How to change the aspect ratio of a video with Movavi Video Converter
Step 1. Install the Movavi video aspect ratio changer
Download the installation file for Movavi Video Converter and install the software on your computer. It will take just a few minutes.
Step 2. Add your video file
Click the Add Media button and select Add Video. In the dialog box, locate the folder with the file(s) you want to convert. Choose the necessary file(s) and click Open. You can also drag and drop files into Movavi Video Converter right from the folder they're stored in.
Step 3. Choose the output format
Open the Video tab to see the list of video formats, including MP4, AVI, WMV, and many others. To convert your video to a specific format, hit the name of the desired format. You’ll see a list of presets with different resolution options. If you want to keep the original resolution and aspect ratio, select the option with Original Size in its name. Want to change the aspect ratio of your video? For your convenience, we matched the most popular presets with corresponding aspect ratio values.
- 3:2: 480 × 320; 720 × 480
- 4:3: 240 × 180; 320 × 240; 640 × 480; 384 × 288
- 16:9: 640 × 360; 960 × 540; 1280 × 720; 1920 × 1080
- 16:10: 1280 × 800
Also, Movavi Video Converter includes dozens of ready-made presets for various devices, including iPod, iPhone, iPad, PSP, Xbox One, and many others. Just click Devices and find your device in the list. If you choose a ready-made preset, you don’t have to specify any additional options, because your video will be converted with the optimal settings for playing on the selected device. In this case, you can skip the next step and jump to Step 5.
Step 4. Specify video settings (Optional)
If you want to set the width and height for your video manually, click the Cogwheel button next to the Output format field. In the format settings window that appears, choose the appropriate video and audio codecs and specify various video parameters.
As Movavi Video Converter uses square pixels only during the conversion (except when converting to DVD), the aspect ratio of an output video is always set automatically according to its width and height proportions. So, open the Frame size list and select the right resolution option or pick Custom and enter the required width and height values into the corresponding fields. And don't forget to select the appropriate resize method!
After all the parameters have been set, hit OK, and you’ll be returned to the main program window, where you can finish transforming your video.
A note on saving video in a DVD-compatible format (VOB): all VOB files made in Movavi Video Converter contain non-square pixels so, after choosing the appropriate size preset, you can select the required aspect ratio – 16:9 (widescreen) or 4:3 (full screen) – in the format settings dialog.
Step 5. Launch video conversion
Now you need to choose the folder where the converted files will be saved. If you want to change the default “Movavi Library” folder, click Save to and specify a new folder in the dialog box that opens.
Click the Convert button to initiate the conversion process. The folder with the finished files will open automatically upon completion, unless you disabled the feature in the program settings.

Frequently asked questions
▶️ What is the widescreen aspect ratio?
Although widescreen is a relative term, the international standard for the widescreen aspect ratio is 16:9.
▶️ How to change the aspect ratio on Windows 10?
The aspect ratio on a Windows 10 PC isn’t permanently fixed. Like Windows 8 and other previous versions, Windows 10 has a minimal range of aspect ratios you can select within the operating system that are all tied to the resolution capabilities of your graphics card.
To change the aspect ratio, you’ll need to change the resolution using the following steps:
Right-click on your desktop and select Display Settings from the dropdown menu.
Scroll down until you see Display Resolution and click the dropdown menu.
Click to select any of the preset display resolutions that come in a range of aspect ratios and keep your screen on one that works with your monitor size.
▶️ How do I find the aspect ratio of a video?
Here are some processes you can use to find the aspect ratio of a video in Windows, or on a Mac, Android phone, iPhone, or iPad.
Right-click on a video file and select Properties from the menu. Then, click the Details tab at the top. Under the section labeled Video there are two labels for Frame Width and Frame Height.
With the width and height of the frame, it’s possible to calculate the aspect ratio using one of the free online calculators listed in the next FAQ question.
Use Finder on your Mac to locate the video file and open it in Apple QuickTime. Once the video is open, click Window and then Show Movie Info. Look for the label Current Size and that will tell you the dimensions of the video – width and height.
You can then use a pixel calculator listed in the FAQ question below to input the data and get your aspect ratio.
Open the Photos app on your Android phone and tap to open the video. Tap the video once to display the menu and then tap the Menu icon on the top right – the three dots – to open the file details. Scroll down to the section labeled Details and below the file name the dimensions should be displayed in the middle.
Again, the height and width are what show. You can use an aspect ratio calculator listed in the next question.
iPhone or iPad
Note that on an iPhone or iPad, a video file must be saved to the Files app in order to see the details of the file. So if the file isn’t saved and is located in the Photos app, you’ll need to hit the Share icon and save it to the device first.
Once it’s saved, locate the file within the Files app and tap and hold on the video until a menu appears. Select Info from the menu and you’ll be able to see the height and width dimensions of the video file.
Then, use an aspect ratio calculator listed in the next question.
▶️ How do I calculate the aspect ratio?
Doing all the math to calculate conversions of the width and height of a video into the aspect ratio isn’t necessary. There are plenty of free video aspect ratio calculators online to help you out. Here are a couple to use:
▶️ How do I calculate my aspect ratio in inches?
Again, you don’t need to do the math to convert aspect ratios to inches. There are plenty of online resources to help you out, but you may need to type in the height and width separately. Here are a couple:
▶️ What is the aspect ratio of a YouTube video?
All YouTube videos display in a 16:9 aspect ratio.
▶️ What aspect ratio is an Instagram video?
It’s according to where you’re viewing the video. Feed videos can play in 16:9, 4:5, and 1:1, but Instagram recommends 4:5 for videos.
Stories, reels, and Instagram live videos all play in a 9:16 vertical ratio.
IGTV videos preview in the feed format for 15 seconds and then the viewer can tap to view in 16:9 horizontal or 9:16 vertical on a phone.
Carousel videos also play in the same aspect ratios as the feed, but the first video is what will play for all videos. Instagram recommends 1:1 for this type of video.
▶️ What is the best aspect ratio for a Facebook video?
Facebook recommends a 4:5 aspect ratio for videos you think will be viewed on mobile only and 1:1 for desktop-oriented videos.
▶️ How do I handle stretched videos and remove black bars from videos?
Both problems usually happen when a widescreen video (16:9) is converted to 4:3 or vice versa.
To fix a 16:9 video converted to 4:3 you need to calculate the correct height. Since the converted video is supposed to be 16:9, i.e. W:H = 16:9, the height should be calculated as H = 9 × W : 16.
To fix a 16:9 video converted to 4:3 you need to calculate the correct width. The converted video is supposed to be 4:3, i.e. W:H = 4:3, so the width should be calculated as W = 4 × H : 3.
After making all the necessary calculations, you can use Movavi Video Converter to fix the video.
Add your video to Movavi Video Converter and select the appropriate output preset in the Video tab.
Click the Cogwheel button next to the Output format field.
Open the Frame size list and select the resolution that you've calculated above. If you want to set it manually, pick the Custom item and enter your width and height values into the corresponding fields.
Open the Resize method list and select Stretch if you want to correct stretched video or Crop if you want to remove black bars from the edges of your video.
Click OK then click the Convert button.
