Measuring Before You Order Furniture: The Route, Not Just the Room

Furniture returns are expensive, slow, and sometimes not possible. Almost all of them come from a measurement not taken. The room is usually measured; the route into it usually is not.

Measure the route

1. The narrowest point. Walk the path from the front door to the room and find where it pinches — a doorway, a hallway corner, a stair turn. That number, not the room, is your limit.
2. Doorway width and height, measured inside the frame with the door open. Removing the door adds a few centimetres and is often the difference.
3. Stair turns. Measure the width of the landing at the turn and the ceiling height above the stairs. This is where tall items fail.
4. Ceiling height in the room, for wardrobes and shelving that must be tilted upright.

Diagonal depth, the number people miss

Sofas and armchairs are carried at an angle, so the measurement that matters is the diagonal across the depth and height, not the width. Manufacturers of larger sofas sometimes publish it. If not, measure the diagonal of the doorway and compare against the diagonal of the item.

A sofa that is too big to get in is the most common expensive furniture mistake, and it is entirely avoidable.

Flat-packed or assembled

A flat-packed wardrobe passes through doorways an assembled one cannot. If the route is tight, this alone may decide which product to buy. Check the listing, because some retailers deliver assembled by default and some offer both.

Note also that assembled goods are frequently excluded from standard returns once built, so the measuring has to happen before the assembly, not after.

In the room

• Leave walking space. Furniture that fits exactly leaves no room to use the room.
• Check door and drawer swing. A wardrobe that fits the wall but cannot open fully is a wardrobe you will resent.
• Mark it out on the floor with tape at the actual dimensions. This shows you the footprint far better than a number does.
• Check radiator, socket and window positions against the back of the item.

Delivery terms

Three different things are commonly called delivery, and the difference is significant for heavy goods:

• Kerbside — left outside. You move it.
• Threshold — inside the front door, no further.
• Room of choice — carried to where it goes, sometimes with assembly and packaging removal.

These are stated in the delivery terms rather than on the product page, and the cheapest total price often assumes the least service.

Before you order

Measure the narrowest point of the route and compare against the item's diagonal depth. Check whether the item ships flat-packed or assembled. Check which delivery service is included and whether old furniture removal is offered. And check the return terms for assembled and made-to-order goods, which are usually excluded — for those, the measurement is your only protection.
