Build saved furniture arrangements for a rectangular room using measured dimensions, positions and clearance margins. HOW IT WORKS 1. Open Furniture Fit from a rectangular room and confirm its dimensions. 2. Add furniture footprints, move or rotate them and review wall and overlap warnings. 3. Save a layout variant and share its measurement summary. Refresh the room dimensions explicitly when needed. Room notes and existing measurement workflows remain available. WHAT TO KNOW This is a two-dimensional rectangular fit check. It does not assess doors, delivery routes, structural loads, accessibility compliance or irregular rooms. Walking estimates are not a substitute for measuring critical clearances. iPhone and iPad.
