| A standard braille cell consists of six dots arranged in three rows and two |
| columns. Each dot can be specifically identified by its number as follows: |
| |
| === ============ === ====== |
| Dot Position Row Column |
| --- ------------ --- ------ |
| 1 top-left 1 1 |
| 2 middle-left 2 1 |
| 3 bottom-left 3 1 |
| 4 top-right 1 2 |
| 5 middle-right 2 2 |
| 6 bottom-right 3 2 |
| === ============ === ====== |
| |
| Computer braille has introduced a fourth row at the bottom. |
| |
| === ============ === ====== |
| Dot Position Row Column |
| --- ------------ --- ------ |
| 7 below-left 4 1 |
| 8 below-right 4 2 |
| === ============ === ====== |

| A picture may make this numbering convention easier to understand:: |
| |
| 1 o o 4 |
| 2 o o 5 |
| 3 o o 6 |
| 7 o o 8 |
