Curtain Guides: The Complete Library

Every guide below is written by the Sill Shade workroom team from 60+ years of measuring, sewing, and installing window treatments. Start with the topic you need — each guide stands alone, and together they cover the complete process of choosing, measuring, and hanging curtains.

Measuring & Length

Get the numbers right before you buy anything. These three guides settle the questions we hear most in the shop.

Hanging & Hardware

Where the rod goes matters more than what hangs on it.

Styles, Fabrics & Light Control

What the curtain is made of decides how the room feels — and how well you sleep.

By Room

Every room asks a different question of a curtain. Start here if you know the room but not the answer.

Tricky Windows & Special Situations

The windows that don’t follow the standard rules — and the workroom solutions for each.


New guides are added regularly. Can’t find your situation? Our contact page is open — real questions from readers often become our next guide.

Working the hard side of the window instead? Blinds, shades, and the measuring routine for them live in our blinds & shades guides.
