Help in Morse Code
“Help” in Morse code is .... . .-.. .--.: the letters H, E, L and P sent as 13 signals, 10 dots and 3 dashes. “Help me” adds -- . after a word gap. In a real emergency, though, the signal every radio operator recognizes is SOS (...---...), which is shorter and does not depend on English. Below you can hear and copy both, see each letter broken down, and learn when to send which.
What Does Help Look Like in Morse Code?
Copy-paste version: .... . .-.. .--.. In written Morse, a single space separates letters and a slash (/) separates words. When you send it as sound, light or taps, the space becomes a pause three dots long. Every pattern here follows the International Morse Code defined in ITU-R Recommendation M.1677-1, the same standard used by ham radio operators today (see the official Morse code standard).
Letter-by-Letter Breakdown
| Letter | Morse | Typed | Signals | Easy to confuse with |
|---|---|---|---|---|
| H | · · · · | .... | 4 dots | S ... (one dot less) and 5 ..... (one more) |
| E | · | . | 1 dot | Disappears into the next letter if the gap is short |
| L | · – · · | .-.. | 3 dots, 1 dash | F ..-., its mirror image |
| P | · – – · | .--. | 2 dots, 2 dashes | J .--- and W .-- |
| M (me) | – – | -- | 2 dashes | O --- (one dash more) |
The gaps carry as much meaning as the signals. Run the letters of HELP together and you get ......-...--., which reads just as well as 5 L P (..... .-.. .--.). That is why the pause between letters must be clearly longer than the pause inside a letter. More on this in how to decode Morse code without spaces, and every letter is in the Morse code alphabet chart.

Mayday · spelled out
-- .- -.-- -.. .- -.-- · a voice call, not a Morse signal
Mayday literally means “help me”. It comes from the French venez m’aider (“come help me”), was proposed by Frederick Stanley Mockford, the radio officer at London’s Croydon Airport, in 1923, and was adopted as the radiotelephone distress call by the 1927 International Radiotelegraph Convention in Washington. It is meant to be spoken three times on voice radio. In Morse code the distress signal is SOS, so spelling out MAYDAY in dots and dashes (17 signals) is slower and less recognizable than ...---... (9 signals). For any other phrase, use the Morse code translator or the list of common words and phrases in Morse code.
Help vs SOS: Which Should You Send?
| HELP | SOS | |
|---|---|---|
| Pattern | .... . .-.. .--. | ...---... |
| Signals | 13 (10 dots, 3 dashes) | 9 (6 dots, 3 dashes) |
| Length | 37 timing units | 23 timing units |
| Status | An ordinary English word | International distress signal since 1 July 1908 |
| Receiver needs | The Morse alphabet and English | Only to recognize one pattern |
| Hard to mishear | Five similar letters nearby (S, 5, F, J, W) | Symmetrical, unmistakable rhythm |
Send SOS when someone may be in danger
SOS was agreed at the first International Radiotelegraph Convention in Berlin, signed in November 1906, and took effect on 1 July 1908. It was chosen because three dots, three dashes and three dots are easy to send and almost impossible to mistake, not because it stands for anything; “save our souls” was attached later. It is keyed as one continuous signal with no letter gaps, which is also why it is quicker than HELP. The full story is on the SOS in Morse code page.
Send HELP when the receiver reads Morse words
HELP works between people who both know the Morse alphabet: friends practising, a puzzle or escape room, a game, a message to someone you know will decode it. It also makes sense as a second message after SOS, when you want to say what kind of help you need, followed by a word such as INJURED or a location.
How Long Does It Take to Send Help?
Morse timing is measured in units: a dot is 1 unit, a dash 3, the gap inside a letter 1, the gap between letters 3 and the gap between words 7. HELP adds up to 37 units, HELP ME to 55, and SOS, sent as one signal, to 23. One unit lasts 1200 ÷ WPM milliseconds, so:
| Speed | Help | Help me | SOS | Typical sender |
|---|---|---|---|---|
| 5 WPM | 8.9 s | 13.2 s | 5.5 s | Tapping, blinking, a beginner |
| 10 WPM | 4.4 s | 6.6 s | 2.8 s | Flashlight, careful hand-sending |
| 18 WPM | 2.5 s | 3.7 s | 1.5 s | Translator default speed |
| 20 WPM | 2.2 s | 3.3 s | 1.4 s | Experienced radio operator |
Repeat the message with a long pause in between, so a listener who catches it halfway can wait for the start. The maths behind these numbers is in Morse code timing and words per minute.
How to Send Help Without a Radio
With a flashlight or phone light
Turn the light on briefly for a dot and about three times longer for a dash, with darkness between every signal. Point it straight at the person or aircraft you want to reach and keep each flash steady; a light swept around is hard to read. Ships have signalled the same way for over a century with Aldis lamps, as described in Morse code at sea.
By tapping or knocking
Use a quick tap for a dot and a press about three times longer for a dash. If you can only knock, make dashes heavier than dots and agree on it if you can. Leave a clear pause after each letter. HELP has four letters to get right; if the listener may not know Morse, tap SOS instead. Step-by-step technique: how to send Morse code by tapping or blinking.
With a whistle, horn or beeper
Short blasts for dots, long blasts for dashes. Sound carries further than shouting and uses far less energy. Say it to learn the rhythm: “di-di-di-dit, dit, di-dah-di-dit, di-dah-dah-dit”. Outdoors, three blasts in a row is also a widely taught call for help, so a listener who does not know Morse may still understand.
By blinking
A quick blink is a dot and a held blink is a dash. It is slow, at roughly 5 WPM HELP takes about 9 seconds, and only works if the other person is watching closely. The best-known case is US Navy pilot Jeremiah Denton, who as a prisoner of war in 1966 blinked T-O-R-T-U-R-E during a filmed interview. Blinking is also how some accessibility devices use Morse code.
Frequently Asked Questions
What is help in Morse code?
“Help” in Morse code is .... . .-.. .--.. H is four dots, E is one dot, L is dot-dash-dot-dot and P is dot-dash-dash-dot, with a short pause between letters.
What is help me in Morse code?
“Help me” is .... . .-.. .--. / -- .. It is HELP followed by a word gap, then M (two dashes) and E (one dot). It has 16 signals in total.
Is SOS the same as help in Morse code?
No. HELP is an English word spelled letter by letter, while SOS (...---...) is the international distress signal, in force since 1908. SOS is shorter, sent as one continuous pattern, and recognized by operators who do not speak English.
How many dots and dashes are in help?
HELP uses 13 signals: 10 dots and 3 dashes. HELP ME uses 16: 11 dots and 5 dashes.
How do you tap help in Morse code?
Tap four quick dots for H, one for E, then dot-dash-dot-dot for L and dot-dash-dash-dot for P, pressing about three times longer for each dash. Pause after every letter. If the listener may not know Morse, tap SOS instead: three short, three long, three short.
Does Mayday mean help?
Yes. Mayday comes from the French venez m’aider, “come help me”. It is the spoken distress call on voice radio, adopted in 1927, and is said three times. In Morse code the equivalent is SOS, not MAYDAY spelled out.
