Budget Mural Paint Volume Before Buying Tins
Paint estimates fail on coats and coverage, not on wall size. Multiply area by coats, divide by the coverage printed on the tin you are using, and buy for the job rather than for the wall.

Optional AI use below leaves this device; it is not required.
Data note: Everything runs in this browser tab on the paint coverage strip: your wall section | area square metres | coats stays on this device, nothing is uploaded, and the reading is rebuilt only when you press run.
Perspective: Before: Order of operations changes the answer: coats multiply the area before coverage divides it. After: the paint coverage strip shows the working beside each named row so the reader can change the assumption and inspect the consequence.

Volume arithmetic on areas, coats and product coverage you supply. Not decorating, chemical-safety or structural advice; check the manufacturer’s coverage, drying and ventilation requirements, and get a specialist opinion on unstable or damp walls.

- Method: Coverage printed on the tin usually assumes a sealed, even surface; take the conservative figure and subtract nothing for optimism. At 8 square metres per litre, 36 square metres needs four and a half litres.
- All sample records are invented examples. The app does not fetch measurements, policies, files or personal records.

Optional AI formatting, not calculation
For this paint coverage strip, use the free AI Studio interface only if available to you, with no paid API key. Manual entry completes the same workflow for free. Supply only fictional or non-sensitive notes. Review its output against the source; never paste unresolved questions into the numeric rows.
Format my non-sensitive notes for a paint coverage strip. Return plain rows only: wall section | area square metres | coats. Preserve supplied quantities exactly. Do not guess missing values; list questions separately. Do not calculate or add advice. I will check every row before pasting into the local tool.
