How many posts a day does Instagram allow?
Last verified August 20, 2026 · re-checked weekly · answered from 1 verified rule
For API publishing, Instagram enforces a rolling 24-hour quota rather than a calendar-day reset. Meta's own documentation contradicts itself on the ceiling: the endpoint reference says the total is currently 50, while the Content Publishing guide says 100. Because both numbers are published and either can change, the only safe approach is to poll the quota for each account before publishing.
Meta publishes two different numbers
This is the part that catches integrators. The content_publishing_limit endpoint reference states the quota total is currently 50. The Content Publishing guide states that Instagram accounts are limited to 100 API-published posts in a 24-hour moving period.
Both pages are live, both are official, and they disagree. Hardcoding either is unsafe - not because one is wrong, but because you cannot tell which applies to a given account, and Meta can change either page.
Poll the quota, never hardcode it
The endpoint returns both the quota total and current usage for the specific account you ask about, over a rolling window of 86,400 seconds. That is the number to respect.
Call it before each publish and read what comes back for that account. A carousel counts as a single post regardless of how many images it contains, which is worth knowing if you are batching.
- The window rolls continuously - it does not reset at midnight
- A carousel counts as one post, not one per image
- Read quota total and usage per account, not once globally
- Never hardcode 50 or 100 - Meta publishes both
This is the API limit, not the app limit
Everything above governs publishing through the Graph API, which is what scheduling tools and automations use. Posting by hand in the Instagram app is a different path with no published numeric quota.
If you are hitting a wall through a scheduler, this quota is the first thing to check.

How many posts can I publish to Instagram per day via the API?
Meta publishes two conflicting figures - 50 on the endpoint reference and 100 in the Content Publishing guide - over a rolling 24-hour window. Poll the content_publishing_limit endpoint for the account you are publishing to and respect the total it returns.
Does the Instagram posting limit reset at midnight?
No. It is a rolling 24-hour window of 86,400 seconds, so capacity frees up continuously as older posts age out rather than all at once at a fixed time.
Does a carousel count as one post or several?
One. A carousel counts as a single published post against the quota regardless of how many images or videos it contains.
Why did my scheduling tool stop posting to Instagram?
Most often the account has hit its rolling publishing quota. Because Meta documents two different ceilings, a tool that hardcoded the higher one will keep trying against an account that is actually capped lower.
