Dynamic Wide Content

Wide tables, diagrams, images, and code blocks without widening your prose.

Dynamic Wide Content fixes a common Obsidian annoyance: wide material gets squeezed, clipped, or forced into awkward wrapping by the readable line length.

The plugin keeps your prose exactly where it belongs: in Obsidian's comfortable reading column. Only genuinely wide blocks break out into a wider scrollable frame.

What It Does

• Preserves Obsidian's normal readable prose width.
• Expands only wide Markdown tables, code blocks, Mermaid diagrams, PlantUML diagrams, and image embeds.
• Adds horizontal scrolling inside the widened block frame when content is too wide for the pane.
• Works in Reading view and Live Preview.
• Does not require disabling readable line length globally.

Why This Exists

Readable line length is excellent for paragraphs, headings, lists, and normal notes. It is painful for wide content:

• pipeline or comparison tables
• architecture diagrams
• generated Mermaid and PlantUML output
• screenshots and reference images
• long code or log blocks

Dynamic Wide Content makes those blocks usable without turning every note into a full-width wall of text.

Settings

• Maximum wide content width: Controls how far wide blocks may expand.
• Viewport side margin: Keeps widened blocks away from the edge of the Obsidian pane.
• Widen tables: Allows Markdown tables to break out of the prose column.
• Widen diagrams: Allows Mermaid and PlantUML diagrams to use a wider frame.
• Widen images: Allows embedded images to display wider than prose.
• Widen code blocks: Allows preformatted code blocks to use a wider frame.
• Keep table cells on one line: Prevents wide tables from turning into tall, wrapped rows.
• Reading view support: Applies widening in Reading view.
• Live Preview support: Applies widening in Live Preview rendered embeds.
