Morse Code Chart

This Morse code chart collects every letter, digit and common punctuation mark in one place. Use it to look up a pattern, or to check a message before you send it.

Letters

Letters use one to four marks. The short patterns belong to the letters used most often.

Numbers

Every digit uses five marks. The pattern adds a dot at the front from 1 to 5, then adds a dash at the front from 6 back to 0. The Morse code numbers page walks through the sequence.

Punctuation and symbols

Most punctuation uses six marks. Because the patterns are longer, a single mistyped mark is easier to hear as a wrong character than to spot by eye.

Prosigns

Prosigns are procedural signals: short patterns sent as one unit, with no letter gaps. They are not written on a keyboard and do not appear in ordinary text.

How to read the chart

A dot is one unit long and a dash is three. Inside a letter the gap is one unit, between letters three, and between words seven. Keep those ratios and the message stays readable at any speed.

Speed is measured in words per minute using the word PARIS, which takes 50 units. One unit in milliseconds is 1200 divided by the WPM, so at 20 WPM a dot lasts 60 ms and a dash 180 ms.

The drill on this page draws from the letter and digit tables above. Press the key, choose what you heard, and the chart pattern appears under the answer.

Chart, alphabet or code table

People use the three names for the same set of patterns. This page is the full lookup. The Morse code alphabet explains how the letter patterns are built and which ones get confused, and the Morse code translator turns typed text into the same patterns.
