Frequently Asked Questions | FAQs

What is pick spacing in weaving?

In weaving, pick spacing refers to the distance between successive weft yarns or picks in a woven fabric. It determines the density and appearance of the fabric. The pick spacing can vary depending on the desired outcome, the type of loom being used, and the weave structure.

Pick spacing is usually measured in picks per inch (PPI) or picks per centimeter (PPC). A higher pick spacing means fewer weft yarns per unit length, resulting in a more open and airy fabric with visible gaps between the yarns. This can create a lightweight and breathable fabric.

Conversely, a lower pick spacing indicates a higher density of weft yarns, resulting in a tighter and denser fabric with less visible gaps. Fabrics with a lower pick spacing tend to be thicker, more durable, and less breathable.

The pick spacing is determined by the weaving pattern and the number of picks inserted per inch or centimeter. It can be controlled by the weaver by adjusting the speed of the loom, the tension of the weft yarn, or by using different reeds or combs in the loom that control the spacing between the warp yarns.

Overall, pick spacing plays a significant role in the appearance, drape, and texture of woven fabrics, and it is an important parameter that weavers consider to achieve the desired characteristics in their woven creations.
