Video Resolution Calculator

Solve a missing video dimension from a width, height and target aspect ratio.

Aspect ratio width

Aspect ratio height

Known width (px)

Height is rounded to the nearest practical even pixel count because many 4:2:0 encoders expect even dimensions.

How to use this calculator

What to enter

Enter or select the following as requested: Aspect ratio width; Aspect ratio height; Known width (px). Follow the units, valid ranges, examples, and options displayed beside each field.

What the result means

The output gives the imaging, print, video, or audio value implied by the settings entered. Confirm whether the tool uses pixels, physical dimensions, frames per second, samples, bits, or another unit, and check the intended output medium.

When to use it

Use this to plan capture, editing, playback, or print settings. Preview the result on the target device or medium because display, compression, and hardware behavior can affect the final outcome.
