What size will look right?
| Bedroom size | Starting width |
|---|---|
| 10 × 10 ft 3.0 × 3.0 m | 20 in / 51 cm |
| 12 × 12 ft 3.7 × 3.7 m | 24 in / 61 cm |
| 12 × 14 ft 3.7 × 4.3 m | 26 in / 66 cm |
Use the size chart above, then mark a candidate's actual width with tape or cardboard. View it from the doorway and bed: dense shades can look larger than open frames of the same width.
How are these sizes estimated?
Room length (ft) + room width (ft) ≈ starting fixture width (in)
A styling shortcut, not a unit conversion or a guarantee of fit. Use feet for the room and inches for the light. Metric table values are rounded.
