Game Dialogue and UI Text Character Count Design Guide

In game development, the character count design of dialogue and UI text is a critical factor that directly affects player experience. The optimal length varies by text type — dialogue windows, choice options, item descriptions, and tutorial prompts each have different requirements. When planning for international releases, localization-driven text expansion must also be factored in. This article covers the fundamentals and practical tips for designing game text.

Character Count Guidelines by Text Type

Text TypeRecommended LengthNotes
Dialogue window (1 page)40–80 charactersReadable in 2–3 lines
Choice text10–30 charactersShort enough to compare at a glance
Item name6–16 charactersMust fit inventory display
Item description30–80 charactersBriefly describe effects and uses
Quest description80–200 charactersInclude objective, conditions, and rewards
Tutorial text40–100 charactersBreak instructions into short segments
UI button label2–8 charactersIdeally a single verb
Loading hint20–60 charactersReadable during wait times

Dialogue Window Design

In RPGs and adventure games, the standard for dialogue windows is 40–80 characters (2–3 lines) per page. Players tend to skim rather than carefully read text, so keeping information per page minimal and maintaining a brisk pacing is essential.

Limit each page to a single message. When multiple pieces of information are packed into one page, players who rapidly press through dialogue risk missing critical content. Deliberately inserting short lines (10–20 characters) can also be an effective technique for conveying emotion or creating dramatic pauses.

Choices and Player Decision-Making

Choice text should be 10–30 characters. Overly long options slow down comparison and disrupt game pacing. Keeping all choices at similar lengths is also important — if one option is significantly longer than the others, players may assume it is the "correct" or "important" choice.

Two to four choices is the standard range. Five or more options crowd the screen and increase cognitive load. When a choice affects gameplay outcomes, include enough information in the wording for players to anticipate the consequences.

Text Expansion During Localization

When translating from Japanese to English, text volume typically increases by 1.2 to 1.5 times. German and French translations tend to be even longer, sometimes reaching 1.3 to 1.8 times the original Japanese length. Conversely, Chinese and Korean translations are often similar in length or slightly shorter.

When planning for localization, the standard practice is to reserve 30–50% extra space in UI text to accommodate post-translation expansion. Button labels and menu items are particularly affected — a 4-character Japanese label can easily become 12 or more characters in English. Implementing flexible-width layouts or automatic text scaling provides a safety net.

UI Text Design Principles

In-game UI text (buttons, menus, tooltips) demands both brevity and clarity. Button labels should ideally be a single verb — "Save," "Equip," "Sell." When two or more words are needed, aim for concise phrasing like "Use" rather than "Use Item."

Tooltips and help text should be 30–60 characters, providing a concise explanation of an action's result or effect. Tutorial text should stay within 40–100 characters per step, with instructions and explanations displayed separately so players can follow along without confusion.

Surprising Trivia

The total text volume of a major RPG can rival dozens of novels. For example, the localization of one open-world RPG reportedly involved approximately 1 million Japanese characters — equivalent to roughly 10 paperback books. Game text design is a writing project on par with literary works in scale.

Conclusion

Game text design is an essential process for maintaining player immersion and game pacing. Use 40–80 characters for dialogue windows and 10–30 characters for choices as baseline targets, adjusting for each text type. Remember to account for localization expansion margins.
