Quick answer
Measure the window width, then add enough track beyond each side for light control and curtain stack-back. Also measure the required projection so the curtains clear handles, blinds, radiators and sills.
Visual planning
Start with the shape of your window.
A continuous run across the opening. Plan space at each end for the curtains to stack clear of the glass.

SECTION 01
Measure the window width
Measure the full opening and note any wall restrictions on either side. Do not assume both sides have equal space.
SECTION 02
Add side overlap
Extending the track beyond the window helps reduce light gaps and allows the curtains to stack away from the glass.
SECTION 03
Measure projection
- Window handles
- Blinds
- Radiators
- Deep sills
- Existing poles or pelmets
SECTION 04
Take useful photos
Photograph the full wall, ceiling, window head and any obstructions. Wider context is often more useful than a close-up alone.

Questions answered
Frequently asked questions
How much wider should a track be than the window?
It depends on curtain fullness and available space. The goal is to provide adequate overlap and stack-back without colliding with adjacent walls or furniture.
Do I measure the track or the window?
Start with the window, then calculate the finished track width after adding the required overlap on both sides.
Should I measure at ceiling height?
Yes, when planning a ceiling-mounted track. Wall widths and obstructions can differ at ceiling level.
