Problem Statement

Feature request

Currently the Claude Code VS Code extension has no way to change the font size of
the chat panel on its own. The only workaround is window.zoomLevel / Cmd+= zoom,
which scales the entire VS Code UI rather than just the Claude panel. The panel also
does not respect editor.fontSize.

Proposed solution

Add a dedicated setting, e.g.:

• claudeCode.fontSize — sets the font size (in px) of the Claude panel text, or
• claudeCode.webviewZoom — a zoom multiplier applied only to the Claude webview

This would let users increase the readability of the chat panel for accessibility /
high-DPI displays without enlarging the rest of the editor.

Current behavior

• No claudeCode.fontSize setting exists.
• The panel ignores editor.fontSize.
• Only window.zoomLevel affects it, which zooms the whole window.

Environment

• Claude Code for VS Code extension
• VS Code (desktop)

Proposed Solution

I'd like a dedicated setting for the Claude Code panel, independent from the global
window zoom, so I can make only the chat text larger without enlarging the rest of
the VS Code UI.

Ideal experience:

1. A setting claudeCode.fontSize (in px) and/or claudeCode.webviewZoom (a zoom

multiplier) available in the Settings UI and settings.json.

1. Keyboard shortcuts to zoom the panel while it has focus — e.g. Cmd/Ctrl + "+",

Cmd/Ctrl + "-", and Cmd/Ctrl + "0" to reset — affecting ONLY the Claude panel,
not window.zoomLevel.

1. The chosen size persists across restarts and applies live, without reloading the

window.

This would let me keep my editor at a comfortable size while making the Claude chat
panel more readable on a high-DPI display.
