Plotter Calculator
How much roll do you need? Enter your pattern dimensions and plotter width — get the roll length, orientation, and a layout diagram.
Pattern dimensions (in)
Enter the total size of the full pattern layout. Width = across the roll. Height = along the roll (this becomes the roll length needed).
Plotter vs. print shop
A home or studio wide-format inkjet plotter (like the HP DesignJet, Canon imagePROGRAF, or Epson SureColor series) prints on roll paper — typically 24" or 36" wide. The roll feeds continuously, so the only limit is roll length. Patterns designed for A0 or large format output print perfectly on a 36" roll.
Most indie pattern brands now offer a "wide format" or "plotter" PDF alongside the tiled home printer version. This is a single large PDF page — just send it directly to the plotter at 100% with no scaling. Check the test square before committing to a full roll.
Setting up the print job
In your plotter software (HP Utility, Canon Print Studio, Epson Print Layout, or directly from Adobe Acrobat), set:
- Paper size: custom, matching the pattern dimensions (or larger)
- Roll width: your actual roll width (e.g. 36")
- Scale: 100% / Actual Size — never "Fit to Roll"
- Color profile: none / passthrough (patterns don't need color management)
Add 2–3" to the length when setting up the job to allow for the paper feed mechanism to catch and release cleanly. Most plotters waste 1–2" at the start of a roll.
Pattern PDF doesn't have a plotter version?
If you only have the tiled home-printer PDF, you can reassemble it into a single large page using free tools like PDF Arranger (Linux/Windows), the pdfposter command-line tool, or Adobe Acrobat Pro (merge pages into a single large canvas). Many sewing communities also share workarounds for specific brands.
