Canva to Print-Ready Files: A Seller's Workflow
The exact Canva canvas sizes, export settings, and post-export fixes (DPI metadata, ratio crops) that turn Canva designs into sellable printables.
Canva is where most printable sellers start — and where most print-quality problems start too, because Canva thinks in screens, not inches. This workflow gets true print-ready files out of it.
Step 1: set the canvas in pixels, not inches
Create a Custom Size canvas in px, at the largest print you intend to sell:
| You sell up to | Canvas (2:3 example) | Effective DPI at max size |
|---|---|---|
| 12x18 | 3600 x 5400 | 300 |
| 16x24 | 4800 x 7200 | 300 |
| 24x36 | 4800 x 7200 | 200 (good for posters) |
Note the ceiling: Canva maxes out around 8000 px per side, so a 300-DPI 24x36 (7200x10800 px) is not achievable in-app. 200 DPI at 24x36 is genuinely fine for wall viewing — just say so in the listing instead of claiming 300 (DPI bands explained here).
Design with a safe zone: keep text and focal elements inside the central 80% so the later ratio crops don't amputate anything (why, with the crop-loss table).
Step 2: export clean
- PNG at highest quality for graphics with flat color and text; JPG for painterly/photographic work.
- Turn OFF any "size x2" toggles pointed at a small canvas — upscaling in export is still upscaling.
- Skip "PDF Print" for wall art (buyers want images they can print at any size; PDFs lock the page size).
Step 3: fix what Canva didn't do
Canva's PNG/JPG carries 96 DPI metadata regardless of your pixel count. The pixels are right; the tag is wrong — and print dialogs, pharmacies, and print-on-demand upload checkers read the tag. You also still have only one shape, and buyers need five.
Both fixes are one step: drop the export into the Ratio-Pack Generator. It crops the five standard ratios at full resolution (draggable focal point per crop), writes 300 DPI into the actual file bytes, and reports the honest largest print size for each file.
Worked example: a quote print, start to listing
- Canvas: 4800x7200 px. Quote text centered, nothing within the top/bottom 700 px.
- Export PNG (flat colors + type = PNG territory), 9MB.
- Generator pass → five masters: 2:3 (untouched), 3:4, 4:5, 11x14, ISO A — the 4:5 crop needed a small downward nudge to keep the attribution line.
- Check readouts: 4:5 file prints 8x10 at 480 DPI, 16x20 at 240 DPI. Listing copy writes itself.
- Package per the 5-file strategy and upload.
Total time: about six minutes, most of it in Canva. The same flow works from Procreate with different step-1 settings — that version is here.
