# How to Calculate Binding Consumption for Tops

Binding used in a top can be a knitted tape or woven tape. It depends on product design and styling. Normally, on knitted tops self-fabric is used for binding. Binding tape is used to finish the neckline, armhole (tank top), sleeve plackets, and front opening.

Binding tapes are cut in roll form. The binding is attached in a garment using binder (guide).   Read this article to know how you can calculate binding fabric consumption by yourself.

Step-1: Take your garment sample. Measure the seam length where you need to attach a binding. Measure the length in metric system (in centimeter or in meter). Add wastage allowance at the two ends of the binding.

If you like to know consumption in linear length then you will get it in step one. For woven fabric, binding tape consumption is measured in linear length. First, you measure length by tape width then convert this length by fabric width.

For knitted fabric purchase is done by weight (Kg).

In case you want to calculate binding fabric consumption in weight, then you need to find the area of the binding tape in square meters and multiply by GSM of the binding fabric.  Follow the set-2 and step-3.

Step-2: Measure the width of the binding including folding of the tape. If you don't know how much seam allowance added in the sample garment, open the binding from the garment, and measure the width of the tape.

Step-3: Calculate GSM of the Fabric. You will get the GSM detail in your fabric bill. If that is not available you can find the tape fabric GSM using this method.

Binding consumption in grams= (Length of the tape  x Tape width) x Tape fabric GSM

Example: Assume that you need to calculate binding consumption for a t-shirt. Assuming that binding is used only on the neckline.
• Neckline length: 50 cm (circumference)
• Width of the binding tape (open width): 4 cm
• Fabric GSM = 180
Binding consumption: (0.50 x 0.04) x 180 = 3.6 grams (0.0036 Kg)

Note: In the calculation, measurements are taken in meters.
