Malayalam script consists of a total of 578 characters. The script contains 52 letters including 16 vowels and 36 consonants, which forms 576 syllabic characters, and contains two additional diacritic characters named anusvāra and visarga.[57][58] The earlier style of writing has been superseded by a new style as of 1981. This new script reduces the different letters for typesetting from 900 to fewer than 90. This was mainly done to include Malayalam in the keyboards of typewriters and computers.

In 1999 a group named "Rachana Akshara Vedi" produced a set of free fonts containing the entire character repertoire of more than 900 glyphs. This was announced and released along with a text editor in the same year at Thiruvananthapuram, the capital of Kerala. In 2004, the fonts were released under the GNU GPL license by Richard Stallman of the Free Software Foundation at the Cochin University of Science and Technology in Kochi, Kerala.

Malayalam has been written in other scripts like Roman, Syriac[59][60][61] and Arabic. Suriyani Malayalam was used by Saint Thomas Christians (also known as Nasranis) until the 19th century.[59][60][61] Arabic scripts particularly were taught in madrasahs in Kerala and the Lakshadweep Islands.[62][63]
