Heating, Cooling & Ventilation calculator
Dehumidifier Size Calculator
Estimate a dehumidifier extraction-capacity range from room area, ceiling height and damp severity.
Estimate a dehumidifier extraction-capacity range from room area, ceiling height and damp severity. Enter the project measurements first, then replace any default material or performance value with data for the product you intend to use. Check temperature, humidity and lab ratings carefully. A dehumidifier rated at warm, humid laboratory conditions may remove much less water in a cool room. Compare ratings at conditions close to your space.
What you need to enter
The Dehumidifier Size Calculator uses the following project information to calculate the result.
- Room area
- Ceiling height
- Damp level

Suggested extraction capacity range
How the Dehumidifier Size Calculator works
This page is built around consumer sizing estimator based on room volume and damp severity. Applied to a suggested dehumidifier extraction-capacity range from room size and damp severity, the engine first converts compatible measurements to a common basis and then calculates suggested extraction capacity range. Verify temperature, humidity and lab ratings before treating the output as a buying, sizing or set-out figure.
Dehumidifier Size Calculator worked example
Dehumidifier Size Calculator example: For a room, enter floor area, ceiling height and the observed damp severity. The calculator uses room volume and severity to suggest a capacity range, which should then be compared with extraction ratings at the room's likely temperature and humidity. This example shows the arithmetic only; on a live job, review temperature, humidity and lab ratings before turning the result into an order or final size.
Important calculation assumptions
For a suggested dehumidifier extraction-capacity range from room size and damp severity, a dehumidifier rated at warm, humid laboratory conditions may remove much less water in a cool room. Compare ratings at conditions close to your space.
Frequently asked questions
How do I set up accurate inputs for the Dehumidifier Size Calculator?
Start with the real project rather than nominal dimensions. Measure room area and ceiling height, then choose the damp-severity setting that best reflects the space. That gives the Dehumidifier Size Calculator the inputs it needs for a suggested dehumidifier extraction-capacity range from room size and damp severity.
Should I use a default value for temperature, humidity and lab ratings in the Dehumidifier Size Calculator?
Before relying on the Dehumidifier Size Calculator, check temperature, humidity and lab ratings. A dehumidifier rated at warm, humid laboratory conditions may remove much less water in a cool room. Compare ratings at conditions close to your space.
Is the Dehumidifier Size Calculator a final sizing calculation?
For the Dehumidifier Size Calculator, after calculating, use the suggested range to shortlist units, then compare extraction data at temperatures and humidity levels similar to the room. Cooler conditions can reduce real extraction markedly.
