Speech Bubble Text Fit FAQ

Production answers without the guesswork

Does this tool rewrite comic dialogue?+

No. It changes font size and line breaks only. The original wording remains untouched.

How does speech bubble text fitting work?+

The tool subtracts padding, uses the inner width for rectangular bubbles or the full line-box chord for oval and thought bubbles, then greedily wraps words and tests font sizes until the complete layout fits.

Can it preserve manual line breaks?+

Yes. Turn on Preserve line breaks to keep every explicit newline while the font size is fitted.
