About PrintReference Lab

Reference-grade tools for print and packaging professionals.

What This Is

PrintReferenceLab.com is a collection of precision calculators for the print and packaging industry. Every tool is designed to be transparent, deterministic, and fast. No accounts, no tracking, no hidden assumptions.

Design Philosophy

Every calculation runs client-side with full formula transparency. Results are deterministic: the same inputs always produce the same outputs. We use standard IEEE 754 rounding, ISO paper dimensions, and clearly documented unit conventions. No server calls, no proprietary adjustments, no guesswork.

Who This Is For

  • Print buyers estimating shipping costs before requesting carrier quotes.
  • Production managers comparing paper stocks and calculating material requirements.
  • Designers verifying that their specified paper weight meets postal requirements.
  • Procurement teams cross-checking supplier-quoted weights against independent calculations.

PrintReferenceLab.com is an independent reference tool. Results are theoretical estimates based on standard paper dimensions and user-supplied grammage values. Always confirm final weights with a calibrated scale for regulatory, contractual, or postal compliance purposes.
