Intelligent Optimization Tool for Video Aspect Ratio
Last updated, May 2023

On TikTok Ads Manager, different placements can have different aspect ratio requirements. This can be a big challenge when you have a video that you are ready to use in an ad, but can't. Before you throw out your video and go back to the drawing board, learn more about how this tool may be able to save the day.


The Intelligent Optimization Tool helps you change an unqualified video's aspect ratio into one that works with TikTok ads. While your video will be optimized to meet the video aspect ratio requirement, the other elements of your video will not be changed.


Optimizing Your Video Aspect Ratio with Proximity Rule

Based on the ads placement you select, your video will be optimized as follows:

  • ​News Feed App Series placements - your video will be optimized to 1:1 or 16:9

  • ​TikTok placements, your video will be optimized to 9:16, 1:1, or 16:9


Calculating your video's new aspect ratio

The image below shows how the aspect ratio optimization is calculated. The numbers on the axis are equal with the aspect ratios above it.


To find out where your video falls, follow these steps:


  1. ​Take your video aspect ratio (for example 9:16, 1:1, 16:9) and see where it falls on the line by comparing it to the picture by dividing your aspect ratio. For example, for 16:9 ratio, 16/9=1.7778.

  2. ​Take that number, and refer to cutoff segments:

  • ​If the number is between 0.3437 -0.7813, your vide will be optimized to a 9:16 video

  • ​If the number is between 0.7813 -1.3889, your video will be optimized to a 1:1 video

  • ​If the number is between 1.3889-3.5556, your video will be optimized to a 16:9 video
