I Love You in Morse Code: Dots, Dashes, Sound, Tap & Light

“I love you” in Morse code is .. / .-.. --- ...- . / -.-- --- ..-. That is two dots for I, then L O V E, then Y O U, with a single space between letters and a slash between words. Copy it or press Play below to hear it at a gentle speed.

The phrase has 8 letters in 3 words, made of 24 signals: exactly 12 dots and 12 dashes. The rest of this page breaks it down letter by letter, shows where the gaps belong, and turns it into sound, taps and flashes.

The phrase at a glance

The unit count is what matters when you tap or flash the message by hand. International Morse code, as defined by the ITU in Recommendation ITU-R M.1677-1, measures everything in dot lengths: a dash is three dots, the silence inside a letter is one dot, the gap between letters is three dots and the gap between words is seven.

Add that up for this phrase and you get 93 units: 48 units of signal, 16 units of short silences inside letters, 15 units of letter gaps and 14 units of word gaps. Nearly half the message is silence, which is why spacing is the part most people get wrong.

Letter-by-letter breakdown

Each row below comes straight from the translator’s engine. The rhythm column spells the sound the way operators say it aloud: “dit” for a dot, “dah” for a dash, and “di” when a dot leads into another signal.

I

.. is just two dots. It is one of the shortest letters in the code, which makes the opening of the phrase quick and light. Send exactly two: a third dot turns I into S.

LOVE

.-.. --- ...- . is the busiest word. L is dot, dash, dot, dot. O is three dashes. V is three dots and a dash. E is a single dot.

The trap sits at the end: V finishes with a dash and E is one dot, so a rushed sender tends to run them together. Leave a full letter gap after V so the lone dot of E stands on its own.

YOU

-.-- --- ..- starts with Y, a dash, a dot, then two dashes. O is three dashes again, and U is two dots and a dash. Because Y ends on dashes and O is all dashes, the gap between them has to be clear, or the listener hears one long string of dahs.

Spacing: where the gaps go

The written form uses one space between letters and a slash between words, which is the notation our translator produces. When you send the phrase as sound, taps or light, those marks become silences of three different lengths.

1. Inside a letter: 1 unit. The pause between the two dots of I, or between the dash and dots of L, is as short as a dot.
2. Between letters: 3 units. After L, wait the length of a dash before starting O.
3. Between words: 7 units. After I, and again after LOVE, wait more than twice a letter gap.

Here is the phrase laid out as a sending plan. Read each line as one word, and treat the line break as a 7-unit pause.

If the word gaps shrink to the size of letter gaps, the listener receives ILOVEYOU as one long word. It is still readable for someone who knows the phrase, but it is no longer correct Morse. For the general rules behind these ratios, see the timing and spacing section on our homepage.

How long it takes to send

Because the phrase is always 93 units long, you can work out its length at any speed. The unit length in milliseconds is 1,200 divided by the speed in words per minute, so the maths is simple.

The slower rows look long, but they are realistic for a hand, a torch or a first attempt. A quick, even message is easier to read than a fast, uneven one.

Hear it: play the audio

Press Play on the block at the top of this page to hear the phrase as a Morse tone. Listening a few times is an easy way to learn it, because Morse is a rhythm before it is a pattern on paper.

Say it along with the sound: “di-dit, di-dah-di-dit dah-dah-dah di-di-di-dah dit, dah-di-dah-dah dah-dah-dah di-di-dah”. The commas mark the word gaps. You can also open the phrase in our translator to slow it down, change the tone, or loop it with Repeat until the rhythm sticks.

If the whole phrase feels too long to hold in your head, learn it one word at a time with the small play buttons in the breakdown above: I first, then LOVE, then YOU, and only then join them with word gaps.

How to tap I love you

Tapping is the most private way to send the phrase: on a table, a desk, or a partner’s hand. A tap is naturally short, so the question is how to make a long signal. Pressing and holding for about three times as long as a quick tap works best on skin or a soft surface, because the other person can feel the contact last.

The demonstration below pulses the phrase slowly and narrates each signal, so you can copy the rhythm with a finger.

1. I: two quick taps. Then rest for a word gap of 7 units, about as long as two holds with a short break between them.
2. L: tap, press-and-hold, tap, tap. Rest a letter gap of 3 units, as long as one hold.
3. O: hold, hold, hold. Letter gap.
4. V: tap, tap, tap, hold. Letter gap.
5. E: one tap. Then a word pause.
6. Y: hold, tap, hold, hold. Letter gap.
7. O: hold, hold, hold. Letter gap.
8. U: tap, tap, hold.

On a hard table a knock has almost no duration, so people either drag a fingertip for a dash or agree on another convention between themselves. That trade-off, plus drills for getting your gaps right, is covered in our full guide on how to tap Morse code.

How to flash or blink it

With a flashlight or phone torch, a dot is a short flash and a dash is a flash three times as long. The dark periods matter just as much: one unit between flashes inside a letter, three between letters, seven between words.

1. Pick a slow unit, for example half a second, and keep it steady.
2. Flash I as two short flashes, then stay dark for about three and a half seconds.
3. Flash LOVE letter by letter, staying dark for about one and a half seconds between letters.
4. Pause for the word gap again, then flash YOU.
5. Repeat the whole phrase once, after a long dark pause, so the watcher can confirm it.

Blinking with your eyes follows the same idea, a quick blink for a dot and a held blink for a dash, but eye blinks are hard to time and easy to miss. Keep it slow and expect the other person to already know the phrase.

For aiming, distance, covering the lens versus switching, and practice messages, read how to send Morse code with a flashlight. If you only want to watch the phrase flash, the translator’s Light playback flashes any message in time with the audio.

How to write it or wear it

In writing, the safest format is the one at the top of this page: dots and dashes, one space between letters, and a slash between words. Copy it with the Copy button rather than retyping it, because keyboards and phones like to turn two hyphens into a long dash or three dots into an ellipsis character.

If you want the phrase without word separators, for example on a narrow ring, write it with wider gaps between words instead of slashes. Anyone decoding it needs to be able to tell a letter gap from a word gap.

The phrase is popular as a tattoo and on bead bracelets because it is short and looks like an abstract pattern to anyone who cannot read Morse. Each format has its own spacing problems, such as dots merging in skin or beads needing separators. Our Morse code tattoo guide covers proportions and layout, and the Morse code bracelet guide plans bead counts. For I LOVE YOU, a bracelet needs 12 dot beads, 12 dash beads, 5 letter spacers and 2 word spacers.

Common mistakes

Most errors come from counting wrong or from gaps, not from forgetting the code. Here is what each slip actually turns the phrase into, decoded by the translator’s own engine.

A few more to watch for:

• Long signals that are not long enough. If your dash is only twice a dot, taps and flashes start to blur. Aim for three times.
• Mixing up Y and Q. Y is dash, dot, dash, dash; --.- is dash, dash, dot, dash. Both have three dashes and one dot, so check the position of the dot.
• Using spaces inside a letter. In writing, a space means “new letter”. Never put a space between the dots and dashes of one character.
• Retyped characters. An en dash, em dash or middle dot pasted from a design app will not decode as Morse. Copy from a translator output.
• Rushing the word gaps. When tapping or flashing, people speed up once they feel confident. Keep the 7-unit pause.

Related short messages

A few close variations come up often. They are shown here as single examples rather than a phrase list.

• I love you too simply adds - --- --- after a word gap, so the reply is 4 words.
• ILY sends only the initials as one three-letter group, .. .-.. -.--. It is short enough for a ring, but a reader has to know what the initials stand for.
• 88 is amateur radio shorthand for “love and kisses”. It is sent as the two digits ---.. ---.., each a dash-dash-dash-dot-dot group, and is listed in the CWops CW abbreviations sheet. See our guide to Morse code abbreviations for 73, 88 and other on-air shorthand.
• 143 is a number shorthand that counts the letters (1, 4 and 3), not Morse. Sent in Morse it is just the digits .---- ....- ...--, which a reader will decode as a number, not as a phrase.

Check it in the translator

Before you engrave, print or tattoo anything, paste your final text into a translator and decode it back. If the decoded text is exactly I LOVE YOU, with the words in the right places, the sequence is correct.

You can also use the Morse Code Translator to try your own version, such as a name after the phrase, and compare the timing before you send it by hand.
