Measuring for Custom Curtains: It's Easier Than You Think
Getting the right measurements is the most important step when ordering custom curtains. Don't worry — it takes about 5 minutes per window and only requires a tape measure. Here's how.
Before You Start
You'll need:
- A metal tape measure (not fabric — they stretch)
- A step stool if your windows are high
- Pen and paper to note measurements
Important: If you already have a curtain rod installed, measure the rod — not the window. If you don't have a rod yet, measure the window and follow the guidelines below.
Step 1: Measure the Width
If you have a rod:
Measure from one end of the rod to the other (bracket to bracket). This is your curtain width.
If you don't have a rod yet:
Measure the window opening width, then add:
- 4-6 inches on each side for light gap coverage
- Total: Window width + 8-12 inches = recommended rod width
Example: 40" window → 48-52" rod → order 50" wide curtains
Step 2: Measure the Length
Measure from the top of where the rod is (or will be) down to where you want the curtain to end:
- Window sill: To the sill (great for kitchens and bathrooms)
- Below sill: 4" below the sill (classic cafe look)
- Floor length: To 0.5" above the floor (most popular — elegant without dragging)
- Puddle: Add 1-3" extra to pool on the floor (dramatic, luxurious)
Header Adjustments
Different headers hang differently:
- Rod Pocket & Grommet: Measure from the top of the rod
- Tab Top: Curtain will hang about 2" below the rod
- Pinch Pleat & Pencil Pleat: Measure from the bottom of the rings/hooks to where you want the curtain to end
Step 3: Choose Number of Panels
- 1 panel: Narrow windows (under 40"), or pulling to one side
- 2 panels: Standard — one on each side (most common)
- 3-4 panels: Extra-wide windows or sliding doors
Understanding Fullness
Fullness is the ratio of fabric width to rod width. More fullness = more gathers:
- 1x fullness: Flat panel, minimal gathers. Choose this if you already accounted for extra width in your measurement.
- 1.5x fullness: Standard gathers — a nice balance of fullness and fabric use.
- 2x fullness: Full, luxurious gathers — recommended for pinch pleat and pencil pleat headers.

Common Mistakes to Avoid
- Measuring the window instead of the rod — always measure from the rod
- Forgetting side coverage — extend the rod 4-6" beyond the window on each side
- Rounding down — when in doubt, round up to the nearest inch
- Assuming all windows are the same size — measure each window individually
