Dehumidifier sizing calculator
Commercial Dehumidifier Sizing Calculator
Size a commercial dehumidifier from area and dampness to form an early dehumidifier capacity class, then carry current RH, target RH, temperature, moisture source, drainage, and duty cycle into model selection.
Commercial Dehumidifier Sizing Calculator: Form an early screening class from area and dampness, then use current RH, target RH, temperature, moisture source, drainage, duty cycle, and service access to review the selected model. The result is not a guaranteed final RH outcome.

Moisture Inputs
The result is most useful when it carries moisture source, current RH, target RH, drainage, and duty cycle into equipment selection.
- Measure the space and capture current RH, target RH, visible moisture, odor, or stored-material risk.
- Enter area and dampness level to form a screening pints/day class; keep the remaining inputs attached to the equipment selection.
- Review area, current RH, target RH, temperature, moisture source, drainage, and duty cycle together; only area and dampness feed the displayed screening class.
Result use
Recommended next step
Moisture source, current RH, target RH, temperature, drainage, and duty cycle can change equipment selection even when floor area is the same.
Carry Forward
Moisture source
Visible dampness, stored materials, showers nearby, or water entry can change the sizing path.
