Size your pooja space
What kind of space, how many deities, and how the family uses it.
How this calculator works
- Each type has a base size: niche 2.5 × 1.5 ft at 4 ft high, mandir unit 3 × 1.75 ft at 6 ft high, walk-in room 3.5 × 3.5 ft rising to 5 × 6 ft depending on seating.
- Each deity beyond three widens the space — 0.4 ft for a niche, 0.5 ft for a unit, 0.3 ft for a room. Below three, the base size already accommodates them comfortably.
- Platform height is 30 inches for seated worship and 36 for standing, which puts the principal deity at the correct eye level once the murti's own height is added.
- Clear space in front is 3 ft for a niche or a unit and the room depth less 2 ft for a walk-in.
- Cost = width × height × finish rate, priced on elevation area exactly as any other joinery is.
- The logic is fixed. The same inputs always return the same dimensions.
| Type | Base size | Height | Suits |
|---|---|---|---|
| Wall niche | 2.5 × 1.5 ft | 4 ft | One to three deities, a compact flat |
| Mandir unit | 3 × 1.75 ft | 6 ft | The standard choice in a 2 or 3BHK |
| Walk-in, standing | 3.5 × 3.5 ft | 7 ft | Daily aarti, one person at a time |
| Walk-in, one or two seated | 4 × 4.5 ft | 7 ft | Regular seated worship |
| Walk-in, family seated | 5 × 6 ft | 7 ft | Festival worship with the household together |
Heights are finished internal heights. In a flat with a 10 ft slab and a false ceiling, a 7 ft walk-in leaves room for the ceiling and for an exhaust duct above it.

The details that make a pooja space work
Storage below the platform is the item most often left out and most often missed. A household accumulates lamps, wicks, oil, camphor, incense, spare cloth, prasad containers and festival items, and if there is no drawer they live in a plastic box on the floor beside the unit. Nine to twelve inches of drawer depth under the platform, on full-extension channels, solves it permanently and costs very little.
Lighting should be warm and low, and it should never be a downlight pointed at the deity from directly above — that produces a harsh shadow under the face. A concealed warm strip behind the top fascia, washing down the back panel, is what our projects use, with a separate switch so it can be on without the room lights. Keep the driver outside the unit and accessible.
On the fire question, be practical. A brass or stone lamp plate, a tile or stone lining behind the lamp position, and clear air above it are the three things that prevent a charred laminate panel. Where the unit has doors, they should be able to stay open during aarti without the flame sitting under a shutter. And in a flat with no window in the pooja area, a small 100 mm exhaust on the same switch as the light is worth the ₹3,000 it costs.
Every constant on this page comes from Greenbox site records — measured drawings, signed BOQs and completion certificates from projects delivered between 2023 and 2026 — rounded to the figures an estimator would actually write down. We publish them so the arithmetic can be audited rather than trusted. Treat the output as a planning figure: accurate enough to brief a landlord, a bank or a family, and not accurate enough to sign a contract against.
What this tool does not cover
- Direction and placement, which is a separate question — see the Vaastu room placement tool and the direction checker.
- Idols, murtis and framed images themselves, and their own dimensions, which vary widely.
- Marble and stone cladding weight, which on a wall-hung unit needs an MS bracket rather than plugs.
- Carving and jaali work, which is priced per piece and can exceed the joinery cost.
- Electrical points for the lamp, the bell and any exhaust.
- Doors, shutters and the swing space they need in front of the unit.

Frequently asked questions
What is the ideal size for a pooja room?+
A walk-in pooja room needs at least 3.5 × 3.5 ft for standing worship, 4 × 4.5 ft for one or two seated and 5 × 6 ft for a family seated together. In a flat, a 3.5 × 1.75 ft mandir unit at 6 ft high does the same job in far less space.
How high should the mandir platform be?+
Thirty inches for seated worship and thirty-six for standing, so the principal deity's eyes sit at 42 or 54 inches respectively — level with the worshipper's own. That is the one dimension worth getting exactly right.
Can a pooja unit be made of plywood?+
Yes, and most are. What matters is the lamp area: line it with stone, metal or tile, keep 12 inches of clear height above any flame, and never put a laminate shutter directly over a burning lamp. Plywood with veneer at about ₹2,600 per sq ft of elevation is the standard specification.
Does a pooja room need ventilation?+
Yes. Daily aarti, camphor and agarbatti produce soot, and a sealed niche will stain the ceiling within a year. A small 100 mm exhaust wired to the light switch, or a louvred panel at the top of the unit, solves it for about ₹3,000.
Where should the pooja room be in a flat?+
Traditionally the north-east, and where that is not possible, a north or east wall niche. In practice the constraints are a quiet corner, no shared wall with a bathroom, and somewhere the lamp is not under a low shutter. Our placement tool covers the traditional guidance in detail.
