Braille was developed by Louis Braille in the beginning of the 19th century. 6 dot Braille letters, common punctuation marks, and a few symbols are displayed as raised 6 dot Braille cell patterns read by using a fingertip to feel the raised dots. The 6 dot Braille alphabet, the method for representing braille numbers, and some braille punctuation marks are used in all languages that share the Roman alphabet. There are variations of 6 dot Braille in various Roman alphabet languages. Representation of punctuation marks and differences in the meanings of other 6 dot Braille cells are commonly used to represent special characters and/or common letter combinations.

Braille characters are based on a 6 dot Braille cell having two parallel columns of three dots each. If the empty cell is counted, 64 unique dot combinations are possible with a 6 dot Braille cell. Dot height is approximately 0.02 inches (0.5 mm); the horizontal and vertical spacing between dot centers within a braille cell is approximately 0.1 inches (2.5 mm); the blank space between dots on adjacent cells is approximately 0.15 inches (3.75 mm) horizontally and 0.2 inches (5.0 mm) vertically. A standard braille page is 11 by 11 inches and typically has a maximum of 40 to 42 braille cells per line and 25 lines.
