Profile photo & background banner

Profile photo: 400×400 px (1:1). Use PNG/JPG. Keep important subject centered; leave 20–40 px internal margin for safety.

Background banner (cover): 1584×396 px recommended — shows differently across devices. Keep key text/logo inside the center area; test on desktop and mobile.

Company Page assets

• Logo (square): 300×300 (some references suggest 400×400 for higher-res). Use PNG for logos with transparency.
• Cover image (company page): common recommended size 1128×191 px (varies by template). Test how it crops on the page layout.
• Life tab / hero images: follow LinkedIn Page documentation for module-specific sizes (often 1128×376 or 1128×191).

Post images (feed)

LinkedIn supports a range of aspect ratios. Best practice:

• Square: 1080×1080 px — safest cross-platform.
• Landscape (recommended for link previews & sponsored posts): 1200×627 px (≈1.91:1).
• Portrait: up to 1080×1350 px (4:5) — grabs more screen on mobile.

Keep critical content centered; LinkedIn may crop thumbnails in some views. Minimum width commonly recommended: 1080 px.

Carousel posts & ads

Carousel cards are 1:1. Recommended resolution: 1080×1080 px. Cards will be scaled and thumbnails generated by LinkedIn; keep text/CTA away from edges.

Max cards usually: 10 for carousel ads. File types: JPG/PNG.

Video specs (feed & ads)

• Supported aspect ratios: 16:9, 1:1, 4:5, 9:16. Use the ratio that fits your creative goal.
• Resolution range: min 360×360 up to 1920×1080 depending on ratio; LinkedIn Ads docs list exact min/max per ratio.
• File type: MP4 (H.264) or MOV; thumbnail JPG/PNG (max 2MB for thumbnail).
• Frame rate: up to 30 fps commonly recommended; bitrate: follow ad platform recommendations (higher bitrate for 1080p videos).

LinkedIn Ads & thumbnails

• Single image sponsored content: recommended 1200×627 px (1.91:1) for strong desktop & mobile display.
• Carousel ads: 1080×1080 px per card (1:1).
• Maximum image file size: varies by placement (often 5–10 MB for ads), check LinkedIn Ads manager for current limits.

Photoshop & export tips

• Canvas: set to pixel dimensions; work at 72 ppi (or 2× for retina exports).
• Color profile: sRGB.
• Guides: add center safe-zone guides for covers and banners; keep top/bottom/side padding for text.
• Export: JPG for photos (quality 70–85%), PNG for graphics with text/transparency.
