You can post up to 20 photos and videos in one Instagram post. Instagram doubled the limit from 10 to 20 in August 2024, and the 20 slots can be photos, videos or a mix. There is no published limit on how many posts you can share in a day, and each photo you add to Stories becomes its own story.
PostEverywhere schedules Instagram carousels of up to 10 images, plus single photos, Reels and Stories, so your posts go out at the times your audience is online. See how it works.
So that's the limit. How many photos should you actually use? We looked at 1,000+ Instagram carousels scheduled with PostEverywhere, and carousels of 7 to 10 slides did best: 17% better than the same account's usual post.
How many pictures can you put in an Instagram post?
Up to 20. A single Instagram post, also called a carousel, holds up to 20 photos, videos or a mix of both. Before August 2024 the limit was 10, which is why older guides and some Reddit threads still say 10 or 15 (Instagram tested 15 for a while before settling on 20).
How many photos can you post on Instagram?
The limits that matter for each kind of post, checked against Meta's own pages and launch coverage.
- One postUp to 20 photos
- Photos, videos or a mix, in one carousel
- Doubled from 10 in August 2024
- You can reorder slides later, not add new ones
- Scheduled with PostEverywhereUp to 10 images
- Per carousel, set up ahead of time
- Our data: 7-10 slides did best
- Single photos, Reels and Stories too
- Per dayNo daily cap in the app
- Instagram publishes no daily post limit
- Through Instagram's API: up to 100 posts a day
- A carousel counts as one post
- StoriesOne photo per story
- Each photo or video is its own story
- Each disappears after 24 hours
- Keep them with Highlights
- ReelsOne video
- A Reel is a single video
- Want many photos? Use a carousel
- Or turn photos into a video first
- HashtagsUp to 5 per post
- Rolling out since December 2025
- Applies to posts and Reels
- Choose fewer, more specific tags
A few rules that come with the 20:
- Photos and videos share the same 20 slots. It can be 20 photos, 20 videos or any mix.
- Every slide takes the shape of the first one. Meta's developer documentation says carousel images are cropped based on the first image, so pick the first slide's shape (square, 4:5 portrait or 3:4) with the whole set in mind. Our Instagram aspect ratio guide has the exact sizes.
- You can reorder slides after posting, but you can't add new ones. Instagram now lets you long-press and drag to change the order of a published carousel. To add another photo, you need a new post.
| What you're posting | How many photos |
|---|---|
| One feed post (carousel) | Up to 20 photos and videos |
| A carousel scheduled with PostEverywhere | Up to 10 images |
| Feed posts per day | No published limit in the app |
| Posts per day through Instagram's API | Up to 100 (a carousel counts as one) |
| Stories | One photo or video per story, each lasting 24 hours |
| Reels | One video per Reel |
| Hashtags per post | Up to 5 |
Why can't I post 20 photos on Instagram?
If the photo picker stops you at 10, one of these is usually why:
- Your app is out of date. The 20-slide limit rolled out from 8 August 2024, gradually, so older versions of the app may still stop at 10. Update Instagram and try again.
- You're using another app or tool. Some scheduling and editing apps have their own carousel limits. PostEverywhere schedules up to 10 images per carousel; if you need 11 to 20, post that one from the Instagram app.
- You're adding to a post that's already live. Instagram doesn't let you add new photos to a published carousel. Post a new carousel instead.
Can I post more than 20 photos on Instagram?
Not in a single post. If you have more than 20 photos, you have four good options:
- Split them into two or more carousels. Post part one and part two a day apart, so each gets its own reach instead of one long post that most people never finish.
- Put several photos on one slide. A collage or a split image lets you show more in fewer slides.
- Turn the photos into a video. A Reel is a single video, so a photo slideshow edited into one video lets you share far more than 20 images.
- Use Stories. Each photo becomes its own story, so Stories suit a big set of behind-the-scenes shots.
How many photos should you post in a carousel? Our data
Twenty is the limit, but it isn't a target. In PostEverywhere's Instagram Format Study 2026 we compared each carousel with the same account's usual post, so a big account can't skew the result.
In numbers: against the same account's usual post, carousels with 2-3 slides did +5% (early data), 4-6 slides +13% and 7-10 slides +17%, based on 1,000+ Instagram carousels scheduled with PostEverywhere.
- 7 to 10 slides did best: 17% better than the account's usual post (based on 500+ carousels).
- 4 to 6 slides: 13% better.
- Carousels as a whole did 13% better than the account's usual post, about level with Reels (14% better). Single photos came in just under the usual post.
Our data stops at 10 slides because that's the most PostEverywhere schedules in one carousel, so we can't tell you whether 15 or 20 slides do better still. What it does show is that a full 7 to 10 slide carousel beats a short one.
For slide-by-slide advice, read our Instagram carousel best practices, and for timing, the best time to post carousels.
Schedule your Instagram carousels ahead of time. PostEverywhere publishes carousels of up to 10 images, single photos, Reels and Stories at the times your audience is online. See the Instagram scheduler.
How many photos can you post on Instagram at once?
In one post, up to 20. If you mean how many separate posts you can share in a day, Instagram doesn't publish a daily limit for posting from the app.
Tools that publish through Instagram's official API, PostEverywhere included, are allowed up to 100 posts per account in a rolling 24 hours, and a carousel counts as one post.
You'll never come near that in practice. The more useful question is how often to post. In PostEverywhere's Posting Frequency Study 2026, Instagram accounts that posted more each week got more total results each week, while each post did only slightly worse.
See how often to post on social media for the numbers.
How many photos can you put in an Instagram Story or Reel?
Stories: each photo or video you add becomes its own story, shown one after another, and each disappears after 24 hours unless you save it to a Highlight. To share a lot of photos, add them as separate stories.
Reels: a Reel is one video. To get many photos into a Reel, edit them into a single video first. If you want people to swipe through photos at their own pace, a carousel works better.
You can also test a Reel on people who don't follow you yet with a trial reel, which PostEverywhere can schedule too.
How many hashtags can you use on Instagram?
Up to 5 per post. Instagram started capping captions on posts and Reels at five hashtags in December 2025. Pick a few specific ones rather than broad tags; our hashtag generator helps.
How to schedule multiple Instagram photos with PostEverywhere
Posting by hand means picking the photos, writing the caption and remembering to post at the right moment. PostEverywhere does the last two for you:
- Connect your Instagram account. You need a professional account (Business or Creator), which Meta requires for scheduled posting. Switching is free in Instagram's settings.
- Create the post. Add up to 10 images for a carousel, or one photo, a Reel or a Story. Write the caption yourself or with AI Studio, and customise it for Instagram if you're posting the same content elsewhere.
- Pick a time. Choose a slot yourself, use best-time suggestions, or drop the post into your posting queue so the week fills evenly.
- Or schedule a batch. Bulk scheduling takes a CSV of up to 200 posts at once, with carousel images listed by filename.
Let your AI agent schedule them. Ask Claude or ChatGPT to turn a folder of photos into a week of Instagram carousels and schedule them through PostEverywhere. Connect your AI agent.
How we worked this out
The limits in this article come from Meta's own developer documentation and from launch coverage of each change; every source is listed below. The carousel figures come from PostEverywhere's Instagram Format Study 2026: Instagram posts scheduled with PostEverywhere between December 2025 and October 2026, each scored against the same account's usual post, counting only posts whose results we read at least 3 days after publishing.
Groups with fewer than 20 accounts or 300 posts aren't reported.
