Join sewing pattern PDF tiles at an explicit scale
Join equal-size sewing pattern PDF tiles into one large vector sheet. Set columns, trim, overlap and scale; download a separate physical calibration square.

Read the guide ↗Before you start
Does it create a sewing pattern from measurements?
No. It joins an existing tiled pattern that you provide. It does not draft or fit garments.
Can I select one size layer?
Not here. Export or print the required visible size from a layer-aware PDF viewer before uploading. Layer state is not offered as an output guarantee.
Is the output life-size?
At 100% artwork scale the PDF dimensions are retained after trimming. The final printer or projector can still rescale it, so check a known measurement physically.
What order must the pages be in?
Left to right, top to bottom. Set the number of columns to match the original pattern grid.
Can I project the joined PDF?
Yes, open it in your projector viewer. Calibrate a known dimension at the cutting surface and recheck after moving the projector.
