Checked quarterly." site: "Onmark" --- # Social media image sizes (2026) **About this guide:** - Marketing - 1 min read - Last updated 28 September 2026 - By Sam - Guide In short For most feeds, use 1080 × 1350 (a 4:5 ratio). It works on both LinkedIn and Instagram. Use 1080 × 1920 (9:16) for Stories and Reels, 1200 × 627 for link cards, and at least 1200 × 900 for Google Business Profile posts. Keep text away from the edges, because every platform crops. ![Outlines of the main social image formats: 4:5, 9:16, 3:4 and 1.91:1](https://cdn.sanity.io/images/0jqu7o0g/production/27d360405d76ab7562da979a5e8a49e9df09b465-3200x1800.png) Free toolCrop · ratio · contrast Social image check Drop an image into our free Social image check to see how it crops on every format below.

[Open the tool](https://www.onmark.com.au/tools/social-image-check) ## LinkedIn | Format | Size (px) | Ratio | Notes | | --- | --- | --- | --- | | Feed image | 1080 × 1350 | 4:5 | Takes up the most feed space. LinkedIn accepts ratios from 3:1 to 4:5. | | Square image | 1080 × 1080 | 1:1 | The safe choice when one image is used across several platforms. | | Document carousel | 1080 × 1350 | 4:5 | Upload as a PDF. Portrait works better on phones than A4 or landscape. | | Link card | 1200 × 627 | 1.91:1 | Set as the page's Open Graph image. | | Company page cover | 1128 × 191 | ~6:1 | Upload at double size (2256 × 382) so it stays sharp. The logo covers the bottom left, and mobile crops hard, so centre your message. | | Personal profile banner | 1584 × 396 | 4:1 | The profile photo covers the bottom left. | | Logo or profile photo | 400 × 400 | 1:1 | Shown as a circle on profiles. | ## Instagram | Format | Size (px) | Ratio | Notes | | --- | --- | --- | --- | | Feed post (designed) | 1080 × 1350 | 4:5 | The default for graphics, carousels and anything you might boost as an ad. | | Feed post (tall) | 1080 × 1440 | 3:4 | Fills the profile grid with no crop. Best for phone photos posted as they are. | | Profile grid | shows as 3:4 | 3:4 | Every post is cropped to 3:4 on your profile, so keep text and faces in the centre. | | Story or Reel | 1080 × 1920 | 9:16 | Keep text out of the top 14% (~270px) and the bottom 20% (~400px), where the app's buttons sit. | | Reel cover | 1080 × 1920 | 9:16 | Also cropped to 3:4 on the grid, so centre the title. | Tip Design at 4:5 and keep your headline, logo and faces inside the centre 3:4 area. That way the post works in the feed, on the grid, and as an ad. ## Google Business Profile | Format | Size (px) | Notes | | --- | --- | --- | | Cover photo | 1024 × 576 (16:9) | Google crops it differently in Search and Maps, so centre the subject. Don't go below 720px wide. | | Logo | 720 × 720 (1:1) | Use your symbol, not the full wordmark. It can be cropped to a circle. | | Update post image | 1200 × 900 (4:3) | Keep text to a minimum. 720 × 720 also works. | | All photos | at least 720 × 720 | JPG or PNG, 10 KB to 5 MB. The minimum accepted is 250 × 250. | Note Use real photos on your Google Business Profile, not stock: your team, your work, your premises. Google favours authentic imagery. ## Email newsletters | Format | Size (px) | Notes | | --- | --- | --- | | Content image | 1200 wide, any ratio | Displays at 600px, and the doubled width keeps it sharp on retina screens. | | Header | 1200 × 400 | Many email apps block images by default, so never put key information only in an image. | ## Before you post ## Checklist - The size matches the format above - Text sits inside the safe zones - Text on the image passes 4.5:1 contrast, or 3:1 for large text - The file is under 5 MB (Google) or 10 MB (LinkedIn) - Alt text is written: its purpose, plus any words in the image ### Why does my image look blurry? It's usually too small, or it has been compressed twice. Export at the exact size, as JPG at around 85% quality for photos or PNG for text. ### Is square still fine? Yes, but 4:5 takes up more of the screen on both LinkedIn and Instagram. ### How often do these change? Several times a year.
