Reset Sizes for VS Code

A VS Code extension that provides a single command to reset all size-related changes (UI zoom, editor font zoom, terminal font zoom, and optionally size-related settings) back to defaults.

Features

• Single Command: Reset all zooms and size settings with one command
• Flexible Configuration: Choose exactly which VS Code commands to execute and which settings to reset
• Three Presets:
  • zoom (default): Resets zoom behaviors only (UI zoom, editor font zoom, terminal font zoom)
  • zoomAndSettings: Resets zooms AND removes size-related settings to restore VS Code defaults
  • custom: Define your own command list and settings to reset - fully customizable
• Safe & Reversible: Only removes custom setting values - you can always set them again
• Powerful Customization: Add any valid VS Code command to your reset workflow
• Scope Control: Choose which configuration scopes to reset (user, workspace, workspace folder)
• User-Friendly: Confirmations before changing settings, reload prompts when needed

What Gets Reset

The extension uses a preset system to control what gets reset. You can choose a preset or create your own custom configuration.

"zoom" Preset (Default)

Executes these VS Code commands:

• workbench.action.zoomReset - Reset UI zoom (overall window zoom level)
• editor.action.fontZoomReset - Reset editor font zoom (different from font size setting)
• workbench.action.terminal.fontZoomReset - Reset terminal font zoom

Settings modified: None

"zoomAndSettings" Preset

Executes the same zoom commands as above, PLUS removes your custom values for these settings:

• window.zoomLevel
• editor.fontSize
• editor.lineHeight
• terminal.integrated.fontSize
• terminal.integrated.lineHeight

What happens: VS Code will use its built-in default values for these settings. For example, if you had "editor.fontSize": 20 in workspace settings, it will be removed and the default (typically 12-14 depending on your OS) will be used.

Is it safe?: Yes! This only removes the custom values you've set. It doesn't delete any code, files, or extensions. You can always set these values again manually afterward.

"custom" Preset

With the custom preset, you define exactly which commands to execute and which settings to reset by configuring the resetSizes.commands and resetSizes.settingsToReset arrays in your settings.

Example: You could create a custom profile that only resets editor font size and executes a specific command you need.

Key Concepts

Zoom vs Font Size

VS Code has two different concepts for text size:

1. Font Zoom: Dynamic zoom controlled by Ctrl/Cmd + Mouse Wheel in editor/terminal

   • Temporary, per-session behavior
   • Not persisted in settings files
   • Reset by zoom commands

2. Font Size: The fontSize setting in settings.json

   • Permanent configuration
   • Persisted in settings files
   • Only reset in hardReset mode

UI Zoom

The window.zoomLevel setting controls the zoom of the entire VS Code window (all UI, not just text). This is different from editor/terminal font zoom.

Usage

Command Palette

1. Open Command Palette (Ctrl+Shift+P or Cmd+Shift+P on macOS)
2. Type "Reset All Sizes"
3. Press Enter

The extension will:

• Execute the configured VS Code commands (default: 3 zoom reset commands)
• (If settings are configured) Prompt for confirmation, then remove setting overrides
• Show a summary notification
• (Optional) Prompt to reload the window

Keyboard Shortcut

You can bind a keyboard shortcut to the command:

1. Open Keyboard Shortcuts (Ctrl+K Ctrl+S or Cmd+K Cmd+S on macOS)
2. Search for "Reset All Sizes"
3. Click the + icon and assign your preferred shortcut

Example keybinding in keybindings.json:

{
  "key": "ctrl+alt+0",
  "command": "resetSizes.resetAll"
}

Configuration

All settings are under the resetSizes namespace in VS Code settings.

resetSizes.preset

Type: string (enum: "zoom", "zoomAndSettings", "custom") Default: "zoom"

Choose a preset configuration:

• zoom: Resets zoom behaviors only (UI zoom, editor font zoom, terminal font zoom). No settings are modified.
• zoomAndSettings: Resets zoom behaviors AND removes custom size settings like editor.fontSize, terminal.integrated.fontSize, etc., restoring them to VS Code defaults.
• custom: Define your own command list and settings to reset using the commands and settingsToReset arrays.

{
  "resetSizes.preset": "zoom"
}

Tip: Use zoom for quick zoom fixes. Use zoomAndSettings when you want to clean up all size customizations. Use custom for full control.

resetSizes.commands

Type: array of string Default: ["workbench.action.zoomReset", "editor.action.fontZoomReset", "workbench.action.terminal.fontZoomReset"]

VS Code command IDs to execute when Reset All Sizes is run. You can add any valid VS Code command.

{
  "resetSizes.commands": [
    "workbench.action.zoomReset",
    "editor.action.fontZoomReset",
    "workbench.action.terminal.fontZoomReset"
  ]
}

Available size-related commands:

• workbench.action.zoomReset - Reset UI zoom
• workbench.action.zoomIn - Zoom in UI
• workbench.action.zoomOut - Zoom out UI
• editor.action.fontZoomReset - Reset editor font zoom
• editor.action.fontZoomIn - Increase editor font zoom
• editor.action.fontZoomOut - Decrease editor font zoom
• workbench.action.terminal.fontZoomReset - Reset terminal font zoom
• workbench.action.terminal.fontZoomIn - Increase terminal font zoom
• workbench.action.terminal.fontZoomOut - Decrease terminal font zoom

Note: When you change the preset, this array is automatically populated with the preset's default commands. Set preset to custom to manually customize this list.

resetSizes.settingsToReset

Type: array of string Default: []

Setting keys to reset (remove custom values) when Reset All Sizes is run. This removes your custom overrides from the configured scopes, restoring VS Code defaults.

{
  "resetSizes.settingsToReset": [
    "editor.fontSize",
    "editor.lineHeight",
    "terminal.integrated.fontSize",
    "window.zoomLevel"
  ]
}

Common size-related settings:

• window.zoomLevel - UI zoom level
• editor.fontSize - Editor font size
• editor.lineHeight - Editor line height
• terminal.integrated.fontSize - Terminal font size
• terminal.integrated.lineHeight - Terminal line height

Note: When you change the preset, this array is automatically populated. The zoom preset sets this to an empty array. The zoomAndSettings preset includes 5 size-related settings.

resetSizes.scopes

Type: array of string (enum: "user", "workspace", "workspaceFolder") Default: ["workspace"]

Configuration scopes to apply settings reset. Only used when settingsToReset is not empty.

{
  "resetSizes.scopes": ["workspace"]
}

• user: Reset user-level settings (Global settings)
• workspace: Reset workspace-level settings (.vscode/settings.json)
• workspaceFolder: Reset workspace folder settings (in multi-root workspaces)

resetSizes.promptBeforeReset

Type: boolean Default: true

Show confirmation dialog before removing settings. Only applies when settingsToReset is not empty.

{
  "resetSizes.promptBeforeReset": true
}

Recommended: Keep this enabled to avoid accidentally removing settings.

resetSizes.reloadAfter

Type: string (enum: "never", "prompt", "always") Default: "prompt"

When to reload window after reset:

• never: Never reload automatically
• prompt: Prompt user to reload if settings were changed
• always: Always reload immediately

{
  "resetSizes.reloadAfter": "prompt"
}

resetSizes.showSummaryNotification

Type: boolean Default: true

Show notification with summary of reset actions (number of commands executed and settings reset).

{
  "resetSizes.showSummaryNotification": true
}

Configuration Examples

Example 1: Quick zoom reset (default - "zoom" preset)

{
  "resetSizes.preset": "zoom"
}

Executes 3 zoom reset commands. No settings are modified.

Example 2: Zoom and settings reset ("zoomAndSettings" preset)

{
  "resetSizes.preset": "zoomAndSettings",
  "resetSizes.scopes": ["workspace"],
  "resetSizes.promptBeforeReset": true
}

Resets zoom commands AND removes 5 size-related settings from workspace configuration.

Example 3: Reset everything across all scopes

{
  "resetSizes.preset": "zoomAndSettings",
  "resetSizes.scopes": ["user", "workspace", "workspaceFolder"],
  "resetSizes.promptBeforeReset": true,
  "resetSizes.reloadAfter": "always"
}

Comprehensive reset: resets zooms and removes settings from all scopes, then reloads immediately.

Example 4: Custom command list

{
  "resetSizes.preset": "custom",
  "resetSizes.commands": [
    "workbench.action.zoomReset",
    "editor.action.fontZoomIn"
  ],
  "resetSizes.settingsToReset": [
    "editor.fontSize",
    "workbench.colorTheme"
  ]
}

Fully customized: reset UI zoom, increase editor font, and reset fontSize + theme settings.

Example 5: Only reset specific settings, no commands

{
  "resetSizes.preset": "custom",
  "resetSizes.commands": [],
  "resetSizes.settingsToReset": [
    "terminal.integrated.fontSize"
  ]
}

No commands executed, only removes terminal fontSize override.

Multi-Root Workspaces

In multi-root workspaces, when workspaceFolder scope is selected, the extension will apply setting resets to all workspace folders by default.

Known Limitations

1. Other Open Windows: Cannot force-reset zoom in other open VS Code windows unless window.zoomPerWindow is disabled (zoom is global).

2. Settings Require Reload: Some setting changes require a window reload to take full effect. The extension prompts for reload when appropriate.

3. Remote Environments: In remote development scenarios (Remote SSH, WSL, Dev Containers), some settings may have restrictions on writability.

4. Terminal May Not Exist: The terminal font zoom reset may fail gracefully if no terminal is currently open. This is expected behavior and not an error.

5. Confirmation Dialog: The settings reset confirmation (when enabled) is a modal dialog that will block the UI until user responds.

Output Channel

The extension logs detailed information to the "Reset Sizes" output channel. To view:

1. Open Output panel (View > Output or Ctrl+Shift+U)
2. Select "Reset Sizes" from the dropdown

This is useful for debugging or understanding what the extension did.
