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.

Frequently asked questions

How is Result calculated?

Result = [Cooling load] ÷ [Floor area].

Is the Cooling Load Per Square Foot free to use?

Yes — every calculator on Simple Calculator Tools is free, runs in your browser, and does not require an account.

Pro Tips for Cooling Load Per Square Foot

  1. Typical residential loads fall roughly in the 20-30 BTU/sq ft range, though climate, insulation, and sun exposure shift this significantly.
  2. 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.
