How much paint, and what will it cost?

For a single-storey 5 Marla house the planner assumes about 2,800 sq ft of interior walls, 1,000 sq ft of ceilings and 900 sq ft of exterior walls. At two coats that is roughly 81 litres of wall, ceiling and exterior paint, plus a separate primer (about 28 litres) and enamel for doors and windows. The real figure depends on your covered area, wall height, openings, surface condition and the paint you choose, so enter your own measurements in the calculator above.

The 7 Marla planning example uses about 3,920 sq ft of interior walls, 1,400 sq ft of ceilings and 1,260 sq ft of exterior walls. At two coats that is roughly 114 litres of paint, with about 40 litres of primer. Select the 7 Marla preset in the calculator and adjust the areas, coats or coverage to match your actual house.

Single-storey 8 Marla planning areas are about 4,480 sq ft of interior walls, 1,600 sq ft of ceilings and 1,440 sq ft of exterior walls. Two coats come to roughly 130 litres of paint and about 46 litres of primer. Choose Custom size in the calculator, enter 8 Marla and fine-tune each surface for a closer figure.

A single-storey 10 Marla house is planned at roughly 5,600 sq ft of interior walls, 2,000 sq ft of ceilings and 1,800 sq ft of exterior walls — about 163 litres of paint at two coats and about 57 litres of primer. A double-storey 10 Marla house has much more wall and ceiling area, so expect a significantly higher quantity; switch the structure toggle to Double-storey in the calculator.

The 12 Marla example assumes about 6,720 sq ft of interior walls, 2,400 sq ft of ceilings and 2,160 sq ft of exterior walls. At two coats that is roughly 195 litres of paint and about 68 litres of primer. Measure your own rooms and deduct large openings for a more accurate estimate.

For a single-storey 20 Marla house the planner assumes about 11,200 sq ft of interior walls, 4,000 sq ft of ceilings and 3,600 sq ft of exterior walls, which is roughly 325 litres of paint at two coats and about 114 litres of primer. Larger or double-storey homes can need considerably more, so use your own areas where possible.

Interior painting covers bedroom, living, dining, hall and staircase walls plus ceilings. For the single-storey 5 Marla example that is about 3,800 sq ft of walls and ceilings, roughly 63 litres at two coats at the default 120 sq ft per litre per coat. Calculate each room with 2 × (length + width) × height, add length × width for the ceiling, deduct doors and windows, then confirm the coverage of your chosen emulsion.

Exterior paint is measured from the exposed front, side and rear walls, plus boundary walls if you are painting them. The 5 Marla planning example uses about 900 sq ft of exterior wall, roughly 18 litres at two coats at an assumed 100 sq ft per litre per coat. Measure width × height for each wall, deduct openings and use the coverage of the exterior product you choose.

A ceiling needs length × width for each room, then the same coats and coverage calculation as the walls. The 5 Marla example has about 1,000 sq ft of ceiling, around 17 litres at two coats. Calculate ceilings separately if you are using a different colour or product from the walls.

Doors, windows, grills, railings and gates use enamel rather than wall emulsion and are estimated separately. As a planning rule the calculator allows about 50 sq ft of enamel surface per Marla, so roughly 250 sq ft for a 5 Marla house. Measure the actual items and ask Triangle Paints to confirm the undercoat and enamel system.

Calculate the paintable area (interior walls + ceilings + exterior walls), multiply by the number of coats, then divide by the paint's coverage in square feet per litre per coat to get litres. Multiply litres by the price per litre for the material cost, then add primer, putty and enamel, and finally add painter labour. The calculator above does this with editable coverage and price assumptions and shows a material total, a rough labour total and your approximate saving with Triangle Paints.

Painter labour is a separate charge from paint material and is normally quoted per square foot of paintable area. Rates vary with city, surface, height, surface condition and scope, so the calculator starts from an editable Rs 20 per sq ft planning rate that you can change to match quotes in your area. Triangle Paints can also arrange painting labour — contact us for availability and a labour quote.

Two finish coats is the usual choice for interior and exterior repainting and is the calculator default. New plaster, a strong colour change or a damaged surface may need a primer plus two or three coats. Always follow the product's application instructions and confirm the right system for your walls.

Generally yes. A double-storey house on the same plot has more interior wall and ceiling area, and often more exterior wall area, so it needs more paint — but not exactly double. Use the Single-storey / Double-storey toggle in the calculator, or enter your own measured areas, to see the difference for your layout.

Primer and putty depend on the wall condition and the paint system. The calculator estimates primer from the interior and exterior wall area using an editable coverage (default 130 sq ft per litre for one coat) and estimates putty from the same wall area. New or porous plaster usually needs a primer, while putty is used to fill and smooth minor imperfections. Confirm whether your walls need putty, sealer or primer before buying.

Gross wall area = 2 × (length + width) × height. Deduct openings (width × height × quantity) to get the net paintable area, add length × width if you are painting the ceiling, multiply by the number of coats, then divide by the product's coverage in square feet per litre per coat. For example, a 12 ft × 10 ft room with a 10 ft height has 440 sq ft gross, 380 sq ft net after a door and a window, and 760 sq ft over two coats.

It is a planning estimate, not a quotation. It converts your measurements into paintable area, coat area, rough litres and an indicative cost using editable coverage rates and prices, so the result changes with the assumptions you enter. Actual consumption depends on the product, surface porosity, colour change, application method and wastage.
