What Size Dehumidifier for a 2,000 Sq Ft Space?
By the WhatSize editorial team 5 min read Standards-reviewed
For a 2,000 sq ft space, you need at least a 50-pint dehumidifier. For basements, very damp conditions, or high ceilings, go with 70 pints.
Why 2,000 Sq Ft Requires 50+ Pints
A 2,000 sq ft space is roughly the size of a medium house or a very large basement. At this square footage, a 35-pint dehumidifier is insufficient for all but the driest conditions. The AHAM standard calls for 30-42 pints of daily moisture removal at moderate dampness, which means you need a unit rated for at least 50 pints under the modern standard.

When 70 Pints Is the Better Choice
- If the 2,000 sq ft space is a basement or crawlspace
- If you have high ceilings (10 ft+)
- If there are multiple moisture sources (laundry, bathroom, kitchen)
Frequently asked questions
What size dehumidifier for 2,000 sq ft?
A 50-pint Energy Star dehumidifier typically uses 400-500 watts when running. At the national average of $0.14/kWh, running 12 hours per day costs about $20-25 per month.
Will one dehumidifier cover a 2,000 sq ft house?
One dehumidifier can cover an open 2,000 sq ft space, but it won't effectively cover a multi-room house. For whole-house dehumidification, consider a whole-house dehumidifier that integrates with your HVAC system.
Should I get a dehumidifier with a pump for 2,000 sq ft?
A built-in pump is highly recommended for larger spaces. It automatically pumps collected water to a sink or drain, so you don't have to empty a heavy tank.
