What Size Sideboard Do I Need?
Find the right sideboard size from your wall width, storage needs, and room layout with practical guidance for dining rooms, living rooms, and open-plan spaces.
Most sideboards work best when they leave visible wall margin and stay shallow enough for the room. A small sideboard is often 36" to 48" wide, a standard one is about 54" to 72" wide, and many are about 14" to 18" deep.

People use these names differently, but the sizing problem is the same: choose a storage piece that fits the wall, opens cleanly, and does not turn a dining or living room path into a squeeze.
Measure the wall and room
- 1Measure the wall run where the sideboard will sit.
- 2Reserve visible margin on both sides so the piece does not look wedged in.
- 3Check drawer, door, chair, and walkway clearance in front.
- 4Choose depth last if the room is narrow or the sideboard sits near a dining table.
FAQ
How wide should a sideboard be?
Many sideboards land around 54" to 72" wide, but the right width depends on the available wall and how much visible margin you can leave around the piece.
What is a standard sideboard depth?
A common sideboard depth is about 14" to 18". Deeper pieces can hold more but need more walkway clearance and can crowd dining chairs.
Can a sideboard go under a TV?
Yes, if the width, height, and depth suit the TV wall and the piece does not block traffic. Keep the sideboard visually wider than the TV or pair it with wall decor so the setup looks intentional.
