YouTube is a large and globally recognized search platform and network. Individuals and businesses alike benefit from the platform by sharing video content, searching for educational information, and promoting products or personal skills and knowledge.

Regardless of the goals you set for your work on YouTube, it is of the utmost importance that you pay close attention to the characteristics of your online video content. With the correct YouTube video size, you will ensure your content is displayed properly, and in turn, achieve better audience reach, potentially increasing your profit.

In this article, you will learn the up-to-date video requirements, such as YouTube video resolution, aspect ratios, dimensions, and frame rates. All these video size peculiarities will help you create the best video for YouTube.

The Correct YouTube Video Size

A significant aspect of creating and uploading a video file concerns YouTube video dimensions and resolutions.

Any of the dimensions listed below will provide you with the proper video format. Whether a viewer uses a mobile device or a computer to watch the file can influence the user experience.

Resolution Name Quality
3840 x 2160 2160p 4K
2560 x 1440 1440p 2K
1920 x 1080 1080p Full HD maximum resolution
1280 x 720 720p HD minimum resolution
854 x 480 480p Standard definition
640 x 360 360p Normal website resolution
426 x 240 240p YouTube minimum video size

The guidelines are pretty straightforward. You can achieve the highest 4K video quality if you use the highest video resolution, 2160p, when recording it. However, aside from outstanding video quality, it will take a large amount of your mobile phone’s storage space. Later, when you are uploading your YouTube video, it will consume a lot of data and require a reliable internet connection due to the file size.

On the other hand, low video quality can be displayed differently on various devices, for instance, 240p or 360p. It works perfectly for older mobile devices, but such a video format delivers very poor quality on big screens, leading to a disappointing viewing experience.

The best option for a YouTube video is to use 1080p resolution. Your content will retain a professional look with top-notch quality, while you will save on the amount of your device’s storage space and data. Besides, Full HD resolution is considered to be the gold standard of video quality. It serves as the perfect combination of the best video size for YouTube and viewers’ satisfaction regardless of the video player.

Furthermore, to ensure that your result is almost perfect, you can also stick to the 720p resolution. The video will also be great for displaying on a variety of devices, including LCDs.

Here are a few more tips on the proper YouTube video dimensions that you need to know before you proceed with video recording:

  • 128 GB is the maximum file size for YouTube.
  • 12 hours is the maximum video length.
  • The accepted video formats are: .mov, .mpeg, .avi, .wmv, .mpegps, .flv, .webM, .3GPP.

If you are still getting acquainted with YouTube and trying to figure out how you can improve your channel, then using the suggested resolutions and dimensions will help you obtain great results.

YouTube Video Aspect Ratio

One more essential peculiarity to pay attention to when looking for the perfect YouTube video format size is the aspect ratio.

The aspect ratio of a video defines its proportion on the screen and ensures its professional look on YouTube. It relies on the ratio of the video, based on its width and height.

There are three default aspect ratios:

1:1 aspect ratio: The main feature of this ratio is the equality of the video’s length and width. This “square” type of aspect ratio is widely used in videos for social media, for instance, Instagram.

4:3 aspect ratio: This is another aspect ratio, characterized by an increase in width compared to the previous one. Videos in this ratio provide an image that is 4-inches wide and 3-inches long. In the early days of television, this aspect ratio was considered to be the video standard.

16:9 aspect ratio: It is the most common type of aspect ratio. It is based on a 16-inch width and a 9-inch length. This file format is also known as widescreen. Nowadays, it serves as the standard and ensures the best viewing experience.

For your convenience, here is an image of how the video looks in different aspect ratios.

The 16:9 aspect ratio is the best one to use for any other professional video content. And in regards to YouTube, this ratio is also the most common one.

Whenever you upload a 4:3 or a 1:1 video onto the YouTube platform, the system will render the video display amendments and add black bars around the image to fill in the empty spaces on both sides of the video. This will make the video look amateurish and unattractive to viewers.

That is why it is always better to use the 16:9 aspect ratio to develop the best YouTube video file size.

YouTube Frame Rate

A frame rate is another feature worthy of your attention if you post video content to YouTube. The YouTube video must be uploaded and encoded in the same frame rate in which it was recorded.

When we speak about the most common frame rates, 24, 25, 30, 48, 50, and 60 frames per second are widely used in videos. However, other frame rates are not forbidden.

Importantly, before you post content, remember to deinterlace it. Suppose you have a 1080i60 video that needs to be deinterlaced to 1080p30. That means that 60 interlaced fields per second must be transferred to 30 progressive frames per second.

YouTube Video Guidelines

Here is a brief list of the most significant guidelines defining the size of a video on YouTube in proportion, resolution, and aspect ratio.

  • 128 GB is the maximum file size.
  • 12 hours is the maximum video length.
  • 2160p is the maximum video resolution.
  • 240p is the minimum video resolution.
  • 16:9 is the best aspect ratio.
  • The supported video formats are: .mov, .mpeg, .avi, .wmv, .mpegps, .flv, .webM, .3GPP.

In a situation when the video that you want to upload on YouTube does not correspond to the necessary formats, you do not need to give up and start over again. Use a special video converter to change the size settings into the correct ones. It is a quick and simple process that will improve your video and prepare it for upload.

There is also another option to adjust the video format. You can edit the video you created and select the right format.

Besides, if your video overshoots the maximum length limits (12 hours) or size (128 GB), compress the file before uploading it.

It is also important to mention that you can only upload videos of up to 15 minutes onto YouTube by default. To expand your options, you will need to verify your account.
