Since it is part of the Duplet superfamily, you can combine Duplet Rounded with its relatives: Duplet Open and Duplet. Each contains seven weights ranging from Thin through ExtraBold, all with companion italics. The fonts include more than 450 glyphs, covering all the European languages written with the Latin script.

Since the Duplet Rounded fonts are geometric, the round characters and round-parts of letters appear either as circles or slanted circular forms (like you see in the italics). Duplet Rounded’s letterforms are very low-contrast, with stroke that seem even in thickness.

The default form of the ‘a’ in each font is single-storey. The large round bowl drives Duplet Rounded’s inherent geometry home! But there is a double-storey ‘a’ as an OpenType alternate ‘a’. The default ‘g’ is also single-story, and its bottom stroke is flattened, giving it a streamlined, less-complicated look. Duplet Rounded’s fonts feature three more ‘g’ versions as alternate characters.

There are alternates for ‘k’, ‘u’, ‘G’, ‘K’, and ‘M’, as well as the ampersand (&). The character sets include case-sensitive forms, too — punctuation marks that are vertically repositioned and look better in all-caps texts. When it comes to numerals, both proportional and tabular lining figures are there, as well as fractions, superior numerals, and inferiors. Diana Ovezea and Rafał Buchner designed this typeface with great attention to detail.
