Morse Code Alphabet: A to Z Letters with Audio and Chart
View all 26 International Morse Code letters, click any card to hear its pattern, search by letter or Morse code, and save a clean A–Z chart for reference.
Download a PNG chart or print the alphabet directly from your browser.
This A–Z reference uses International Morse Code letter mappings. A dot is a short signal and a dash is three times as long as a dot.
International Morse Code Alphabet A to Z
The Morse Code Alphabet assigns every English letter from A to Z a unique pattern of dots and dashes. These patterns let the same letter be sent by sound, light, radio, tapping, or another clear short-and-long signal.
Use the interactive alphabet above when you want to look up a letter, hear its signal, copy the code, or compare patterns by length. The chart is limited to A–Z so the page stays focused on alphabet learning.

How to Read Morse Code Letters
Each Morse letter is made from one to four signal elements. A dot is the short element and a dash is the long element.
For example, A is .-, so it is sent as one short signal followed by one long signal.
N is the reverse pattern, -..
Dit and Dah Pronunciation
Morse code is often spoken as dit for a dot and dah for a dash. When a dot ends a character, it is commonly spoken as dit.
- A
.-dit dah - D
-..dah di dit - K
-.-dah di dah - R
.-.dit dah dit - S
...di di dit
Click any letter in the interactive chart above to hear the actual timing instead of relying only on the written pattern.
Learn the Morse Alphabet by Signal Length
Grouping letters by the number of signals can make the A–Z chart easier to scan and practice.
. and -
.- .. -- -.
Eight letters use three elements.
Twelve letters use four elements.
The filters above let you isolate these groups, then click each letter to hear its pattern.
Useful Morse Code Letter Patterns to Notice
Some letters become easier to remember when you compare related patterns rather than memorizing 26 isolated codes.
Single Signals
E is . and T is -.
Reverse Pair
A is .- while N is -..
All Dots
I is .., S is ..., and H is .....
All Dashes
M is -- and O is ---.
Alternating Pattern
K is -.- and R is .-..
Common SOS Letters
S is ... and O is ---.
How Morse Code Letter Timing Works
The dots and dashes only show the pattern. Correct timing gives those patterns their audible structure.
ITU-R Recommendation M.1677-1 defines a dash as three times the duration of a dot, with one-dot spacing between parts of the same character, three-dot spacing between characters, and seven-dot spacing between words.

How to Practice the Morse Code Alphabet
A chart is useful for reference, but listening and recall are more useful when your goal is to recognize Morse without looking it up.
Start With Short Patterns
Begin with E, T, A, N, I, and M before adding longer letter patterns.
Listen Before Looking
Click a letter, hear the signal, then try to identify it before checking the card.
Mix Similar Letters
Practice pairs such as A/N, K/R, and the all-dot sequence I/S/H.
Move to Words
Once individual letters feel familiar, practice short words instead of isolated characters.
Use the trainer for repeated listening and recognition practice.
Use the Alphabet With Other Morse Code Tools
The alphabet works best as a reference. Use the dedicated tools when you need to convert a full message.
Frequently Asked Questions
What is the Morse Code Alphabet?
The Morse Code Alphabet is the set of dot-and-dash patterns assigned to letters A through Z in International Morse Code.
How many letters are in the Morse code alphabet?
The A–Z English alphabet reference contains 26 letters. Each letter has its own Morse pattern made from one to four dots and dashes.
What is A in Morse code?
A is .-, which is one dot followed by one dash.
What is Z in Morse code?
Z is --.., which is two dashes followed by two dots.
Which Morse code letters have only one signal?
E is a single dot . and T is a single dash -.
Are Morse code letters case-sensitive?
No. Uppercase and lowercase forms of the same English letter use the same Morse code pattern.
Does the Morse alphabet include numbers?
International Morse Code also defines numbers, but this page keeps the A–Z alphabet separate. See Morse Code Numbers for 0 through 9.
Can I hear each Morse code letter?
Yes. Click a letter in the interactive A–Z chart above to hear its pattern. You can also change the playback speed from 5 to 40 WPM.
Can I download a Morse Code Alphabet chart?
Yes. Use the Download PNG button above to save the A–Z chart, or use Print Chart to print a clean reference from your browser.
Is this International Morse Code?
Yes. The letter mappings on this page follow International Morse Code.
