LinkedIn Carousel Size & Specs (2026): The Only Cheat Sheet You Need

Getting the size right is the difference between a crisp, professional carousel and one that shows up blurry or cropped in the feed. Here are the specs that matter in 2026, and the choices we recommend.

Recommended dimensions

For LinkedIn, two ratios work best:

• →Portrait 4:5 - 1080 × 1350 px. Takes up the most vertical space in the feed, which means more attention. This is the default we recommend.
• →Square 1:1 - 1080 × 1080 px. Safe and versatile; also perfect if you'll reuse the slides on Instagram or X.

File format and limits

• →Format: PDF for document posts. Reathy exports your whole carousel as a single PDF automatically.
• →Pages: LinkedIn supports up to 300 pages, but 6-12 slides is the sweet spot for engagement.
• →File size: keep it under ~100 MB (you'll rarely get close with text-based slides).
• →Resolution: export at 2× so text stays sharp on high-DPI screens.

Design settings that read well in the feed

• →Big type: your title should be readable as a thumbnail. If you have to squint, it's too small.
• →One idea per slide: crowded slides lose people mid-swipe.
• →High contrast: dark text on light, or light text on a dark or photo background with a scrim.
• →Consistent branding: same theme, same handle on every slide.

The fastest way to hit these specs

Instead of setting up artboards by hand, Reathy ships with 1080 × 1350 and 1080 × 1080 presets and exports at 2× automatically - so every carousel is the right size and sharp by default. Pick a format, and you're done.
