Morse Code Chart
Everything on one sheet, laid out to print. Click any character to hear it first.
This page is the reference to pin above a desk. If you would rather understand how the code is built and how to learn it, the alphabet page explains the system behind these signals.

What is on the sheet
Seventy-three characters in five groups, which is more than most printed charts carry:
- 26 letters, A-Z. International Morse code, the standard set in ITU-R M.1677-1 and used in aviation, at sea and in amateur radio.
- 10 digits, 0-9. Each one is exactly five signals long, which makes the numbers the most regular part of the whole code.
- 18 punctuation marks. Full stop, comma, question mark, slash and the rest, including the at sign the ITU added in 2004.
- 12 accented letters. From national practice rather than the international standard, which is why a few of them share a signal.
- 7 prosigns. Procedural signals such as SOS, AR and SK, sent as one unbroken run with no gaps between the letters.
Most charts stop after the letters and digits. If you only need those two groups, the Morse code alphabet page explains the system behind them; this sheet is the full reference to pin up.
How to read it
A dot is one unit long and a dash is three. Inside a character the gap is one unit, between characters three, and between words seven. Those five numbers are the entire timing system - the chart gives you the patterns, the rhythm gives them meaning.
That is also what a chart cannot show. The symbols are on paper, but the spacing is what a listener actually hears, and the duration of one unit is the only thing that changes when the speed changes. At 20 words per minute a dot lasts 60 milliseconds; at 10 WPM it lasts 120, and every other duration scales with it. Press a character to hear the timing instead of reading it.
The printed version drops the colors and the play buttons and arranges the characters in six columns, which fits an A4 sheet without shrinking the text.
Print it or save it as a PDF
The print button opens your browser's print dialog. From there you have both options:
- On paper, pick portrait and normal margins. The layout is built for one A4 or Letter sheet and does not need scaling.
- As a PDF, choose Save as PDF in the destination list instead of a printer. Every current browser offers it, on desktop and on phones, and the download lands in your usual folder.
There is no separate file to download here, and that is deliberate: a PDF generated by your own browser matches what you see, while a pre-made one drifts out of date the moment the chart is corrected. Print it, copy it, hand it out in a class - the code follows an international standard and is nobody's property.
Frequently asked questions
-
Is this Morse code chart free to print and share?
Yes. Print it, copy it, hand it out in a class. The chart follows the international standard ITU-R M.1677-1, which is not anyone's property.
-
Why does the printed page look different?
The print stylesheet removes the navigation, the tools and the background colors, and lays the characters out in six columns. That keeps everything on one sheet and saves ink.
-
Does the chart include accented letters?
Yes, along with prosigns. Accented letters come from national practice rather than the international standard, so a few of them share a code.
-
How many characters are on the chart?
Seventy-three: 26 letters, 10 digits, 18 punctuation marks, 12 accented letters and 7 prosigns. The international standard itself covers the first three groups; the other two are added here because they turn up on the air.
-
Why do Morse code charts on different sites disagree?
Three reasons, and only the first is a real difference. Some charts show American Morse, the older railway and landline code, whose letters are genuinely different. Some leave out punctuation and prosigns. And some print accented letters that were never internationally agreed, where two countries assigned the same signal to different letters. For the 26 letters and 10 digits of international Morse there is no disagreement at all.
-
Why are some punctuation marks missing from other charts?
Because they are rarely sent. Punctuation runs to five, six or seven signals, so operators write stop instead of a full stop and skip the rest. The marks are part of the standard and are all on this sheet, but you will hear very few of them in an actual contact.
