L- and U-shaped sofa sizes, and will it get through the door?
An L-shape is the largest piece that will come into your home, and its problems usually show up twice: when it goes into the room, and when it has to come through the door. These numbers settle both before you order.
Both shapes drawn to scale at the largest size in each range. The bar below is one metre.
The numbers at a glance
The L-shape
The long side runs 241 to 305 cm, the short side 152 to 216 cm, and the depth 91 to 102 cm. It needs a room of about 3.7 × 3.7 m or more.[1] Still deciding between an L-shape and a sofa with armchairs? “An L-shape, or a sofa and armchairs?” has five questions that give you the fit.
The U-shape
Its back runs 244 to 366 cm, each side 152 to 213 cm, and the depth 91 to 102 cm.[2] It needs a large room, about 4.6 × 5.5 m or more, with a 76 to 91 cm walkway on the open side.[1][3] Most arrive in 4 to 6 sections assembled in the home.[3]
The chaise
The chaise is the part you stretch your legs along, 152 to 183 cm long.[1][2] Put it on the side away from the room’s door and the path you walk, so it doesn’t close the way in.
Will it get through the door?
The rule is simple: the door must be wider than at least one of three measurements of the piece, its depth, its height or its diagonal depth. If any one of them is smaller than the door’s width, the piece goes through when tilted.[4]
The measurement that matters is the narrowest point on the whole route, not just the front door: the lift, the room’s door and the turn of the stairs.[4] Measure doors with and without their trim. At a corner, the piece’s width and depth must both be smaller than the distance from the corner to the facing wall for it to turn.[6]
Will it get through the door?
Type the narrowest door on the way in and the piece’s measurements from its page. The rule: the door must be wider than at least one of the piece’s depth, height or diagonal depth.
Diagonal depth: lay a straight edge from the top of the back to the front of the arm, then measure from the bottom back corner to the middle of that edge.
It won’t pass as one piece. Ask how many sections it comes in, or whether the door can come off its hinges.
Send these measurements to sales on WhatsAppA standard interior door is about 81 cm wide and 203 cm high,[5] but measure your own, because doors vary. Taking a door off its hinges gains some space, but it is not always enough.[6]
