How to calculate cooling load per square foot
This calculator finds cooling load per square foot by dividing total cooling load by floor area — a normalized figure useful for comparing cooling demand across differently sized spaces.
How the calculation works
Load per sq ft = Cooling load (BTU/hr) ÷ Floor area (sq ft).
Example
A 24,000 BTU/hr load over 1,000 sq ft: Load per sq ft = 24,000 ÷ 1,000 = 24 BTU/hr per sq ft.

Pro Tips for Cooling Load Per Square Foot
- Typical residential loads fall roughly in the 20-30 BTU/sq ft range, though climate, insulation, and sun exposure shift this significantly.
- Use this normalized figure to compare relative cooling demand between rooms, not as a substitute for a full load calculation.
Common Cooling Load Per Square Foot Mistakes to Avoid
- Treating this ratio as precise enough for final equipment sizing without a proper Manual J-style load calculation.
