Kedmanee vs Pattachote: Thailand's Two Keyboard Layouts Explained
If you have ever switched a phone or laptop into Thai, you have almost certainly been typing on Kedmanee without knowing it. But Thailand actually standardised two Thai keyboard layouts, and the second one — Pattachote — was designed from scratch to be faster. This guide explains how they differ, compares their home rows key by key, and helps you decide which is worth your time.
Two layouts, one alphabet
Thai has 44 consonants plus a large set of vowels, four tone marks, and its own digits — far more symbols than fit on the base layer of a keyboard. Both Kedmanee and Pattachote solve the same problem: they spread those characters across the base and Shift layers of a standard QWERTY-shaped board. They simply make very different choices about where each character goes, and those choices are what you feel in your fingers after a few hundred words.
Kedmanee: the default everyone uses
Kedmanee (เกษมณี) is the layout pre-installed on virtually every computer, phone, and operating system that supports Thai. Because it is the default, it is what schools teach, what offices use, and what you meet on any borrowed device. Its character placement grew out of the mechanical Thai typewriter era rather than from an efficiency study, so a few very common letters sit in awkward reaches — but its ubiquity is a genuine, practical advantage that no amount of ergonomic theory overcomes.
Pattachote: the efficient challenger
Pattachote (ปัตตโชติ) was developed later as a deliberately ergonomic alternative. The design goal was to put the most frequent Thai letters on or near the home row and to balance the workload between the two hands — much the same idea behind Dvorak for English. On paper it reduces finger travel. In practice it never displaced Kedmanee, so support, teaching materials, and shared muscle memory are all much harder to come by.
The home rows, side by side
The clearest way to see the design difference is to look at what each layout puts under your resting fingers. Reading the eight home keys plus the two inner reaches (left to right across A S D F G H J K L ;):
- Kedmanee home row: ฟ ห ก ด เ ้ ่ า ส ว — a mix of common letters (ก, า, เ, ห, ด, ส, ว) inherited from the typewriter, with the two everyday tone marks ่ and ้ falling under the right index finger.
- Pattachote home row: ้ ท ง ก ั ี า น เ ไ — note that two pre-posed vowels (เ and ไ) and two more vowels (ี, ั) sit on the home row alongside high-frequency consonants ก, น, ง, ท, exactly as the efficiency design intended.
Each key shows its base character on top and its Shift character below. The coloured top border marks which finger presses the key:
- Left pinky
- Left ring
- Left middle
- Left index
- Right index
- Right middle
- Right ring
- Right pinky
- Thumb
Both layouts agree on ก and า — two of the most common characters in Thai — but Pattachote pulls more of the highest-frequency letters into home reach, while Kedmanee keeps its tone marks close instead. Neither is wrong; they optimise for different things.
Why Kedmanee won anyway
Layouts are a network-effect technology: the more people use one, the more valuable it is to use the same one. Kedmanee was already standard when Pattachote arrived, so every new device shipped with Kedmanee, every typing class taught Kedmanee, and every borrowed keyboard spoke Kedmanee. A measurably better layout still loses if switching means abandoning every machine you do not personally own. This is the same reason QWERTY outlived its English challengers.
What switching actually costs
Relearning a layout is not a weekend project. Your existing muscle memory actively fights the new positions for the first week or two, and your speed drops to beginner levels before it recovers. That cost is only worth paying if you type Thai for hours every day on hardware you control. For everyone else, the hours are better spent getting genuinely fast on the layout that is already everywhere.
Which should you learn?
For almost everyone, the answer is Kedmanee. You will type on any device without reconfiguring it, and every tutorial and class assumes it. Consider Pattachote only if you type Thai for many hours a day on your own equipment and are willing to invest weeks of slower typing for a long-term comfort gain.
- Learn Kedmanee for maximum compatibility and the shortest path to typing anywhere.
- Consider Pattachote if you are a heavy daily typist optimising your own setup and value ergonomics over portability.
- Whichever you pick, commit to one — splitting practice between both slows the muscle memory for each.
ThaiTyper supports both layouts, so you can try each for a few minutes and feel the difference before deciding. Most learners start on Kedmanee, settle into the home row, and never look back.
