How long should a sideboard be in a dining room?

How long a sideboard should be in a dining room depends on the size of the space and the dimensions of the accompanying dining table. Generally, a dining table should be larger than a sideboard to ensure a balanced look. You also want to ensure that there is at least 24 inches of space between the sideboard and other furnishings to provide enough clearance for walking. On 1stDibs, explore a variety of sideboards.
