Free label and barcode calculators
Six free calculators for thermal label work: GS1 check digits, dpi to dots, label size, barcode X-dimension, labels per roll and ribbon usage. Runs in your browser.
HOW IT WORKS
Three screens from data to printed label.
No copy-paste, no hunting for templates. The same flow repeats for every record.
Printer status, quick actions and recent work in one place.
Text, barcodes, QR and images placed on the real media size.
See the label, the printer state and the copy count before it prints.

Calculators by job
02
Barcode and GS1
Paste the digits without the check digit and get it, or paste the full number and find out whether it is right before you print a thousand of them.
Barcode X-dimension and quiet zone calculatorThe narrowest bar has to land on whole printer dots. This shows the width you asked for, the width you will get, and whether that still scans.
03
Printer and resolution
A thermal printer cannot place half a dot. This shows the exact dot count for a measurement, the value it will round to, and how far that moves the edge.
Label size calculatorGive it the label you are holding and it returns every number a printer setup screen asks for, including the pitch that drives media detection.
ZPL inspectorPaste a Zebra label format and get it back in plain English: how big the label is, what it prints, and the mistakes that stop it printing at all.
04
Media and consumables
How many labels are actually on that roll, worked out from its geometry rather than from the number printed on the box.
Thermal ribbon usage calculatorThermal transfer ribbon advances with the label whether the label is full of ink or nearly blank, so consumption follows label length, not coverage.
ANY PRINTER
Design it, bind your data, print on the printer you already own.
Zebra, TSC, Toshiba, Epson and more — over USB, network or Bluetooth, with no driver to install.

Do this on real labels
The calculators answer one number at a time. LabelInn applies the same maths across a whole design, a whole spreadsheet and a whole print run — and sends it to the printer without a driver. · Free · No signup · Runs in your browser
