Ekkamai New Typeface
Custom Thai & Latin Type Design — 2.5M+ Combined Downloads
Designing a Thai typeface is one of the most demanding typographic challenges — 44 consonants, 15 vowels, 4 tone marks, and a stacking system that demands pixel-level precision at every weight.
Ekkamai New is a geometric sans-serif covering the full Thai script alongside a matching Latin character set, available in 3 free weights with a 7-weight + italics commercial family. The design balances mechanical consistency with the organic flow that Thai readers expect, using uniform stroke widths and open counters for screen legibility.
Released for free on f0nt.com, the four-font family — WDB Bangna (2013), Bangna New (2015), Ekkamai Standard (2018), and Ekkamai New (2019) — has been downloaded over 2.5 million times combined, each generation refining letterforms and expanding the character set.
