Leave room for the interface
The dashed area uses Feedloom’s conservative layout margins, scaled to this canvas. It is a visual guide, not an official platform guarantee or automatic text detection. Captions, buttons and devices can cover different areas.
Publishing APIs, ads and the native apps can have different limits. These presets suit the named placements; they are not a list of every size a native app accepts. Always preview in the app before posting.
How it works
- Pick the placement for your post, story or cover.
- Choose a local image. We check its dimensions in your browser.
- Check the crop and keep key text inside the guide before posting.
Your questions, answered
Do you upload my image?
No. The checker reads local bytes in your browser. It does not send your image to Feedloom or a third party.
Are these official safe zones?
The guide uses our renderer’s working margins. Platform controls vary, so check the final preview in the app too.
Does it detect hidden text automatically?
No. It reports dimensions and shows a crop with a visual overlay. You decide whether important details remain visible.
Can Feedloom check my designed posts?
Feedloom checks text fit and layout when it renders your posts. Create an account to plan and design a month from your website.
