OT Carta Straight Mono

OT Carta is a type family designed and adapted for people with dyslexia and other reading difficulties. Primarily intended for older readers who are already accustomed to reading sans serif letters (Helvetica, Arial, etc.). Fonts are compatible with Omoguru tools that help with reading, and allow each user to customize the options to their preferences and thus make reading easier.

While designing this typographic family, we determined key parameters to allow the user to more easily adjust the readability to their needs.


OT Carta Straight Mono is monospaced font with straight edges, it comes with the Standard version witch consists of six cuts (Thin, Light, Regular, Medium, Bold, Black) and four widths (One, Two, Three, Four) with appropriate italics (oblique). Each font consists of 400 characters, a character set that supports most of Latin based languages.

We wanted to avoid adding excessive visual elements to “improve” readability, so attention was paid to the diversity of similar characters such as 1Il, nu, 0O. As in all OMO type letters, symmetrically opposite letters bdpq can be additionally marked to avoid confusion when reading. This function is available through the Omoguru mobile app.
