Complete Morse Code Alphabet Chart
Every character has its own dot-and-dash pattern. A dot is one timing unit and a dash is three. For example, A is .- (di-dah), N is -. (dah-dit), S is ... (di-di-dit), and O is --- (dah-dah-dah).
The chart follows International Morse code. Use the Play button to hear a character, Copy to reuse its written pattern, or print the page as a compact study sheet.

Prosigns are compact Morse signals used to manage message flow.
| Prosign | Morse | Meaning | Actions |
|---|---|---|---|
| SOS | ...---... | Distress signal, sent as one continuous pattern | |
| AR | .-.-. | End of message | |
| AS | .-... | Wait | |
| BT | -...- | Separator | |
| HH | ........ | Correction | |
| KN | -.--. | Go only, specific station | |
| SK | ...-.- | End of contact | |
| VE | ...-. | Understood |
How to Space Morse Code
Keep a one-unit pause between the dots and dashes inside one character, a three-unit pause between letters, and a seven-unit pause between words. In plain text, this site uses one space between letters and a slash between words.
For example, HELLO is .... . .-.. .-.. ---, while HELLO WORLD places a slash between the two words.
SOS: Letters vs. Continuous Signal
When written as three letters, SOS appears as ... --- .... The formal distress signal is sent continuously as ...---..., without normal letter gaps. The pattern is distinctive because it combines three short, three long, and three short signals.
Standard and Accuracy
The characters and timing on this page are checked against the International Telecommunication Union recommendation for International Morse code. See the source notes or the International Morse code reference for standards, timing, and operating signs.
Frequently Asked Questions
What is A in Morse code?
A is dot dash, written as .-.
What is the Morse code for numbers?
Numbers use five-signal patterns, such as 1 as .---- and 0 as -----.
Can I print this Morse code alphabet?
Yes. Use Print / Save as PDF to print the chart or save it as a PDF from your browser.
