What is a Video File Size Calculator?
This Video File Size Calculator is designed to help you estimate the storage space required for your video files.
By inputting a few key parameters you can quickly determine the approximate compressed file size of your video. This information is crucial for planning storage requirements, managing upload times, and optimizing video production workflows.
Video File Size Formula
Our Video File Size Calculator uses a simple formula to estimate your video file size based on bitrate:
Compressed Video File Size (GB) = (Bitrate (Mbps) * Total Time (seconds)) / (8 * 1024)
Where:
Compressed Video File Size: The estimated size of the video file after compression (in gigabytes, GB)
Bitrate (Mbps): The amount of data processed per second. Higher bitrates usually mean higher quality but larger file sizes.
Total Time: The duration of the video in seconds
This formula provides a realistic estimate of the video file size after compression. It takes into account the desired bitrate, which is influenced by factors like resolution, quality settings, and the codec used.
How to Use This Calculator
Using our Video File Size Calculator is straightforward to use:
Enter the Pixel Length of your video (e.g., 1920 for Full HD).
Input the Pixel Width (e.g., 1080 for Full HD).
Specify the Frames Per Second (FPS) of your video.
Enter the Total Time of your video in minutes.
Choose the Bitrate range based on the desired quality and resolution.
The calculator will then provide you with an estimate of your compressed video file size in gigabytes.

What is Video Compression?
While our calculator provides file size estimates based on bitrate, it's important to note that most videos undergo compression before distribution. Video compression can significantly reduce file sizes without noticeably impacting quality. Common compression methods include:
H.264/AVC: Widely used for streaming and broadcasting.
H.265/HEVC: Offers improved compression over H.264.
VP9: Open-source codec used by YouTube and other platforms.
Compression can reduce file sizes by 50% or more, depending on the content and settings used.
FAQ
How do you calculate the file size of a video?
To calculate the file size of a video, our calculator considers these key factors:
Bitrate (Mbps): Determines how much data is processed per second.
Duration of the video (in seconds)
We use the following formula:
Compressed Video File Size (GB) = (Bitrate (Mbps) * Total Time (seconds)) / (8 * 1024)
This formula gives you an accurate estimate of the compressed video file size based on the bitrate and duration.
How big is a 1-hour 1080p video?
Let's calculate the size of a 1-hour 1080p video at a medium quality setting (5 Mbps bitrate):
Bitrate: 5 Mbps
Total Time: 3600 seconds (1 hour)
Compressed Video File Size = (5 * 3600) / (8 * 1024) = 2.20 GB
This is the compressed size at a medium bitrate. The size can vary depending on the bitrate and compression settings used.
How big is a 2-hour video file?
Let's calculate for a 2-hour 1080p video at a medium quality setting (5 Mbps bitrate):
Bitrate: 5 Mbps
Total Time: 7200 seconds (2 hours)
Compressed Video File Size = (5 * 3600) / (8 * 1024) = 2.20 GB
How many GB is a 2-minute video?
Let's calculate for a 2-minute 4K video at a high-quality setting (30 Mbps bitrate):
Bitrate: 30 Mbps
Total Time: 120 seconds (2 minutes)
Compressed Video File Size = (5 * 3600) / (8 * 1024) = 2.20 GB
This is the compressed size. With higher compression efficiency, the size could be reduced further depending on the codec used.
