Yardage & WOF Strip Math

Block Fabric Area Math: Converts geometric patch fractions of finished blocks into total square inches, applying a 15% safety buffer for seam loss and trimming.

WOF Strip Conversion: $\text{Strips} = \lceil \frac{\text{Required Sq Inches}}{\text{Usable WOF} \times \text{Strip Width}} \rceil$. Usable WOF assumes 40" per bolt strip after trimming 1" selvages from both edges.

Quarter-Yard Purchasing Rounding: All final yardage amounts round up to the nearest 1/4 yard ($0.25$ yd) to match standard quilt shop cuts.

Why & When to Use This Tool

• Complete Project Shopping List: Calculate exact yardage requirements for blocks, sashing, borders, backing, binding, and batting in one unified list.

• Prevent Mid-Project Fabric Shortages: Quilt fabric dye lots vary between bolts. Calculating complete yardage up front ensures consistent fabric color.

• Pattern Storage Integration: Automatically syncs with designs created in the Pattern Maker to calculate exact custom pattern yardage.
