Braille has groupings of dots knows as cells. Generally one cell is one letter. Each cell has space for six raised dots in two parallel rows, 3 dots per row. So for each 3 dot row there can be 0, or 3 (in the 123 position), dot can be in the number 1, or 2 or 3 position or 2 dots in the 12, 23, or 13 position – that is 8 ways. There are 2 rows so 8 X 8 is 64. There are 64 possible combinations. Each cell is a letter, number, punctuation mark, or certain common word.

There are three grades.

Grade 1 is where the word in spelled out. This is mainly seen in labeling. Kitchen and personal items use Grade 1 Braille.
