401 Stitch Thread Usage Guidelines

Mathematical formula for determining thread usage for each line of stitching.
4 + [ 2 x (thickness of seam) x (1 / length of 1 stitch)] =  inches of thread use per inch seam
Guidelines for estimating thread usage for each line of stitching
Light weight fabric - 4 yards of thread for each yard sewn
Medium weight fabric - 6 yards of thread for each yard sewn
Heavy weight fabric - 9 yards of thread for each yard sewn
Linear Travel
Matching RPM / (RPM Stitches per inch x 12 Inches per foot) = Feet per minute
 
Example
800 RPM / (5 Stitches per inch x 12 Inches per foot) = 15 Feet per minute
