How to Make Canva Files Print-Ready (Poster Sellers, Read This)
Getting files ready for print-on-demand is simpler than it looks. If you design in Canva, follow this setup and your posters will print sharp and professional — whether you’re using PrintShrimp or any reputable print partner.
TL;DR: Fast Checklist
-
Design at the final print size (correct aspect ratio)
-
Target 300 DPI at the final size (see pixel table below)
-
No bleed or crop marks needed for posters
-
Keep key elements away from edges
-
Export JPEG (High quality) in sRGB
-
Keep files < 75 MB (2–25 MB typical)
-
If your art came from AI, upscale before export
-
Zoom to 100% — if it’s crisp on-screen, it’ll print crisp
1) Set Up Your Canva Canvas for 300 DPI
Printers care about effective DPI at the final print size (pixels per inch once printed). Your goal: 300 DPI.
Common poster sizes → pixel targets (~300 DPI):
| Size | Pixels (W×H) |
| 8×10" (4:5) | 2400 × 3000 |
| 11×14" (4:5) | 3300 × 4200 |
| 12×16" (3:4) | 3600 × 4800 |
| 16×20" (4:5) | 4800 × 6000 |
| 18×24" (3:4) | 5400 × 7200 |
| 24×36" (2:3) | 7200 × 10800 |
| A4 | 2481 × 3507 |
| A3 | 3507 × 4960 |
| A2 | 4960 × 7016 |
| A1 | 7016 × 9933 |
Canva → Create a design → Custom size → enter the pixel dimensions above.
Note: Aspect ratio matters. Don’t stretch between ratios — A-series ≠ 4:5 ≠ 2:3. Make separate files per ratio you sell.
2) Bleed, Margins & Edges
-
No bleed or crop marks required for posters with PrintShrimp (we print border-to-border).
-
Leave a few mm of breathing room — avoid tiny text or critical details right at the edge.
3) Colour Settings
-
Canva exports in RGB; sRGB (default) is perfect for reliable screen-to-print conversion.
-
Expect minor differences vs backlit screens (especially deep blacks/greys).
4) Export Settings (Every Time)
In Canva:
-
Share → Download
-
File type: JPEG
-
Quality: High (100)
-
Size: 100% (because you already set correct pixels)
-
Colour profile: sRGB (default)
Why JPEG? Small, sharp, and universal. PNG offers no print advantage for posters and often results in massive file sizes that slow down fulfillment.
5) Using AI Artwork? Upscale First
Midjourney or Stable Diffusion outputs may be too small for large posters. Upscale to hit 300 DPI at your target size, then place that upscaled image into Canva.
Reliable upscalers: Adobe Super Resolution, Topaz, or Magnific (2×–4×).
6) DPI FAQ (Read This)
“My file info says 72/96 DPI — what now?”
Ignore that metadata tag. What matters is the effective DPI at your final print size: DPI = pixels ÷ inches.
Example: 5400×7200 px printed at 18×24" = 300 DPI (Perfect).
Final Word
For dependable print quality, aim for 300 DPI at the final size. Get your pixels right, stick with sRGB, skip bleed, and export a high-quality JPEG. Do that, and your Canva posters will print beautifully — every time.
