Formula and method
This calculator computes Scaled width, Scaled height directly in your browser without sending data to an external server.
Mathematical formula
- Scaled width:
width × scale ÷ 100 - Scaled height:
height × scale ÷ 100
Variables and parameters
- Original width (width): default value 1920 px.
- Original height (height): default value 1080 px.
- Scale (scale): default value 150 %.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
Examples
- Example: with Original width = 1920 px, Original height = 1080 px, Scale = 150 %, this calculator returns Scaled width = 2880 px, Scaled height = 1620 px.
