About Paint Calculator
The Paint Calculator from ToolsOfIndia gives home owners, painters and contractors a quick, dependable way to get answers without wrestling with formulas. Estimate the paint needed for a room or wall by entering the area, the number of coats and the paint coverage, with the tool returning the litres and the cost from a per-litre rate. Emulsion paint covers about 130 to 140 square feet per litre per coat, and the tool accounts for two coats, primer and the wastage that rolling and cutting-in always add. Indian paint is sold in 1, 4 and 20 litre packs, and the tool rounds up to the nearest pack. Because it is a pure local calc, nothing is uploaded. It is the paint estimate that a second shop trip always disrupts. Estimates are framed the way Indian contractors and material suppliers actually quote, so you can compare numbers directly with the local rate card. Common scenarios include estimating paint for a room, costing a painting job from a rate, and ordering paint packs for a wall. Pair it with the related tools listed alongside for a complete workflow.

Frequently Asked Questions
How much paint do I need per square foot?
One liter of paint covers approximately 100-120 sq ft with 1 coat. For 2 coats on a 10x12 ft room (approx 400 sq ft wall area): need about 7-8 liters of paint.
How to calculate paint for a room?
Measure each wall (L×H), add together, subtract doors (21 sq ft) and windows (15 sq ft). Multiply by number of coats. Divide by paint coverage per liter.
What is the difference between interior and exterior paint?
Interior paint is formulated for low-UV, washable surfaces with matte/eggshell finishes. Exterior paint is weather-resistant with UV protection and flexible formulations.
How much paint does a litre cover?
Emulsion covers about 130 to 140 square feet per litre per coat, so a 10 by 12 foot room with two coats needs a few litres.
Do I count primer separately?
Yes, primer is a separate coat and is usually one coat, which the tool counts as an additional line.
