Baseboards are easy to overlook until they are wrong. Too short and a room looks unfinished; too tall and they crowd the walls. The right height depends mostly on the height of your ceilings, and a little on the style of the house.
Start with the ceiling
A common rule of thumb is that baseboards should be roughly seven percent of the ceiling height. It isn’t a law, but it gets you close:
- 8-foot ceilings: baseboards around 3 to 5 inches tall.
- 9-foot ceilings: around 5 to 6 inches.
- 10-foot ceilings and higher: 6 to 8 inches, sometimes more in formal rooms.
Many new houses have 8-foot ceilings with thin, 2 to 3 inch baseboards. Moving up to 5 inches is one of the cheapest ways to make those rooms look more finished.
Match the rest of the trim
Baseboards shouldn’t be read on their own. They sit in the same room as door casing, window casing, and sometimes crown moulding, and the pieces should look like they belong together. As a rough guide, casing is often about half the height of the baseboard, and crown moulding a similar size to the baseboard in the same room.
Consider the style
Simple, square-edged boards suit modern interiors. Profiles with a cap or a curved top suit traditional houses. In older homes, it is often worth matching the original profile in rooms that still have it, so new and old trim look consistent.
Think about the floor
If your floors are uneven or you are installing new flooring, plan for shoe moulding, a small strip along the bottom of the baseboard that covers gaps. It adds a little height visually, too.
