For videos on Instagram, 1920x1080 will ensure that your video looks crisp and professional when watched in full screen mode. Additionally, many of the new features on Instagram such as Stories and Live Video work best with 1920x1080 resolutions due to their larger file size limitations. Whether you are shooting photos or videos for Instagram posts, using a 1920x1080 resolution setting can help maximize the impact of your content while staying within the platform's guidelines.
