How to Prepare Images for Large-Format Printing (A1–A5)

Want your A1–A5 print to look crisp? Run this checklist before you export. For sizing, keep this print size calculator open while you work.

1) Start with the best source

  • Use the original file (not a screenshot or social export).
  • Prefer RAW → export to PNG or high-quality JPEG.

2) Target size & PPI

  • Aim for 300 PPI if viewed up close; 150–200 PPI works for posters viewed from a distance.
  • A-series at 300 PPI (approx pixels): A3 3508×4961, A2 4961×7016, A1 7016×9933. See the 300 DPI cheat-sheet.

3) Clean before upscaling

  • Reduce noise and fix exposure/white balance.
  • Heal obvious artifacts before enlarging—they only get bigger.

4) Upscale

  • Use 2–4× upscale to hit your target pixels. If you’re short, check limits with Max Print Size (by MP), then upscale and export the exact pixel size.

5) Sharpen last (lightly)

  • Apply subtle output sharpening after you reach final size.

6) Color & profile

  • Use sRGB unless your print shop asks for CMYK.
  • Avoid oversaturation—prints are less luminous than screens.

7) Export

  • PNG for graphics/flat color; JPEG (quality 90–100) for photos.
  • No watermarks or multiple compression passes.
