Double Curtain Track Spacing Calculator
Estimate the distance needed between a voile or rear curtain track and the main front curtain track.
Step 1
Choose the mounting type
Step 2
Choose the front curtain heading
Step 3
Choose the rear curtain layer
Step 4
Add clearance allowances
Obstruction depth can represent a window handle, radiator projection, deep sill or another feature the rear curtain must clear.
Why double-track spacing matters
Tracks placed too close together can cause the curtain layers to rub, bunch or prevent each other from moving smoothly. Excessive spacing can create an unnecessarily deep installation.
Questions answered
Frequently asked questions
How far apart should double curtain tracks be?+
The required spacing depends on the depth of both curtain layers and their headings. Enough clearance is needed so the curtains move without rubbing.
Which track should be closest to the window?+
The voile, sheer or lighter rear layer normally sits closest to the window, with the main curtain on the front track.
Do wave curtains need more spacing?+
Wave curtains retain deeper regular folds, so they commonly need more clearance than a flatter pencil-pleat layer.
How far should the rear track be from the wall?+
It must clear handles, radiators, sills and other projections while leaving room for the rear curtain folds.
