Curtains that fit on the first try.
The size on a curtain packet tells only part of the story. Work from the span your curtains must cover, the fullness you like and the way your heading hangs.

The field guides
- Guide 01
How many curtain panels do you need for an 80-inch rod?
Work from the length the panels must cover, choose a fullness, and check what standard panel widths actually give you.
- Guide 02
Does curtain width on the packet mean one panel or the pair?
Decode panel quantity, individual width and finished pleat width before converting a listing into actual fabric coverage.
- Guide 03
Where do you measure curtain length with rings or clips?
Find the top-of-fabric reference on your actual hardware, compare three floor measurements, and choose a hem clearance.
- Guide 04
Will the curtains you already own fit a wider rod?
Compare one pair on 60- and 72-inch rods, estimate how much fold each side loses, and mock up the change before moving the brackets.
- Guide 05
How far should a curtain rod extend to leave the glass clear?
Measure a gathered panel on its rings, map the working endpoints on each wall, and calculate how much glass a tight corner will cover.
