Width and fullness decide how many panels to buy, and where the rod sits decides how long they should be.
How it works
Rod width × fullness ÷ panel width, rounded up to pairs. Length is rod height to the hem style you choose, then next stock length.
Before you order
- Mount the rod higher and wider than the window to make it feel larger.
- Hem after hanging for a few days, since some fabrics relax.
- Check clip rings: they change where the top of the panel sits.
Common questions
How wide should curtains be?
Aim for 2 to 2.5 times the rod width for a full look, and 3× for sheers.
Should curtains touch the floor?
A float of about 1/2 in looks clean. Touching looks tailored, and a puddle needs extra fabric and more care.
