Estimate paint quantity
Estimates how much paint you need from the wall area and specified coverage.
Works out the wall area of a room and from that the paint you need, including multiple coats.

- Set the number of doors and windows, and the coverage

We subtract a flat 2 m² per door or window — an average. With very large windows, check it yourself. The ceiling is not included.
Frequently asked
What does it cost?
Every tool shows its price before you start. Tools marked free run in your browser and never cost anything — no sign-up needed.
What happens if processing fails?
You are not charged. We only charge when a result is actually produced; if the run fails, the charge is reversed.
What happens to my files?
Uploaded files are processed in memory for that one request and then discarded. We do not store them, and their contents never reach our logs or analytics.
Do you use my own API key?
No. Your BYOK key belongs to the Playground and is never used for these tools.
