Size Guide 2026: Social Media Ad Formats

In the world of digital marketing, "one size fits all" is a myth that can cost you money. You wouldn’t put a billboard in a magazine, and you shouldn’t put a horizontal landscape photo in a vertical Instagram Story.

To stop the scroll, your creative needs to feel native to the platform. Here is your definitive guide to the different formats and sizes you need to produce for a high-performing campaign. 

1. Image sizes

Because users toggle between platforms and placements (e.g., the Feed and Stories), you need a multi-asset approach. Visuals should be delivered in jpeg.

  • The Square (1:1): * Size: 1080x1080px
  • The Portrait (4:5): * Size: 1080x1350px
  • The Full Vertical (9:16): * Size: 1080x1920px
  • The Landscape (1:91:1): * Size: 1200x628px

2. Video sizes

  • YouTube Shorts/ Reels / Stories (9:16): * Size: 1080x1920px
  • Standard Video (16:9): * Size: 1920x1080px
  • Square Video (1x1): * Size: 1080x1080px
