Morse code tattoos: how to check the code before the ink
To check a Morse code tattoo, decode it from the final artwork, not from your notes. Cover the original message, read the dots and dashes one letter at a time against an alphabet chart, then have someone who has never seen the message do the same, and type what the artwork shows into a decoder. If all three give you the same words, the code is right.
The errors to watch for are few: letters that run together, a dot too many or too few, a letter swapped for its mirror, or a design read from the wrong end. All of them are easy to catch on paper and hard to fix afterward, so the checking is worth an evening.
Start from the standard written form
Before anyone draws anything, write the message the standard way:
- Write it in capitals: BREATHE, or LET IT BE.
- Look up each letter in a chart of International Morse, the code used on radio and taught today. If a chart shows spaces inside letters such as C or O, it is American Morse, an old landline code, and the patterns differ. Do not mix the two.
- Write each letter’s pattern with one space between letters and
/between words.
BREATHE comes out as -... .-. . .- - .... ., and LET IT BE as .-.. . - / .. - / -... ..
Keep this text version safe. It is your reference at every step: what you check, what you hand the artist, and what you compare the final drawing against. How to write Morse code in text covers the conventions in more detail.
If the message includes a date, remember that every figure is five symbols long, from 1 as .---- to 0 as -----. A four-figure year is twenty symbols, longer than most words.
Spacing that holds up on skin
Morse timing gives a ready-made set of proportions, and they work on paper and skin as well as in sound:
| Part | Width, in dot-widths |
|---|---|
| Dot (dit) | 1 |
| Dash (dah) | 3 |
| Space inside a letter | 1 |
| Space between letters | 3 |
| Space between words | 7, or a slash |
Drawn with exactly these widths, and a seven-width space rather than a slash between words, a message is as many dot-widths long, end to end, as it is units long in timing, which makes sizing easy. BREATHE is 51 dot-widths from end to end. If one dot-width is 2 mm, the design is about 10 cm long.
Treat the proportions as a starting point and talk to your artist about the rest. Tattoo artists often warn that marks set very close together can blur into each other as a tattoo ages, so ask how much space your design needs at the size you want. If it has to be shorter, scale the whole design down, within what your artist says will hold up, rather than squeezing the gaps. The gaps are the first thing a tight layout sacrifices, and they are the part that carries the meaning.
Two more things help a design stay readable for years. Make the dashes unmistakably longer than the dots, so nobody has to judge a 2 to 1 difference on a curved wrist. And keep the space between letters clearly wider than the space inside a letter: a reader should see the groups before counting anything.
Marking letter and word breaks
The space between letters is the most important mark in the design, and the one most likely to shrink when artwork is resized or bent to fit a curve. Take it out of a short word and the symbols can be read many ways: AN, .- -., becomes .--., which is also P, WE or ATE.
For word breaks you have a few clean options:
- A wide space, about seven dot-widths. The most faithful to the code.
- A slash or a short vertical line. This matches the written convention, so anyone decoding with a chart will understand it.
- One word per line. Stacking the words removes the word gap entirely. Each line still needs its letter spaces.
Whatever you choose, never separate letters with a mark that looks like code. A separator dot is read as an extra dit, and a short line between letters is read as an extra dah.
Decide which way it reads. Morse read backward is not the same message. BREATHE read from the other end becomes EHTNERV, because every letter reverses. This matters more on skin than on paper: a wrist or forearm tattoo that reads left to right for you reads upside down, and so right to left, for someone facing you. Choose who the tattoo is for, and make sure the start is obvious, for example by beginning it next to a natural line such as the edge of the wrist.
SOS is the one deliberate exception. As the distress signal it is a prosign, written ...---... with no letter breaks, one continuous character. If that is what you mean, leave the breaks out on purpose. With breaks, it reads as the letters S, O and S.
The errors that slip through
| Error | Example | How to catch it |
|---|---|---|
| Letters run together | AN drawn as .--., which also reads P |
Decode it cold from the artwork |
| A dot too many or too few | S ... drawn as H .... |
Count every run against the chart |
| Mirror letter | A .- drawn as N -. |
Decode left to right, slowly |
| Letter O for figure 0 | O --- in a date instead of 0 ----- |
Check figures are five symbols |
| Mangled text | Two hyphens turned into one long dash | Read the text version character by character |
| Wrong direction | BREATHE read as EHTNERV | Mark where the message starts |
The mirror pairs are worth a second look, because a design copied in a hurry flips them: A and N, D and U, G and W, B and V, F and L, Q and Y are each other backward. Morse letters that sound alike, and how to tell them apart has the full set of look-alikes.
The mangled-text error is easy to miss. Some apps quietly turn two hyphens into one long dash and three periods into a single ellipsis character, and a design copied from a message or a document can lose symbols that way. How to copy and paste Morse code so it reads right explains what to watch for.
A checklist before the ink
- Keep the text version of the message, made from a standard chart.
- Transcribe the final artwork back into text yourself: look at the drawing, not your notes, and write down every dot, dash, space and slash you see.
- Compare the two texts symbol by symbol. They should be identical.
- Decode the artwork cold. Cover the original message and read the drawing letter by letter with a chart.
- Ask someone else. Give a friend the drawing and a chart, and nothing else. If they read your message, so will strangers.
- Run your transcription through a decoder. A decoder only knows what the spaces tell it, so it catches a missing break that your eye fills in without noticing.
- Check the stencil on your skin from the angle people will read it, before the needle starts.
- Wait a day and do steps 4 and 5 again. Fresh eyes catch what a long evening of checking does not.
For step 6 on a Mac, Dot & Dash has Morse to Text: type or paste dots and dashes, with spaces between letters and slashes between words, and the message appears as you go. It also accepts a middle dot or a bullet for a dit and an underscore for a dah, so a design noted down with bullets reads too. Its Text to Morse gives you the exact pattern to start from, and Play lets you hear it. The same checks, with lower stakes, apply to Morse code bracelets and jewelry.
Questions
Do Morse code tattoos need spaces between letters?
Yes. The space between letters is part of the code. Without it, the dots and dashes can be split into letters in many ways, and nobody can tell which word you meant.
How long should a dash be compared with a dot in a tattoo?
Morse timing makes a dash three times as long as a dot, and that is a good starting point for a drawing. What matters most is that dots and dashes are easy to tell apart on skin, so ask your artist how the design will look at your chosen size.
Can a decoder check my tattoo design?
Only the text you give it. Transcribe the final artwork into dots, dashes, spaces and slashes yourself, then decode that, so the check covers the drawing and not just your notes.
Does it matter which way up a Morse code tattoo is?
Yes. Read backward, every letter reverses, so a message that reads right from one side reads as different letters from the other. Decide who the tattoo should read for and make the starting point obvious.
