Morse Code Alphabet

Every character of international Morse code, from the ITU standard, in one chart. Under each letter is how it sounds (“di-dah”), which is how you should learn it. Print it for your desk or radio shack, and try any message in the Morse code translator.

Tips for learning the Morse alphabet

  • Learn sounds, not pictures. Say “di-dah” for A rather than “dot dash”. Experienced operators hear whole letters as rhythms; counting dots gets slow very quickly.
  • Start with the short letters. E (.), T (-), I (..), A (.-), N (-.) and M (--) are one or two signals long, and E, T, A, I and N are among the most common letters in English, so you can read real words early.
  • Use Farnsworth spacing. In the translator, keep the character speed around 18–20 WPM and lower the Farnsworth speed. You hear real letter rhythms with time to think between them.
  • Numbers follow a pattern. 1 to 5 start with dots and fill with dashes from the right; 6 to 0 start with dashes. Learn 1 and 6 and the rest fall into place.
  • Practice a little every day. Ten minutes of listening beats an hour once a week.

Morse code alphabet FAQ

How many letters are in the Morse code alphabet?

International Morse code covers the 26 letters A to Z, plus one accented letter, É. It also has codes for the numbers 0 to 9, 13 punctuation marks and several procedural signals.

What is the easiest way to learn Morse code?

Learn by sound, not by counting dots. Two well-known methods: Farnsworth, where letters are sent at full speed with long gaps between them, and Koch, where you start with just two letters at full speed and add one more each time you copy them with 90% accuracy.

Is there Morse code for the exclamation mark?

Not officially. The ITU standard has no exclamation mark. Many amateur radio operators use -.-.-- (the letters KW), but some older tables list no code at all, so spell it out when it matters.

What are prosigns?

Procedural signals: short codes sent as a single run, without the gaps between letters, that manage a conversation. For example AR (.-.-.) ends a message, SK (...-.-) ends the contact, and K (-.-) invites the other station to send.
