As videos have become an integral part of social media marketing, estimates suggest that almost half of the marketing investment is spent on videos. With platforms releasing new video ad formats often, it can be tough to keep up. But as a marketer, you need to keep up with this info to ensure that your content looks its best.

We won’t leave you hanging after telling you the best video specs for your marketing campaigns; on the contrary, you can check out how to get more likes on Instagram after this and get going with your brand promotional efforts in full flow!


Instagram introduced video features in 2013 and saw ample traction, and began advertising in 2015. And ever since, approximately 71% of businesses use Instagram to target their customers efficiently.
Also, in Q1 2017, more than 5 million individuals watched brand-created Instagram videos. So it’s evident that Instagram investments are reaping benefits for marketers.
Instagram facilitates three kinds of video: square (1:1), vertical (9:16 or 4:5), and landscape (16:9).

If you are wondering which way to go, we’d suggest you opt for the square format. This is because they take up more space in consumer feeds than horizontal videos but do not clutter the whole screen as vertical videos do. Square videos are also more convenient for streaming on both desktops and smartphones.

  • Minimum resolution for landscape video is 600 x 315.
  • Recommended video formats are .MP4 and .MOV.
  • Frame rate range: 23-60 FPS.
  • Max file size for all formats is 4GB
  • Video length max is 60 seconds.

Limits on Characters

  • Caption maximum: 2,200 characters.
  • Recommended caption: 125 characters.
