Always measure with a metal rule - cloth or plastic tapes can stretch. As a guide, tracks should be fixed at 10cm (4") above the lintel, and poles at 15cm (6").
Measure the track or pole (A) not the window. The track or pole should usually extend beyond each side of your window (15-20cm / 6-8") to enable the curtains to be pulled well back during the day.
There are 3 basic lengths to choose from :
- Sill length (B)
- Below Sill (C)
- Floor length (D)
Curtains should finish
- 0.65cm (¼") above the sill
- 15cm (6") below the sill
- 0.65cm (¼") from the floor
Measure from the point where you wish the top of the curtain to be, down to the required finished length.
If the blind is to fit inside a window recess, please provide the exact recess width (G) and drop (H) measurements. (Blinds are made 1.3cm (0.5") smaller to accommodate movement during operation)
Please provide track width (I) and not the window width. The track should extend 5cm (2") each side of the window and be fixed 10cm (4") above. The drop length (J) should be from the top of the track to the bottom of the blind when lowered usually 5cm (2") below the sill.
