Door Width Standards for Indian Homes: Room-by-Room Widths & Clear Opening (2026)

Ask three people the width of a "three-foot door" and you will get three different numbers — because the frame, the leaf and the gap you actually walk through are all different measurements, and the one that matters most is the one nobody quotes. A door sold as 900 mm rarely gives you 900 mm to carry a sofa through. This guide sets out the standard door widths for an Indian home room by room, explains the difference between nominal, leaf and clear-opening width, and tells you the minimum width that furniture, prams and wheelchairs genuinely need so you size the opening once and never regret it.

This is the width-specific companion to the broader door size standards guide, which covers heights and the full size table — start there for the complete picture and come back here to get width right. For accessibility-led sizing see wheelchair-accessible doors, and to pick between one leaf or two for a wide opening read single vs double door.

Three widths, not one: nominal, leaf and clear opening

This is the single most useful thing in this guide, so it comes first. When you specify a door, three different widths are in play:

• Nominal / frame size — the outside or "ordering" size of the doorway, the figure a carpenter or builder quotes. A "900 mm door" usually means a roughly 900 mm structural opening or frame width.
• Leaf (shutter) size — the door panel itself, which is smaller than the frame because it sits inside the rebate and needs swing clearance.
• Clear opening width — the actual unobstructed gap when the door is open 90 degrees, measured from the face of the open leaf (or the door stop) to the frame on the far side. This is what your shoulders, your wardrobe and a wheelchair pass through.

The clear opening is always the smallest of the three, and the gap is real. On a hinged door the open leaf, its thickness (30-40 mm), the hinges and the frame rebate all eat into the nominal size. As a working rule of thumb, clear opening is roughly 50-90 mm less than the leaf width for a standard single hinged door. So a 900 mm nominal door with an 810-850 mm leaf typically gives only about 780-820 mm clear — and that is why a 900 mm door is the practical floor for wheelchair access, not a generous margin.

Standard door widths by room (NBC 2016 + common practice)

The National Building Code of India 2016 (Part 3) and everyday Indian building practice settle on a familiar set of widths. Heights are almost always 2100 mm for habitable-room doors; bathrooms often drop to 2000-2100 mm. The table below pairs the nominal width you order with the realistic clear opening you get from a standard single hinged leaf.

Two practical notes. First, an 800 mm kitchen door is the floor, not the ideal — if you ever expect a fridge or a double-burner hob to come through, specify 900 mm. Second, a 700 mm bathroom door is fine for an able-bodied adult but is the first thing to upgrade in a home meant to age in place or accommodate a wheelchair, because its clear opening drops near 620 mm.

Why clear width is the number that bites you

Builders quote nominal width because that is what they buy and chisel into the wall. But every real problem — the wardrobe that will not go into the bedroom, the new fridge stuck in the kitchen doorway, the wheelchair that catches both wheel-rims — is a clear-width problem. Some quick reference loads for an Indian home:

• A person walking comfortably: ~600 mm clear; two people or carrying boxes: ~750-800 mm.
• A standard double-door fridge or front-load washing machine: typically 650-720 mm wide, but you need ~50-75 mm hand clearance, so 800 mm clear is safe.
• A three-seater sofa or a king bed: these go in on the diagonal, so the door height and the corridor turn matter as much as width — but a 900 mm nominal door (810+ clear) is the realistic minimum for moving furniture without scuffed frames.
• A manual wheelchair: needs ≥800-900 mm clear to pass without scraping the user's hands (more on this below).

Because clear width is what counts, the safest habit is to size up one step wherever furniture or future accessibility is plausible — bedrooms to 900, kitchens to 900, the main door to 1100-1200. The cost difference at construction is small; widening a door later means breaking the frame and the wall.

Minimum widths for accessibility

If anyone in the household uses, or may one day use, a wheelchair or walker, design to the RPwD Harmonised Guidelines 2021 rather than minimums. The target is a clear opening of at least 800-900 mm. Because clear width is smaller than nominal, that means specifying a 900 mm nominal leaf as the absolute minimum, and 1000 mm is more comfortable — a 900 mm leaf yields only about 810-850 mm clear, which is right at the edge.

A few companion details make the width usable rather than just technically compliant:

• Threshold ≤ 12 mm and ideally flush — a high dehleez (saddle) defeats a wide door for a wheelchair (see door threshold standards).
• Lever handles, not knobs — easier to operate; mount at a reachable height.
• Approach space — at least ~1200 mm of flat floor in front so a chair can square up to the opening.
• Lighter leaf or a door closer set soft so the door is not a struggle to push.

For the full accessibility picture, including turning circles, corridor widths and bathroom layout, see wheelchair-accessible doors and the broader accessible home design guide.

Single leaf or double? Widening the opening

Beyond about 1000-1100 mm, a single hinged leaf starts to become heavy, sag-prone and a nuisance to swing in a tight room. The usual solutions for wide openings:

• Double doors (two leaves) — common for grand main entrances (e.g. two 600 mm leaves for a ~1200 mm opening). One leaf stays bolted for daily use; both open for furniture and festivals. Even number of panels also sits well with Vastu tradition. See single vs double door and double doors.
• A leaf-and-a-half (uneven pair) — a main 750-900 mm leaf for everyday use plus a narrow fixed/secondary leaf you unbolt only when you need the full width. Popular where space is tight.
• Sliding or French doors — for balcony, terrace and garden openings wider than a single swing handles cleanly, a sliding door or French doors give a wide clear span without swing-space penalty.

For the main door specifically, the rule of thumb is: up to ~1000 mm a single leaf is fine; 1000-1200 mm consider double; above 1200 mm double or a sliding/pivot solution is almost always better.

How to choose your widths (a quick method)

1. Start from the room function. Bath/store/pooja can take the minimums; bedroom and kitchen should not.

2. Then check the biggest object that must pass through over the life of the home — fridge, washing machine, king bed, wheelchair — and convert it to a clear-width requirement (add 50-100 mm to the object).

3. Convert clear width to nominal by adding ~50-90 mm for a hinged single leaf.

4. Round up to a standard size (700, 750, 800, 900, 1000, 1200) so frames and shutters are off-the-shelf.

5. Apply the accessibility floor (900 nominal minimum) anywhere ageing-in-place matters.

You can run the numbers fast with the door size calculator, and pair it with the door cost calculator to see how a wider leaf affects your budget. Brands like Hettich and Hafele publish frame-rebate dimensions that help you verify clear opening before you order.

A note on Vastu and width

In Vastu tradition the main door should be the largest door in the house, ideally placed North, East or North-East, and many homeowners deliberately make it wider and taller than interior doors as a sign of welcome and prosperity. This dovetails neatly with the practical case for a 1100-1200 mm main entrance. An even number of leaves or panels is also preferred. Treat this as tradition reinforced by sensible practice — a wide, well-lit, unobstructed entrance is good design by any measure. For the full treatment see main door Vastu and entrance Vastu.

Frequently asked questions

What is the standard main door width in India?

1000-1200 mm nominal (3.3 to 4 feet) is standard, with 1200 mm common in independent houses and 1000 mm in flats. Height is almost always 2100 mm. The main door is usually the widest door in the home, which also suits Vastu.

Is a 900 mm door wide enough for a wheelchair?

It is the minimum, not the ideal. A 900 mm leaf gives only about 810-850 mm clear opening, which is right at the RPwD Harmonised Guidelines 2021 target of 800-900 mm clear. Prefer a 1000 mm leaf, a low threshold (≤12 mm) and lever handles for comfortable access.

Why is the clear opening smaller than the door size I ordered?

Because the leaf sits inside the frame rebate, has its own thickness (30-40 mm), and the open leaf and hinges intrude into the gap. A single hinged door typically loses 50-90 mm between nominal width and the actual clear opening you walk through.

What is the minimum width for a bathroom door in India?

700-750 mm nominal is the common standard, giving roughly 620-680 mm clear. That is adequate for an able-bodied adult but is the first door to widen to 900 mm if the home needs to be wheelchair-accessible now or in future.

Should a wide opening be a single or double door?

Up to about 1000 mm a single leaf is fine. From 1000-1200 mm consider double doors (two leaves) for a lighter, sag-free swing; above 1200 mm use double, sliding or pivot doors. See the single-vs-double door guide for the trade-offs.
