The studio typesets each printed edition like a trade book: justified text hyphenated in the edition's language, no widows or orphans, running heads with your name and the title, page numbers, and every chapter opening on a right-hand page.
Dyslexia-friendly type: in a paperback's or hardcover's Settings, choose Type: Dyslexia-friendly for a book that's easier to read for readers with dyslexia or low vision, following the British Dyslexia Association's style guide: Atkinson Hyperlegible Next, a sans-serif the Braille Institute made for legibility, a size larger than the classic type, lines one and a half apart, lines left ragged rather than justified, no word broken across two lines, and a little more space between words. The book takes more pages, so build it again before you make its cover. Cream paper helps too.
The font sets Latin letters only, so editions in Cyrillic, Greek, Japanese and other scripts keep the classic type. Ebooks have no type style: readers choose their own font and spacing in their reading app.
