Best Size for Instagram Reels
1080 x 1920 pixels with a 9:16 aspect ratio is what you should be aiming for in 2024.
This sizes ensures that your Reel’s perfectly visible on any screen size (e.g. PC, iPhone, iPad etc).
1. Size Ratio
- 9:16 if viewed in full-screen
- 4:5 if viewed in the Instagram newsfeed
It really depends on where Instagram shows your Reels — ultimately, that’s not up to you, but rather to the Instagram Algorithm.
2. Frame Size
- 1080px wide
- 1920px high
Only use Vertical videos for your Reels — never go for horizontal videos, as they’re the exact opposite of Instagram Reels’ purpose.
Horizontal videos often get badly cropped (automatically, by Instagram).
3. Cover Size
- 1080 x 1920 pixels
- 9:16 aspect ratio
The cover of is what people see on your IG profile’s “Reels” section” before tapping to watch the Reel.
Important: Covers can’t be edited/changed after the Reel is live.
4. Thumbnail Size
- 1080 x 1080 px
- 1:1 aspect ratio
Thumbnails are shown in your FEED, not under the ‘Reels’ section → that’s why they’re square images, just like any other Instagram post.
While they may sound similar, they’re two different images.
5. Safe Area
- 1080 x 1350 pixels
- 4:5 aspect ratio
This is because at the top, bottom and right side of your screen are Instagram’s Interface Elements.
e.g. Likes, comments, Shares, caption, user’s profile.
6. Captions Length
- Limited at 2,200 characters
- Doesn’t allow links (URLs)
However, you’re not going to need a long captions — even though we’ve seen a couple of trends in the summer of 2024 where people had super long captions.
A notable example is the classic “The Mercedes CLR GTR” caption which randomly described one of Mercedes-Benz‘s super powerful cars in posts that were unrelated (e.g. memes or any kind of funny video).
7. Reel length
- Recorded on Instagram: 90 seconds
- Uploaded videos: 15 minutes.
If you hold the ‘record’ button, Instagram allows you to record for max. 90 seconds.
However, if you’re editing and scheduling posts with SendShort, your limit is now huge, at 15 minutes.
