Localize App Store Screenshots to Vietnamese
Tiếng Việt
Vietnam = ~100M people, one of SEA's fastest-growing app markets.
Why Vietnamese matters
Vietnam's ~100M people form one of Southeast Asia's fastest-growing, most mobile-first app economies, where users bank, shop, and stream almost entirely on phones. Vietnamese uses the Latin-based chữ Quốc ngữ alphabet but can stack two marks on one letter (a vowel diacritic (â ê ô ơ ư ă) plus one of five tone marks), so it needs more vertical line-height than English despite sharing the alphabet.

Localization tips for Vietnamese
- 1 Raise line-height ~15-25%. A single letter can carry a vowel diacritic and a tone mark (ế, ộ, ữ), and at tight leading the tone clips the line above.
- 2 Require full Vietnamese coverage: the horn vowels ơ/ư, the đ, and precomposed tone combinations (ầ ẫ ợ ự). Many "Latin" fonts have base accents but drop these.
- 3 Prefer precomposed (NFC) Unicode over combining sequences; decomposed input renders with floating, mis-placed tone marks in some rendering pipelines.
- 4 Address the reader as "bạn" (neutral, friendly "you"); intimate pronouns like mày/tao read as rude in marketing, and copy skews warm but respectful.
- 5 Width barely grows (~10-15% vs English). Your real layout risk is vertical tone-mark clipping, not horizontal overflow.
- 6 Northern (Hanoi) and Southern (Saigon) Vietnamese differ mostly in speech; the written standard is shared, so a single listing serves the whole country.
Fonts for Vietnamese
Be Vietnam Pro (designed for Vietnamese), Noto Sans, and recent Inter. All cover ơ, ư, đ plus stacked tone marks (ậ, ệ, ợ). Verify the tone mark sits crisply over the horn vowels and doesn't collide with the letter above; older webfonts often mis-position it or fall back mid-word.
Most common mistake
Using a font that covers base Latin accents but drops Vietnamese-specific marks: the horn vowels ơ/ư, the đ, or stacked tone marks. Tones are phonemic: ma, má, mà, mả, mã, and mạ are six different words, so a missing mark doesn't just look wrong, it changes the meaning.
Vietnamese localization FAQ
What App Store Connect locale code should I use for Vietnamese?
Use vi when adding Vietnamese (Tiếng Việt) screenshots in App Store Connect or Google Play Console. Using the wrong code means your localized screenshots never reach Vietnamese users.
Does text expansion affect Vietnamese screenshot design?
Vietnamese runs +20% vs English on average character count. You should design buttons and headlines with explicit overflow headroom, because text that fits in English will break in Vietnamese.
Does Shotlingo automatically localize screenshots to Vietnamese?
Yes. Shotlingo auto-translates your App Store screenshot text to Vietnamese (Tiếng Việt) with AI that respects text expansion, and platform-appropriate fonts. Export the localized bundle ready for App Store Connect locale vi.
Do I have to translate my App Store screenshots to Vietnamese?
If Vietnamese is a major market for your app, yes. Unlocalized screenshots significantly reduce conversion, because users scroll past copy they cannot read. Even partial localization (headlines only) typically beats English-only.
