The Window Curtain Panel Calculator helps determine how many curtain panels you need to cover a window based on the window width and the width of individual curtain panels.
The calculator uses a simple formula:
Where:
Explanation: This calculation gives you the minimum number of panels needed to cover your window. You may want to round up for better coverage.
Details: Calculating the correct number of panels ensures your window is properly covered, maintains aesthetic proportions, and helps with budgeting for your window treatments.
Tips: Measure your window width accurately from frame to frame. Know the exact width of the curtain panels you plan to use. Remember that some fullness (1.5-3 times the window width) is often recommended for a luxurious look.
Q1: Should I round up the number of panels?
A: Yes, it's generally recommended to round up to the nearest whole number for better coverage and a fuller look.
Q2: How much fullness should I aim for?
A: For standard curtains, 2-2.5 times the window width is common. For sheer curtains, 2.5-3 times is recommended.
Q3: Should I measure the window or the rod?
A: Measure the width of the area you want to cover - typically the curtain rod width, which is often wider than the window itself.
Q4: What if my panels have grommets or pleats?
A: The calculation remains the same, but remember that pleated panels will have less flat width when hung due to the pleating.
Q5: How do I account for overlapping panels in the middle?
A: Add 4-6 inches to your total width calculation to account for the overlap where panels meet in the center.
