Standard Furniture Dimensions: Sizes, Heights and Clearances by Room

Standard furniture dimensions chart

The ranges below cover the bulk of what US and European retailers sell. Width is side to side as you face the piece, depth is front to back, and height is floor to the highest point. Pieces outside these ranges exist, but they are sold as "apartment", "oversized" or "counter height" versions and say so in the listing.

Each of these has its own guide with style-by-style sizes: sofas and sectionals, armchairs, recliners, ottomans, coffee tables and bean bag chairs. For the stand under the TV, see TV stand sizes.

Seating capacity by shape, room size and leaf extensions are in the dining table size guide. Chair seat widths and spacing are in the dining chair guide, and stool heights for kitchen islands are in the bar stool guide. For every other kind of table, from consoles to folding banquet tables, see table sizes.

Bed frames add to the mattress footprint, and headboards add more. The bed frame guide and mattress size chart have the full numbers, and bedroom furniture dimensions covers dressers, nightstands and wardrobes in detail. Office pieces are in the desk and office chair guides.

The height standards that tie furniture together

Furniture heights are not arbitrary. They are set relative to the human sitting position, so pieces from different brands still work together. If you remember one number, make it the 10-12 in (25-30 cm) gap between a seat and the surface in front of it.

This is why a "counter stool" bought for a 42 in bar leaves your knees far below the counter, and why a lounge chair with a 15-16 in seat feels low at a 30 in desk. Check the pair, not the piece.

Clearances: how much space to leave around furniture

Furniture that fits the floor plan on paper can still make a room unusable. These are the working distances designers use, including the NKBA kitchen planning figures for seating areas.

What fits in common room sizes

Add the furniture depths and the clearances in a line across the room. The worked examples below use the mid-range sizes from the charts above.

Living room, 12 × 15 ft (366 × 457 cm)

Across the 12 ft (144 in) width: a 36 in deep sofa, 16 in to a 24 in deep coffee table, 16 in to a pair of 32 in deep armchairs. That totals 124 in, leaving 20 in behind the chairs, which is not enough for a walkway. Either push the sofa against the wall and route traffic along the 15 ft side, or swap the armchairs for a 20 in deep bench or ottoman. An 84 in sofa leaves 96 in of the 15 ft (180 in) length for end tables and a walkway.

Dining room, 10 × 12 ft (305 × 366 cm)

Subtract 36 in on every side for chairs and passage. That leaves a table zone of 48 × 72 in. A 36 × 60 in table (6 seats) fits with room to spare, and a 40 × 72 in table fits exactly. A 42 in round table also works and seats four comfortably.

Bedroom, 10 × 12 ft (305 × 366 cm)

A queen bed (60 × 80 in mattress, about 64 × 86 in with a frame and headboard) against the 10 ft wall leaves 56 in of width, or 28 in per side. That clears the 24 in minimum and takes nightstands up to about 24 in wide. With 58 in left at the foot, a 18 in deep dresser still leaves 40 in to open its drawers. A king (about 80 in wide with a frame) would leave only 20 in per side, below the minimum, so a 10 × 12 ft room is the practical limit for a queen.

Getting furniture through doors, halls and stairs

Most delivery failures happen at the front door, not in the room. Measure the whole route before you order anything bulky.

1. Measure the clear width of every door. Measure between the door stop and the open door face, not the door slab. A 36 in exterior door gives about 33-34 in clear, a 32 in interior door about 29-30 in, and a 30 in door about 27-28 in. Taking a door off its hinges gains roughly 1.5-2 in.
2. Compare with the piece's smallest two dimensions. A sofa usually goes through on its back or on end, so its height and depth matter more than its length. If either is smaller than the door's clear width, it can fit.
3. Check hallway turns. A long piece turning from a 36 in hall into a 30 in door needs far more space than either opening alone. Long sofas often fail here.
4. Check stair headroom and landings. Measure the ceiling height above the stairs and the width and depth of any landing where the piece must turn.

Sofas, sectionals and recliners have their own delivery measurements (diagonal depth, removable backs and legs), covered in the sofa guide. Standard door widths are listed in the door size guide.

Children's and outdoor furniture

Children's furniture scales the same 10-12 in seat-to-table gap down to a child's leg length. Outdoor furniture keeps indoor dining heights but lowers and deepens lounge seats.

Children of the same age vary widely in height, so the child's own leg length is a better guide than age: the seat is right when their feet rest flat and thighs are level. Size marks by height and the European school furniture standard are in the kids furniture guide and the kids table guide.

Outdoor dining sets use the same 28-30 in table and 17-19 in seat heights as indoor sets. Deep-seating outdoor sofas and lounge chairs are lower (seat about 14-17 in) and deeper (30-40 in overall) to suit cushions and reclining. The outdoor furniture and patio furniture guides cover sets, loungers and how much patio area each needs.

Measuring furniture correctly

• Width: at the widest point, usually across the arms of a sofa or chair, or the top of a table including any overhang.
• Depth: from the front of the seat or arm to the back, including back cushions and any back legs that splay out.
• Height: floor to the highest point, including back cushions or a headboard.
• Seat height: floor to the top of the seat cushion at the front, uncompressed. Expect a soft cushion to sink 1-2 in when sat on.
• Product listings: retailers usually list W × D × H in that order. A listing that gives three numbers without labels should be checked against the photo, because some brands list D × W × H.
