How to Calculate Video File Size

File size from bitrate and length

What equation our file size bitrate calculator uses

Despite the many variables in video quality settings such as codec, frame rate, and resolution, calculating video file size is straightforward. All you need is the bitrate and the duration of your video. Our file size calculator allows you to quickly determine the storage requirements for your videos, helping you plan your bandwidth usage more effectively.

Understanding Bitrate and Why It Matters

Bitrate refers to the amount of data transmitted per second in a video, typically measured in megabits per second (Mbps). Higher bitrates result in better image quality, but also larger file sizes. By adjusting the bitrate in our calculator, you can easily estimate file sizes and make informed decisions about video quality and storage needs.

The Simple Formula for Video File Size

The formula for calculating video file size is: Video File Size = (Bitrate / 8) × Duration. This formula assumes that the bitrate is measured in megabits per second, and the duration is in seconds. The result is the file size in megabytes. This calculation helps simplify planning for both local storage and online streaming services.

Factors Affecting Video File Size

Although bitrate is the key factor in determining video file size, variables such as codec, frame rate, and resolution also play a role in video quality. By setting an appropriate bitrate in relation to the other factors, you can balance quality and file size to meet your specific requirements. Be sure to consider any audio you include, as it can also affect the total file size.

Why Use Our File Size Calculator?

Our file size calculator is designed to give you an accurate estimate based on your inputs. Whether you’re creating content for video streaming platforms or calculating the storage space for your personal library, our tool simplifies the process. By inputting your desired video length and bitrate, you can instantly see how much storage space you will need.

Planning Your Storage and Bandwidth

Knowing the video file size helps you plan storage capacity and bandwidth requirements. For example, if you're using a 64GB memory card and your 4K video has a bitrate of 280Mbps, you can calculate how many minutes of footage will fit. This knowledge is crucial for content creators, streamers, and businesses managing large-scale video libraries.
