How to Use This Calculator

Enter the project width in inches and the warp sett (ends per inch, EPI).
Enter the project length in inches and the weft sett (picks per inch, PPI).
Set the warp color repeat — for example, 2 for ABAB alternating, 4 for AABB blocks.
Set the weft color repeat and the percentage of color A in both warp and weft.
Read the total pattern blocks and repeat width/height to visualize how the color-and-weave effect tiles across the fabric.
Use the color A total percentage to plan yarn quantities for each color.
