How wide should a sideboard be?

Updated October 2026 · 3 min read · by Tuckhouse

The short answerPick a sideboard that leaves about 6 in of wall on each side and about 36 in of walkway between it and the table edge. In practice a 31.5 in cabinet fits a 44 in nook, a 55 in sideboard needs about 67 in of wall, and a 67 in credenza needs about 79 in. These are common interior design rules of thumb, not building codes; they keep the piece from looking squeezed and leave room to walk past seated guests.

Width: match it to the wall

Sideboard widthExampleWall you need (width + 12 in)
31.5 inThe Barn Door Cupboardabout 44 in
51.2 inThe Fluted Barabout 63 in
55.1 inThe Deco Sideboardabout 67 in
66.9 inThe Rattan Credenzaabout 79 in

If the sideboard sits behind a dining table, it also looks balanced when it is a little shorter than the table, so the table does not overhang it on both ends.

Depth: the number that decides small rooms

Depth is what takes space from the walkway. Add about 36 in for walking (more if chairs push back toward the sideboard) and you get the distance you need from the wall to the table edge:

If your table sits less than 48 in from the wall, a shallow 11-12 in cabinet is usually the only kind that still leaves a comfortable path.

Height: just above the table

Most sideboards stand 30-37 in tall. The 55 in carved sideboard is 33.5 in, the 67 in rattan credenza 31.5 in, the 31.5 in cupboard 31.6 in and the bar cabinet 37 in. Standard dining tables are about 30 in tall, so a 31-34 in sideboard sits just above the table, which works as a serving surface and keeps lamps and art at a natural height.

Doors, drawers or a bar cabinet?

Decide what goes inside before you decide the width. Drawers suit cutlery and table linens; the 31.5 in cupboard has 2 drawers above 2 doors. Tall doors with adjustable shelves, like the 55 in carved sideboard, take serving bowls and small appliances. If the piece will hold a coffee machine or a mini fridge, look for a bar cabinet with a deeper body and a built-in outlet, like the 51 in bar cabinet with its charging hub, and check that the outlet sits within reach of the wall socket.
