Measuring a Bay Window for Curtain Tracks
Measuring a bay window can raise a few questions — especially when you’re deciding between sill-length or floor-length curtains, and whether the curtains should sit fully within the bay or extend onto the returns.
This page pulls together the most common bay window measuring situations and points you to the right guide, so you can measure with confidence (and avoid the usual “second-guessing”).
