Everything you need to know about manga speech bubbles — from basics to advanced styling
Manga bubbles (aka speech balloons or dialogue boxes) are the containers that hold character dialogue, thoughts, narration, and sound effects in manga and comics. They transform plain text into visual storytelling by conveying who is speaking, how they're speaking, and where the sound is coming from.
Unlike Western comics that often use plain rounded rectangles, manga bubbles come in wildly expressive shapes — jagged spikes for screaming, wobbly outlines for trembling, cloud-like shapes for thoughts, and jagged electric forms for telepathy or psychic powers.
Bangers for action/screams, Comic Neue for casual dialogue, Caveat for handwritten feel, Special Elite for typewriter/narration style
Manga often uses tighter letter spacing for a more authentic feel, especially in action text and SFX
Text often has a thick white or dark outline (stroke-width) so it stands out against busy backgrounds
For authentic manga reading, enable the "Vertical (manga)" option — text reads top-to-bottom, right-to-left
Scream and SFX text should be larger and bolder; narration can be smaller and lighter
Narration boxes typically use left alignment; dialogue uses center alignment for balance
