Room / Area Dimensions

How This Paint Calculator Works

The calculator estimates total wall area using room dimensions, multiplies by the number of coats, and divides by paint coverage to calculate how much paint is required.

Frequently Asked Questions

How much paint do I need for a room?

Measure room length, width, and height. The calculator automatically computes wall area and estimates paint required based on coverage and coats.

Does this include ceiling paint?

This calculator estimates wall paint only. Ceiling area can be calculated separately by multiplying length and width.

Should I buy extra paint?

Yes. It is recommended to buy 5–10% extra paint for touch-ups and waste.
