How Morse Code Encoding Works

Morse code represents each letter and digit as a sequence of two signal lengths: a dot (a short signal) and a dash (a long signal, conventionally three times the length of a dot). There's no separate symbol for a "pause"; spacing itself carries meaning. Standard spacing rules: the gap between dots and dashes within one letter is one unit, the gap between two letters is three units (shown as a single space by this tool), and the gap between two words is seven units (shown as a forward slash surrounded by spaces, " / ").

Common Use / History

Morse code was developed in the 1830s-40s for early telegraph systems and remained standard for maritime and aviation distress communication for over a century. Its best-known sequence is SOS (... --- ...), chosen not as an abbreviation for any phrase but because its pattern (three dots, three dashes, three dots) is simple to send and recognize even under poor signal conditions. It's still internationally recognized as a distress signal today. Outside of ham radio and maritime use, Morse code shows up in puzzles, signaling games, and accessibility tools. Some assistive-switch devices use dot/dash-style input.
