Fabric tapes might stretch, therefore use a steel tape for optimal calculations.
For best results, make sure you measure the pole or track, NOT the window recess.
You will need to measure from one end to the other.
Both tracks must be measured from one end to the other, then the resulting sizes must be added.
You will need to measure the pole between the end finials.
The drop represents the final length of a curtain, therefore you must determine where you wish for it to start and to end.
Calculate from the top of the track to make sure that it will be completely covered by the heading.
For Pencil Pleat curtains, you will need to start measuring from under the pole ring. For Eyelet heading, you will need to start measuring from the top of the pole.
Observation: For optimal results, measure the available space in multiple places and order using the smallest sizes.
A. Floor length curtains
For optimal results, allow for a distance of 10 mm (1cm) to the floor or carpet.
B. Below sill length curtains
These should end 15 cm below the window sill, for the best results.
C. Sill length curtains
This type of curtains ends around 1.3 cm above the window sill
