WHAT IS BASEBOARD?

Baseboard is the trim that runs along the bottom of your walls. It covers the joint between the wall and the floor, hides gaps, protects the drywall, and ties the room together visually. It’s one of the most recognizable pieces of interior trim in North America — and one of the first things people notice when it’s missing, damaged, or poorly installed.

Baseboard is simple in purpose, but it’s a major part of every trim package. It runs through every room, every hallway, every closet, every jog, every corner. That’s why calculating it properly matters.

WHY BASEBOARD EXISTS

Baseboard does three jobs:

• Covers the expansion gap between flooring and drywall

• Protects the wall from vacuums, mops, pets, and life

• Finishes the room by creating a clean visual line

It’s functional, aesthetic, and structural in its own small way.

And because it runs everywhere, it’s usually the longest trim run in the house.

STANDARD NORTH AMERICAN PRACTICE

Across Canada and the U.S., baseboard is typically sold in:

• MDF (most common)

• Finger‑Jointed Pine (FJP)

• Hemlock

• Poplar

• Quarter‑Sawn White Oak

• PVC (in wet areas)

And in standard lengths:

• 8'

-

• 16'

Longer sticks = fewer joints = cleaner installs.

Baseboard also interacts with:

• Inside corners

• Outside corners

• Scarf joints

• Transitions

• Stairs

• Closets

• Base shoe / quarter round (optional but common)

But even with all that, the math stays simple.
