Speaker Room Size Calculator

To choose speakers based on room size, consider room volume. Roughly match speaker wattage to the room’s cubic feet. Small rooms (up to 2,000 cu ft) may need 100-200 watts, medium rooms (2,000-5,000 cu ft) 200-500 watts, large rooms (5,000-10,000 cu ft) 500-1000 watts, and very large rooms (10,000+ cu ft) 1000+ watts.

Room Size (Cubic Feet)	Recommended Speaker Wattage (Watts)
Small Room (up to 2,000 cu ft)	100 – 200 Watts per channel
Medium Room (2,000 – 5,000 cu ft)	200 – 500 Watts per channel
Large Room (5,000 – 10,000 cu ft)	500 – 1000 Watts per channel
Very Large Room (10,000+ cu ft)	1000+ Watts per channel

FAQs

How do I match my room size to speakers? To match room size to speakers, consider the room’s cubic footage. A rough estimate is to choose speakers with a power rating (in watts) that matches the room’s cubic footage (e.g., a 20x20x10 ft room, or 4,000 cubic ft, would benefit from speakers with at least 4,000 watts).
