Why image sizes matter on LinkedIn

LinkedIn renders images differently depending on placement — a profile banner, a feed post, and a company logo each have specific dimension requirements. Using the wrong size can result in cropping, blurring, or outright rejection.

For ads and sponsored content, incorrect aspect ratios can cause LinkedIn to refuse to serve the creative entirely. For organic posts, the algorithm may reduce reach when image quality is flagged as low.

Getting this right upfront saves hours of iterating and republishing. This checker validates your image against all 12 major placements at once.
