Affinity Designer to tiled A4 and US Letter

What print-at-home tiles need

• ✓Pages laid out separately for A4 and for US Letter, since neither fits the other
• ✓An overlap between pages, with alignment marks on the shared edges
• ✓A tile ID on every page and an assembly map on page 1
• ✓The test square on page 1, and print scaling switched off
• ✓Every size on its own layer, so sewists print only theirs

By hand, it's an artboard per tile for each paper size, with pieces moved into place on each, and a check that layers survive the PDF export.

The Sewpress way, from Affinity Designer

1. 1
   Set up your layers

   Make one top-level layer per size (S, M, L) and shared layers starting with an underscore (_grainlines, _notches, _test) in the Layers panel.

2. 2
   Export for Sewpress

   Export SVG: each top-level layer becomes a named group, which Sewpress reads as a layer. Upload it, and check the layer list and test square on the inspection screen.

3. 3
   Upload and check

   SVG export settings vary between versions. If the inspection screen says your test square reads 75 mm, the file was written at 72 units per inch: choose 72 there and it's fixed.

4. 4
   Build print-at-home tiles

   Sewpress places your master once and builds tiled A4 and US Letter, measuring the test square in each.
