Today, TikTok has rapidly become the top platform for short videos, with millions of users scrolling through endless content every day. To stand out and grab your viewers' attention, your video needs to meet TikTok's specific size requirements. If not? You need to resize your video for TikTok.
TikTok's unique format emphasizes full-screen videos, designed specifically for the platform. Videos that don’t fit well can appear awkward or low-quality, which may drive away your audience. To avoid this, we’ve created a quick guide on TikTok’s dimensions, aspect ratios, and file size requirements to make sure your video gets the attention it deserves!
In this article
Part 1. TikTok Video Sizes and Requirements
Since TikTok is optimized for mobile use, videos on the platform perform best when they are vertical and occupy the full screen. The ideal size is 1080x1920 pixels which looks great on smartphones. As for the aspect ratio, TikTok works well at 9:16 for a smooth viewing experience. This ratio helps your content fit perfectly without black bars or awkward cropping.
Moreover, it's also important to keep your video file size within TikTok's limits (500MB). Smaller files not only load quicker but also maintain better quality during playback. For your convenience, the key TikTok video requirements are summarized in the table guide below.
| Ideal Video Size | 1080x1920 pixels |
| Aspect Ratio | 9:16 |
| Max File Size Limit | 500MB |
| Video Length | 5-60 seconds |
If your video exceeds these limits or doesn't fit the required dimensions, don’t worry. You can still resize it to meet TikTok’s specifications by following the resizing guide in the next section. This will help optimize your video for better performance on the platform.
Part 2. How to Resize Video for TikTok Without Cropping Yourself
Creating content for TikTok can present several challenges, especially for creators who are repurposing videos originally made for other platforms. One common problem is that important parts of the video can get cropped out, as the vertical format requires a narrow frame. This often leads to the main subject being cut off or essential details being missed.
Additionally, creators may struggle with maintaining video quality after resizing the dimensions. Ensuring the video fits seamlessly within TikTok’s format without losing clarity or content can be tricky. This is why you have to find the right TikTok video resizer tool: Wondershare Filmora.
There are a few ways to change video size for TikTok using Filmora: Using the Auto Reframe feature, cropping your video, or adjusting the aspect ratio to meet TikTok's vertical requirements. Cropping and adjusting the aspect ratio simply focuses on resizing the video without considering its key content.
On the other hand, Auto Reframe is an advanced method that ensures the most important elements of your video remain visible. This feature uses AI technology to identify the key focus of your video and crop it to keep the main action or subject always in view and never go out of sight.
So, if you want to resize a video for TikTok without cropping yourself, here’s how to do it with Filmora Auto Reframe:
Step1Open Filmora and choose Auto Reframe
You can easily spot Auto Reframe in the AI Toolbox after opening Filmora. Click the banner and you’ll be directed to a new window to import your video.
But if you’re in the middle of editing your video, you can also access Auto Reframe by selecting the video in the timeline. Then, navigate to Tools > Auto Reframe in the Filmora editing interface.
Step2Set your ratio
Filmora offers various ratios like Widescreen (16:9), Square (1:1), Vertical (9:16), Standard (4:3), and Cinema (21:9). Since you want to resize video for TikTok, you can choose Vertical (9:16).
You can also adjust the Motion Speed option to auto, fast, or slow. Setting it to auto will automatically determine the optimal speed based on the video content.
Step3Preview your edits and Save
After having your video edited, you can preview the result by clicking Analyze. In case you still need to work on it, you can play and pause the video to move the framing box into the position you like. When you’re all set, you can move by clicking Export to save your video or Add to Timeline if you want to edit it further.
