The Advanced Sectional Warp Yardage & Bobbin Calculator is designed for weavers working with drafts that feature uneven or intricate color patterns. By uploading your WIF file, this tool parses your warp color order and helps you determine exactly how many bobbins you'll need of each color—plus total yardage per bobbin and overall project estimates. It's perfect for sectional warping and for planning projects that go beyond simple stripes or uniform designs.

Let your loom prep match the precision of your draft.
