How to Use This Calculator
- Enter total seam length (inches) and select stitch type (straight, zigzag, or overlock).
- Review thread consumption in yards and meters.
- Check spools and cones needed based on standard thread spool sizes.
- Buy 20% more thread than calculated -- tension adjustments and practice seams consume thread.
- A 4-thread overlock uses ~4x more thread than a straight stitch -- plan accordingly.
