When it comes to uploading videos to YouTube, one of the most common questions creators have is: how much storage space will my video take up? The answer, however, is not as straightforward as it may seem. The file size of a YouTube video can vary greatly depending on a multitude of factors, including resolution, frame rate, bitrate, and more.
Understanding Video File Sizes
Before we dive into the specifics of YouTube video file sizes, it’s essential to understand the basics of video file compression and encoding. Video files are made up of a series of compressed images, known as frames, which are combined with audio data to create the final video. The quality of these frames, as well as the audio data, have a direct impact on the overall file size of the video.
Resolution and Aspect Ratio
The resolution of a video refers to the number of pixels that make up each frame. A higher resolution means more pixels, which results in a larger file size. The most common resolutions used on YouTube are:
- 360p (640×360 pixels)
- 480p (854×480 pixels)
- 720p (1280×720 pixels)
- 1080p (1920×1080 pixels)
- 1440p (2560×1440 pixels)
- 2160p (3840×2160 pixels)
Aspect ratio, on the other hand, refers to the proportional relationship between the width and height of the video. The most common aspect ratios used on YouTube are 16:9 (widescreen) and 4:3 (standard).
Bitrate And Encoding
Bitrate refers to the amount of data used to encode each second of video. A higher bitrate results in a larger file size, but also improves video quality. The bitrate of a video is usually measured in kilobits per second (kbps) or megabits per second (Mbps).
Encoding, also known as transcoding, is the process of converting a video file from one format to another. YouTube uses the H.264 encoding standard, which is a high-efficiency format that balances file size with video quality.
Codecs and Containers
Codecs (compressor-decompressor) are algorithms used to compress and decompress video and audio data. The most common codecs used on YouTube are H.264 for video and AAC (Advanced Audio Coding) for audio.
Containers, on the other hand, refer to the file format that holds the compressed video and audio data. The most common container formats used on YouTube are MP4, WebM, and FLV.
YouTube’s File Size Limits
YouTube has file size limits in place to ensure that users can upload and play back videos efficiently. The current file size limits are:
- Up to 128 GB for verified accounts
- Up to 20 GB for unverified accounts
However, these limits are subject to change, and YouTube may reject videos that exceed these limits or take too long to upload.
Estimating YouTube Video File Sizes
So, how many GB is a YouTube video? The answer depends on a variety of factors, including resolution, frame rate, bitrate, and more. Here are some estimated file sizes for different types of videos:
- 360p (640×360 pixels), 30fps, 1 Mbps: 100-200 MB per minute
- 480p (854×480 pixels), 30fps, 2 Mbps: 200-400 MB per minute
- 720p (1280×720 pixels), 30fps, 5 Mbps: 500-1000 MB per minute
- 1080p (1920×1080 pixels), 30fps, 10 Mbps: 1-2 GB per minute
- 1440p (2560×1440 pixels), 30fps, 20 Mbps: 2-4 GB per minute
- 2160p (3840×2160 pixels), 30fps, 50 Mbps: 5-10 GB per minute
As you can see, the file size of a YouTube video can add up quickly, especially for higher resolutions and frame rates.
Optimizing Video File Sizes
So, how can you optimize your video file sizes for YouTube? Here are some tips:
- Use a lower resolution: If you’re not planning to upload a 4K or 8K video, consider using a lower resolution to reduce file size.
- Reduce the bitrate: Lowering the bitrate can significantly reduce the file size, but be careful not to compromise video quality.
- Use a more efficient codec: H.265, also known as HEVC (High Efficiency Video Coding), is a more efficient codec than H.264, but may not be compatible with all devices.
- Use a container with better compression: WebM is a container format that offers better compression than MP4, but may not be compatible with all devices.
- Split long videos into multiple parts: If you have a long video, consider splitting it into multiple parts to reduce file size and make it easier to upload.

How Do I Determine The File Size Of A YouTube Video?
To determine the file size of a YouTube video, you can use various online tools or check the video’s settings. One way is to use online tools like SmallPDF or Meta Analyzer, which can scan the video’s URL and provide you with the file size and other details. Alternatively, you can check the video’s settings on YouTube itself. To do this, click on the three dots below the video title, select “Stats,” and then click on “More” to find the video’s file size.
Keep in mind that the file size may vary depending on the video quality and format. For instance, a 4K video will have a larger file size than a 1080p video. Additionally, the file size may also depend on the video’s length, bitrate, and other factors. So, it’s essential to consider these factors when determining the file size of a YouTube video.
What Is The Average File Size Of A YouTube Video?
The average file size of a YouTube video can vary greatly, depending on several factors such as video quality, length, and format. However, on average, a 1080p video can range from 1 GB to 5 GB per minute, while a 4K video can range from 5 GB to 20 GB per minute. This means that a 10-minute 1080p video can have a file size of around 10 GB to 50 GB, while a 10-minute 4K video can have a file size of around 50 GB to 200 GB.
It’s worth noting that YouTube has a file size limit of 128 GB for uploads, although most videos are significantly smaller than this. Additionally, YouTube also has a recommended upload encoding setting, which can help reduce the file size while maintaining video quality. This setting recommends a bitrate of 5,000 to 10,000 kbps for 1080p videos and 20,000 to 50,000 kbps for 4K videos.
How Does Video Quality Affect File Size?
Video quality has a significant impact on file size. A higher video quality means a higher resolution, bitrate, and frame rate, which results in a larger file size. For instance, a 4K video has a much higher resolution than a 1080p video, which means it requires more data to store and process, resulting in a larger file size. Similarly, a video with a higher frame rate, such as 60fps, will have a larger file size than a video with a lower frame rate, such as 30fps.
The bitrate also plays a crucial role in determining file size. A higher bitrate means more data is being processed per second, resulting in a larger file size. However, a higher bitrate also means a higher video quality. So, it’s essential to strike a balance between video quality and file size when uploading videos to YouTube.
What Is The Maximum File Size For YouTube Uploads?
The maximum file size for YouTube uploads is 128 GB. However, this limit only applies to verified accounts. For unverified accounts, the maximum file size is 12 hours and 12 GB. YouTube also has a recommendation for upload encoding setting, which recommends a file size of around 1 GB to 5 GB per minute, depending on the video quality and resolution.
It’s worth noting that even if your file size is within the limit, YouTube may still reject your upload if it exceeds the recommended encoding setting. Additionally, larger file sizes can take longer to upload and process, which may affect your video’s availability on YouTube.
Can I Reduce The File Size Of A YouTube Video?
Yes, you can reduce the file size of a YouTube video without sacrificing video quality. One way to do this is by compressing the video using video compression software or online tools.

Another way is to use a lower video quality setting when uploading the video to YouTube.
Additionally, you can also use YouTube’s built-in compression feature, which can reduce the file size while maintaining video quality. This feature is available in the YouTube Studio dashboard, where you can select the compression quality and file size before uploading the video. By reducing the file size, you can save storage space and bandwidth, making it easier to upload and share your videos on YouTube.
How Does Video Length Affect File Size?
Video length has a direct impact on file size. The longer the video, the larger the file size. This is because longer videos require more data to store and process, resulting in a larger file size. For instance, a 10-minute video will have a larger file size than a 5-minute video, assuming the same video quality and resolution.
The video length also affects the file size when combined with other factors such as video quality and resolution. For example, a 10-minute 4K video will have a much larger file size than a 5-minute 1080p video. So, it’s essential to consider the video length when determining the file size and adjusting the video quality and resolution accordingly.
Can I Estimate The File Size Of A YouTube Video Before Uploading?
Yes, you can estimate the file size of a YouTube video before uploading. One way to do this is by using online tools or video compression software that can provide an estimated file size based on the video’s settings and quality. Another way is to use YouTube’s built-in file size estimator, which can give you an estimated file size based on the video’s duration, resolution, and quality.
Additionally, you can also use the following formula to estimate the file size: File size (GB) = (Video duration (minutes) x Video resolution (pixels) x Frame rate (fps) x Bitrate (kbps)) / 8. This formula provides a rough estimate of the file size, which can help you plan your video uploads and adjust the video quality and resolution accordingly.
