LTR Principia is a delightful new variable typeface with seven carefully picked widths. The most condensed version takes up about half the space of the widest, which means you can have a lot of fun fitting words into tight corners or stretching them to fill a void. Principia is excellent for headlines, titles, spines, logos, posters, exhibitions, banners, billboards and sides of buildings. With its wasp-waisted contrast and distinctive ball terminals, it’s a stand-out in all sizes.
