Instagram and TikTok daily posting limits

How many posts can you schedule on Instagram and TikTok a day?

Through a scheduling tool, Meta's guide sets Instagram at 100 API-published posts per moving 24 hours (it says 50 in one section, so plan for 50), with a carousel counting as one. TikTok caps API posts per account each day but doesn't publish the number. Spread posts out to stay under both.

Instagram limits for scheduled posts

Daily cap: 100 API-published posts in a moving 24-hour window, per Meta's content publishing guide. The same page says 50 in its carousel section.
A carousel counts as one post and holds up to 20 photos or videos. Every image is cropped to the first one's ratio, 1:1 by default.
Reels: 3 seconds to 15 minutes, up to 300 MB, 23 to 60 fps, 9:16 recommended.
Stories: up to 60 seconds and 100 MB per video.
Images: JPEG only, up to 8 MB, between 4:5 and 1.91:1.
A post prepared for publishing expires if it isn't published within 24 hours.
Publishing through the API needs an Instagram professional account.

How the 24-hour window works

The window moves rather than resetting at midnight: each post counts for 24 hours after it goes out. Tools can ask Instagram how much of the allowance is used. If yours shows a daily-limit error, wait for the oldest post in the last 24 hours to drop out, or move posts to the next day.

TikTok limits for scheduled posts

Daily cap: TikTok limits how many posts each account can send through its API in a day, but doesn't publish the number. When it's reached, tools get a "too many posts" response (spam_risk_too_many_posts).
Requests: 20 a minute per account's access token.
Length: up to 10 minutes through the API. Each account also has its own maximum, which TikTok reports to the tool before posting.
Video files: MP4 (recommended), WebM or MOV, H.264 recommended, up to 4 GB, 360 to 4,096 pixels on each side, 23 to 60 fps.
Photos: JPEG or WebP, up to 20 MB and 1080p.
Audience: the choices a tool can offer (everyone, friends, followers, only me) depend on the account's own privacy settings.
New apps: until an app passes TikTok's audit, everything it posts is private. If a tool's TikTok posts only show to you, that's the likely reason.

Daily caps on the other platforms

Platform	Posts per 24 hours through the API	Longest video
Instagram	100 (50 in one section of the same guide)	15 min (Reels)
Facebook Page reels	30	90 s
Threads	250	300 s
TikTok	A cap per account; the number isn't published	10 min, or less if the account's maximum is lower
YouTube	A daily upload limit that varies by country or region and channel history	Shorts up to 3 min; 15 min until the account is verified

YouTube Shorts rules worth knowing

Shorts can be up to 3 minutes, square or vertical. Wider videos count as regular videos.
A Short longer than one minute with an active copyright claim is blocked until the claim is resolved.
Accounts can upload videos up to 15 minutes until they're verified.

How to stay under the limits

Spread posts through the day instead of sending a batch at once.
On Instagram, use a carousel for a set of photos: it counts as one post.
Use one tool per account. Two schedulers posting to the same account share its daily allowance.
If TikTok says "too many posts", move the post to tomorrow; sending it again straight away won't help.

The easier way

Socialhand makes one new idea a day on Starter, 3 on Growth, and 3 for each of up to 2 brands on Pro, each turned into a post for all 8 platforms and scheduled for you.
Every post is checked against its platform's limits before you can approve it: caption length, hashtags, video length and carousel size. Anything that breaks a limit is flagged so it's fixed before it's scheduled.
If a platform still refuses a post, it's marked as failed with the platform's reason in your calendar, and the morning email says how many posts failed that week.
Plans start at $97 a month for all 8 platforms, and you can try it free first.
