Choose a size for your seating area
Room length (ft) + room width (ft) ≈ starting fixture width (in)
| Separate room size | Starting width |
|---|---|
| 12 × 14 ft | 26 in / 66 cm |
| 14 × 16 ft | 30 in / 76 cm |
| 16 × 18 ft | 34 in / 86 cm |
Use this rule for a defined room. In an open-plan space, judge the seating zone separately and test the outline against your furniture. Metric equivalent: (length in m + width in m) × 8.33 ≈ width in cm.
