About
PressMath — print math for real jobs
PressMath is a utility website for print shops, DTF operators, apparel decorators, vinyl shops and online sellers. Each tool answers one clear production or pricing question: size a print, check DPI, pack a gang sheet, estimate film cost, or see marketplace profit before you publish.
Who builds PressMath
What we believe
- Utility first. The calculator must work above the fold — not hide behind fluff.
- Explain the math. Every important tool includes formula notes, a worked example, reference tables and FAQs.
- Topical depth. We grow in clusters (image/print size, DTF cost, shop pricing) instead of spraying unrelated calculators.
- No thin pages. If a URL cannot help a shop finish a decision, it does not ship.
Who it is for
Owners and operators who quote jobs weekly, Etsy and POD sellers who need fee clarity, and designers who convert inches and DPI every day. If you need a custom calculator embedded on your shop site, contact us — PressMath is also our portfolio for that service.
How the site is built
Calculators run in your browser (fast, private inputs). Every important page keeps the formula, an example and related tools nearby — see the full list on the site map. Results are estimates — always verify against your equipment, supplier invoices and local fee rules.
