Crawl Space Dehumidifier Sizing

How to calculate the square footage of the crawl space for dehumidifier?

To calculate the square footage of your crawl space for sizing a dehumidifier, you'll need to measure the length and width of the space and multiply those numbers together. Here are the steps to follow:

Measure the length and width of the crawl space: Use a tape measure to measure the length and width of the crawl space. Measure the longest point for the length and the widest point for the width.

Multiply the length by the width: Multiply the length and width measurements together to get the total square footage of the crawl space. For example, if your crawl space is 20 feet long and 10 feet wide, the total square footage would be 200 square feet (20 x 10 = 200).

Adjust for height: If your crawl space has varying heights, you may need to adjust the square footage calculation accordingly. Multiply the total square footage by the average height of the crawl space to get the total cubic footage. Then, divide the total cubic footage by 2 to get the recommended pint capacity for your crawl space dehumidifier.

For example, if your crawl space has an average height of 4 feet and a total square footage of 200 square feet, the total cubic footage would be 800 cubic feet (200 x 4 = 800). Divide 800 by 2 to get a recommended pint capacity of 400 for your dehumidifier.

Keep in mind that other factors may affect the size of the dehumidifier you need, such as local climate, ventilation, and the amount of moisture in the crawl space. It's always a good idea to consult with a professional to determine the appropriate size for your specific needs.
