How this free Instagram Story scheduler works

Upload a 9:16 photo or video Story, add an optional caption, and pick a publish time. Postmixr publishes via the Instagram Graph API so Stories go live without manual posting.

Instagram Story size and duration

Stories use a 1080×1920 (9:16) canvas. Video segments can be up to 15 seconds per frame. Keep text and CTAs inside the safe zone — avoid the top and bottom edges where UI overlays appear.

Tips for scheduling Instagram Stories

Queue Stories at consistent times (morning check-ins, end-of-day recaps) to stay top-of-mind. Pair scheduled feed posts and Stories on launch days for maximum visibility.
