What is the best aspect ratio for LinkedIn PDF Carousels?

We strongly recommend 4:5 vertical portrait dimensions (1080x1350px) because it occupies maximum real estate on mobile device feeds.

What formats does LinkedIn support for Document slide posts?

LinkedIn supports PDF, PPT, PPTX, DOC, and DOCX formats up to 100MB and 300 pages max.

What exact PDF page size/crop settings should I use for LinkedIn document carousel slides so they don’t get center-cropped, and how do I validate it programmatically?

For LinkedIn document-style carousel pages, target a content frame with a strict 1:1 (square) or 4:5 (vertical) aspect, then ensure the PDF page CropBox matches that same aspect with no extra whitespace. Programmatically validate by rasterizing each page to 1080px (square) or 1080x1350px (4:5) and confirming the detected non-background bounding box stays within the frame margins—use a threshold of ≥96% coverage of width and height with ≤1px differences in the computed aspect ratio. If any page falls below 96% coverage or deviates by more than ±0.01 in aspect ratio, re-export with normalized crop boxes.

How can I prevent LinkedIn from truncating small text in a carousel PDF—what minimum font-size and safe-area rules should my aspect-ratio checker enforce?

LinkedIn tends to downscale PDF-rendered slide content differently depending on the chosen aspect, so enforce a safe-area and minimum legibility threshold. For 1:1, require key text to remain inside at least a 7% inset on all sides (a 1080px canvas implies ~75px padding), and for 4:5 enforce at least an 8% inset (1080x1350 implies ~108px padding) because vertical feeds compress more aggressively. Additionally, flag slides where the smallest estimated font height would rasterize below 28px at 1080px reference width—your checker should compute expected text height from bounding boxes and warn when it drops under 28px.
