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.
