Sinhala input methods

Sinhala input methods are ways of writing the Sinhala language, spoken primarily in Sri Lanka, using a computer. Sinhala input methods can be broadly classified into two main groups: ones based on typewriter keyboard layouts, and ones that are meant to be typed on QWERTY keyboards using an input method, known as "Singlish".[1]

Wijesekara keyboard

The Wijesekara keyboard is the standard typewriter keyboard for the Sinhala script. This keyboard layout was first created and approved by the government of Sri Lanka in 1964.

In 2004, it was given the SLS standards as the Sri Lanka Sinhala Character Code for Information Interchange, SLS 1134 : 2004.[2]


The first standards compliant Sinhala Keyboard for Apple iOS was created by Bhagya Silva. This implementation featured a copyrighted custom layout that was based on SLS 1134:2004 optimised for mobile keyboards.[3]
