Morse Code Alphabet

What Is the Morse Code Alphabet?

The Morse code alphabet maps each Latin letter (A–Z) to a unique pattern of short signals (dots / dits) and long signals (dashes / dahs). The chart on this page uses International Morse code — the ITU standard still used in amateur radio, aviation beacons, maritime backup signalling, and learning apps worldwide.

Unlike a static image, this Morse code alphabet chart is interactive: click a letter to hear its rhythm, switch to numbers or punctuation, copy the table, or type a word to see the full encoding instantly.

Morse Code Alphabet a to Z (Complete Chart)

Every letter below is the official International mapping. Memorise by sound when you can — the play buttons above train recognition faster than reading alone.

Morse Code Numbers 0–9

Each digit uses exactly five symbols. Use the Numbers tab in the tool to hear them. Full dedicated numbers calculator coming on its own URL; the mappings below are already complete for reference and copy/paste.

Morse Alphabet Timing Rules

Correct spacing is part of the alphabet’s meaning. If timing is wrong, letters blur together.

• Dot = 1 time unit
• Dash = 3 units
• Gap inside a letter = 1 unit
• Gap between letters = 3 units
• Gap between words = 7 units

On this chart, WPM controls how fast those units play when you click a character or use Play all. Deep dive: Morse code timing.

Morse Code Alphabet Explained

International Morse assigns each Latin letter a unique dit/dah pattern so operators can send text by sound or light. It is a timing alphabet: meaning comes from element length (dot vs dash) and the gaps between elements, letters, and words.

Why Sound Beats a Printed Chart

Charts answer “what is the Morse for X?” Listening answers “what letter did I just hear?” Use play buttons here, then the quiz and practice trainer.

Pattern Families (Not A→Z)

Group by structure: one-element (E, T), two-element mirrors (A/N, I/M), three-element (S, O, U, R, W, D, K, G), then longer letters. Frequency order (E, T, A, N, I, M, S, O…) beats alphabetical memorisation. Full path: learn Morse code.

Letters vs Numbers vs Prosigns

Letters vary from 1–4 elements. Digits are always five — see Morse numbers. Procedural signals (AR, SK, BT) are continuous patterns — see prosigns, not this A–Z table.

How to Learn the Morse Code Alphabet (Fast)

1. Start with the Shortest Letters

Learn E (.), T (-), I (..), M (--), A (.-), N (-.), S (...), O (---) first. They appear often in English and teach dit/dah timing.

2. Study by Pattern Groups, Not A→Z Order

Group 1-signal, 2-signal, then 3–4-signal letters. Pattern families stick better than alphabetical lists.

3. Prefer Sound Over Pictures

Click letters here daily. Operators recognise rhythm (“di-dah”) faster than visual dots on a page.

4. Encode Tiny Words Next

Practice HI, SOS, YES, NO, CAT with the mini converter, then open the full Morse code translator for longer messages and light/audio practice. Use the practice trainer and Morse quiz to test recognition.

Common Morse Alphabet Mix-Ups

These lookalike pairs cause most beginner errors — listen for the whole rhythm, not a dot count.

• E (.) vs T (-) — shortest pair; mix length, not count.
• A (.-) vs N (-.) — mirrors of each other.
• I (..) vs M (--) — two dits vs two dahs.
• S (...) vs H (....) — three vs four dits; keep them even.
• S vs 5 (.....) — five dits is the digit; letters stop at four for H.
• B (-...) vs 6 (-....) — digit adds one more dit.

Common Alphabet Queries Answered

What Is ABC in Morse Code?

A .- · B -... · C -.-. → together: .- -... -.-.

How Do You Write SOS with the Alphabet?

S = ..., O = ---, S = ... → ... --- ... (the international distress pattern).

Can I Copy-Paste the Morse Alphabet Chart?

Yes — use Copy chart on the active tab (letters, numbers, or punctuation), or select the HTML tables below for documents and printouts.

Is This American Morse or International?

International Morse only. American Morse is historical and obsolete for modern radio use.
