Lettering in Two Languages: Text Fitting, Font Licences and Balloon Reflow

Localisation begins before the finished balloon

A translated line rarely occupies exactly the same amount of space as its source. English dialogue may become longer in another language, or a short phrase may require more characters once grammar and natural phrasing are preserved. The shape of the text also changes. Different scripts have different proportions, punctuation conventions and word-breaking behaviour. A balloon designed around one language can become crowded when another is inserted without layout adjustments.

For a weekly webtoon, the translation workflow should begin while the episode is being prepared, not after every balloon has been finalised. Keep dialogue in an editable document or structured text file, with speaker names, panel references and context notes. This gives translators and letterers a shared reference. It also reduces the chance of a translated line being placed in the wrong balloon after panels are moved during production.

• Record the original dialogue and panel reference.
• Identify character voice and scene context.
• Leave space for likely text expansion.
• Keep translation notes separate from finished artwork.

Text fitting is a visual decision

Text fitting means adjusting dialogue so that it sits comfortably within a balloon while remaining easy to read. It includes font size, line length, leading, alignment and the amount of breathing room around the words. A balloon should not be filled to its edges. The text needs enough internal space to remain legible on a phone screen, particularly when a reader encounters the episode at a reduced display size.

Consider a source line of 24 words that becomes 31 words in translation. Shrinking the font to force the new line into the original balloon may make it uncomfortable to read. Instead, test several line breaks, adjust the balloon shape or move a nearby visual element if the composition allows. If the dialogue still feels cramped, consider whether the translated sentence can be naturally shortened without losing meaning. That decision belongs to the translator and editor, not an automatic text-fitting tool.

Choose fonts for legibility and language coverage

A comic lettering font needs to support the characters, punctuation and special marks used in the target language. A font that looks suitable for English may lack accented letters, extended punctuation or an entire writing system. Missing glyphs can appear as empty boxes or substitute symbols, disrupting the balloon and changing the intended reading experience.

Check the actual font files, not just the promotional specimen. Confirm that the family includes the required scripts and that its weights are suitable for dialogue, emphasis and sound effects. Review punctuation spacing, numerals and the appearance of capital letters. If the series uses several languages, a compatible font family may provide a more consistent visual identity, although individual scripts may still need different sizes or line spacing.

• Confirm support for every required character.
• Inspect punctuation and accented letters.
• Check bold and italic weights where needed.
• Review line spacing at mobile reading size.
• Keep sound effects visually distinct from dialogue.

Read the font licence before commercial publication

Comic lettering fonts are software products, and their licences can place conditions on how the files are used. A free download does not automatically mean unrestricted commercial permission. Some licences allow personal projects but restrict commercial work. Others permit commercial artwork while imposing conditions on embedding, redistribution, modification or use in applications. The exact wording and scope vary between foundries and individual font files.

For a professional series, identify the licence attached to the specific font and retain a copy with the production records. Check whether the permitted use covers commercial comics, digital publishing, client work, font modification and distribution of files containing the font. Embedding a font in an application or distributing the actual font file can be treated differently from publishing a flattened image containing rendered lettering. When the licence is ambiguous, the foundry or a qualified licensing professional is the appropriate source for clarification.

Reflow balloons without breaking the panel

Balloon reflow is the process of changing the text arrangement and sometimes the balloon itself to suit a new language. A wider balloon can accommodate longer dialogue, while a taller balloon may preserve the panel's horizontal composition. Both choices affect the artwork. A balloon that covers a character's face, hides an important prop or disrupts the order of speech can weaken a scene even when every translated word fits.

Work from the panel's visual hierarchy. Identify faces, gestures, movement directions and important environmental details before changing balloon placement. Keep the dialogue order obvious, particularly when two characters speak in quick succession. For vertical-scroll comics, also consider how a balloon's position affects the distance between panels. A larger balloon may require additional vertical space and can change the timing of the next reveal.

• Preserve the original reading order.
• Keep faces and important actions unobstructed.
• Allow enough internal space around the text.
• Check balloon tails against the correct speaker.
• Review the entire scroll after reflow.

Use AI-assisted tools carefully in the translation pipeline

AI lettering tools can assist with text recognition, extraction, preliminary translation and some layout tasks. They may reduce repetitive copying or help identify dialogue regions in a large batch of pages. However, text recognition can confuse handwritten sound effects, stylised lettering and small punctuation marks. Translation systems can also miss humour, social relationships, wordplay and references that depend on earlier episodes.

Treat automated output as a working draft. A human translator should resolve meaning, voice, cultural context and terminology. A letterer should then confirm that the dialogue fits the actual panel. Preserve the original script and keep an editable translation file so corrections can be made without rebuilding the page. Before uploading unpublished artwork or dialogue to a generative service, read the current terms for training, retention, commercial use and deletion. Permission to process a file does not automatically answer every question about its future use.

Build a repeatable two-language production hand-off

A bilingual workflow works best when translation, lettering and artwork remain connected through stable panel references. The writer supplies the source script with speaker identification and context. The translator returns approved dialogue and notes on phrases that require additional space. The letterer fits the new text and flags any panel where the balloon must change substantially. The editor resolves questions about meaning or pacing before the final export.

For example, a seven-day episode schedule could reserve the first three days for scripting, thumbnails and drawing, the fourth for translation preparation, the fifth for approved dialogue and lettering, the sixth for balloon corrections and language review, and the seventh for export and publication checks. If the translation requires extensive rewriting, the schedule needs a larger hand-off window. Create a shared glossary for names, titles, recurring objects and character-specific expressions before the next episode enters production.

• Keep source and translated scripts in separate editable files.
• Use stable panel identifiers for every dialogue line.
• Maintain a shared terminology glossary.
• Approve translated wording before final balloon placement.
• Export and inspect each language as a separate reading experience.
