Understanding Curtain Measurements

Before we start calculating, it’s important to understand the key measurements:

  • Window width: The horizontal measurement of your window
  • Curtain width: The total width of your curtains when hung
  • Curtain length: The vertical measurement from the rod to where you want the curtains to end
  • Rod length: The length of your curtain rod, usually extending beyond the window frame

Step-by-Step Guide to Measuring for Curtains

1. Measure Your Window Width

Use a metal tape measure for accuracy. Measure the width of your window from one side of the frame to the other. If you’re using an inside mount, measure inside the window frame. For outside mounts, measure from the outer edges of the trim.

2. Determine Curtain Fullness

Curtain fullness refers to how gathered or pleated your curtains will look when closed. Here are common fullness ratios:

  • 1.5x fullness: Casual, relaxed look
  • 2x fullness: Standard, most common
  • 2.5x fullness: Luxurious, formal appearance

To calculate curtain width, multiply your window width by your chosen fullness factor.

3. Measure for Curtain Length

Decide where you want your curtains to fall:

  • Sill: To the window sill
  • Below sill: 4-6 inches below the sill
  • Floor length: 1/2 inch above the floor
  • Puddle: 1-3 inches of fabric resting on the floor

Measure from the rod to your desired endpoint.

4. Consider Rod Length

Your curtain rod should extend 3-6 inches beyond each side of the window frame. This allows curtains to be pulled back without blocking light.

Tips for Perfect Curtains

  • For wide windows, consider using multiple panels for easier operation
  • Add 4 inches to your length measurement if using ring clips
  • Remember to account for hem allowance if you’re making custom curtains

Curtain Styles and Their Impact on Sizing

Different curtain styles may require slight adjustments to your measurements:

  • Rod pocket: Add extra length to account for the pocket
  • Grommet: Ensure the rod diameter fits the grommets
  • Pinch pleat: These come pre-pleated, so follow the manufacturer’s fullness recommendations
  • Tab top: Add the length of the tabs to your overall curtain length

Frequently Asked Questions

How do I measure for bay windows?

Treat each section of a bay window as a separate window. Measure each section individually and use separate rods for a custom fit.

What if my windows are different sizes?

Measure each window separately. For a cohesive look, you may want to use the largest size for all windows in the same room.

Should curtains touch the floor?

It's a matter of personal preference. Floor-length curtains are popular for a polished look, but you can also choose shorter lengths for functional spaces like kitchens.

How do I calculate curtain rod length?

Add 6-12 inches to your window width to allow for overlap when curtains are open.

Can I use the same calculations for sheer curtains?

Sheer curtains often require more fullness. Consider using a 3x fullness factor for a luxurious, gathered look.
