Sewing-pattern features
Everything you need to get a printed pattern that's exactly the size the designer intended.
Choose your size with PDF layers
Patterns with size layers show them as checkboxes. Turn off every size but yours so the cutting line is easy to follow.
Test square
Every print gets a 5 cm or 1 in test square plus a ruler on the first sheet, so you know it's right before printing the rest.
Print every page at once
Multi-page copy-shop files (one A0 per page) print into a single PDF, with sheets labelled P1-A1, P2-A1…
Skip blank sheets
Pattern pieces rarely fill the whole A0. Empty sheets are dropped automatically, saving paper and ink.
Trim lines & diagonals
Dashed trim lines and continuous diagonals make taping 30+ sheets together much less fiddly.
Mirror & crop
Flip a piece to cut a mirror image, or crop to just the piece you need to re-print.
Centimetres or inches
Work in cm, mm or inches. Overlap, grid and ruler follow your choice.
Copy-shop sizes too
Re-tile a pattern to A0, A1, Arch D (24×36″) or Arch E for a print shop or plotter.
Vintage grid patterns
Enlarge “1 square = 1 inch” diagrams from old books by calibrating across the grid.
How to print an A0 sewing pattern on A4 or Letter
Open the A0 file
Use the copy-shop / projector-free large-format PDF. If it has several pages, tick “Print every page”.
Pick your size
Under PDF layers click None, then tick your size and the layers for notes and grainlines.
Print at 100%
Use “Actual size” and measure the test square on sheet A1. If it's right, print the rest.
Tape together
Follow the assembly guide, trim on the dashed lines and match the diagonals across each join.
Why the test square matters
Printers love to “help” by shrinking pages to fit their margins. A 3% shrink sounds tiny, but on a 100 cm hip measurement it's 3 cm – a whole size.
- Always print at 100% / Actual size.
- Measure the test square with a ruler, not a tape measure.
- If your printer is still slightly off, calibrate against the pattern's own test square and print again.
Cosplay & foam templates
Armour and prop patterns for EVA foam and Worbla are often shared as big PDFs or images. Calibrate from a known measurement, mirror for left/right pieces and print them full size.
Sewing pattern FAQ
How do I print an A0 sewing pattern on A4 or Letter paper?
Open the A0 (copy-shop) PDF in TrueScale Print, choose A4 or Letter, turn off the size layers you don't need, then print at 100% / Actual size. Check the test square on the first sheet, trim on the dashed lines and tape the sheets together.
How do I print only my size?
If the pattern PDF has layers, they appear in the Source panel. Click None, then tick only your size (and any layers for notes or the cutting line). Not every pattern has layers – the designer has to include them.
My test square measures wrong. What do I do?
Make sure the print dialog is set to 100% or Actual size, not Fit or Shrink. If it is still off, click Calibrate in TrueScale Print, measure across the pattern's test square and type its stated size.
Can I enlarge a vintage pattern from a grid diagram?
Yes. Scan or photograph the diagram, open it, click Calibrate and measure across several grid squares, entering their real size, for example 10 squares = 10 in.
Is it OK to print a pattern I bought?
Printing a pattern you've bought for your own use is normally what the designer intends. Check the pattern's licence, and don't share the files or prints.
