How to Read Morse Code
To read Morse code, split it into words (at each / or long gap) and letters (at each space), then look up each group of dots and dashes. By ear, short beeps are dots, long beeps are dashes, and the pauses show where letters and words end.
How do you read written Morse code?
- Find the words. Words are split by a slash (/) or a big gap.
- Find the letters. Inside a word, each letter is split by a single space.
- Count the symbols. Letters have 1 to 4 symbols. Numbers always have 5.
- Look each one up. Use the Morse code alphabet or a printable chart.
Worked example
Let us read: .... . .-.. .--. / -- .
| Code | Symbols | Letter |
|---|---|---|
| .... | 4 dots | H |
| . | 1 dot | E |
| .-.. | dot dash dot dot | L |
| .--. | dot dash dash dot | P |
| / | new word | (space) |
| -- | 2 dashes | M |
| . | 1 dot | E |

How do you read Morse code by sound?
- Short beep = dot ("dit"). Long beep = dash ("dah"), about three times longer.
- Short pause = same letter continues. Medium pause = next letter. Long pause = next word.
- Do not count dots in your head. Learn each letter as a whole sound. The trainer helps with this.
- For a recording you cannot follow, use the audio decoder.
Common beginner mistakes
- Missing spaces: .. ... is "IS", but ..... is "5".
- Mixing up opposites: A (.-) and N (-.) look alike. Read in order, left to right.
- Losing count of dots: S (3 dots), H (4) and 5 (5) are easy to confuse. Group them in your head.
Questions people ask
How do you read Morse code for beginners?
First split the code into letters (single spaces) and words (slashes or long gaps). Then look up each group of dots and dashes in the alphabet. Start with short groups: one dot is E, one dash is T.
How do you tell letters apart when listening?
By the pauses. Inside a letter, the pause is as long as a dot. Between letters it is three times longer, and between words it is seven times longer.
What is "dit" and "dah"?
They are the spoken names for dot and dash. Saying "di-dah" for A helps you remember the sound of the letter instead of the picture of dots and dashes.
