Divide anything by the golden ratio
The golden ratio, roughly 1.618, is a proportion designers reach for because it feels naturally balanced. This calculator applies it to any value: it gives the larger and smaller partners and the two parts a length splits into at the golden point.
Starting from 100, the larger golden partner is about 161.8 and the smaller about 61.8, while a length of 100 divides into 61.8 and 38.2. Those numbers make quick work of type scales and layout grids.
