or where the bed goes instead.
• Skirting: skirting tiles along the bottom of the wall can affect how the cabinet sits flush. Measure their height and depth.

Wall type and renting

DWALS fixes its cabinets to the wall with anchors sized for brick, RCC or block walls, through a few points along the back, with no civil work. If you move, its team dismantles the bed, re-installs it in the new home and re-tunes the mechanism for the new wall. The anchor holes left behind are filled and painted over (DWALS wall-fixing FAQ). In a rented flat, get your landlord’s agreement first.

How to measure your room in five steps

1. Pick the wall, and measure its clear width between corners, door frames, windows and any built-in furniture.
2. Measure the ceiling height at that wall, and note any beam, loft, dropped ceiling or window above 6 ft.
3. Measure the room depth from that wall straight across to the nearest fixed obstacle.
4. Mark the extras: fans, lights, split ACs, switchboards, sockets, skirting and every door that swings into the room.
5. Note your mattress size, or the one you plan to buy, then compare your numbers with the table above.

Wall bed with sofa: plan for about 9 ft

A wall bed with a sofa in front needs more room depth, because the sofa stays in front of the wall. On DWALS’s design, the sofa adds about 85 cm in front of the wall. In a room under 9 ft deep, that crowds the walkway, so DWALS suggests side cabinets instead (Murphy bed with sofa (wall bed + sofa)). If you’re still choosing between this and a sofa-cum-bed, our wall bed vs sofa-cum-bed guide compares them for a Mumbai 1BHK.

Let DWALS measure your room

The planning rules in this guide will tell you whether a wall bed is worth looking at for your room. The final numbers come from measuring the room itself. DWALS measures your wall for free across Mumbai and the MMR, and then shares a 3D layout before you confirm anything (DWALS process).

FAQ

How much space does a wall bed need?

A wall bed needs three things: enough clear wall width, enough ceiling height and enough room depth for the bed to open. DWALS’s stated planning rules are the mattress width plus 4 inches of wall for a vertical bed, and the mattress length plus about a foot of room depth. Closed, a DWALS wall bed is 12 inches deep.

How deep is a wall bed when closed?

A DWALS wall bed projects 12 inches (305 mm) from the wall when closed, with the mattress and bedding inside.

What ceiling height does a vertical wall bed need?

DWALS’s vertical cabinet stands about 6 ft 9 in tall. If your ceiling is under 7 ft 2 in, or a beam or window is in the way, DWALS builds the bed horizontal instead.

Do US Murphy bed sizes apply in India?

Not directly. A standard US queen mattress is about 6 ft 8 in long, while DWALS builds around Indian mattress sizes, which are 6 ft long. Because the mattress length decides how far the bed reaches into the room when open, plan with figures for the mattress you’ll actually use.

Can a wall bed fit in a 10×10 ft room?

Room size alone doesn’t decide it. Measure the clear wall width, the ceiling height at that wall and the room depth from that wall to the nearest fixed obstacle, then note fans, ACs, doors, windows and switchboards. Compare those numbers with DWALS’s planning rules, and confirm the answer with a site measurement.

Can a wall bed go under a loft or near a window?

Yes, usually as a horizontal bed. DWALS builds horizontal when a window or beam is in the way, and shows horizontal beds fitted under lofts in children’s rooms.

Does the wall type matter?

DWALS fixes its cabinets with anchors sized for brick, RCC or block walls, with no civil work. The wall type is checked at the site measurement.

How much space does a wall bed with sofa need?

On DWALS’s design, the sofa adds about 85 cm in front of the wall, so DWALS recommends a room about 9 ft deep. For shallower rooms, it suggests side cabinets instead.
