Design
Your words as bars drawn to true timing, the picture of the print.
Size
2480 × 3508 pixels, 300 dpi, with a margin for the frame.

Preview
A4The PNG and SVG are the print exactly as shown. Print saves as a PDF too: choose “Save as PDF” in the print dialog.
How to use
Choose a design: Message, Letters (each letter over its code) or Alphabet.
Type a name, a date or a short message; for Alphabet, add the phonetic words or the punctuation.
Pick a size: A4, US Letter, A3, a poster size from 8 × 10 to 18 × 24 in, or a social or wallpaper size.
Choose the colors, and whether to show a frame and the site name.
Press Print (choose Save as PDF for a PDF), or download the PNG or the SVG.
For a big print, take the PNG or the SVG to a print shop.
What it does
This Morse code poster maker draws your words, or the whole code, as a poster to print and frame.
- Your words in MorseMessage sets the words as a headline with the code under it; Letters puts each letter over its own code, like a printed key.
- An alphabet chartA to Z and 0 to 9, with the phonetic words (Alfa, Bravo …) and the 13 ITU punctuation marks if you want them, for a classroom or a radio room.
- Poster sizesA4, US Letter, A3, 8 × 10, 11 × 14, 12 × 18 and 18 × 24 in; square and story sizes for social posts, and phone and desktop wallpaper sizes too.
- Print, PNG or SVGPrint fills the page with no margins (social and wallpaper sizes are fitted to your paper); the PNG is drawn at up to 300 dpi; the SVG stays sharp at any size for a print shop, a cutter or an engraver.
- Seven color schemesDaylight, Night, White, Signal red, Navy, Paper and Forest, with a frame if you like.
- Shrinks to fitText and code shrink until the message fits the page, and the page tells you if it still can’t.
For a phone wallpaper of one word, use the Wallpaper maker.
How it works
Each print size is drawn at up to 300 dots per inch and under 16.7 million pixels, the largest canvas iPhone browsers draw, so a phone can make every size:
| Size | Inches | Pixels | dpi |
|---|---|---|---|
| A4 | 8.3 × 11.7 | 2480 × 3508 | 300 |
| US Letter | 8.5 × 11 | 2550 × 3300 | 300 |
| 8 × 10 in | 8 × 10 | 2400 × 3000 | 300 |
| 11 × 14 in | 11 × 14 | 3300 × 4200 | 300 |
| A3 | 11.7 × 16.5 | 3438 × 4861 | 294 |
| 12 × 18 in | 12 × 18 | 3336 × 5004 | 278 |
| 18 × 24 in | 18 × 24 | 3546 × 4728 | 197 |
For the three largest, the SVG has no pixels at all and prints sharp at any size.
Every letter uses International Morse code as set by ITU-R M.1677-1, the same table the translator uses. The poster draws each dot as a circle and each dash two and a half dots long, with letters spaced clearly apart.
The phonetic words are the ICAO spelling alphabet that NATO uses, so Alfa and Juliett are spelled that way on purpose (see the NATO phonetic alphabet).

Good questions
Frequently asked questions.
About Morse code posters
Can I print a Morse code poster for free?
Yes. Pick A4 or US Letter and press Print: the poster fills the page with no margins, and “Save as PDF” in the print dialog gives you a PDF.
For the bigger sizes, download the PNG or the SVG and print it at a print shop. There is no sign-up and no watermark; the site name at the foot can be turned off.
What size should I print?
A4 or US Letter for a home printer; 8 × 10, 11 × 14, 12 × 18 or 18 × 24 in, or A3, to fit a ready-made frame. Short words look boldest on any size, and a long message needs a taller page. The size line under the menu shows the pixels and the dpi.
Can I get it printed big at a print shop?
Yes. Take the SVG if the shop accepts it: it is a vector file, so it stays sharp at any size. Otherwise take the PNG; the sizes up to 11 × 14 in are drawn at 300 dpi, and the larger ones at 197 to 294 dpi.
What is the whole alphabet in Morse code?
Choose the Alphabet design to see A to Z and 0 to 9 with their codes, and add the punctuation if you need it. For a reference sheet to print, with sound for each letter, use the Morse code alphabet chart.
Can I draw a Morse code poster by hand?
Yes. For the standard proportions, make each dash three dots long and leave one dot of space inside a letter, three between letters and seven between words, as ITU-R M.1677-1 sets out for the sound. The poster itself draws each dash two and a half dots long with tighter gaps, which looks better on a wall, so trace the Letters design only if you want that look.
What does 3 dots mean in Morse code?
Three dots (...) are the letter S. Three dashes (---) are O, and three dots, three dashes and three dots make SOS, the distress signal. Type SOS with the Letters design to see each letter over its code, or see SOS for how the signal is sent and heard.
Is the Morse code on the poster correct?
Yes. Each letter uses International Morse code as set by the ITU-R M.1677-1 standard, the same table the translator uses.
The dots and dashes are drawn from that table, and the Letters design prints each letter over its code, so you can check them against the Morse code alphabet chart. Characters with no Morse code, such as emoji, are left out and listed under the text box.
Why did my message get smaller?
The text and the code shrink until the whole message fits the page. If it still can’t fit, the page tells you, so nothing is ever cut off without warning. Try a taller size or a shorter message.

Printing limits
Print takes the page size from the size you pick, but some printers can’t print to the edge and leave a thin white border. The phone sizes leave the top third clear for the clock.Who keeps it
