How do I choose fonts that are legible within speech bubbles in a comic book?

Legibility is crucial. Avoid overly ornate or thin fonts. Bold, clear fonts with good spacing are best. Consider the size of the speech bubble – smaller bubbles require simpler fonts. Test the font at the intended size and with typical dialogue to ensure it's easily readable. Outlining the font (creating a stroke) can also improve readability, especially against busy backgrounds.
