Social media image safe areas: what gets cropped on LinkedIn, X and YouTube

Direct answer

Every social platform crops uploaded images to its own aspect ratio before showing them in a feed. A 4:5 portrait source posted to a 1:1 square target gets the top and bottom trimmed; a 1:1 source posted to a 16:9 landscape target gets the left and right trimmed. The only part that is guaranteed to stay visible on every crop the platform applies is the central rectangle that intersects all of those targets - the safe area. Design within the safe area so logos, faces and headlines stay readable on every layout, then trust the platform's own crop for the rest.

What this workflow handles

Each platform defines its own feed-post aspect ratio and crops the rest off without asking. LinkedIn crops landscape share images to roughly 1.91:1; X's large summary card is the same 1.91:1 ratio but its in-timeline preview is closer to 16:9 on desktop; YouTube thumbnails are 16:9 and never get re-cropped. The safe area is the centre rectangle that survives every platform crop plus every device crop, so place text and key visual elements inside it. Outside the safe area you can use background imagery, colour washes or graphics that read at any aspect ratio. Sources for each platform's documented crop are listed in the Sources block below.

How to use it

  1. Decide the primary target - the platform whose ratio is the starting point of your design.
  2. Sketch the inner safe area first: a centre rectangle equal to the platform's shortest axis (1080 wide for a 1080 by 1080 LinkedIn square, 1080 tall for a 1200 by 628 X card, 720 tall for a 1280 by 720 YouTube thumbnail).
  3. Place logos, faces, headlines and call-to-action text inside the safe area so nothing critical is at the edges.
  4. Use the outer ring for background colour, decorative imagery or graphics that read at any aspect ratio - never put text there.
  5. Export at the exact pixel dimensions the platform documents, not the source resolution. The Social Media Image Resizer produces each platform's documented size as a single PNG.
  6. Open the exported PNG on a phone and on desktop before uploading - the device crop is the second crop you need to survive.

Frequently asked questions

What is a social media image safe area?

It is the centre rectangle of an image that stays visible after every platform-specific crop and every device aspect ratio. Anything inside the safe area is guaranteed to appear in the feed; anything outside may be trimmed. Place logos, faces, headlines and key call-to-actions inside the safe area and treat the outer ring as decorative.

Does LinkedIn crop uploaded images?

Yes. LinkedIn's help center states a 1200 by 627 pixel minimum for landscape share images (roughly 1.91:1) and a 1:1 ratio for square feed posts. The platform applies additional device-specific crops inside that envelope, so the centre of the source is the only part guaranteed to show in every LinkedIn layout. LinkedIn's image specifications are the canonical reference.

Does X (Twitter) crop uploaded images?

Yes. X's developer documentation specifies a recommended 1200 by 628 pixel image at 1.91:1 for the summary card with large image, and in-timeline previews render that file at roughly 16:9 on desktop and a square crop on mobile. Designing inside the intersection of those two crops is what keeps the subject visible on every X layout.

Does YouTube crop thumbnails?

No. YouTube recommends a 1280 by 720 pixel thumbnail at 16:9 and serves it at that ratio in search results, on the watch page and on the channel page. The platform does not re-crop the thumbnail, so the safe area is simply the centre of the 1280 by 720 source. Keep the title text and main subject inside the inner rectangle so it is readable on a phone.

How big should the safe area be?

A practical rule is the inner 80 percent of the longest dimension: design within the centre 80 percent of width and height and treat the outer 10 percent on each side as decorative. For LinkedIn and X, place any text or logo inside the centre 1080 by 1080 square of a 1200 by 627 source so the text survives a square crop on mobile. For YouTube, the inner 80 percent of 1280 by 720 keeps the thumbnail readable on a small phone screen.

Can I avoid cropping entirely?

Only on YouTube, which never re-crops a thumbnail. LinkedIn and X both crop uploaded images to their own ratio, so the only way to avoid the crop is to export each image at the platform's exact pixel dimensions before uploading - for example, a 1080 by 1080 PNG for a LinkedIn square post and a 1200 by 628 PNG for an X summary card. The Social Media Image Resizer outputs each of those exact sizes so the uploaded file already matches what the platform expects.
