1. What is the Curtain Sewing Calculator?

The Curtain Sewing Calculator Software helps determine the amount of fabric needed for making curtains based on window dimensions, desired fullness, and pattern repeat requirements.

2. How Does the Calculator Work?

The calculator uses software algorithms to determine fabric requirements:

Where:

• Window Width — The width of the window area to be covered
• Window Height — The height of the window area to be covered
• Fullness Ratio — Desired curtain fullness (1.5x to 2.5x window width)
• Pattern Repeat — Pattern repeat length if using patterned fabric

Explanation: The calculation accounts for fabric width needed based on desired fullness, plus additional length for hems and pattern matching if applicable.

3. Importance of Accurate Fabric Calculation

Details: Proper fabric calculation ensures you purchase enough material for your project while minimizing waste. It's especially important when working with expensive or patterned fabrics.

4. Using the Calculator

Tips: Measure your window accurately, decide on desired fullness, and check if your fabric has a pattern repeat. All values must be valid (width and height > 0).

5. Frequently Asked Questions (FAQ)

Q1: What is fullness ratio?
A: Fullness ratio determines how gathered your curtains will be. Standard is 1.5x window width, while fuller curtains use 2x or more.

Q2: Why add to the height measurement?
A: Additional height accounts for hems (typically 15cm top and bottom) and possible pattern matching.

Q3: What if my fabric has no pattern repeat?
A: Simply enter 0 for pattern repeat in the calculator.

Q4: Should I add extra fabric?
A: It's recommended to add 10-15% extra for mistakes or future repairs, especially for complex projects.

Q5: Does this work for all curtain styles?
A: This calculator works best for standard curtain panels. Specialty styles like pleated or tab-top may require adjustments.
