AC Size by Room Area
Floor area is useful for a quick starting point, but ceiling height, city, sun, insulation, windows and occupancy can move the result substantially.
| Room area | Use this as a starting point |
|---|---|
| 15 m² | Calculate 15 m² → |
| 20 m² | Calculate 20 m² → |
| 25 m² | Calculate 25 m² → |
| 30 m² | Calculate 30 m² → |
| 40 m² | Calculate 40 m² → |
| 50 m² | Calculate 50 m² → |
Why area alone is not enough
A shaded bedroom with good insulation is not the same load as a top-floor living room with large glazing and direct sun. Use the calculator for a personalised estimate rather than treating an area table as a final specification.
