How the calculation works
packages = ceil(required × (1 + reserve) ÷ package length)
Calculate each color or dye lot separately. Adding all colors together can undercount packages because each color must be rounded up independently. Leftover after reserve is a planning number, not measured inventory.
Full calculation methodologyWorked example
840 yd with 10% reserve needs 924 yd. Two 500 yd cones cover that, leaving 76 yd beyond the reserved requirement.
Use the complete weaving planner to connect the dimensions, allowances, and yarn quantities for one project.
