LinkedIn aspect ratio in 2026: 1:1 native, supports 1:1, 16:9, 4:5, 9:16. Pixel sizes per ratio plus cross-platform conversion guide.
LinkedIn aspect ratio: 1:1 native (also supports 1:1, 16:9, 4:5, 9:16).
LinkedIn supports 4 aspect ratios in 2026: 1:1, 16:9, 4:5, 9:16. The native ratio — the one the feed and player are built around — is 1:1.
Why this matters for reach: LinkedIn's ranking signals include "watch through rate" and "visible engagement". A clip framed in the wrong ratio either letterboxes (black bars) or center-crops (key subject out of frame). Both signal low quality to the algorithm. Native-ratio uploads consistently out-perform reformatted ones on the same content.
Supported pixel dimensions per ratio: 1:1 (1080×1080), 16:9 (1920×1080), 4:5 (1080×1350), 9:16 (1080×1920). Render at the long-edge size for the ratio you target — going larger gets transcoded down, going smaller gets upscaled and softens text + faces.
Conversion gotchas when cross-posting to LinkedIn: - From wider sources (16:9 → 1:1): use a smart-crop (subject tracking) rather than naive center-crop. Center-crop loses faces if speakers move around. - From taller sources (9:16 → 1:1): pad with brand-colored bars, or use a blurred-fill background. Black bars suppress reach more than blurred fills. - From square (1:1 → 1:1): if staying square, extend the canvas with generative fill or a flat color rather than zooming in and cropping.
Note: 10min/5GB native upload widely cited.
