Reading Width

Different screens benefit from different line lengths. This setting lets you choose a comfortable default maximum width for the reading area (as a percentage of viewport width).

Where to configure

Set in hugo.toml at your site root:

[params.theme]
  # Note: Default max reading width (vw = % of viewport width).
  # Range: number between 60 and 92.
  # Example: 80 means the content area is at most 80% wide.
  defaultReaderWidthValue = 80

Notes

• Clamped range: the theme clamps the value to 60%–92% for better readability across screens.
• Responsive: on narrow screens (e.g. phones), this setting is ignored so content can use the full width.

Priority rules

1. User adjustment: the width chosen via the settings panel is stored locally.
2. Site config: for new visitors, defaultReaderWidthValue is used.
