The Morse code alphabet at a glance

The Morse code alphabet assigns every letter from A to Z a unique sequence of dots (short signals, called dits) and dashes (long signals, dahs). This chart shows the International Morse Code standard used worldwide by amateur radio operators, pilots, sailors and anyone who wants to send a message with sound or light. Each card above is interactive: click or tap a letter and you will hear it played at your chosen speed, exactly as a radio operator would send it.

If you only remember one thing, make it this: the most common English letters have the shortest codes. E is a single dit, T a single dah, and I, A, N, M are all two signals long. Samuel Morse's assistant Alfred Vail reportedly worked this out by counting the type in a printer's case, and that efficiency is still baked into the alphabet 180 years later. For numbers see the Morse code numbers chart; to translate whole messages use the Morse code translator.

How to use the chart

  1. Click a letter to hear it

    Each card plays the letter at the current speed. Try E, T, then S and O — those four cover the famous SOS and give you a feel for the rhythm.

  2. Adjust the speed

    20 words per minute is standard. Slow down to 10–12 WPM when you are starting out, but try to keep each letter as one sound rather than counting dots.

Patterns that make the alphabet easier to learn

  • Opposites: several letters are mirror images of each other — A (.-) and N (-.), D (-..) and U (..-), B (-...) and V (...-), G (--.) and W (.--). Learning them in pairs halves the work.
  • Families: E, I, S, H are 1–4 dits; T, M, O are 1–3 dahs. Hearing the count is easier than it sounds once you stop counting and start feeling the length.
  • Frequency = brevity: the letters you meet most in English (E, T, A, O, I, N) all have one or two signals. Rare letters like Q, J, Y and Z get four.
  • Rhythm, not dots: radio operators never say “dot dash”; they say di-dah. Sound the codes out loud — “di-dah” for A, “dah-di-di-dit” for B — and the alphabet sticks faster.

Frequently asked questions

What is the Morse code alphabet?

It is the set of 26 dot-and-dash sequences that represent the letters A to Z in International Morse Code, the standard defined by the International Telecommunication Union. Together with the ten digits and a handful of punctuation marks it lets you spell out any message as sound, light or vibration.

How many letters are in Morse code?

International Morse covers the 26 letters of the basic Latin alphabet. Some languages add accented letters (for example Ä, Ö, Ü, É, Ñ) with their own national codes, but they are not part of the international standard and most translators — including ours — mark them as unsupported.

What is the easiest way to memorise the Morse code alphabet?

Learn by sound, not by sight. Start with a few letters (E, T, A, N, I, M), practise until you recognise them instantly, then add a few more — this is the idea behind the Koch method. Keep the speed at 15–20 WPM so each letter is one rhythmic sound rather than a string of countable dots.

Our practice trainer plays random letters for you to type, and the beginner's guide explains the full routine.

Is Morse code the same in every country?

The International Morse Code alphabet is the same everywhere and is what this chart shows. A different, older system called American Morse was used on US landline telegraphs in the 19th century and has several different letters. Read more in International vs American Morse code.

Which letters are the shortest in Morse code?

E (one dit) and T (one dah) are the shortest. I (..), A (.-), N (-.) and M (--) follow with two signals each. The longest letters — such as J, Q, Y, Z and the digits — are four or five signals long.
