How to make a poster

- 3Add your photo from Uploads and shapes or stickers from Elements.
- 4Set a solid color or gradient in the Background panel.
- 5Download as PNG for social media, or as PDF at 2× or 3× size for printing.
Build a clear hierarchy
A poster is read in three steps: the headline catches the eye from a distance, the key details (what, when, where) answer the next question, and the small print comes last. Make each level clearly bigger or bolder than the one below it.
Your headline should be readable from a few meters away, which usually means it fills at least a third of the poster's width. If everything is the same size, nothing stands out.
Use white space and alignment
Leave generous margins and empty space around the headline; crowded posters are skipped. Align text blocks to a common left edge or center line rather than scattering them across the page.
Limit yourself to two fonts: a bold display font for the headline and a clean font for the details. The editor's snap guides help you line elements up with the page center and each other.
Printing your poster
For print, download as PDF at 2× or 3× size so text and edges stay sharp. The A4 template exported at 3× is close to 300 dpi, which is the standard for print shops.
Keep text at least 5 mm from the edge, because many printers cannot print right to the border. If a print shop asks for bleed, extend the background past the trim line by the amount they specify, often 3 mm.
