A length limit is a constraint placed on the target text for a UI string, subtitle line, button label, or other rendered element so that it fits the space or time available in the interface or media player. In localization documentation it is usually expressed as a maximum number of characters per string, pixels per line, or characters per second for subtitles.
Length limits appear in localization kits for mobile apps, desktop software, and game UI, and in subtitling specs for timed media. Translators see them as character-count columns in a CAT tool, as max-length metadata attached to strings, or as reading-speed and line-length rules in a subtitling convention.
The most damaging error is expanding the source text to make a translation read naturally while ignoring the limit, which can cause truncated buttons, overflowing menus, or subtitles that disappear too fast. Translators sometimes also confuse character limits with pixel limits, producing strings that pass validation but still break at runtime.
For creative and consumer content the failure mode is flatness, not inaccuracy — and flatness passes an accuracy check. Terms here also carry technical constraints (reading speed, character budgets) that are part of the brief.
Angel Translation locks terms like this into a project terminology base before expert review begins, so the same source term resolves to the same target term across every document in a submission — and stays consistent in the next revision. See the 8-step AI + expert workflow.
