Why These Tools
Typography Scale Generator exists because modular type scales are one of those concepts every designer knows and every developer recreates from scratch. Picking font sizes by hand produces a set of numbers that feel fine in isolation and fight each other in a layout; a fixed ratio applied at each step produces sizes that belong to the same geometric family. The generator makes that ratio a slider rather than a formula, so you can compare a Major Third against a Perfect Fourth in seconds rather than recalculating a spreadsheet.
CSS Spacing Scale Calculator, Grid System Calculator and CSS Unit Converter join from the CSS Generators hub because they all operate at the same level of abstraction: the structural layer of a stylesheet, above individual components but below visual styling. Keeping them together means a designer building a new design system can move from type scale to spacing scale to grid without switching hubs.
