How to use this tool
- Browse by platform. Choose a platform pill to filter the placement table.
- Select a local image. Choose an image file or drop one on the page. Your browser reads it locally; it is not uploaded.
- Review shape and resolution. Compare aspect-ratio fit and pixel dimensions, then copy or export the displayed size recommendations.
Compare the image shape and pixel dimensions
Social platforms crop and display images differently for profile photos, feeds, banners, stories, and link previews. The recommended pixel width and height are only part of the fit: an image can have plenty of pixels and still lose content if its shape does not match the placement. Use the filter and sortable columns to find a target before you export a creative.
Choose Check image beside one placement to compare a local file against that target. The checker measures the image's aspect ratio separately from its resolution. A matching ratio with enough pixels is marked Ready; a small ratio difference is Close; a larger crop difference or dimensions below the recommendation is marked Needs adjustment. These labels describe shape and pixel fit, not guaranteed approval by a social platform.
To compare a design across several placements, filter to a platform and choose Check visible placements. The result lists each placement's shape and resolution assessment together, so you can see which crops need separate exports. A wide image used in a portrait frame will usually lose content on its left and right edges when filled; a narrow image in a wide frame may lose content at the top and bottom. Keep logos, faces, and text away from those edges when a crop is likely.
Sample placement dimensions
These sample targets come from the same data used by the interactive table, so the sizes shown here stay aligned with its filters and exports. Recommendations reflect common creator and publishing guidance reviewed in September 2026. They are not a promise that every account, device, or placement will render identically; platform interfaces and upload rules change.

Use file size as a reference
The checker displays the selected image's file size alongside its dimensions, but does not label it as passing or failing a platform limit. Image limits can depend on format and placement, and reported figures are not consistent across guides. For example, published Instagram size recommendations differ, so check the platform's current help information rather than treating one general number as a guarantee. The file-size display is useful when you are comparing export versions or preparing a smaller image for a slow connection.
Image processing stays in your browser. The guide reads dimensions from the selected or dropped image, reports its name and byte size, and does not upload or store the file. Use Copy size for a single pixel target or export the filtered and sorted table as CSV or JSON when you need placement specs in a design brief. Before publishing important work, verify the final crop, safe area, and accepted formats in the platform's own publishing interface.
Frequently asked questions
What are the ideal Instagram post sizes?
Common 2026 targets include square (1080×1080), portrait (1080×1350), landscape (1080×566), and a taller 3:4 grid image. Check Instagram's current crop behavior before publishing.
What size should a YouTube thumbnail be?
A commonly cited YouTube thumbnail target is 1280×720 pixels (16:9). The checker compares image shape and resolution; verify current file rules in YouTube Help.
Does my image leave my browser?
No. Your browser reads the image dimensions and file size locally. The file is not uploaded or stored by this tool.
Does the checker validate platform file-size limits?
It displays the selected file size for reference but does not apply a pass or fail limit. Platform limits vary by format and placement, and published figures can conflict, so check the platform’s current help page.
How often do social media image sizes change?
Platforms adjust display and upload rules periodically. These recommendations were reviewed in September 2026; verify with the platform's current help documentation before publishing important content.
