YouTube is the king of online video platforms. So how to get more followers and maximize your opportunity on YouTube? First and foremost, you need to use the right YouTube video size to give your viewers the best viewing experience.

So, in this blog, we will walk you through what exactly the right YouTube video size includes, and how to change the dimension, YouTube video’s aspect ratio, resolution, and YouTube image size to get your perfect YouTube video size!

Here is what you will learn:

YouTube Video Size: Right Resolution

When you decide to run your YouTube channel, uploading high-resolution video content is essential to offering the best viewing experience for viewers. Since the default YouTube aspect ratio is 16:9, the following 7 resolutions are recommended by YouTube for encoding videos.

YouTube video resolution from 240P to 2160P (4k)

YouTube video resolution from 240P to 2160P (4k)

To most YouTubers, the best resolution for YouTube video size is 1920x1080P, which is the full HD video and the most popular video quality playing on YouTube.

Why 1080P is the Best Resolution for YouTube Videos?

Nowadays, many mirrorless cameras or smartphones can shoot 4k videos (3840x2160p), which is twice the resolution as Full HD videos (1920x1080P). But why does shooting 1080P videos remain the best choice for most YouTubers? Here are our reasons:

1080P(Full HD) vs 2160P (4K) video

1080P(Full HD) vs 2160P (4K) video

  • Smaller video file size and more economical. Shoot a 1080P/24FPS video for 20 secs and you get a file of 117.4MB while a 2160p(4k)/24FPS video for 20 secs can produce a file of 260MB. That means shooting 1080P videos saves you from spending more on an extra hard drive and faster SD cards and better gears to shoot and edit a 4K video on PC.
  • Bandwidth and device compatibility. Smartphone and tablet users account for a large number of YouTube viewers. And most of the smartphones and tablets don’t have a 4K display. So, though your YouTube videos offer 4K resolution, in reality, most people can only watch your YouTube videos on 1080P or due to the narrow bandwidth and smoother viewing experience.

    YouTube Video Size: Right Aspect Ratio

    Unlike the video resolution, which is the total number of pixels in an image of a video, aspect ratio refers to the relationship between a video’s width and its height.

    The different aspect ratios of a video

    The different aspect ratios of a video

  • 16:9 aspect ratio. This is the default and best aspect ratio for YouTube video size. It’s also known as standard widescreen, landscape, or horizontal video.
  • 9:16 aspect ratio. This is vertical or portraits view, perfect for YouTube shorts, Instagram videos, TikTok, Facebook videos, etc.
  • 1:1 aspect ratio. This is a perfect square video for Instagram, Facebook, Twitter videos.
  • 4:3 aspect ratio. This is an old aspect ratio of TV and films used in the ’80s and ’90s. This aspect ratio adds a kind of old vintage style to your video.
  • 21:9 aspect ratio. This is the ultra-widescreen aspect ratio for movies. If you want to make a cinematic video, you may consider using this 21:9 video aspect ratio.
  • For YouTube, the right aspect ratio is 16:9, even on Mobile devices. It defaults to play in 16:9 on your PC. If you upload videos with a 9:16 or 4:3 aspect ratio to YouTube, YouTube will add padding or black/white bars on both sides to make it a 16:9 aspect ratio.
