How to Calculate Curtain Fabric with Pattern Repeat
When it comes to measuring and purchasing curtain fabric, especially when the pattern has a repeat, it can be quite challenging. The pattern repeat refers to the distance between the beginning and the end of the design on the fabric. It is crucial to accurately calculate the amount of fabric needed to ensure that the pattern aligns seamlessly across the curtains. In this article, we will guide you through the process of how to calculate curtain fabric with pattern repeat.
Firstly, it is essential to determine the pattern repeat of the fabric. This information can usually be found on the fabric’s label or by contacting the manufacturer. The pattern repeat is typically measured in inches or centimeters and is represented by two numbers, such as 8×8, which means the design repeats every 8 inches both horizontally and vertically.
Once you have the pattern repeat, you need to measure the width and length of the window or the area where the curtains will be hung. Ensure that you measure from the top of the window to the desired curtain length, including any additional length for the rod pocket or header.
Next, divide the window width by the pattern repeat width to determine how many times the pattern will fit across the window. For example, if the window width is 96 inches and the pattern repeat is 8 inches, the pattern will fit 12 times across the window.
Now, consider the pattern repeat’s vertical aspect. Multiply the number of times the pattern fits across the window by the pattern repeat’s vertical measurement to calculate the vertical repeat. In our example, 12 times 8 inches equals 96 inches. This means the pattern will repeat 12 times vertically.
To calculate the total fabric length, add the desired curtain length to the height of the pattern repeat. For instance, if you want the curtains to be 84 inches long, add 96 inches (the vertical repeat) to 84 inches, resulting in a total of 180 inches of fabric.
Finally, multiply the total fabric length by the window width to determine the amount of fabric needed. In our example, 180 inches by 96 inches equals 17,280 square inches. To convert this to yards, divide by 36 (since there are 36 inches in a yard), resulting in approximately 483.33 yards of fabric.
Remember to add a little extra fabric for unforeseen circumstances or for a more comfortable fit. It is always better to have a little more fabric than to run short.
In conclusion, calculating curtain fabric with a pattern repeat requires careful measurement and consideration of the pattern’s repeat. By following these steps, you can ensure that your curtains will have a seamless and attractive pattern. Happy curtain shopping!
