Work out golden ratio typography instantly with clear inputs, formula shown and shareable results.
Each heading level multiplies the previous size by the golden ratio of 1.618, and the same ratio applied to the body size gives a natural line height. A single consistent ratio is what makes a type scale feel deliberate; the golden ratio is one common choice but 1.25 or 1.333 give tighter, more usable scales.
Type scale
size at level k = body size x 1.618 ^ k
size at level k = body size x 1.618 ^ k. Each heading level multiplies the previous size by the golden ratio of 1.618, and the same ratio applied to the body size gives a natural line height.
