A well-measured curtain rod can transform the look and function of your window treatments. This curtain rod measurement guide shows you how to measure window width and placement for curtain rods that fit perfectly and complement your curtains.
What You’ll Need:
Tape measure
Pencil and notepad
Ladder or step stool (for higher windows)
Step 1: Measure the Width of the Window
Measure the width of the window frame.
Add 15–30 cm on both sides for curtain stack-back and overlap.
Step 2: Decide Rod Placement Height
Standard placement is 10–15 cm above the window frame.
Measure from where you want to mount the brackets down to the window sill or floor, depending on curtain length.
Step 3: Choose Rod Length
Add the extra width from Step 1 to get the total rod length.
Ensure the rod extends far enough for curtains to fully clear the window when open.
Tips for Curtain Rod Measurement
Measure twice before purchasing.
Consider decorative finials when measuring total rod length.
Check weight limits of rods if using heavy curtains.
