How to Read Morse Code: Full Alphabet Chart

To read Morse code, translate each group of dots and dashes into a letter using the chart below, then read the letters in order. A dot is a short beep (say “dit”) and a dash is a long beep three times its length (say “dah”). Letters are separated by a short gap and words by a longer one. For example .... .. is HI. You can hear and decode any message with the Morse code translator, but the chart and timing rules below let you read it by ear or by hand.

TL;DR

• Dot = short (“dit”); dash = long, 3× a dot (“dah”).
• Gap inside a letter = 1 unit; between letters = 3 units; between words = 7 units.
• Speed is measured in words per minute (WPM), calibrated on the word PARIS.
• SOS is ... --- ... sent as one continuous group.
• This is International (ITU) Morse code, the worldwide standard.

Morse Code Alphabet Chart (A–Z)

These are the International Morse code letters, defined by the ITU in Recommendation ITU-R M.1677. Read left to right: letter, then its code.

Numbers (0–9)

Digits are always five symbols long, counting up in dots then flipping to dashes.

Timing: The Real Key to Morse

Morse is built on one unit of time. Everything else is a multiple of it, which is why timing — not just the pattern — is what makes a message readable.

• Dot: 1 unit.
• Dash: 3 units.
• Gap between dots and dashes within a letter: 1 unit.
• Gap between letters: 3 units.
• Gap between words: 7 units.

Speed is quoted in words per minute (WPM). The standard reference word is PARIS, which is exactly 50 units long including the trailing word space, so at 20 WPM one unit is 60 ms. Beginners often use Farnsworth timing: the dots and dashes are sent at a fast character speed, but the gaps between letters and words are stretched, so you learn the real sound of each letter while still having time to decode.

Common Words and Signals

SOS is written with no gaps between the letters (...---...) because it is treated as a single prosign, which makes it unmistakable in an emergency.

How to Send and Receive

• Sending: keep your unit length consistent. A wobbly rhythm is harder to read than slow, even timing. Count “dit” for a dot and “dah” for a dash in your head.
• Receiving: learn letters by their sound, not by counting dots. Experienced operators hear “dah-dit-dah-dit” as C, not as dash-dot-dash-dot.
• Practice with high character speed and wide gaps (Farnsworth) so you never fall into the counting habit.
• Light, sound, or tapping all work — Morse is about the timing pattern, not the medium.

FAQ

How do I memorize Morse code fast?

Learn it by sound in small groups and use Farnsworth timing so each letter’s rhythm is distinct. Avoid memorizing a visual dot-dash chart, which trains you to count instead of hear.

Is Morse code still used?

Yes. It is still used in amateur radio, aviation and marine navigation beacons, and as an accessible signaling method. SOS remains a recognized distress signal.

What is the hardest part of learning Morse?

Timing, not the alphabet. Most beginners get the patterns quickly but struggle to keep an even unit length and to hear letters as sounds rather than counting symbols.

Why is SOS three dots, three dashes, three dots?

It was chosen because it is simple, symmetric, and unmistakable, sent as one continuous group with no letter gaps. It does not officially stand for any words.

Beginners think Morse is a chart to memorize. Operators know it is a rhythm to hear: once a letter has a sound, you stop reading dots and start reading words.
