How to use this calculator

Estimate total GIF runtime from the number of frames and delay per frame.

How the calculation works

  • Enter frame count.
  • Enter delay per frame in milliseconds.
  • The duration updates immediately.

Formula

Duration seconds = frames x frame delay milliseconds / 1000.

Example

80 frames with 50 ms delay runs for 4 seconds.

Understanding your result

Use the output as a practical starting point, then review it before using it in an important workflow.

Assumptions and limitations

  • Some GIFs use different delays for different frames; this calculator assumes one average delay.
  • Use Frame Rate Calculator when you know duration instead of delay.
