What is the recommended clearance around furniture?

Most interior designers recommend at least 24 inches (60 cm) of clear walkway around major furniture pieces. In tight spaces, 18 inches (45 cm) is the absolute minimum for a passable aisle. Traffic zones such as paths to doors or bathrooms should have at least 36 inches (90 cm).

Does the calculator account for door swings?

The current version checks room boundary clearance only. Measure your door swing radius separately (typically 28–36 inches for interior doors) and ensure the furniture placement leaves that zone clear.

Which measurement is length vs. width for a sofa?

Enter the longest horizontal dimension of the sofa as the length and the depth (front-to-back measurement) as the width. For beds, length is head-to-foot and width is side-to-side.

Can I check furniture that goes in the center of the room?

Yes. Select "Center" as the placement option. The calculator places the furniture in the middle of the room and checks clearance on all four sides.

What if my room is not rectangular?

The calculator assumes a rectangular room. For L-shaped or irregular rooms, measure the rectangular zone where the furniture will sit and use those dimensions.

Are diagonal or angled placements supported?

Not currently. The tool handles axis-aligned placements (against a wall or centered). For angled placement, use the longer diagonal dimension of the furniture as a conservative estimate.
