Choosing beautiful curtains is easy but getting the right fit is what truly makes your windows look elegant and professionally styled. Many people eyeball the size and end up with curtains that are too short, too narrow, or poorly positioned.
The good news is that measuring for curtains is simple when you know what to look for. Here’s a clear, step-by-step guide to help you measure any window perfectly.
1. Measure the Curtain Rod Width (Not the Window)
Most people make the mistake of measuring the window frame. Instead, you should measure the curtain rod, since curtains hang beyond the window to make it look larger.
How to do it:
-
Measure the full rod width from end to end.
-
If you plan to install a new rod, extend it 4–6 inches beyond each side of the window.
-
This gives your window a wider, more open appearance.
💡 Pro tip: Extending the rod also helps block side light for bedrooms.
2. Decide on the Curtain Fullness
Fullness creates the soft, flowing look that makes curtains feel luxurious rather than flat.
Here’s the standard fullness calculation:
-
Standard Look: Curtain width = 2 times the rod width
-
Luxe Look: Curtain width = 2.5–3 times the rod width
-
Sheers: Curtain width = 3 times the rod width
Example:
If your rod is 50 inches wide, your curtains should be 100–150 inches total width.

3. Measure the Curtain Length
You have three main length styles to choose from, depending on the look you want:
A. Sill Length
Curtains fall right at or just above the window sill.
✔ Best for kitchens and small windows.
B. Floor Length
Curtains graze the floor lightly.
✔ Clean, modern, and elegant.
✔ Perfect for living rooms and bedrooms.
C. Puddle Length
Curtains extend 2–4 inches onto the floor.
✔ Luxe, romantic, and great for formal spaces.
How to measure:
-
Measure from the top of the rod to your desired end point (sill, floor, or puddle).
-
For grommet or tab-top curtains, measure from the top of the rod to the floor.
-
For rod-pocket curtains, measure from the pocket seam to the floor.
4. Measure Rod Height and Placement
Curtains look best when hung higher than the window frame.
The sweet spot is usually:
✔ 4–6 inches above the top of the window
or
✔ Close to the ceiling for dramatic height
This makes your ceilings appear taller and your space more open.
5. Accounting for Curtain Styles
Different curtain styles hang differently, so your measurements must adjust accordingly.
Grommet Curtains
-
Hang lower because the rod passes through the holes
-
Add 1–1.5 inches to compensate
Rod Pocket Curtains
-
The fabric sits on the rod
-
Measure to the pocket seam, not the fabric top
Tab Top Curtains
-
Tabs add extra height
-
Subtract 1–2 inches from total length

6. Double Check Everything Before Buying
Before placing your order, confirm:
-
Rod width
-
Desired fullness
-
Exact length
-
Mounting height
-
Curtain style (grommet, panel, rod pocket)
One quick double-check saves you from returns and ensures a professional, polished look.
