Tip: If the hook and loop sides are different widths or materials price them separately by running the calculation twice.
Notions Velcro Length is the total length of hook and loop tape needed for a closure or strap in sewing projects It includes the path of the closure plus overlap allowances extra tails and waste The length may be calculated per piece and then multiplied by quantity to plan purchasing and budgeting for accurate inventory control cutting layouts and results
Overlap is the portion where the two sides of the tape meet and fasten. It ensures adequate contact area for a secure hold.
Enable both sides when purchasing equal lengths of hook and loop. Disable it if you only need one side or are pricing sides separately.
Typical waste ranges from 3% to 10% depending on cutting precision, defects, and small offcuts. Use higher values for complex layouts.
Common values are 0.25–1 in (6–25 mm). Increase for heavy duty stitching or where additional tail is required.
Check supplier rolls such as 5 yd, 10 yd, or metric equivalents. Enter the length in the same unit you selected above.
Yes. Measure the along path length of the curve or circumference and use that value as the closure path length.
Width does not change the length calculation but affects strength and price. Choose width based on application and manufacturer guidance.
Costs vary by brand width color and backing. Enter your actual price per unit to improve accuracy and include taxes or shipping separately.
