Beds are the one furniture purchase sized in inches but lived in millimetres. Indian mattress and bed-frame makers work to a settled set of inch sizes — 72×36 for single, 72×48 for double, 78×60 for queen, 78×72 for king — while architects plan rooms in millimetres and clearances. The mismatch is where bedrooms go wrong: a king bed ordered for a 10 ft-wide room leaves no dressing clearance, and a "queen" from one maker can be 75 inches long while another's is 78, which matters enormously when the frame is built into a wall-to-wall design.
This article converts the Indian market sizes to exact millimetres, adds the frame and mattress build-up, and — most importantly — works backwards from each bed to the room it needs. Time-Saver Standards planning guidance puts a minimum bedroom at 10 ft × 12 ft (3.05 × 3.66 m) excluding closets and a master at 12 ft × 16 ft (3.66 × 4.88 m); NBC 2016 sets the legal floor for a habitable room at 9.5 sq m with 2.4 m minimum width and 2.75 m ceiling height. Between those two authorities sits every real bedroom decision.
What it settles: the four Indian standard bed sizes in mm, how mattress thickness and frame design change the numbers, the clearance each bed needs on each side, and the minimum room that holds each bed without compromise.
The Indian standard sizes — in millimetres
The Indian mattress industry builds to inch sizes, and the commonly cited market standards convert as follows. Note the two length families: 72-inch (1829 mm) beds for single and double, 78-inch (1981 mm) for queen and king, with 75-inch and 84-inch lengths also offered by some makers for tall sleepers. Neufert's Architects' Data records slightly different European frame sizes (single 950 × 1950, double 1500 × 1950), which is worth knowing when reading imported furniture catalogues — a "double" in a European catalogue is not the Indian 72×48.
Mattress thickness is the forgotten dimension. Commonly cited Indian market practice runs 100 mm (4 in) for basic coir and foam, 150 mm (6 in) for standard spring and memory foam, and 200 mm (8 in) for premium pillow-top mattresses. The total sleeping height — frame base plus mattress — typically lands at 550–650 mm, and the bedside table (450–600 mm wide per trade standards) is sized to bring its top roughly level with the mattress top, so a lamp and a glass of water sit within easy reach.
| Bed (Indian market name) | Inches (W × L) | Millimetres (W × L) | Sleeps / notes |
|---|---|---|---|
| Single | 36 × 72 | 914 × 1829 | One adult; kids' rooms, guest rooms, hostels |
| Double (full) | 48 × 72 | 1220 × 1829 | Two adults, snug; the common Indian master-bedroom size |
| Queen | 60 × 78 | 1524 × 1981 | Two adults comfortably; needs a 78-inch-long room fit |
| King | 72 × 78 | 1829 × 1981 | Two adults luxuriously; the room-size driver |
| Diwan / single diwan | 30 × 72 (762 wide) | 762 × 1829 | Day-bed; narrow rooms and living-cum-guest spaces |
| Single (Neufert frame) | 37 × 77 | 950 × 1950 | European catalogue reference — longer and slightly wider |
| Double (Neufert frame) | 59 × 77 | 1500 × 1950 | European catalogue reference |
| Child's bed (Neufert) | 28 × 55–67 | 700 × 1400–1700 | Grows with the child; plan for the adult bed later |
| Mattress thickness (commonly cited) | 4 / 6 / 8 in | 100 / 150 / 200 mm | Basic / standard / premium; sets sleeping height 550–650 mm |
| Bedside table width | 18–24 in | 450–600 mm | Trade standard; top ≈ level with mattress |
The section shows why "bed height" is really two numbers: the frame base (typically 250–300 mm to the top of the slats) and the mattress (100–200 mm). The 550–650 mm sleeping height that results is the ergonomic target — low enough to sit on the edge with feet flat, high enough to stand up without effort. Storage beds complicate the arithmetic: the hydraulic or drawer base adds 50–100 mm, so the mattress should be chosen thinner to hold the same sleeping height. And the headboard, commonly 900–1200 mm tall overall, should rise at least 600 mm above the mattress to read as a headboard rather than a rail.
The room each bed needs
A bed's footprint is the smallest part of its room requirement. Time-Saver Standards planning guidance sets the clearances: at least 1.0 m at one side or the foot of the bed for dressing, 0.5 m on one side for circulation, 0.3 m on the least-used side of a double bed, 0.9 m in front of any dresser or wardrobe, and 0.15 m between the bed side and a dresser. Add these to the bed's millimetres and the minimum room draws itself — the table below does the arithmetic for the standard layouts.
| Bed | Bed size (mm) | Minimum room (mm) | How it adds up |
|---|---|---|---|
| Single 914 × 1829 | 914 × 1829 | 2400 × 3000 | Bed 914 + 1000 dressing one side + 500 other side; length 1829 + 1000 foot clearance |
| Double 1220 × 1829 | 1220 × 1829 | 2700 × 3000 | Bed 1220 + 1000 + 500 sides; 1829 + 1000 foot |
| Queen 1524 × 1981 | 1524 × 1981 | 3000 × 3300 | Bed 1524 + 1000 + 500 sides; 1981 + 1200 foot incl. bench/dresser |
| King 1829 × 1981 | 1829 × 1981 | 3300 × 3600 | Bed 1829 + 1000 + 500 sides; 1981 + 1500 foot zone |
| Diwan 762 × 1829 | 762 × 1829 | 2100 × 2700 | Narrowest workable guest room; one-side access |
Two checks sit behind these room sizes. First, the NBC 2016 floor: a habitable room must be at least 9.5 sq m with 2.4 m minimum width and 2.75 m ceiling height — every room above clears it, but a 2400 × 3000 single room (7.2 sq m) would not qualify as a habitable bedroom under NBC; it is a study or store that happens to hold a bed. Second, the TSS planning guidance: a proper minimum bedroom is 3.05 × 3.66 m (10 × 12 ft) and a master 3.66 × 4.88 m (12 × 16 ft), both excluding closets. The king's 3300 × 3600 mm room sits just under the TSS master — which is why kings belong in master bedrooms, not in "bedroom 2".
The plan is the article's working tool: place the bed, then draw the clearances before anything else — wardrobe, dresser, door swing. The 1000 mm dressing side is non-negotiable for a bed used daily; the 500 mm side is circulation only. The wardrobe's 900 mm front clearance (TSS) is the dimension most often forgotten: a wardrobe drawn 600 mm from the bed's foot looks fine on plan and fails the day someone tries to open it while the bed is occupied. Door swings must be drawn too — a 900 mm bedroom door (NBC-derived standard) sweeping into the 500 mm circulation side erases it.
The chart delivers the uncomfortable truth: the bed itself is only a third of the room. A king's 3.6 sq m footprint demands an 11.9 sq m room once clearances are honoured — and the NBC 9.5 sq m line shows that single and double beds in minimum-clearance rooms fall below the habitable-room floor. That does not make such rooms illegal (NBC's 9.5 sq m applies to the room as built, and many older flats predate it), but it explains why a double bed in a 9 × 10 ft room always feels cramped: the clearances were sacrificed, and the body knows it.
What the bed costs: the frame behind the mattress
Mattress prices belong to the mattress market and vary too widely to band honestly here. The bed frame — the carpentry — is where interior budgets live, and its cost is driven by the board in the carcass. A bed base is structural: it carries dynamic load every night, so the honest specifications are solid wood or BWR plywood (IS 303); MDF is acceptable only for headboards and decorative panels in dry rooms, and particle board has no place in a bed frame. The indicative board bands below are material-only, per square foot of 18 mm board.
| Bed-frame material (18 mm board, material only) | ₹ per sq ft, indicative | Where it belongs in the bed |
|---|---|---|
| BWR plywood (IS 303) | ₹90–130 | Base frame, slat bearers — the structural choice |
| BWP / marine plywood (IS 710) | ₹120–180 | Only where the bed meets moisture — rarely needed |
| HDHMR | ₹90–120 | Headboard panels for painted finishes |
| MDF (interior grade) | ₹55–75 | Headboard decoration, CNC panels — never the load frame |
| Pre-laminated particle board | ₹25–45 | Not recommended for bed frames |
| Solid wood (teak, sheesham etc.) | Verify locally | Premium frames — species and seasoning decide the price |
Fit guide — bed to room
- Kids' room / guest room (9 × 10 ft and up): single 914 × 1829 — leaves genuine study and wardrobe space; add a second single only above 10 × 12 ft.
- Standard bedroom (10 × 12 ft / 3.05 × 3.66 m): double 1220 × 1829 — the TSS minimum bedroom holds it with proper clearances.
- Master bedroom (12 × 14 ft and up): queen 1524 × 1981 — needs 78-inch length clearance; check the door swing against the foot zone.
- Large master (12 × 16 ft / 3.66 × 4.88 m): king 1829 × 1981 — the TSS master guidance; 1000 mm dressing clearance on one side is finally comfortable.
- Narrow / multipurpose rooms: diwan 762 × 1829 — day seating by day, single bed by night; the only honest bed for rooms under 9 ft wide.
- Tall sleepers (above 6 ft): look for 75-inch or 78-inch lengths even in single/double widths — the extra 3–6 inches of length matters more than width.
- Avoid: king in a room under 11 ft wide (dressing clearance dies); any bed where the wardrobe door cannot open fully; headboards taller than the window sill they sit against.
