Localizing your app listing into Tamil

Storefronts and localization names read from Apple’s App Store localizations reference; language codes and field limits from Google Play’s translation language list and each store’s field reference. Checked August 29, 2026.

One of the eleven Indian languages Apple supports in the India storefront, and one of the few with a substantial diaspora audience in Singapore, Malaysia and Sri Lanka.

Three bytes per character means roughly 33 characters of Apple keyword field — Tamil words are long, so this field fills fast.

Where a Tamil listing appears

Apple publishes the default language of all 173 App Store storefronts, and Tamil is the default in none of them — it is an additional supported language in 1. Those markets see English unless you add the Tamil localization yourself.

What you translate, and what it costs you

Both stores cap the same fields, and neither cap changes by language — but the amount of meaning you fit inside them does. Apple’s keyword field is the one that surprises people: it is measured in bytes, so Tamil at about 3 bytes per character leaves roughly 33 characters. Google Play counts characters instead, and says so explicitly: its limits “apply to both full-width and half-width characters”.

The screenshots are part of the localization

Both stores let you upload a separate screenshot set per localization, and in practice the captions are what sells — a translated description under English screenshots converts like an English listing. Design the frames once, then export the same layout per language rather than rebuilding it: that is the difference between localizing into Tamil in an afternoon and not doing it at all.
