Picks per inch (PPI) is a standard metric for fabric density, counting the number of horizontal weft yarns (picks) in one inch of woven cloth. A higher PPI indicates a tighter, finer, and generally more durable weave. Weavers and textile engineers use this measurement alongside ends per inch (EPI) to calculate fabric weight, shrinkage, and structural integrity.
