How to Resize a Video for Social Media

Video content is trendier than ever on social media platforms. Video has always been a powerful tool for human expression and communication.

Creators have been leveraging the power of video for Instagram, Youtube, TikTok, and other platforms for years. In fact, more than half of all digital marketers say video is the most important content type.

Even so, video content is still widely underutilized. Videos make up less than 18% of content on Instagram, Facebook, and Twitter, despite their marketing benefits.

One of the most challenging aspects of consistently posting videos across platforms is resizing your video to fit various video formats.

Resizing videos can be an aggravating task. But with the right steps and tools, it’s quick and easy.

In this blog post, we’ll cover some different video sizes for social media channels and give you a step-by-step guide on how to easily resize videos for any social media post.

Why Resize Video Content for Social Channels?

Each social media platform has its own unique video requirements, like aspect ratio, resolution, and duration. By resizing your videos, you maximize reach across all your social channels. If you're already putting in the effort to create original content , you should also make sure it reaches a wide audience.

Optimizing your video for all platforms allows you to repurpose video and post in other places. This makes for a smoother user experience across all social channels. By posting the same content on all platforms, it’s easier to maintain your brand’s cohesiveness on social media.

It's also important to resize videos so that they fit each app's unique features. TikTok and Instagram favor vertical video. On the complete opposite end, Youtube and Facebook use horizontal formats. If your video doesn’t fit the preset sizes on the platform you post to, it’ll either fail to post or crop the video. By not resizing, you risk cutting the video off or making the video experience clunkier.

Video Sizes for Social Media Platforms

Each platform has different video formats, but keeping track is tricky. How do you resize a video for Instagram vs resize a horizontal video for YouTube? To make it simpler, we’ve broken down the specs of four different social media sites. Note that the sizing standards will differ for different kinds of posts. For example, the size of videos for Instagram stories may be different than that for Instagram Reels. To make video editing for size easier, be sure to research your specs before editing. Sprout keeps an up-to-date Google Doc with everything you need to know on resizing for multiple platforms.


Instagram offers three different video sizes: landscape, portrait, and square. When resizing for Instagram, use a vertical aspect ratio.


Since Meta owns both Instagram and Facebook, it’s easy to cross-post on both platforms. You can post to your Instagram and Facebook reels without having to change the size. However, Facebook’s video are usually landscape-oriented.


Tiktok is another mobile-oriented platform that uses vertical video. It’s a great app for repurposing longer content into multiple smaller videos.


As the second largest search engine after Google, YouTube is a great platform for exposure and engagement. The addition of YouTube Shorts also allows you to upload short videos similar to TikTok. Here’s what to know for a YouTube video:
