Measuring Basics

Inside Mount vs Outside Mount Curtains

Understand the difference between inside and outside mount curtains before measuring rod width and panel length.

Inside mount curtains fit within the window frame, while outside mount curtains hang on the wall or trim around the window. The choice changes the rod width, curtain length, and amount of light coverage.

Inside Mount

• Cleaner and more contained look.
• Works best when the frame has enough depth.
• Usually uses the exact inside opening width.

Outside Mount

• More common for full-size curtains.
• Can make a window appear larger.
• Needs extra rod width beyond both sides of the window.
