How we calculate this

Methodology and source handling

We convert physical sizes to inches, multiply by the selected DPI/PPI value, and round to whole pixels.

Quick answer

Copy-ready answer

LinkedIn Document ads are not one fixed pixel canvas. Use a consistent standard page layout such as Letter or A4, keep the document under 100 MB, and prefer under 10 pages unless the campaign needs a longer document.

Formula

How to calculate this size

Pixel formulapixels = millimeters / 25.4 x PPI

210 mm x 300 PPI = 2,480 px wide.

Trim result2,480 x 3,507 px

Use this when the artwork stops at the finished edge.

Bleed result2,480 x 3,507 px

Add 0 mm per side before calculating pixels when artwork reaches the edge.

Common mistakes

Avoid these linkedin document ad size and specs problems

Missing the exact placement size

Ad platforms can use different specs for feed, story, banner, and display placements.

Compressing after upload only

Export a clean, compressed file before upload so text and logos stay sharp.

Skipping safe-area checks

Keep logos and copy away from crop-prone edges and UI overlays.

LinkedIn Document Ad specs are file and layout based rather than a single pixel canvas. PixelMeasures uses A4 as the embedded calculator example because LinkedIn lists A4 as a supported standard PDF layout.
