Frequently asked questions
How does the comic lettering checker estimate text fit?
It converts each text block into approximate visual width units, divides those units by the selected bubble width, and compares the result with the maximum line count.
Is the result a replacement for final typesetting?
No. It is an early preflight estimate. Font family, font size, balloon shape, line breaks, and letter spacing still affect the final fit.
Why are Chinese, Japanese, and Korean separate modes?
CJK characters use space differently from Latin words. The language modes apply small width adjustments so translation planning is more realistic.
Can I clean text from an existing comic page?
Yes. Use the linked Text Removal tool to clear existing lettering before rebuilding speech bubbles in Comic Studio.
