What is the difference between this chart and the alphabet page?

The alphabet page (/morse-code-alphabet/) focuses on learning the 26 letters with NATO phonetics, mnemonics and a quiz. This chart page is the complete reference: letters, numbers, punctuation and prosigns on one page, designed for quick lookup and printing.

How do I read the dot-dash patterns?

Each pattern reads left to right. A dot (·) is one time unit, a dash (−) is three units. Click any card on this page to hear its exact sound. The timing section below explains the gaps between signals, letters and words.

Are prosigns different from regular letters?

Yes. Prosigns like SOS (...---...) are sent as one continuous sequence with no gaps between the letter groups — that is what makes them instantly recognisable as special signals rather than plain text.

Is this chart free to use?

Completely free, no account or signup needed. Print it, share it, or use it in a classroom — no attribution required, though a link back is always appreciated.

Letters A–Z

Click any letter to hear its Morse code. E (·) and T (−) are the shortest — just one signal each.

Numbers 0–9

Every digit is exactly 5 signals. They form mirror pairs: 1↔9, 2↔8, 3↔7, 4↔6, with 5 (·····) and 0 (−−−−−) as anchors.

Punctuation

The 16 ITU punctuation marks. The most used: period (·−·−·−), comma (−−··−−) and question mark (··−−··).

Prosigns

Procedural signals sent as one continuous burst with no letter gaps — that is what makes them special.

Timing Rules

The five rules that make Morse readable. Everything is measured in units of one dot length.

Dot (·)	1 unit	The basic time unit
Dash (−)	3 units	Three times a dot
Gap within a letter	1 unit	Between dots and dashes of one character
Gap between letters	3 units	Between characters
Gap between words	7 units	Between words
