Instagram video sizes, dimensions, and formats for 2025

Instagram video has quickly become one of the most sought-after platform features. From Instagram Stories to Reels, carousel posts, and more, there are so many ways to tell a visual story. Whether you’re focusing on video content or engaging with Instagram users, it’s important to know how to get the most out of your video posts.

While Instagram videos are popular, not every video makes it to the front page. Different videos serve different purposes, and as a result, have different specs. If you want your videos to perform well, you need to do things by the books! This means paying attention to video dimensions and sizing requirements for each type of video.

There are currently four different Instagram video formats on Instagram. These are:

• Instagram Reels
• Instagram Stories
• In-Feed Carousel videos
• Instagram Live videos

In this post, we’re going to break down everything you need to know about Instagram video sizes, video resolution, file formats, and video file types in 2025. This will keep your visual stories looking their best, so you can spend more time winning the algorithm.

Instagram video sizes

Instagram Reels video size

Instagram Reels are designed to be viewed full-screen, vertically, and on mobile devices. With that in mind, the best way to make sure your Reels are the correct size is to shoot and edit your video posts directly on your phone.

Whether you’re shooting for Instagram feed videos or longer content, maintaining the right video resolution ensures you stand out — so focusing on the ideal size is key.

Instagram Reels video guidelines are:

• Size and dimension: 1080 by 1920 pixels
• Frame rate: 30 FPS
• Max file size: 4GB
• Aspect ratio: 1.91:1 and 9:16
• Video length: 3 seconds to 15 minutes. (However, in-app recording is limited to 90 seconds, though users can upload videos up to 15 minutes)
• Recommended video formats: MP4, MOV
• [Optional] Bitrate: Use a high-quality video codec such as AAC for better audio output

Note: In-feed videos are now considered Reels. This means that any video posted directly to your Instagram feed will automatically be categorized as a Reel, even if it’s not recorded through the Reels feature.

So, when you’re uploading to your feed, make sure your video meets the Reels size requirements of 1080px by 1920px and follows the same specs as traditional Instagram Reels.

This change gives your videos access to the same features, discoverability, and algorithm boosts as standalone Reels!

Tip: Don’t forget to leave some room at the bottom of your Reel for the video caption! The bottom fifth of the screen is where the caption will be displayed.

Instagram Stories video size

Instagram Stories have pretty much the same size requirements as Instagram Reels. Most Reels are shot using the Instagram app to make use of effects, transitions, and music.

Instagram Stories video guidelines are:

• Size and dimension: 1080 by 1080 pixels
• Minimum width: 500 pixels
• Frame rate: 23-60 FPS
• Max file size: 4GB
• Aspect ratio: 9:16
• Video length: 1 to 60 seconds
• Recommended video formats: MP4, MOV, or GIF

Remember, the Instagram video size limit for Stories is 4GB for every 15 seconds of video. So, if your Story is more than 15 seconds long Instagram will split it up into 15-second blocks. Each of those blocks can be up to 4GB.

Instagram carousel video size

Instagram Carousel videos are a great way to showcase multiple pieces of content in a single post, whether it’s a product launch, some behind-the-scenes footage, or a step-by-step tutorial. Here’s everything you need to know to make sure your carousel posts fit perfectly.

Instagram Carousel video guidelines are:

• Size and dimension: 1080 by 1080 pixels, 1080 by 1350 pixels
• Frame rate: 23-60 FPS
• Max file size: 4GB
• Aspect ratio: 9:16
• Video length: 3 seconds to 60 minutes
• Recommended video formats: MP4, MOV

PSA: Instagram doesn’t consider carousel videos to be Reels. So, while they give you the flexibility to add multiple videos in a swipeable format, they won’t appear in the Reels tab and don’t come with the same features.

Instagram Live video size

Instagram Live video lets users broadcast in real-time, providing an interactive way to engage with your audience. It’s perfect for Q&As, behind-the-scenes content, or connecting with your followers during events.

Here are the some sizes and specs to make sure your Instagram Live video runs smoothly.

Instagram Live video guidelines are:

• Size and dimension: 1080 x 1080 pixels
• Time length: Up to 4 hours
• Aspect ratio: 9:16
