LinkedIn specs
The exact dimensions, safe zones, and limits LinkedIn assets must hit. Design to the recommended size, keep critical content inside the safe area, and verify legibility at the in-feed scale a phone actually renders. Specs are LinkedIn's published guidance as of 2026 — confirm against the current Help Center before a major launch.
Profile & Company Page
The persistent brand assets. The cover image crops aggressively across breakpoints, so anything that must be seen — the logo, a tagline — belongs in the horizontal center band, never the corners.
| Asset | Dimensions | Notes |
|---|---|---|
| Company logo | 300 × 300 px | Square. Displays as small as 60 px — use the compact mark, not the full lockup. PNG, transparent. |
| Company cover / banner | 1128 × 191 px | ≈ 6:1. Keep type centered; edges are masked on mobile and behind the logo badge at lower-left. |
| Personal profile banner | 1584 × 396 px | 4:1. Lower-left ~25% is covered by the profile photo on desktop. |
| Profile photo | ≥ 400 × 400 px | Circular crop — keep the subject centered, no square-corner content. |
| Headline | 220 characters | Indexed in search; lead with role + value, not a slogan. |
Image posts
Four aspect ratios cover everything. Portrait (4:5) claims the most vertical space in the feed and is the default for single-image posts; the 1.91:1 link card is what renders when you share a URL.
| Format | Dimensions | Use |
|---|---|---|
| Portrait (4:5) | 1080 × 1350 px | Default single image — maximum feed real estate. |
| Square (1:1) | 1080 × 1080 px | Quote cards, stats, carousel frames. |
| Link share (1.91:1) | 1200 × 627 px | Auto-pulled OG image when sharing a URL. Set this on blog posts. |
| File type | PNG / JPG | PNG for type-heavy graphics; JPG for photos. Under 5 MB. |
Document (carousel) posts
LinkedIn's carousel is a PDF upload, not a multi-image post. High dwell time, strong for step-by-step explainers — a natural fit for "5 things to know about probate" content.
| Spec | Value | Notes |
|---|---|---|
| Aspect ratio | 1:1 or 4:5 | Square (1080 × 1080) is safest; portrait gains height. Keep it consistent across all pages. |
| Page count | Practical 6–12 | Platform allows up to 300; design for completion, not the cap. First slide is the hook, last is the CTA. |
| File | PDF, ≤ 100 MB | Export at 150–300 dpi equivalent so type stays crisp on retina. |
| Safe margins | ≥ 64 px inset | Page-turn affordances and counters overlay the edges — keep content inset. |
Video
Most video is watched muted in-feed — captions are mandatory, not optional. Square and portrait outperform landscape for organic reach.
| Spec | Value | Notes |
|---|---|---|
| Aspect ratios | 1:1, 4:5, 9:16 | Square or portrait for feed; 16:9 only for long-form / linked content. |
| Resolution | 1080 × 1080 min | Up to 4K supported; 1080 is the practical floor. |
| Length | 15s – 10 min | Sweet spot 30–90s for organic. Hook in the first 2 seconds. |
| Captions | Burned-in or .SRT | Required — see accessibility. Branded lower-thirds come from the templates page. |
| File | MP4, ≤ 5 GB | H.264, ≥ 30 fps. |
Copy & character limits
The feed truncates the post body fast. Everything that earns the click has to live above the fold — before the "…see more".
| Field | Limit | Guidance |
|---|---|---|
| Post body | 3,000 characters | Hard cap. Most posts perform best far under it. |
| Visible before "see more" | ~140 (mobile) / ~210 (desktop) | Front-load the hook. No critical info or CTA below the fold. |
| Hashtags | 3–5 | Specific over broad (#EstatePlanning > #Law). Place at the end, not mid-sentence. |
| Document title | ≤ 60 characters | Shown above the carousel — make it the value proposition. |
Do & don't
- Design to the recommended pixel size, then preview at phone scale before approving.
- Keep the logo and any must-read text inside the safe center band of cover images.
- Use portrait (4:5) for single images and consistent square frames across a carousel.
- Caption every video — assume sound is off.
- Set the 1200 × 627 OG image on every blog post so link shares render on-brand.
- Place logos or text in the corners of a cover image — they get cropped or masked.
- Bury the hook or CTA below the "…see more" fold.
- Mix aspect ratios within one carousel, or upload a carousel as separate images.
- Ship video without captions, or rely on tiny type that fails at thumbnail scale.
- Stuff 10+ broad hashtags — it reads as spam and dilutes reach.
