A practical toolkit for screen printers.

Screenprintcalc is a free collection of browser-based tools for planning screen-printing jobs. Estimate a selling price, plan materials, convert mesh units, and print a job sheet without creating an account.

A tool, with its workings shown

Every calculator includes its formula, editable example values, and the assumptions that can change its result. The estimates are only as reliable as the numbers you enter. Test jobs and supplier instructions should guide production decisions.

Independent and focused

Screenprintcalc is an independent software project by Kalindu De Silva. It does not offer printing, consulting, or booking services. There are no paid placements or affiliate links in this version.

Who is behind Screenprintcalc?

How the content is made

The tools and educational explanations are developed with AI assistance. Worked examples are constructed and arithmetic is checked against the stated formulas. The site does not present these examples as measured shop data. Read the editorial policy and calculation methods.

Start with the job

Use job pricing to check total cost and margin, then use the materials tools to refine your assumptions. Results are calculated locally and can be printed for your shop records.
