Transitional Sans Serif typefaces
are characterized by upright verticality and horizontal stress that is similar to Transitional Serif letterforms. However, they differ in that Transitional San Serif typefaces do not have serifs.

These typefaces also have uniform stroke widths and are sometimes referred to as "anonymous sans serif" due to their plain appearance.

Transitional Sans Serif typefaces first made their appearance in the 20^th century.

A widely known typeface is Helvetica, created in 1957 by Swiss typographer Max Miedinger with Eduard Hoffman. It is also perhaps the most widely used sans-serif.
