Baseboard stops at each doorway. Count them to subtract what you don't need and get stick lengths to buy.

How it works

Perimeter minus doorway widths, plus 10%, divided by stick length.

Before you order

  • Cope inside corners when the walls are out of square.
  • Scarf joints on long walls so seams stay tight.
  • Prime or paint sticks before installing to save caulk and touch-up time.

Common questions

Should I subtract closet doorways?

Yes, if there is no base there. But buy for the closet interior walls if you'll run baseboard inside them.

What size sticks should I buy?

Longer sticks mean fewer joints but are harder to transport. Choose the longest you can carry safely.
