Paint Calculator
Paint Calculator
Estimate paint for rooms, selected walls and ceilings.
Paint coverage comes from the product and the surface, not simply the size of the house.
List the walls or rooms being painted, include ceilings where needed and use the tin's coverage rate. Change coat counts separately from the measured area.
How to use Paint Calculator
- Choose measurement unit and include ceilings.
- Enter finish coats, coverage per coat, container size and ordering allowance.
- Enter price per container.
- Add the entries in rooms and wall selection as separate rows. Include room, length, width, height, long walls, short walls and openings for each row.
- Select Calculate estimate. Read the returned values alongside the assumptions below before copying, exporting or acting on the result.
Why choose this tool?
Selected surfaces and product coverage make comparisons useful when you are choosing between different pack sizes or paint systems.
Before you use the result
Use coverage from your paint tin or product sheet. Primer is a separate product and is not included.
Questions about Paint Calculator
Is primer included?
No. Estimate primer with its own area, coverage and coat requirements. Do not assume the finishing paint quantity covers a separate primer product.
What should I check before using Paint Calculator?
Check Measurement unit, Include ceilings, Finish coats and Coverage per coat. Use the exact units shown beside the controls and replace any example values with your own inputs.
