Social media image sizes, all in one place

Instagram

  • Square feed post — 1080x1080
  • Portrait feed post — 1080x1350 (recommended; it fills more of the screen)
  • Stories and Reels — 1080x1920

YouTube

  • Thumbnail — 1280x720 (under 2MB)
  • Channel art — 2560x1440 (safe area in the centre is 1546x423)

Resize images by entering a width or height, scaling by percentage, or picking a social media preset. The format can stay exactly as it was.

  • In-article images — twice the column width (usually around 1600px)

The fastest way to match a size

The Image Converter NOW resize tool has all of the sizes above ready as presets. The aspect ratio is kept by default so your image is never squashed, and you get a quality warning if a setting would enlarge the image beyond its original size.

If the same image is going to several platforms, make it at the largest size (1080x1350, say) and let each platform scale it down — that gives the better result.
