Before we dive into the nitty-gritty of the do’s and don’ts of video sizes, let’s first talk about essential video-related terminology.

These words are peppered across the guide and even in most video-related guides you’ll read online.

If you’re reading video-related how-tos, you’re almost 100% guaranteed to run into these words.


The word “pixel” is an abbreviation of the phrase “picture element.” Pixels represent the tiniest element within a digital display. They’re super small squares or building blocks that, when put together, form the image shown on a screen, such as texts, graphics, or videos. Videos can have millions of pixels; the more pixels a video has, the higher its resolution.


Video resolution is the number of pixels contained in video frames. If a video has a resolution of 2560×1440 pixels, that means the video has a width of 2560 pixels and a height of 1440 pixels. The higher resolution a videos has, the smoother, more detailed, and more realistic its image quality will be.

Video frame

A video frame is a still image. When shown one after another in rapid sequence, the human mind views the quick change of frames as a continuous movement, allowing us to watch a video. A great example would be grabbing a notebook, drawing an image on the pages, and then flipping the pages quickly. When the pages are flipped rapidly, the images you drew on the pages appear like they’re moving. The individual pages, in this case, are the video frames.

Frame Per Second (FPS)

In the definition of the video frame above, we talked about the pages of the notebook being flipped quickly. The Frame Per Second (or FPS) is how quickly the pages are flipped.

Aspect ratio

Essentially, the aspect ratio is how a video fits on your device’s screen, whether a TV screen, smartphone, etc. The ratio is often expressed as “X:Y,” where X pertains to the video’s width, and Y is the length. An example aspect ratio would be 9:16. While the numbers are in reference to pixels, the figures themselves are only the ratio of the width and height of the video. After all, 9 px by 16 px would be too small.


The dimension of a video is expressed through its width and height.

The width and height of a video is often measured in pixels. If the video has a width of 640 pixels and a height of 360 pixels, the YouTube video dimensions would be 640 x 360 pixels.

YouTube algorithm

The YouTube algorithm is a recommendation system used by YouTube to determine which videos to show in front of its users. It primarily considers the video’s performance and the user’s watch history.


Bitrate is the amount of video data that is transferred during a specific amount of time. It mainly affects your video’s quality and size and is measured in bits or bits per second.

Video codec

Codecs are computer programs or devices that compress and decompress digital signals and data streams. In video, a codec encodes and decodes video files so viewers can save on internet bandwidth and keep watching high-quality videos.

Video matting

Video matting separates videos into multiple layers, typically the foreground and background, and generates an alpha matte.

The alpha matte determines the blending of the video layers.

Video matting is popular in video editing since it replaces the process layers or background separately.

What is the best YouTube video size?

A video’s aspect ratio determines its proportion on the screen and ensures it looks professional. It relies on the video’s ratio based on the height and width.

Below are aspect ratio examples:

  • 1:1 aspect ratio. This ratio’s main feature is the video’s width and length equality. The 1:1 square aspect ratio is commonly used in social media like Instagram in-feed videos. 
  • 4:3 aspect ratio. This ratio displays videos as four inches wide and three inches long.  
  • 16:9 aspect ratio. 16:9 is a common aspect ratio type (known as the widescreen format) is 16 inches wide and 9 inches long. It is the standard aspect ratio used to ensure the best viewing experience.  

YouTube’s aspect ratio defaults to 16:9.

These are video dimensions with an aspect ratio of 16:9.

  • ​​1920 x 1080 (Full HD or 1080p)
  • 1280 x 720 (HD or 720p)
  • 3840 x 2160 (4K Ultra HD)

If your video has a different aspect ratio, YouTube will change it to the ideal size to align with your video and the viewer’s device.

However, in some situations, YouTube will add padding to your video to give the users a better viewing experience.

4k Ultra HD gives your videos the highest resolution of 2160p when recording.

However, while this gives you excellent video quality, it can also take up a lot of phone storage space.

It can also consume a lot of data and require a reliable, strong internet connection when uploading because of the file size.

Lower-quality videos, such as 240p and 360p, display more easily across various devices, including older models.

The catch is that these formats show your videos in poor quality, especially on bigger screen displays, which can ruin the viewing experience.

Your best bet is to use the 1080 resolution since it is high quality enough without consuming too much storage or bandwidth when viewers play your videos.

The 1080 resolution is the video quality gold standard, providing the best video size and quality to viewers regardless of the device or screen size.

How to change the size of a YouTube video?

There’s a myriad of reasons why you need to learn how to change the size of a YouTube video.

For example, if you plan to publish your YouTube video on other social media platforms to get more mileage from each video content you create, you may need to resize it.

YouTube’s aspect ratio defaults to 16:9. But other platforms, such as TikTok, often prefer an aspect ratio of 9:16.

So before you publish your YouTube video on TikTok, it’s a great practice to resize it first so it fits perfectly to TikTok’s preferred 9:16 aspect ratio.

One of the easiest ways to change your YouTube video’s size is to use free online video editors.

Tools like Adobe Express let you resize your videos for YouTube for free.

Upload your video from your device (up to an hour long), enter a custom size, or select YouTube as your destination so the tool automatically adjusts your video to the platform’s default ratio.

Once resized, you can download your video within minutes.

Use similar tools with simple resizing features to get the right YouTube video size quickly.

Youtube video specs

YouTube recommends uploading your videos in the original and high-quality source format to ensure they play at their highest quality.

YouTube’s video formatting guidelines have specifications to ensure the highest quality for videos played on the platform, including the following.

File format

YouTube recommends using the original 1080p HD broadcast format, including the DVD-compliant MPEG-2 (or MPEG-4) program streams saved with a .MPEG extension.

These specifications give optimal playback:


  • Audio codec – Dolby AC-3 or MPEG Layer II 
  • Audio bitrate – 128 kbps and up

  • Video codec – H.264
  • Audio codec – AAC
  • Audio bitrate 128 kbps and up

Video resolution

YouTube recommends using high-definition videos, generally those with the highest resolution available, to give maximum flexibility for playback and encoding processes.

Videos for rent or sale should have an aspect ratio of 16:9 and a minimum resolution of 1920×1080.

YouTube doesn’t provide a minimum resolution for content with or without ads, but it recommends the following

  • Videos with a 16:9 aspect ratio should have a minimum resolution of 1280×720 
  • Videos with a 4:3 aspect ratio should have a minimum resolution of 640×480

Aspect ratio

Below are the recommended YouTube video aspect ratios:

  • A video with a native aspect ratio of 1.77:1 with a total frame size of 1.77:1 should have 16:9 matting without a border and with square pixels.
  • A video with a native aspect ratio of 1.77:1 with a total frame size that doesn’t have a 1.77:1 aspect ratio must use 16:9 matting with a single color border with no variations and with square pixels. 
  • A video with a native aspect ratio and total frame size of 1.33:1 must use a 4:3 matting with no border and with square pixels. 
  • A video with a native aspect ratio of 1.33:1 with a different frame size aspect ratio should use 4:3 matting with a single-color border with no variations and square pixels.  

Video bitrate

YouTube doesn’t recommend a minimum value for bitrate since it is highly dependent on code.

Optimize your videos for frame rate, resolution, and aspect ratio instead of bitrate.

Videos for rental or sale usually have bitrates of 50 or 80Mbps for top quality.


Generally, your YouTube videos must be in their native framerates (without resampling) and should be set at 24, 25, or 30 frames per second.

Avoid resampling techniques since these can lower your video’s quality and cause images to shudder.

Film sources should be set at 24fps or 25fps to get the best results.

Check YouTube’s audio file guidelines to ensure high-quality audio tracks for your videos.

What’s the best video format for YouTube

The best YouTube video format is the one that plays your videos at their highest quality.

Stick to YouTube’s recommended format and specs, including the following:

  • MP4 (.MP4) format for best high-quality video uploads. .MOV is the second best-recommended format. If your videos are in other formats, consider converting them to .MP4 or .MOV before uploading them to YouTube. 
  • 15 to 20 MBS

While there are other supported YouTube file formats, try sticking to the top two recommended video formats since others don’t always provide the same audio and quality levels as those two.

Crucial YouTube guidelines

There’s a lot to remember when enusring you follow the best and recommended YouTube video sizes, specs, formats, and more.

Here’s a quick summary of the most important YouTube video guidelines you should remember:

  • The maximum file size is 128 GB.
  • The max video length is 12 hours (720 minutes).
  • The maximum video resolution is 2160p with 1080p as the standard high-quality resolution, and the minimum video resolution is 240p.
  • The best aspect ratio is 16:9. 
  • The best video format is .mp4, followed by .mov, but YouTube also supports .avi, .mpeg, .flv, .mpegps, .3GPP, and .webM.  

Compress your video file if it exceeds the 128 GB size or 12-hour limit before you upload videos to YouTube.

You must also verify your YouTube brand account before uploading videos that exceed (default) 15 minutes.

Best practices for choosing a YouTube video size

Consider these tips to nail your YouTube video’s size.

  • YouTube supports multiple framerates, including 24, 30, and 60 frames per second, but it’s crucial to use one that doesn’t consume too much data while keeping your video’s quality decent. For instance, 60 fps results in a smoother motion, but it can take more data and isn’t necessary for all content types. 
  • Stick to the 16:9 aspect ratio for your YouTube videos since it is the most versatile and works well on various tablets, smartphones, and computers. 
  • Go for a resolution that matches your video’s quality and target audience’s commonly used devices. Your safest bet is to use 1080p to ensure better video quality across various devices. Also, consider using the same resolution for your videos for consistent quality. 
  • Use the recommended and widely used H.264 (MP4) format. It gives good quality and compression for your videos. It is compatible with many devices and platforms, which is handy if you’re posting your YouTube videos on another social media platform or your website.  
  • Opt for a bitrate that balances file size and quality without bypassing the YouTube guidelines. Higher bitrates can give your videos higher quality but also make your file sizes larger, so choose accordingly. 
  • Optimize your YouTube video size for mobile viewers. Use a video size and resolution that look great on smaller screen displays without compromising quality and clarity. 
  • Ensure your chosen video size doesn’t distort or cut off your YouTube video thumbnail image. Don’t place any important details or elements near the edges of your video’s frame so they don’t get cropped when viewed in smaller device displays. 
  • Focus on providing an excellent viewing experience to your target audiences. Select a size that keeps your videos high quality while catering to your viewers’ preferred devices. 
  • Encode your original video using AAc audio at 128kbps or higher for top-quality video audio. 
  • Consider keeping your YouTube video sizes consistent across your channel. It helps provide your audiences with a more cohesive viewing experience. 
  • Opt for a video size that complements your content’s lighting and background conditions. High resolution can highlight imperfections within low-quality lighting setups, so choose a video size accordingly. 
  • If your video has texts, subtitles, and captions, select a video size that ensures everything is readable and clear, especially on smaller screen displays. You can also use text that matches your chosen video size by applying the appropriate font sizes and styles. 
  • Test your video using various sizes, resolutions, and aspect ratios to see how they display on multiple devices. It helps you spot quality, size, or resolution issues in your videos that you can address and tweak before publishing. 
  • Track your YouTube video analytics to understand viewers’ behavior and preferences. Stay on top of key metrics such as audience retention, viewer engagement, and watch time to help you refine your YouTube video size choices and improve the viewing experience. 

Additional tip: Export your video in the highest quality settings your hardware can handle since this provides a good source file when you upload to YouTube.

Tune in to YouTube’s guidelines and documentation since they can change anytime.

Doing so helps you know the latest information on the platform’s recommended video settings and sizes and the best practices, allowing you to tweak your videos accordingly.
