Fabric Calculation Formula:
| From: | To: |
The Pillow Fabric Calculator With Repeat helps calculate the exact amount of fabric needed for pillow projects, accounting for pattern repeats to ensure proper pattern alignment and minimal fabric waste.
The calculator uses the fabric calculation formula:
Where:
Explanation: The formula accounts for the additional fabric needed to match patterns across multiple pillow pieces, ensuring consistent design alignment.
Details: Proper pattern repeat calculation is essential for achieving professional-looking results in sewing and upholstery projects, preventing pattern mismatches and reducing fabric waste.
Tips: Enter pillow size in inches, pattern repeat length in inches, number of pieces needed, and fabric width in inches. All values must be positive numbers.
Q1: Why is pattern repeat important in fabric calculation?
A: Pattern repeat ensures that patterns align correctly across multiple pieces, creating a cohesive and professional appearance in the final product.
Q2: What if my fabric has no pattern repeat?
A: If there's no pattern to match, you can enter 0 for the repeat value, and the calculator will compute yardage based on size alone.
Q3: How do I measure pattern repeat?
A: Pattern repeat is measured from one point in the pattern to the exact same point in the next repetition, typically along the length of the fabric.
Q4: Should I add extra fabric for seams?
A: This calculator provides the exact pattern-matched yardage. You may need to add additional fabric for seam allowances depending on your project requirements.
Q5: Can this calculator be used for other sewing projects?
A: While designed for pillows, the formula can be adapted for any project requiring pattern matching, such as curtains, bedding, or clothing.
