About MakerCalcs
MakerCalcs is for makers, crafters, print shops, and small-batch sellers who need practical numbers before they print, cut, price, or package a product.
Who builds MakerCalcs
Ethan Yang builds, tests, and maintains the MakerCalcs tools and their supporting guides. Each calculator is designed to make its assumptions visible so you can check the result against your own production setup.
What the tools help with
The calculators turn common production questions into visible, editable assumptions: how many items fit on a sheet, what margins are being used, what a batch may cost, and where a break-even price starts.
The goal is to help you compare options before wasting material or time, especially when a small setup choice changes the number of sheets, supplies, or units you need.
Why the results are useful
Calculations are built from clear inputs instead of hidden presets. When a tool depends on paper size, safe margins, bleed, gap, cost, or quantity, those values are shown so you can adjust them to match your own workflow.
Core calculator work runs in your browser, and tool pages explain the main assumptions and limits that can affect the answer.
What MakerCalcs is not
MakerCalcs is a planning aid, not the final authority for production or business decisions. Always test with your actual printer, cutter, software, material, marketplace fees, and shipping setup before relying on a result.
Feedback
If a calculator result looks wrong or a workflow is missing, send the details through the contact page. Good feedback includes the calculator URL, sizes, margins, material assumptions, and the result you expected.
