About
About Propackinsights
Propackinsights is an independent educational site about packaging and the measurements behind it. We write for brand owners, designers, buyers, and students who need a clear answer before they order, design, or ship.
Each guide answers one specific question. We cover packaging materials, box and card sizes, conversions, design trends, and sustainability, and we explain the numbers in plain language so you can apply them right away.

Why You Can Trust Propackinsights
We build every guide around four standards.
Experience
We check sizes and quantities against real products and specifications wherever possible. Jenny Tessa reviews every guide against real packaging samples before publishing — measuring actual boxes, cards, and containers rather than relying on spec sheets alone. When a guide says a mailer is 9 × 6 inches, that number has been checked against a physical product.
Expertise
Jenny Tessa’s background spans packaging and print specifications, with hands-on experience sourcing materials and verifying product dimensions across the packaging supply chain.
Authoritativeness
We cite official sources such as standards bodies, government agencies, and manufacturer specifications.
Transparency
Each guide shows an update date, and we fix errors quickly when readers report them. Paid placements are marked as sponsored.
