ABeeZee is a children's learning font. Open, friendly and simple, the definite shapes support the process of learning to read and write. The italic carefully reminds young readers of fluent writing movements and inspires them to create their own unique handwriting. Learn more at carrois.com.
Abel is a modern interpretation of the condensed flat-sided sans serif. Originally used for newspaper headlines and posters, this style can also be used for text on the web. Its angled terminals and spiked stems give it enough style to be unique at display sizes, while its mono-weight still works well at smaller text sizes. Documentation can be found at www.madtype.com and to contribute to the project contact Matthew Desmond at mattdesmond@gmail.com
Abril Fatface is part of a bigger type family system, Abril, which includes 18 styles for all Display and Text uses. The titling weights are a contemporary revamp of classic Didone styles, display both neutrality and strong presence on the page to attract reader attention with measured tension by its curves, good color and high contrast. Abril Fatface in particular is inspired by the heavy titling fonts used in advertising posters in 19th century Britain and France. The thin serifs and clean curves lend the typeface a refined touch that give any headline an elegant appearance. The Extended Latin character set supports over 50 languages, including those from Central and Northern Europe. Abril is designed by TypeTogether - Veronika Burian & José Scaglione. The additional weights of Abril can be seen at www.type-together.com/Abril
Aclonica is a strong and modern sans serif typeface with a slight deco/techno essence to it. Clean letterforms, a generous x-height for a friendlier feel and easily legible typestyle. Perfect for both display titling as well as body copy.
Acme is a condensed display typeface inspired by the visual language of classic cartoons and comics. It is designed to be used in headlines, and has a particular and groovy rhythm. The resulting texts are vivid but consistent, and its expressive characteristics work as well on screen as in print. The glyphs were each carefully designed, with top curve quality. It is well balanced, and carefully spaced by eye. Designed by Juan Pablo del Peral for Huerta Tipográfica.
A diploma thesis project from the Aachen University of Applied Sciences at Karl-Friedrich (Kai) Oetzbach. The font originated in a course in type design. The idea was to learn through the creation of a typeface about writing as an information carrier. It was created entirely digitally, so the path to the current version is very rocky and winding. Actor has a strong x-height, which is why it always requires a fairly high line spacing. The digits of Actor are created as old style figures. The forms of 6 and 9 are more dynamic and more tense than usual. The 8 has significantly shifted interiors and the 7 is slightly curved to the left.
Adamina is a typeface designed for text setting in small sizes. For this purpose the x-height is increased and contrast lowered. Proportions are transitional and compact. Refined design features like one-sided flaring and asymmetrical serifs are there to provide a pleasant reading experience. Designed by Alexei Vanyashin for Cyreal.
Advent Pro is a modern font designed for web and print. Advent Pro utilizes some of the universal characteristics of a sans-serif font with modern characteristics to give an edge to your typography. The font supports a wide range of languages including Greek, Turkish, English and German.
