Dubeolsik (두벌식) is the standard Korean keyboard layout, found on essentially every Korean computer and phone. It overlays the familiar QWERTY board: consonants live on the left hand, vowels on the right, mirroring the order jamo are typed within a syllable. This free reference draws the whole layout and lets you look up any key.
How it works
Each physical QWERTY key carries a base jamo and, on most consonant and a couple of vowel keys, a shifted jamo. The left-hand keys Q W E R T A S D F G Z X C V map to consonants like ㅂ ㅈ ㄷ ㄱ ㅅ ㅁ ㄴ ㅇ ㄹ ㅎ ㅋ ㅌ ㅊ ㅍ. The right-hand keys Y U I O P H J K L B N M map to vowels like ㅛ ㅕ ㅑ ㅐ ㅔ ㅗ ㅓ ㅏ ㅣ ㅠ ㅜ ㅡ.
Holding Shift turns the five plain stops/sibilant into their tense doubles — Q→ㅃ E→ㄸ R→ㄲ T→ㅆ W→ㅉ — and turns E→ㅒ and Y region vowels into their bright (yotised) variants ㅒ ㅖ. The live lookup below reports the base and shifted jamo for whatever Latin key you press.
Tips and notes
Because consonants and vowels are split by hand, comfortable Korean typing comes from alternating hands rather than rolling one side. Memorise the five Shift doubles first (ㅃㅉㄸㄲㅆ on Q W E R T) — they are the only Shift consonants you need. A standard US QWERTY keyboard is all you need; just toggle your OS input language to Korean.
