The Ultimate Guide to LinkedIn Image Sizes: Dimensions, Ratios, and Best Practices

First impressions online are brutally fast. On a professional network like LinkedIn, your visual branding often speaks seconds before your actual words do. Whether a hiring manager is scanning your profile, a potential client is evaluating your company page, or a peer is scrolling past your latest thought-leadership post, high-quality, properly cropped images set the tone for your credibility.

Unfortunately, LinkedIn’s layout is notorious for awkward auto-cropping if you upload images in the wrong dimensions. A blurry banner, a cut-off profile photo, or a pixelated infographic can instantly undermine an otherwise brilliant post.

This comprehensive guide breaks down every essential LinkedIn image size, aspect ratio, and technical constraint so you can optimize your professional presence with precision.

1. Personal Profile Images

Your personal profile is your digital handshake. Getting the primary visual assets right ensures you look sharp, polished, and detail-oriented.

Profile Picture

• Dimensions: Minimum $400 times 400$ pixels (supports up to $7680 times 4320$ pixels).
• Aspect Ratio: $1:1$ square (displayed as a circle).
• Max File Size: 8 MB.
• Formats: JPEG, PNG.
• Pro Tip: LinkedIn crops your square photo into a circle, meaning the extreme corners will be hidden. Center your face and leave a small padding around your shoulders so nothing crucial gets sliced off.

Personal Background / Banner Photo

• Dimensions: $1584 times 396$ pixels.
• Aspect Ratio: $4:1$.
• Max File Size: 8 MB.
• Formats: JPEG, PNG.
• Pro Tip: Your profile picture overlays the bottom-left corner of your banner on desktop views. Keep key visual elements, text, or logos shifted toward the middle-right to prevent them from being blocked.

2. Company Page Images

If you manage a brand or business page, your visual assets need to reflect corporate polish.

Company Logo

• Dimensions: $400 times 400$ pixels recommended (minimum $268 times 268$ pixels).
• Aspect Ratio: $1:1$ square.
• Max File Size: 3 MB.
• Formats: JPEG, PNG.

Company Page Cover Image

• Dimensions: $1512 times 256$ pixels.
• Aspect Ratio: Roughly $5.91:1$.
• Max File Size: 3 MB.
• Formats: JPEG, PNG.
• Pro Tip: Company banners are shallower than personal banners. Keep text minimal and design clean so it doesn’t look cluttered when scaling down to smaller monitor resolutions or mobile screens.

3. Feed Post Image Sizes

The LinkedIn feed is crowded, and the format of your post image dictates how much screen estate you control. Because a majority of traffic browses via mobile, vertical orientation yields powerful engagement results.

| Format | Dimensions | Aspect Ratio | Best Used For |
| :— | :— | :— | :— |
| Portrait | $1080 times 1350text{ px}$ | $4:5$ | Infographics, high-engagement content, mobile optimization |
| Square | $1080 times 1080text{ px}$ | $1:1$ | Versatile standard content, quote cards, carousel slides |
| Landscape | $1200 times 627text{ px}$ | $1.91:1$ | Link previews, external article sharing, broad announcements |

• Max File Size per Photo: 5 MB.
• Accepted Formats: JPEG, PNG, WebP, HEIC (from iOS).
• Carousel / Document Posts: Design your slides as $1080 times 1080$ square PDFs. They render cleanly across all devices without unexpected boundary cutoffs.

Quick Checklist for Flawless Uploads

1. Check Your Ratios First: Pixel dimensions matter, but matching the native aspect ratio ($4:1$ for personal banners, $4:5$ for portrait posts) prevents LinkedIn’s automated cropping algorithms from ruining your framing.
2. Mind the Safe Zones: Keep text and focal points away from borders and corners—especially the bottom-left area of personal profiles where the avatar intersects the banner.
3. Use the Right File Type: Choose PNG for graphics containing sharp text, logos, or geometric layouts. Choose JPEG or WebP for real-life photographs to keep file sizes lean without sacrificing crisp clarity.
