Calculateur de Font Scale
Generate a modular type scale from a base size and ratio.
Formula and method
This calculator computes Step -1, Step 1, Step 2, Step 3 directly in your browser without sending data to an external server.
Mathematical formula
- Step -1:
base ÷ ratio - Step 1:
base × ratio - Step 2:
base × ratio × ratio - Step 3:
base × ratio³
Variables and parameters
- Base size (base): default value 16 px.
- Scale ratio (ratio): default value 1.25 x.
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.
