How to Measure for Custom Curtains
Getting accurate measurements ensures your custom curtains fit perfectly. Follow this simple guide.
What You'll Need
- A metal tape measure (not fabric)
- A step stool for high windows
- Pen and paper to record measurements
Step 1: Measure the Width
Measure the width of your curtain rod (not the window). If you don't have a rod yet, measure the window width and add 4-8 inches on each side for proper coverage.
For standard coverage: Rod width = Window width + 8 to 16 inches
Step 2: Measure the Length
Measure from the top of the curtain rod to where you want the curtain to end:
- Sill length — to the window sill (casual look)
- Below sill — 4 inches below the sill (classic look)
- Floor length — ½ inch above the floor (elegant look)
- Puddle — 1-3 inches on the floor (dramatic, luxurious look)
Step 3: Understanding Fullness
Fullness refers to how much fabric gathers across your rod:
- 1x fullness — flat panel, no gathers (use if you already added extra width)
- 1.5x fullness — standard, gentle gathers
- 2x fullness — full, luxurious gathers (recommended for pinch pleat & pencil pleat)
Our custom curtain configurator handles fullness calculations automatically — just enter your rod width.
Step 4: Choose Number of Panels
Most windows use 2 panels (one on each side). For narrow windows, 1 panel may be enough. For very wide windows, consider 3-4 panels.
Tips
- Measure each window separately — they may vary slightly
- Round up to the nearest inch
- When in doubt, go slightly wider and longer
