The canvas is a view onto a poster that is usually far bigger than your screen. Zooming changes what you can see; it changes nothing about the poster or the export.
Zoom runs from 100%, which fits the whole poster on screen, up to 400%. You cannot zoom out past the fit — there would be nothing to see.
Browser and desktop
- Zoom slider — drag for continuous zoom, with the current percentage beside it.
- Zoom in and out buttons — on narrow windows the slider collapses to a − 100% + stepper.
Keyboard equivalents:
| Shortcut | Action |
|---|---|
| Cmd/Ctrl + = or + | Zoom in |
| Cmd/Ctrl + - | Zoom out |
| Cmd/Ctrl + 0 | Reset zoom to fit |
Hold Space and drag to pan, once you are zoomed in. At the 100% fit there is nothing to pan to, so it does nothing.
Android and iOS
Pinch to zoom. Once you are zoomed in, drag on empty canvas to pan. At the fit level dragging moves between pages instead, which is why panning only starts once you have zoomed.
There is no zoom slider on mobile, deliberately. Pinch is the native gesture on a touchscreen and it covers the need; a slider would take canvas space to duplicate something your fingers already do.
Zoom is not scale
Two things people conflate on their first poster:
- Zoom is how large the poster appears on your screen. It has no effect on the export.
- The poster size is how large it prints, set by grid mode or size mode.
Zooming to 300% does not make the print bigger or sharper, and zooming back to the fit does not make it smaller. If the printed poster came out the wrong size, zoom is not the cause — see the poster printed at the wrong size.
