Social Media Image Size Checklist

Use image, design, content, and social tools to prepare captions, dimensions, hashtags, and preview assets before posting.

Start with the platform format

Square posts, vertical videos, banners, thumbnails, and story images use different dimensions. Match the asset to the placement before writing final copy.

Keep text readable

If an image includes text, check contrast, font size, safe margins, and cropping. A design that looks good on desktop may be hard to read on a phone.

Prepare the post as a package

Caption, hashtags, image size, link, and call to action should be checked together so the post is ready to publish without last-minute edits.

These tools are designed for estimates, formatting, planning, and workflow support. Check important results before using them in business, legal, financial, medical, or technical decisions.
