Common Curtain Measurement Mistakes
Measuring for curtains may seem simple, but small mistakes can lead to panels that are too short, too narrow, or hang unevenly. This guide highlights the most frequent errors and how to avoid them.
1. Measuring Only the Window Glass
Many people measure just the width of the window glass, forgetting to account for the frame and extra coverage. Curtains that are too narrow won’t fully cover the window and can look sparse.
- Always measure from outside edge to outside edge of the desired coverage area.
- Add extra width for fullness, especially for pleated or gathered curtains.
2. Hanging the Rod at the Wrong Height
Where you mount your curtain rod affects both style and function. Too low, and the room looks smaller; too high, and the curtains may not align with furniture or radiators.
- For standard drapes, 4–6 inches above the window frame creates a taller appearance.
- Floor-to-ceiling curtains require precise measurements from the ceiling to the floor.
3. Forgetting Rod or Hardware Thickness
Curtain rods, brackets, and finials all take up space. Ignoring them can make your curtains too narrow or misaligned.
- Measure with rod and brackets installed if possible.
- Ensure pleat spacing and panel width accommodate hardware thickness.
4. Not Accounting for Fabric Fullness
Curtains that aren’t full enough can look flat and cheap. Fullness is especially important for pleated or gathered styles.
| Style | Recommended Fullness |
|---|---|
| Flat Panel | 1.5× window width |
| Pleated Drapes | 2–2.5× window width |
| Sheer Curtains | 2.5–3× window width |
5. Ignoring Pattern Repeats
If your fabric has a repeating pattern, failing to account for it can create mismatched panels.
- Measure the full length needed and add extra for pattern alignment.
- Consider how panels will line up next to each other visually.
Pro Tip: Use our Curtain Calculators to automatically factor in pattern repeats and ensure your designs align perfectly.
6. Not Double-Checking Measurements
Even experienced professionals make mistakes. Always measure twice before cutting or ordering fabric.
- Have a second person verify if possible.
- Check width, height, and fullness against your plans and hardware.
Summary
Avoid these common mistakes to ensure your curtains look custom made and hang perfectly:
- Measure beyond the window glass for full coverage.
- Hang rods at the correct height.
- Account for rod and hardware thickness.
- Add proper fabric fullness.
- Align patterns carefully.
- Double-check all measurements.
