Formats and limits
What PostSider actually publishes to Instagram
Instagram is not one format with one set of rules. The publishing API treats a Story, a Reel and a carousel differently, and most failed posts come from composing for one and scheduling as another. These are the rules the integration enforces before a post leaves the calendar.
| Post type | Media rule | What changes in the composer |
|---|---|---|
| Feed post | At least one image or video, up to ten attachments | Caption up to 2200 characters, optional collaborators |
| Carousel | Two to ten images, published as one post | The first image is the cover in the feed |
| Reel | One video | Trial Reels accept a single video and use the account graduation strategy |
| Story | One image | Stories take no carousel and no second attachment |
How the weekly plan works
The calendar is the working surface. You drop a week of posts onto it, each with its own type and media, and the per-network preview shows how the caption and the crop land before anything queues. That preview is where most Instagram mistakes are caught: a vertical image that will be cropped in the feed, a caption that runs past the 2200 character ceiling, or a Story scheduled with two attachments.
Publishing is a separate step from scheduling, and the status is separate from both. After the planned time, read the post and open the published version. A queued item is work pending, not a delivered post. When Instagram rejects an upload, the error stays on that target while the other networks in the same group continue.
The API enforces a limit of 25 posts per day per Instagram account. A calendar can hold more than that, so a batch of Stories plus feed posts plus Reels needs a spread across the day rather than one burst at 9 a.m.
What Instagram scheduling costs
Two comparisons matter here: the platform-native option, which is free, and the per-channel schedulers, which price each connected network. The table below uses verified figures from the vendors' own pricing pages on 30 October 2026.
| Plan | Price | What you get for Instagram |
|---|---|---|
| Buffer Essentials | $5 per channel / month | One Instagram channel, one user, unlimited scheduled posts |
| Buffer Team | $10 per channel / month | The same channel with unlimited users and approvals |
| Later Starter | $18.75 / month, billed yearly | One social set of eight profiles, one user, AI credits separate |
| PostSider Standard | $20 flat / month | Five channels including Instagram, one seat, API, MCP and SDK |
| PostSider Team | $35 flat / month | Ten channels, unlimited seats, approvals, unlimited posts |

What PostSider does not do on Instagram
- No DM or comment inbox. Replies and community work stay in the Instagram app.
- No AI image generation and no caption generator. The post checker flags a caption over the limit and can rewrite it.
- No RSS auto-posting, and no automatic repost of evergreen content without a queue you set up.
- No guarantee that Instagram accepts a file. Media processing happens on Meta's side after upload.
Where this fits
A small team that publishes a few Instagram posts a week usually lands on the small business workflow, which fills a week in one sitting. A store announcing drops needs the ecommerce profile, where the media library and per-network previews matter more than approvals. If you are leaving a per-channel tool, the Buffer alternatives comparison does the seat and channel maths. Plan limits are on the pricing page.
Why use it
Instagram scheduling without another isolated workflow.
Use the same calendar, approvals and publishing workflow you already use for the rest of your social stack.
Write an Instagram-specific caption instead of pasting the same text everywhere, and check it against the 2200 character ceiling before it queues.
Let a shared calendar cover the weekly plan, while a script or an agent can publish the same kind of post through the API when the volume grows.
Workflow
From draft to published in one queue.
Connect a professional Instagram account
Instagram publishing needs a business or creator account connected through Meta. A personal account cannot publish through the API, so convert it first if the account is still personal.
Choose the post type before the caption
A feed post takes one to ten images, a carousel is the same multiple-image path, a Reel takes one video, and a Story takes one image. Pick the type first, because the media rules change with it.
Preview, schedule, then verify the result
Look at the per-network preview before the post queues. After the publishing time, read the post status and open the published post. A scheduled item is not proof that Instagram accepted it.
Humans + AI agents
Use the calendar yourself or publish programmatically.
PostSider exposes the same social publishing workflow through MCP, REST and an SDK, so automations and AI agents can work alongside your team.

FAQ
Instagram scheduling, answered.
What is an Instagram scheduler?
A scheduler holds a queue of Instagram posts and publishes them at planned times. PostSider takes feed posts, carousels, Reels and Stories from one calendar, so the Instagram plan sits next to the other networks instead of in a separate tab.
How do I schedule Instagram posts with PostSider?
Connect a business or creator account through Meta, create a post, choose the media and the type, write up to 2200 characters, then pick a date and time. The post appears in the calendar with a per-network preview before it publishes.
How many images can an Instagram carousel have?
Up to ten. PostSider enforces the same ceiling the Instagram API enforces, so an eleventh attachment is rejected before publishing rather than after a failed upload.
Can I schedule Instagram Stories and Reels?
Yes. A Story takes one image, and a Reel takes one video. Trial Reels are supported as a single video with the graduation strategy the account uses, so the post reaches the existing audience before it is promoted.
Why do I need a business or creator account?
The Instagram publishing API is only available to professional accounts. A personal account has no publishing endpoint, which is why every scheduler asks you to convert before connecting.
Is an Instagram scheduler cheaper than scheduling natively?
Native scheduling inside Instagram is free and fine if Instagram is your only network. PostSider starts at $20 per month for five channels and exists for the case where one team publishes to Instagram plus several other networks from one calendar.
What does PostSider not do on Instagram?
There is no DM or comment inbox, so replies stay in the Instagram app. There is no AI image or caption generation beyond checking and rewriting a caption you wrote, and no auto-posting from an RSS feed.
