Measure your window opening
Use a metal tape measure for accuracy. Measure the window frame opening — not the glass.

Single panel

Four panels
For most standard windows, 2 panels is the right choice.
How will you hang them?
Where you place the rod changes the final curtain length. Ceiling mount makes rooms feel taller.
Ceiling / High Mount
Rod placed 4–6" from ceiling. Recommended by Helen.
Above Frame
Rod placed 4–8" above the window frame.
Rod Height from Floor (optional)
inches
Helen's rule: hang your rod as close to the ceiling as possible.
Choose your fullness
Fullness is how much fabric you have relative to your window width. More fabric = more luxurious drape.
Light & Minimal
1.5× fullness. Flat, contemporary.
Classic Full
2× fullness. Most popular. Recommended.
Luxurious
2.5× fullness. Hotel-style plush drape.
Curtain Length Style
Just touching floor
Clean, modern
Slight puddle (+2")
Romantic, soft
Floating (−½")
Practical, neat
