Screen-optimized variable sans with optical sizing and comprehensive language support
Why it matches: Inter provides WTF Forma's functional clarity in a screen-first package. Both typefaces prioritize reading efficiency and clean corporate tone. Inter's taller x-height and more open proportions give it slightly better screen legibility at small sizes, while Forma's DIN-influenced metrics provide better space efficiency. Inter's optical sizing axis compensates for the lack of dedicated width variants.
