That’s where the Curtain Fabric Calculator comes to your rescue. Here, we’ll walk you through how to use the calculator and explain its formula, making choosing your curtain fabric a breeze.
Understanding curtain size calculator
Curtains aren’t just flat sheets of fabric that you hang on a pole or track. The amount of fabric you need depends on the curtain’s “fullness,” which determines how gathered or tailored the curtains will look when hung. Fullness is often determined by the curtain heading type you choose. Here’s a rundown of the recommended fullness for different heading types:
- Pencil Pleat / Gathered / Stand Up / Floppy Top: 2 times fullness (6″ pencil pleat tape can be 2.5 for extra fullness)
- Eyelet / Tab Top: 2 times fullness
- Double Pinch Pleat: 2.3 times fullness
- Triple Pinch Pleat: 2.5 times fullness
- Wave: 2.3 times fullness
Now that you understand the concept of fullness and heading types, let’s dive into how to use the Fabric Calculator for Curtains.

How to Use Our Curtain Fabric Calculator
- Measure Pole/Track Width: Start by measuring the width of your curtain pole or track. This measurement will serve as the basis for calculating the fabric needed.
- Choose Fullness and Calculate Total Width: Select the appropriate fullness for your curtain heading type from the list above. Multiply the pole width by the chosen fullness. For example, if your pole width is 150cm and you’re using pencil pleat heading (2 times fullness), the total width would be 150cm * 2 = 300cm.
- Calculate the Number of Widths: Divide the total width by the fabric width, which is typically 137cm. Round up the result to the nearest whole number. For instance, if your total width is 300cm and the fabric width is 137cm, the calculation would be 300cm / 137cm ≈ 2.19, rounded up to 3. This means you need 3 widths of fabric.
- Determine Fabric Needed: Finally, multiply the drop measurement (curtain length) by the number of widths needed. This will give you the total amount of fabric to order. For example, if your drop is 175cm and you need 3 widths, the fabric needed would be 175cm * 3 = 525cm, which is equivalent to 5.25 meters of fabric.

Calculation for Patterned Fabric
If you’re opting for patterned fabric, there’s an additional consideration. You’ll need to account for extra fabric to match the pattern. Here’s how to do it:
- Calculate Total Drop: Add the curtain drop (length) and the hem allowance for the chosen heading. For instance, if your curtain drop is 220cm and the hem allowance is 25cm (for pencil pleat), the total drop would be 220cm + 25cm = 245cm.
- Pattern Repeat Calculation: Divide the total drop by the pattern repeat size. Round up the result to determine how many pattern repeats you need. For example, if the pattern repeat is 64cm, the calculation would be 245cm / 64cm ≈ 3.82, rounded up to 4. This means you need 4 pattern repeats.
- Calculate Extra Fabric: Multiply the number of pattern repeats by the pattern repeat size. In this example, it would be 4 * 64cm = 256cm. This is the additional fabric needed for the pattern match.
By following these steps, you’ll understand how much fabric you need for your curtains, whether they’re plain or patterned. The Curtain Fabric Calculator simplifies the process, ensuring you make the right choices when purchasing fabric for your window treatments.

Fullness determines how gathered or tailored your curtains will look. It’s influenced by the heading type, such as pencil pleat, eyelet, or pinch pleat.
Measure your pole or track width, choose fullness based on heading type, calculate the total width (pole width multiplied by fullness), determine the number of fabric widths needed, and multiply the drop by the number of widths for the total fabric needed.
If your pole width is 150cm and you’re using a pencil pleat (2 times fullness), the total width would be 150cm * 2 = 300cm. If the fabric width is 137cm, you’d need 3 widths for a total fabric length of 525cm (drop of 175cm multiplied by 3).
Calculate the total drop by adding the curtain drop and hem allowance. Consider the pattern repeat size, divide the total drop by it, round up to determine the pattern repeats needed, and multiply by the repeat size to find the extra fabric needed for the pattern match.
Pattern repeat ensures that the design matches seamlessly across the curtain. Calculating it helps determine the additional fabric required for a uniform pattern appearance.
Multiply the number of pattern repeats by the pattern repeat size. This gives you the additional fabric to maintain a consistent pattern across your curtains.
Yes, the calculator accommodates various heading types, including pencil pleats, eyelets, pinch pleats, and more. Choose the appropriate fullness based on your heading type for accurate measurements.
Yes, the calculator works for both. For patterned fabrics, follow the additional steps to account for the pattern repeat and ensure a cohesive design.
Conclusion
In conclusion, the Curtain Fabric Calculator takes the guesswork out of fabric calculations for curtains. With a few simple measurements and calculations, you can confidently order the perfect amount of fabric for your curtains, whether you’re going for a tailored or gathered look and whether your fabric is plain or patterned. Say goodbye to overestimating or underestimating fabric needs – the calculator has you covered!
