What are aspect ratios for videos?
An aspect ratio is the relationship between a video or image's width and height. Two numbers typically express an aspect ratio, like 16:9 or 9:16, representing the shape of the frame or screen. The 9:16 aspect ratio is perfect for vertical videos on mobile platforms like TikTok, Instagram Reels, and YouTube Shorts.
Choosing the proper aspect ratio for your videos is important because it ensures your content appears correctly on the intended platforms without cropping or distortion.
Captions' AI automatically adjusts your clips to the appropriate aspect ratio, so all your videos look professional. You can create one video for multiple platforms or repurpose a TikTok for an Instagram Reel, and vice versa. Choose an aspect ratio and editing style, and watch AI create social media-ready videos in minutes.
What’s the best video size for TikTok?
The best video size for TikTok is a vertical 9:16 aspect ratio with an HD resolution of 1920x1080 pixels. This format makes your content look great on smartphones and takes full advantage of TikTok's screen space.
Captions' Vertical Video Editor helps you create, adjust, and share videos according to these exact dimensions so they’re optimized for TikTok and other social media platforms. Instead of re-editing content, use Captions to save hours of manual work and make a single, multi-purpose video for TikTok, Instagram Reels, and YouTube Shorts.
You can also choose between "Fill," "Fit," and "Auto" when scaling and fitting content.
- The Fill option scales your video to cover the screen. If the video's aspect ratio doesn't match the screen, Captions will crop parts of the video to accommodate it.
- With Fit, your video will resize to fit entirely within the screen. If the aspect ratio differs, you'll see black bars on the left and right sides to avoid cropping the video.
- The best option is Auto, where Captions' AI automatically fills the frame while intelligently centering the most important parts of the video.
