Absolutely! Instagram will let you choose your video either in the 16:9 widescreen format (aka “the Landscape Video Ad” discussed in this article) or the square 1:1 format. Instagram can accommodate your video in the typical 16:9 (1920 x 1080) or 1:1 ratio (1080 x 1080) respective to the widescreen or square format. In reality, Instagram automatically adjusts your video’s size according to the device being used.
