What size dehumidifier do I need for a basement?

Reviewers and specialist communities consistently advise oversizing rather than matching the manufacturer's square-footage claim, which is measured under extreme heat and humidity. Across r/homeowners and r/Dehumidifiers, owners report small units running nonstop while still smelling musty, and recommend a 50-pint-plus compressor unit with a drain hose for most basements up to roughly 2,500 sq. ft.
