Baseboard Heater - Up to 25 sq. ft.
What is the smallest electric baseboard heater?
The smallest standard electric baseboard heaters are roughly 2 feet (24 inches) long. Compact baseboard heaters are available in short lengths and low wattages for small rooms with limited wall space. Exact dimensions vary by manufacturer, so compare heater length, wattage, voltage, and clearance requirements.
How do I choose a compact baseboard heater?
Measure the available wall space first, then determine the wattage required for the room. To do so, find the room's square footage by multiplying its Length by its Width (L x W = Sq.ft).
Once the square footage is determined, multiply the square footage by 10W to find heating requirements for standard insulation.
- Square feet x 10 = Target Heater Wattage (assuming adequate insulation)
Most compact baseboards start at 24 inches long and provide roughly 375 to 750W of heat. The heater must fit the installation space and meet the room's heating needs. For a full breakdown of calculating required heat, see our Baseboard Heater Sizing Guide.
