How to use LinkedIn image size checker?

Pick where the image is going: a post, your banner, your profile photo or a company page cover. The tool shows the recommended dimensions, aspect ratio and max file size for that slot. Drop in your image or type its dimensions if you don't have the file handy, and you'll get a pass/fail against LinkedIn's own numbers. For post images, you'll also see how your shape compares to real engagement data from hundreds of thousands of posts.

Is this tool free?

Yes, completely free. No account needed, no limits on how many times you use it. Your image never leaves your browser, and we don't collect or store anything.

What size should a LinkedIn banner be?

For a personal profile, LinkedIn recommends 1,584 × 396px, under 8 MB, as a JPG or PNG. For a company page cover, the spec is different: 4,200 × 700px, max 3 MB. Several tools and guides online list 1,128 × 191px as a company page banner size. That figure doesn't appear anywhere in LinkedIn's own documentation. The actual 1,128px figure belongs to a different module (the Life tab main image, at 1,128 × 376px), not the page cover.

What size should a LinkedIn post image be?

LinkedIn's own guidance for a photo post is 1,080px wide, with an aspect ratio between 3:1 and 4:5. Anything outside that range gets centered and cropped. A lot of formatting guides recommend 1,200 × 627px landscape instead. That number is real, but it's LinkedIn's spec for the link-preview card on Company Page posts that include a URL, not for a photo post. LinkedIn's own help page says explicitly that spec doesn't apply to image-only posts. Worth knowing before you build a post around it.

What size should a LinkedIn profile photo or company page logo be?

LinkedIn doesn't publish an official dimension for personal profile photos, despite what a lot of guides claim with confidence. For a company page logo, there is a published spec: 400 × 400px recommended, 268 × 268px minimum. Where LinkedIn hasn't stated a number, this tool follows common industry guidance and tells you so instead of presenting a guess as fact.

Does image shape affect how many people see my post?

Yes, and the gap is bigger than most guides suggest. Across 368,489 single-image posts, portrait images earn a 2.83% median engagement rate, against 2.54% for square and 2.14% for landscape. That puts portrait 32% ahead of landscape. Portrait is also the most common shape already, at 44.5% of posts, so the crowd and the data agree here. If your image doesn't have to be a specific shape for the content, 1,080 × 1,350px portrait is the safer default.
