Under about 120 sq ft, 1 Ton is enough. Between 120–190 sq ft, go with 1.5 Ton — most Indian bedrooms fall right in this range, which is why it's the size we see chosen most often. Strong sun exposure or a hotter city can push you toward the bigger option even within that range, so run your exact room through the calculator below rather than going by floor area alone.

Tonnage is about matching cooling capacity to your room's actual heat load, not just floor area — a west-facing room in Hyderabad needs more capacity than the same size room in Bengaluru.
