Video Frame Size Calculator

How to Use This Calculator

1. Select a standard resolution from the dropdown, or choose "Custom" to enter specific dimensions.
2. If using custom, enter width and height in pixels.
3. Select the bit depth (24-bit RGB is standard for most video).
4. The calculator displays the uncompressed frame size, total pixels, and aspect ratio.

Frame Size Formula

Video frame size is calculated from resolution and bit depth:

Example: A 1920×1080 frame at 24-bit: Frame Size = (1920 × 1080 × 24) ÷ 8 = 6,220,800 bytes = 6.22 MB per frame. At 24fps, this equals 149 MB per second of uncompressed video.

Full Description

Understanding video frame size is important for planning storage, estimating memory requirements, and understanding uncompressed video data rates. Each frame in a video is essentially a still image, and the size of that image depends on its resolution (width × height) and bit depth (color information per pixel).

Uncompressed video files are enormous—a single minute of 1080p video at 24fps would be nearly 9 GB without compression. This is why video codecs (compression algorithms) are essential. However, understanding uncompressed frame size helps you understand the raw data rate, plan for video editing workflows that may use uncompressed or lightly compressed formats, and estimate storage needs for raw footage.

This calculator helps you determine frame size for different resolutions and bit depths. Use it to plan storage requirements, understand memory needs for video editing, and compare different resolution options. Remember that most video uses compression, so actual file sizes are much smaller than uncompressed frame sizes would suggest.
