How to Measure Your Space Before Buying Furniture

Measure the room, not just the wall

The wall is only one dimension. You also need the floor space, the walkways, and the path the furniture will take into the room. A piece that fits the wall but blocks a doorway is still the wrong piece.

The five measurements

1. Wall length: the space where the piece will sit.
2. Depth: the distance from the wall to the nearest walkway or furniture.
3. Doorway width and height: the path the box must pass through.
4. Walkway clearance: at least 30 inches for main paths, 36 inches where possible.
5. Seat or table clearance: the space needed to pull out a chair or open a drawer.

Use painter's tape

Mark the footprint on the floor with painter's tape. Mark the chair pull-out zone as well. Walk around the outline for a day before you buy. This catches problems that a measuring tape misses.

Check the delivery path

Measure the front door, the hallway, the stairwell, and the turn into the room. For large pieces, check the diagonal depth of the doorway. If the box is too big, the furniture will not make it inside.

Keep a simple floor plan

Sketch the room on graph paper or use a free room planner. Mark doors, windows, radiators, and outlets. Add the furniture footprint. Leave the walkways clear. A simple plan is enough to avoid most furniture mistakes.

When in doubt, go smaller

A slightly smaller piece leaves more room for movement and is easier to move later. In a small room, the extra floor space is usually worth more than a few inches of surface.
