How to Choose a Pouch Size Before You Design Artwork
A pouch that looks good empty can fail when filled. This article explains how fill weight, density, gusset depth, zipper placement, and seal area affect package size.
The problem, framed.
Pouch size decisions made after artwork is designed get expensive. Size drives material cost, shelf footprint, perceived value, and whether the customer thinks the package is honest — and it all starts with fill weight and density, not aesthetics.
What's actually going on.
Two products with identical weights need different pouches: 12 oz of chips occupies several times the volume of 12 oz of sauce. Bulk density converts weight to volume; fill efficiency (typically 50-60% of theoretical pouch volume for a stand-up) converts volume to dimensions. Headspace, seal areas, and gusset depth consume the rest.
