What Is Braille Alphabet?
Braille is a tactile writing system designed to be read by touch rather than sight. It was invented by Louis Braille in 1824 when he was just 15 years old, building on an earlier military code called Night Writing. Braille standardised the way blind people access written language and is still the primary literacy system for people who are blind or have low vision worldwide.
The system is based on a cell of six dot positions arranged in a 2-column by 3-row grid. Each position is either raised or flat. The 64 possible combinations of raised and flat dots encode the letters of the alphabet, numbers, common words, punctuation marks, and musical notation. Extensions like Grade 2 Braille add contractions for faster reading.
Unicode includes the full Braille Patterns block (U+2800 to U+28FF), which assigns a character to every possible 8-dot Braille cell. This makes it possible to display Braille visually on screens — though reading Braille from a screen defeats its original purpose, it is useful for educational materials, accessibility awareness content, and generating Braille text for display.
How Braille Alphabet Works
Grade 1 Braille (also called uncontracted Braille) is a direct letter-by-letter encoding. Each letter of the alphabet has a specific dot pattern. For example, the letter A is a single raised dot in position 1. B adds a second dot in position 2. Each number reuses a letter pattern but is preceded by a number indicator symbol.
Grade 2 Braille introduces contractions — single cells or groups of cells that represent common words or letter combinations. "And" is one cell, "the" is one cell, "ing" is one cell. This shorthand reduces the physical length of Braille documents and improves reading speed. Most published Braille books use Grade 2. Online Braille converters typically produce Grade 1 output for simplicity.
Examples of Braille Alphabet
- ⠁ → A (dot 1)
- ⠃ → B (dots 1, 2)
- ⠉ → C (dots 1, 4)
- ⠓ → H (dots 1, 2, 5)
- ⠝ → N (dots 1, 3, 4, 5)
- ⠟ → Q (dots 1, 2, 3, 4, 5)
Where Is Braille Alphabet Used?
- Primary literacy for blind users: Braille is the main way people who are blind read books, menus, elevator buttons, and signage
- Educational materials: teachers and accessibility specialists use Braille converters to prepare educational content for blind students
- Accessibility awareness: sighted designers use visual Braille representations in campaigns and materials about disability inclusion
- Museum and product labelling: Braille labels on medicines, public signs, and exhibits are legally required in many countries
- Unicode Braille in text: the Unicode Braille Patterns block allows Braille to appear in digital documents, apps, and web pages
