Simplified ratio
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Scenario comparison

Formula
Reduce W:H by dividing both dimensions by gcd(W,H). For a new width w, the proportional height is h = wH/W. gcd is the greatest common divisor.
Simplify integer dimensions and scale to a new width.

- Simplified ratio
- 16:9
- Target height
- 720
Scope and limitations
Planning estimate using your entered parameters. No external service, device, live tariff or network is contacted.
Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.
Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
