Morse Code Letters — All 26 at a Glance
Every letter of the alphabet in International Morse code, A through Z. Each character is a unique sequence of dots and dashes — no two are the same. Click any letter below to hear it played as a clean radio tone, exactly as it sounds on the air.
How letter codes are structured
Morse assigned the shortest codes to the most common English letters. E is a single dot — the quickest possible signal. T is a single dash. Move outward from there and you get the two-element letters: A .-, I .., M --, N -.. The 26 letters fan out in a logical tree you can visualise — it's one of the fastest ways to memorise the code.
Learning tips
The most common mistake is trying to count dots and dashes visually. Instead, learn each letter as a sound rhythm. Say the mnemonic aloud: "di-dah" for A, "dah-di-di-dit" for B. Once five or six letters are automatic, add more one at a time. The interactive Morse learner is built exactly for this — it plays each character at real speed and tracks your progress.
Related character sets
The 26 letters are the core of International Morse, but the full character set also includes numbers 0–9, punctuation marks, and a small set of accented letters used in European languages. The full alphabet reference covers all of these together with a printable layout.
Frequently asked questions
What are the shortest letters in Morse code?
E (a single dot) and T (a single dash) are the shortest. They were deliberately assigned the briefest codes because they are the most common letters in English, keeping telegraph transmissions fast.
Are Morse code letters the same in every country?
International Morse code — the standard shown here — is used worldwide for radio and aviation. An older American Morse code, used on 19th-century US landline telegraphs, uses different patterns for several letters. Outside of historical study, International Morse is what you need.
How many elements does the longest letter have?
Several letters use four elements: B (-..), C (-.-.), F (..-.), H (....), K (-.-), L (.-..), Q (--.-), R (.-.), V (...-), X (-..-), Y (-.--), and Z (--..). None of the standard 26 letters exceeds four elements.
What is the difference between a dit and a dah?
A dit (dot) is the basic unit of time — one beat. A dah (dash) lasts exactly three dits. The gap between elements inside a letter is one dit; the gap between letters is three dits; and the gap between words is seven dits.
