CoreHumanistSans by Alex Scholing is a typeface reduced to the max: clean and simple but peaceful, unpretentious and pleasant. There is no contrast in the characters, which means that the strokes are equally thick everywhere, hence the ‘Core’ in the name.
The terminals of characters like a, c, e and s point in a horizontal rather than a vertical direction, which gives the typeface an open and accessible character, hence ‘Humanist’.
The ‘Sans’ part speaks for itself. Probably the best part, it’s totally free for download. Find it here.
