What is Instagram Story's video size limit?
Upload your video to CompressYourVideo.com, select Instagram Story, and download the compressed version. CompressYourVideo.com automatically optimizes your video to fit within Instagram Story's size limit with the best possible quality.
Instagram Stories are the ephemeral 24-hour format that made vertical video mainstream. Each Story segment is up to 15 seconds, displayed full-screen in 9:16 vertical format, and disappears after 24 hours unless saved to Highlights.
How Stories differ from Reels
Stories and Reels are both vertical 9:16 formats, but serve different purposes. Stories are for casual, in-the-moment content: behind-the-scenes, quick updates, polls, Q&As. Reels are for polished content designed to reach new audiences through Instagram's discovery algorithm. Stories only show to your existing followers.
The 15-second segment rule
Instagram splits videos longer than 15 seconds into multiple 15-second segments. A 45-second video becomes 3 Stories. Some creators use this deliberately, cliffhangers between segments keep viewers tapping through. But most Story content works best as a single 15-second clip.
