Do I need to buy hook and loop tape separately?

Hook-and-loop tape comes in two forms: on a roll with hook and loop side by side, or as separate hook and loop rolls. Buying separately lets you position each side independently. Both sides are needed for a closure.

What type of hook-and-loop tape should I use?

Sew-on tape is most versatile and durable. Adhesive-backed tape is quick but may not withstand washing. Iron-on tape bonds with heat. For garments, always use sew-on tape for durability.

What width hook-and-loop tape should I use?

16mm for lightweight closures and small items. 20mm is the most common for garment overlaps and cushion covers. 25mm and wider for bags, equipment covers, and heavy-duty applications.

How do I sew hook-and-loop tape?

Use a standard presser foot and medium stitch length. Sew around all four edges of each piece. Use a polyester thread — cotton thread can be cut by the hooks. Round the corners to prevent peeling.

How We Calculate This

Hook-and-loop tape needs equal lengths of hook and loop sides. Total tape is the closure length multiplied by the number of closures, times two for both sides.

The formula

Total per side = Closure length × Number of closures

Total tape = Hook length + Loop length (both sides)
