Need Advice on Estimating Paint for My Room

#1 · April 6, 2026, 11:10 am

Hi everyone,

I’m planning to repaint my living room and want to make sure I buy the right amount of paint. I’ve measured the walls, but I’m unsure how to calculate coverage considering windows, doors, and multiple coats.

I came across a Walls paint calculator online, but I’m not sure how accurate it is. Has anyone used one before? How reliable are these tools for estimating paint quantities? Any tips on avoiding waste or ensuring I have enough for touch-ups would be really helpful.

Thanks in advance!

For estimating paint, measure the length and height of each wall, add the areas together, then subtract large doors or windows. Check the paint can for its coverage per litre and plan for two coats if needed. If you’re also choosing a custom shade, knowing how to make pink without red or magenta can be useful when mixing lighter colors for small touch-ups.
