What matters
Instagram IGTV Cover dimensions at a glance
IGTV cover images display at 420×654 in the IGTV channel tab. In the main feed, they may be cropped closer to square, so the design needs to work at multiple ratios.
A well-designed IGTV cover turns the video tab from a wall of random frames into a cohesive, clickable channel — especially for brand accounts with series content.
Auto-selected frames look unprofessional and make it hard for viewers to find specific content. Text placed at edges gets cropped in feed previews.
