LinkedIn Bildgrößen-Guide + kostenloser Resizer (2026)

LinkedIn personal profile sizes

**Profile photo** — **400×400 px** minimum (square, displays as circle). LinkedIn supports up to 8 MB and 7,680×4,320 px but displays at small sizes; 400×400 is the sweet spot.

**Background (banner) photo** — **1584×396 px** at a **4:1 aspect ratio**. Spans the top of your profile. Bottom 1/3 gets covered by your profile photo and name — design important elements in the top 2/3.

**Profile video** (Premium) — 30-second vertical video, 1080×1920.

LinkedIn post image sizes

**Single image post** — **1200×627 px** (1.91:1 ratio) is the universal recommendation. Works on desktop and mobile without cropping.

**Vertical image post** (mobile-optimized) — 1080×1350 (4:5). Takes up more feed space on mobile, drives 30-40% higher engagement than horizontal.

**Multi-image post** (carousel) — same dimensions per slide; max 10 slides. All slides should share the same aspect ratio.

**Document (PDF) post** — uploads as document, displays first page as preview. PDF pages render at native PDF aspect ratio.

LinkedIn article + newsletter cover sizes

**Article cover image** — **1200×627 px** (1.91:1). Shows at the top of the article and as the preview when shared on LinkedIn.

**Newsletter cover image** — **300×300 px** for the subscription icon, **1200×627 px** for the article hero.

**Article inline images** — recommend 1200 px wide, any height. LinkedIn resizes for mobile but quality is best at this width.

Articles + newsletters perform 5-10× better with custom cover images. Don't skip the cover.

LinkedIn company page sizes

**Company logo** — **300×300 px** (1:1 square). Appears in the sidebar of every company page and in feed posts from the company.

**Company cover image** — **1128×191 px** (~5.9:1) on desktop. Mobile crops to 640×340. Design assuming a vertical 191-px display strip on desktop and a much shorter band on mobile.

**Life tab hero** (recruiting page) — 1128×376.

**Showcase page cover** — 1128×191, same as company cover.

LinkedIn ad image sizes (Campaign Manager)

**Single image ad** — 1200×627 px (1.91:1) standard, or 1200×1200 (1:1) for mobile-optimized.

**Carousel ad** — 1080×1080 (1:1) per slide; 2-10 slides.

**Video ad** — 1920×1080 (16:9) or 1080×1920 (9:16 mobile). 3 seconds to 30 minutes.

**Conversation ad** — 250×250 px logo only; copy carries the message.

**Message ad (InMail)** — 250×250 px logo or banner 700×100.

Common LinkedIn image mistakes

Three patterns hurt LinkedIn posts most.

(1) **Horizontal images on mobile** — 1.91:1 horizontal posts render small on mobile (where 60%+ of LinkedIn traffic lives). Use 4:5 vertical or square for mobile-first content.

(2) **Text-heavy graphics under 1200 px wide** — LinkedIn's auto-compression turns small text into mush. Always upload at 1200 px wide minimum for any image with readable text.

(3) **Branded backgrounds with profile-photo collision** — for personal banners, the bottom 1/3 gets covered. Brand marks placed there disappear.
