How to calculate dehumidifier capacity
This calculator estimates dehumidifier capacity needed based on room area and a moisture factor.
How the calculation works
Capacity = (Area ÷ 100) × Moisture factor.
Example
1,000 sq ft at a moisture factor of 12 pints per 100 sq ft: (1,000÷100)×12 = 120 pints (per day, per typical rating convention).

Pro Tips for Dehumidifier Capacity
- Moisture factor should reflect your space's actual dampness level (higher for very damp basements, lower for dry above-grade rooms).
- Match calculated capacity to standard dehumidifier sizes, rounding up rather than down.
Common Dehumidifier Capacity Mistakes to Avoid
- Using a low moisture factor for a genuinely damp space (like a basement with visible moisture issues), which would undersize the dehumidifier.
