What is a Localization Style Guide?
A localization style guide is a project-specific document that defines how a game should sound in each target language — covering tone, register (formal vs. informal), character voice rules, cultural adaptation guidelines, and project-specific writing conventions. It is the primary reference for translators to ensure tonal consistency across all content.
What a Style Guide Contains
A game localization style guide typically covers: overall game tone (dark/serious, humorous, casual, heroic), register decisions (formal Sie vs. informal du in German; formal Lei vs. informal tu in Italian; Anda vs. kamu in Indonesian), character voice profiles (how each major NPC sounds, their speech patterns, quirks, and vocabulary restrictions), cultural adaptation rules (how humor, references, and idioms should be handled), and formatting conventions (how numbers, dates, ellipses, and punctuation are used in the target language).
Style Guide vs. Translation Glossary
A glossary controls what things are called. A style guide controls how things are said. Both are needed. A glossary entry tells translators that ‘Shadow Strike’ is called ‘Schattenschlag’ in German. A style guide tells them that the warrior character who uses it speaks in a formal, archaic register and avoids contractions. Neither document replaces the other — together they enable consistent, high-quality localization across a full team.
Why Style Guides Matter for Game Dialog
Game dialog is where style guide absence is most visible. Without one, different translators naturally apply different tonal choices — one translates a character as formal and reserved, another as casual and direct. For games with 20+ named NPCs and tens of thousands of dialog lines, uncontrolled tonal variation accumulates into a game that feels inconsistent and poorly localized, even if individual translations are technically accurate.
When to Create a Style Guide
Style guides should be created before translation begins — ideally during project kickoff. For games with significant dialog content, SandVox creates character voice sheets for all major NPCs as part of the style guide. For live-service games, the style guide is a living document that grows as new characters and content types are added.
SandVox and Localization Style Guide
SandVox creates project-specific style guides for all narrative and dialog-heavy localization projects. For clients with long-term live-service content, style guides persist across years of updates — ensuring that characters added in Year 3 sound consistent with how they were written at launch.

Frequently Asked Questions
Who creates the localization style guide?
Style guides are most effective when built collaboratively — the developer provides creative direction (game tone, character descriptions, target audience) and the localization partner formalizes it into language-specific guidelines. SandVox builds style guides during project kickoff by reviewing source content, identifying tonal patterns, and establishing rules before translation begins.
Do I need a style guide for a small indie game?
Even small games benefit from a basic style guide. At minimum, documenting register decisions (formal vs. informal), tone (serious vs. humorous), and a few character voice notes takes a few hours and prevents inconsistencies that players will notice. A full style guide is more critical for dialog-heavy games regardless of production scale.
Can a style guide be applied retroactively?
Yes, but it’s more work. If inconsistencies exist in an already-translated game, a style guide combined with a revision pass can address them. We regularly do style-based revision passes for clients who want to bring older localization into line with current standards.
How long does it take to create a localization style guide?
A basic style guide for a single language takes 4–16 hours depending on project complexity. Multi-language projects require separate style guide sections per language — the total effort scales with language count. Style guides for narrative-heavy or character-rich games take longer due to the number of character voice profiles needed.
