If you type Thai on a physical keyboard, you are almost certainly using the Kedmanee layout — the standard that maps Thai characters onto a QWERTY physical keyboard. This reference shows exactly which Thai character each key produces, both in the normal (unshifted) state and with Shift held down.
The Kedmanee layout and its two layers
Thai has 44 consonants plus dozens of vowel signs, tone marks, and special characters — far more than there are keys on a standard keyboard. Kedmanee solves this by placing two characters on each key:
Unshifted layer → common consonants and frequently used vowels
Shifted layer → less-common consonants, all four tone marks, punctuation
Each physical key (the letter printed on the key cap) carries one Thai character normally and a different one with Shift held. There is no third or fourth layer in everyday Thai typing — unlike some scripts that require additional modifier keys.
Typing order matters: consonant first, then vowel, then tone
Thai combining characters stack onto the consonant they modify, so the order in which you type them is important even though the marks appear visually above or below the letter:
- Type the base consonant (or the leading vowel if it precedes the consonant, such as เ or แ).
- Type the following vowel or vowels.
- If a tone mark is needed, type it last — it stacks onto the consonant as a combining character.
For example, to type ก้ (mid-class consonant ก with falling tone mark ้), you press the key for ก first, then Shift + the key that carries ้.
Why Kedmanee, not Pattachote?
The Pattachote layout was designed in the 1960s by Suth Pattachote to be more ergonomically balanced, placing vowels under one hand and consonants under the other, similar to Dvorak for English. Despite its design advantages, it never achieved widespread adoption. Kedmanee arrived first, was bundled with typewriters and early computers, and became the default — so virtually every Thai keyboard, every OS Thai input method, and every Thai typing course teaches Kedmanee. Pattachote remains a minority preference among fast typists who make an effort to learn it.
Phone keyboards and this reference
Mobile Thai keyboards display characters differently — they often merge the shifted layer behind a long-press, rearrange keys for thumb reach, or use a swipe input. But the underlying character set is the same Kedmanee standard, so this desktop grid remains the correct reference for which character maps to which physical key when you sit down at a desktop or laptop keyboard.
