💡 Pro Tips

  • • Always use PNG for graphics with text, JPEG for photos
  • • Keep important content in the center (safe zone) for cropping
  • • Use 72-96 DPI for web, higher resolution files are compressed anyway
  • • Test your images on mobile before posting. Most views are on phones
  • • Save templates at the recommended sizes for quick content creation

Frequently asked questions

What image size should I use for each platform?

For feed posts, 1080 x 1350 (4:5 portrait) is the strongest default on Instagram, Facebook and LinkedIn because it occupies the most vertical space on a phone. Stories and Reels use 1080 x 1920 (9:16), and YouTube thumbnails use 1280 x 720 (16:9).

Why does Instagram crop my image?

Because the image ratio does not match a supported one, so it is cropped to the nearest fit. In a carousel the first slide sets the ratio for every slide after it, which is the usual cause of a set that looks correct individually and cropped once posted.

Do I need a different image for every platform?

Not usually. A single 4:5 portrait design covers Instagram, Facebook and LinkedIn feeds. You only need a second export for 9:16 vertical formats such as Stories, Reels and TikTok.

How large can the image file be?

Instagram accepts up to 8MB per image, Facebook up to 30MB and LinkedIn up to 10MB for feed images. All of them recompress on upload, so exporting far above these limits gains you no quality.
