Nov 09, 2021• Proven solutions
Before reading this article, you may ask:
What is the Aspect Ratio?
The term Aspect Ratio refers to the relationship between the width and height of a video, which is expressed normally in the form of "width: height", for example, 4:3 or 16:9, and it is irrelevant to the actual physical size of the image.
The most common video aspect ratios are 4:3 (1.3:1) and 16:9 (1.78:1). The former is the standard TV format, while the latter is the latest widescreen TV format. Besides these two, 1:1 and 9:16 are getting popular on social media sharing nowadays.
As far as you may know, many media players enable you to change the aspect ratio in real-time when playback. Yet the change is temporary. Next time you open it, you need to change the aspect ratio again. Besides, you may also need to convert a portrait video to landscape or convert the default 16:9 YouTube videos to sharing on IGTV (9:16) or other platforms.
Changing the aspect ratio of videos will provide you with plenty of options and in this article, we will share with you how to change the aspect ratio between 4:3, 16:9, 1:1, and 9:16.

Part 1: Choose the Right Video Editor
To change the aspect ratio permanently, you need a video editor or converter. Here I humbly recommend a remarkable aspect ratio changer - Wondershare Filmora video editor, which lets you create both 4:3, 16:9, 9:16, and 1:1 aspect ratio videos easily. You can share the created videos on Apple TV, YouTube, Vimeo, and mobile devices conveniently.
The video tutorial below shows how to fix the black bars in the YouTube video by changing the aspect ratio. Try Filmora Now!
Note: Since this video is made with the previous Filmora version, I've updated the latest steps of the changing aspect ratio in Filmora below.
Part 2: How to Change Aspect Ratio in Filmora
Method 1: Change aspect ratio at the Starting interface
The Filmora allows you to change the project aspect ratio after launching the video editor program. Click the drop-down menu and you will see the commonly used 16:9, 1:1, 9:16, 4:3, and 21:9 aspect ratios.
Method 2: Change Aspect Ratio under Project Settings
If you like, you could choose a target aspect ratio at the beginning after entering the main editing interface by clicking the Project Settings. It depends on the aspect ratio of your media source.
If most of your media source files are in the 4:3 aspect ratio, you should select the 4:3 standard aspect ratio. For you've selected an aspect ratio, then the media files that are in 16:9 or other aspect ratios will be converted with a black bar, and be stretched if necessary. This is the solution when aspect ratio discordance occurs. But if you just want to change the aspect ratio of one video file, simply choose an aspect ratio and go.
If you want to change the aspect ratio later, just select Project Settings to change it again.
Method 3: Change Aspect Ratio during Editing
After importing video files into the Filmora timeline, you can still change the aspect ratio at the Crop and Zoom tool.
Right-click on the clip in the timeline to select Crop and Zoom. Then a pop-up window will appear. By clicking manually, 16:9, 4:3, 1:1, and 9:16 at the bottom, you can change the aspect ratio with these presets or click Custom to enter the aspect ratio manually. After selecting, click OK. Then you will find aspect ratio will change.
If you find a black bar after changing the aspect ratio, you can add some background blur effects to enhance the video. Optionally, you can edit and enhance your video with plenty of filters, overlays, visual effects, titles.
