TikTok Video Dimensions – Screen Size & Aspect Ratio Guide

TikTok is a video creation platform, which let’s users record their own videos and share them online.

TikTok videos have their restrictions and recommended dimensions, and sticking to these recommendations will make sure your video shows up well on a normal smartphone screen.

Making sure you use the right TikTok video size is essential. In this article, we’ll go over some of these details.

TikTok Video Dimensions

We’ll firstly go over the dimensions of TikTok videos, as well as their aspect ratios, orientations, and supported file types.

The basic dimension of a TikTok video is 1080×1920. The aspect ratio should be 9:16 or 1:1. This is similar to the size of a phone screen. The default orientation of a TikTok video is vertical, and in most cases you’ll want to create a vertical video.

But, you can change it to horizontal if you so wish – you can switch to making a landscape video if you so wish.

When making Duets, you can also change the layout type. The default is a side-by-side split screen, but you can change the position of the split screen if you want.


TikTok supports multiple file types, including .mp4 and .mov. The average size of a TikTok video, when downloaded, is around 280 MB on iOS or 70 MB on Android.

TikTok Video Lengths

The default TikTok video length limit is 15 seconds. Every TikTok must be a minimum of 3 seconds long. You can change the video length limit when you record a TikTok.


Above the record button, there should be three time options. These are the different video length limits. You can choose 15 seconds, 60 seconds, or 3 minutes.

When you upload a TikTok video from your gallery, the video length limit does not apply. There are a few tricks you can use you make longer TikTok videos, too.

How to Resize a TikTok Video

You can choose to resize a TikTok video using external video-editing sites. You must first download the TikTok in question.

Launch the TikTok app and locate the TikTok you wish to resize. If it’s one of your own TikToks, it should be located on your profile page. To access your profile, simply press the person icon in the bottom right.

Once you’ve found the TikTok, press on it and select the share icon. If the TikTok is private, select the three dots instead. A set of options should appear. Press the ‘save video’ option to download the TikTok.


After downloading the TikTok, you must navigate to a third-party video-editing site. There are many sites available, but we’ll focus on Clideo in this article.

Go to clideo.com and select the ‘resize’ option.


This should take you to the video resizer.


Click the ‘choose file’ option and select the TikTok you just installed. You can upload it from your files, or from a cloud source like Google Drive.

Once the video has been uploaded to the site, look for the ‘resize for’ section. Click on the drop-down menu beneath that section, and choose the ‘custom’ option. Then, set the aspect ratio to 9:16 or 1:1.


Next, if you want the video to fill up the screen, press the ‘fill’ option. If you don’t want the video to be cropped or zoomed in on, press the ‘fit’ option.

If you choose the latter, there may be a border around the video. You can change the colour of the border by clicking the paint bucket icon, and selecting a colour.

When you’re finished resizing the video, click the ‘export’ option process the video. When it’s done processing, click the ‘download’ option to save the video.

How to Upload a TikTok Video

After resizing or recording a video external from the TikTok app, you can upload it to TikTok.

Open the TikTok app and press the plus icon. Then, select the ‘upload’ option next to the record button.


This should open up your gallery. Choose the video you want to upload. Once it’s been uploaded to TikTok, you can use TikTok’s editing tools to edit the video.

You can enhance the video with text or filters, or trim the video by selecting ‘adjust clips’. You can even add sounds from TikTok to the video by pressing the ‘add sounds’ option.

When you’re done, press the ‘next’ option. Edit the video description and privacy options, and press the ‘post’ option when you’re ready.

Alternatively, you can record a video within TikTok, and upload a video that way. After pressing the plus icon in TikTok, press and hold the red button to start recording a video. Let go of the red button when you’re done recording.


You can edit the video using the tools on the right, or press the checkmark to move on. You can then further edit the video, and press ‘next’ to view the video details.

Or, you can select ‘post to story’ to post the TikTok to your story.

In the video details, you can add a description, add mentions, add hastags, and edit privacy settings.


When you’re ready to post the TikTok, press the ‘post’ option.


In conclusion, TikTok videos have their pre-set dimensions and ratios. These can’t be altered in the TikTok app. If you’re making a Duet, you can change the layout.

Otherwise, you’ll have to alter the ratios and orientations outside of the TikTok app. You can edit a video on your device or an external site, and upload the video to TikTok.
