Best used for
A balanced vertical canvas for content cards and carousel pages.
This is a creator-canvas and layout-safe-area guide, not a claim about mandatory upload rules. Check the destination platform’s current requirements before publishing.
It helps you choose a content canvas and layout boundary before making an image. 3:4 suits knowledge cards and carousel pages, 4:5 suits concise feeds, and landscape works for share images. It does not replace destination-platform upload requirements or crop a finished asset for you.
When one image must carry a conclusion, conditions, proof, and examples, do not turn it into a slogan just to fit a ratio. Start with a one-image summary, then move to a connected carousel if it is still too dense.
Use a free tool to solve the publishing detail first; when you are ready to turn an article, idea, or note into a publishable image, start in the studio.
