Scheduling Instagram Posts, Reels and Stories
Learn how to schedule Instagram feed posts, Reels, carousels, and Stories through Publlish. Understand auto-publishing vs. notification publishing, what's supported, and how to avoid common Instagram scheduling errors.
Instagram has more content formats than any other platform Publlish supports — and each format behaves differently when it comes to scheduling. This guide covers how to schedule every Instagram format, what auto-publishes vs. what requires a manual step, and how to avoid the most common Instagram scheduling issues.

Scheduling Instagram Feed Posts and Carousels
Feed posts — single images, single videos, and carousels — are fully supported for auto-publishing through Publlish.
To schedule a feed post:
- Click New Post and select your Instagram account
- Upload your image or video — check that it meets Instagram's aspect ratio requirements Instagram aspect ratio guide →
- Write your caption — first 125 characters are visible before the "more" cutoff
- Add hashtags, location tag, and mentions as needed
- Set your scheduled time and click Schedule
Publlish will publish automatically at the scheduled time.
For carousels: Select multiple images in the media uploader. All slides must use the same aspect ratio — mix of ratios will cause Instagram to crop them all to match the first slide.
Scheduling Instagram Reels
Reels are fully supported for auto-publishing.
To schedule a Reel:
- Click New Post and select your Instagram account
- Upload your vertical video (9:16, 1080 x 1920px, under 90 seconds, MP4)
- Write your caption
- Optionally add audio from Instagram's music library
- Set your scheduled time and click Schedule
Reels publish automatically at the scheduled time.
Safe zones: Instagram overlays the caption, audio name, and profile information over parts of the Reel. Keep important visual content in the centre of the frame to avoid it being covered by UI elements.
Scheduling Instagram Stories
Stories work differently from feed posts and Reels — they use notification publishing rather than auto-publishing.
How it works:
- Schedule your Story in Publlish as normal — upload your image or video and set a time
- At the scheduled time, Publlish sends a push notification to your phone via the Publlish mobile app
- You tap the notification, the Publlish app opens with your Story content ready
- Publlish hands off to the Instagram app where you complete the posting
Why Stories can't auto-publish: Meta's API does not currently allow third-party tools to publish to Instagram Stories automatically — the final publishing step must be completed in the Instagram app. This is a Meta platform limitation, not a Publlish limitation.

Requirements for notification publishing:
- Publlish mobile app installed on your phone
- Push notifications enabled for the Publlish app
- Instagram app installed on the same device
Why Your Instagram Posts Might Not Be Auto-Publishing
If your Instagram posts aren't going live automatically at the scheduled time, the most common causes are:
1. Personal Instagram account Auto-publishing only works with Business or Creator accounts. Personal accounts are not supported. Switch to a Business account →
2. Facebook authorisation incomplete Instagram's API requires Facebook authorisation. If this wasn't completed during setup, auto-publishing won't work. Reconnect your Instagram account and ensure all permissions are granted. Connecting Instagram →
3. Expired connection token Instagram connections expire and need periodic refreshing. Refresh your channel →
4. Media spec error Your image or video doesn't meet Instagram's requirements. Check aspect ratio, file format, and file size. Instagram aspect ratios →

Instagram Scheduling Best Practices
Schedule Reels consistently. Reels currently receive the highest organic reach on Instagram. Aim for 3–5 Reels per week, scheduled during your audience's peak activity hours.
Use the Grid Preview before finalising your schedule. Check how upcoming posts look on your profile grid to maintain visual consistency. Instagram Grid Preview →
Schedule Stories separately. Since Stories use notification publishing, plan for the manual completion step. Don't schedule Stories for times when you can't be at your phone.
Post feed content at your audience's active times. Check your Instagram Insights for when your followers are most active — Publlish's analytics can also show this data.
