2024 TikTok Video Size Guide (Best Aspect Ratio, Dimension)

By Cecilia Hwung | Last Update:

Since its debut in 2017, TikTok knew how to work with the social media growth playbook and soon made itself one of the video-sharing giant apps, penetrating 1 billion monthly active users at present. To catch up with its rivals and cover more needs of users, TikTok keeps updating its upload rules and starts to support longer videos (up to 10 minutes) this year.

However, it's hard to explain TikTok video size in one word because it varies on iOS, Android, and desktop. In this post, we'll reveal everything about TikTok size, including TikTok video file size, maximum video length, dimensions/resolution, aspect ratio, and file type. Let's begin.

TikTok Video Size Required on App Version

It's hard to say that TikTok brings short-form vertical videos to us or short vertical videos take over TikTok, but they have affected our ways of viewing for sure. TikTok displays vertical (or portrait) videos in full screen and thus makes them more immersive. On top of that, there are many more requirements for uploading videos to the mobile app of TikTok. Check them now.

  • Video Aspect Ratio: The standard aspect ratio for TikTok video is 9:16. 1:1 and 16:9 videos are also allowed but they won't fit the full screen.
  • Video Dimensions: Videos for TikTok app should be 1080×1920 for the best result. Vertical videos are recommended and TikTok will add black bars to horizontal videos.
  • Maximum video length: The latest TikTok app supports videos up to 10 minutes when uploading from local gallery and up to 3 minutes for video capturing.
  • File Size: TikTok for iOS supports videos up to 278.6MB, while the maximum file size of a TikTok video on Android smartphone is only 72MB.
  • Video Format: MP4, MOV (H.264)

TikTok Video Size Required on Web Version

ByteDance released the web version of TikTok in 2021. Despite the larger screen of the desktop, the web version of TikTok displays videos in the same way as its mobile version. But it's not exactly a copy and there are some differences in TikTok video size as follows.

  • Video Aspect Ratio: 9:16 is the recommended aspect ratio on TikTok. Videos at 1:1 or 16:9 will be presented with black bars.
  • Video Dimensions: 720×1280 or higher. But note that, videos of higher resolutions, e.g. 4K, will be compressed by TikTok, and thus may not deliver an ideal visual experience like the original video.
  • Maximum video length: TikTok allows longer videos, but this option hasn't been rolled out on its web version. The maximum duration of a video is 3 minutes on the desktop.
  • File Size: The web version of TikTok allows uploading videos under 1GB from your PC and Mac.
  • Video Format: MP4 (H.264), WebM (VP8)

How do you make a video full screen on TikTok?

TikTok plays 9:16 videos on full screen, so you can make your video at such aspect ratio by rotating horizontal video to vertical or adding background to the top and bottom sections of the video.

Is TikTok getting 10-minute videos?

Yes. If you update TikTok, you'll receive a notification that you can upload videos up to 10 minutes long from your device.

Can you upload 4K to TikTok?

Yes, but TikTok will compress 4K (YUV 4:2:0) to 1080p (YUV 4:2:2) and cause severe quality loss. To get HD video on TikTok, it's better to downscale 4K to HD 1080p with VideoProc Converter AI for it has a better compression method than TikTok.
