Accurate measurements are the foundation of flawless drapery installation. Whether you’re a homeowner doing it yourself or a designer preparing for a project, precision ensures your draperies fit perfectly and function beautifully. Mistakes can be costly—wasting time, money, and effort.
Use these simple steps to get it right the first time
1. Gather Your Tools
Start with the basics. Having the right tools makes the process easier and more accurate.
Essential Items: Steel measuring tape, step ladder, pencil, paper, and a level.
Optional Extras: A laser measure for added precision or a friend to assist with larger windows.
Pro Tip: Avoid cloth or retractable tapes that can stretch or sag.
2. Determine the Mount Type
Where you mount your draperies affects the look and functionality. Decide early to guide your measurements.
Inside Mount: Drapes hang inside the window frame. This creates a clean, tailored look but limits light coverage.
Outside Mount: Drapes extend beyond the frame. Ideal for maximizing light blockage or making windows appear larger.
Pro Tip: Outside mounts are more forgiving of measurement errors.
3. Measure the Width
Measure the width of the window opening or the area you want the drapery to cover.
Inside Mount: Measure across the inside edge of the frame at the top, middle, and bottom. Use the narrowest width.
Outside Mount: Extend 4-6 inches beyond the frame on each side for optimal coverage.
Pro Tip: Wider drapes create a luxurious, full look. Consider extra fabric if stacking space is needed.
4. Measure the Height
Height affects how your draperies drape and where they will start.
Inside Mount: Measure from the top of the frame to the sill or floor, depending on your style.
Outside Mount: Measure from your chosen mounting point (above the frame) to the desired length. Add 2-4 inches above the frame for a taller appearance.
Pro Tip: If you plan to use a curtain rod, account for its placement when measuring.
5. Account for Fullness
Fullness refers to the amount of fabric relative to the window width. It impacts how your draperies hang.
Standard Fullness: 2 to 2.5 times the window width.
Modern Minimalism: 1.5 times the width for a sleeker look.
Rich Elegance: 3 times the width for dramatic folds.
Pro Tip: Double-check the drapery panel width to ensure it meets your desired fullness.
6. Consider Rod and Hardware Placement
Your hardware choice affects both function and aesthetics. Decide early to avoid surprises during installation.
Rod Width: Extend rods 4-6 inches beyond the window frame on each side. This allows drapes to stack neatly without blocking light.
Height Above Window: Mount rods 4-12 inches above the frame for a taller, more elegant look.
Pro Tip: Adjustable rods provide flexibility if your measurements are slightly off.
7. Factor in Hem Allowances
Don’t forget to include extra fabric for hems and puddling.
Standard Hem: Add 2-4 inches to the length for hemming.
Puddling Effect: Add 6-12 inches for a luxurious look where draperies pool on the floor.
Pro Tip: For high-traffic areas, avoid puddling to prevent tripping or damage.
8. Test with Temporary Fixes
Before committing, test your measurements. Use temporary hooks or clips to preview how the drapes will look and hang.
Check the Length: Ensure panels don’t drag unevenly or hover above the floor awkwardly.
Test the Width: Confirm the drapes cover the window fully when closed.
Pro Tip: This step helps catch errors before installation.
9. Special Considerations for Unique Windows
Not all windows are standard. Adjust your approach for unusual shapes or features.
Bay Windows: Measure each section individually and note angles carefully.
Arched Windows: Measure the widest and tallest points. Add extra fabric for creative draping.
Floor-to-Ceiling Windows: Measure the entire height and ensure your rod or track system can handle the weight.
Pro Tip: Seek professional help for particularly complex designs.
10. Double-Check Everything
Mistakes happen when measurements are rushed or skipped. Take your time and verify all numbers.
Cross-Reference: Compare your measurements with your drapery specifications.
Repeat Key Steps: Double-check widths, heights, and allowances.
Pro Tip: Always measure twice. It saves time and money in the long run.
Common Pitfalls to Avoid
Even with careful planning, some errors are common. Here’s how to steer clear:
Using the Wrong Tape: Stick to a steel measuring tape for accuracy.
Skipping Allowances: Always account for hems, rods, and stacking space.
Rushing the Process: Take your time. Precise measurements lead to flawless results.
