 Plus Codes are characterized by their **code length**. This specifies the distance between the northern & southern bounds and the western & eastern bounds. Plus codes MUST use one of these code lengths:
 
-| Code length | North-south distance | West-east distance |  Precision   |
+| Code length | North-south distance | West-east distance | Longest edge |
