Custom scrollbar width

NOTE: This help page only applies to Chromium-based browser (Google Chrome, Microsoft Edge, Opera) users.

Custom Scrollbars offers three preset values for the width of your scrollbar: wide, thin and hidden. However, Chromium-based browsers support setting a custom measurement for the width of your scrollbar.

Support measurement units

Below is a list of the measurement units that the Custom Scrollbars browser extension supports and what they mean:

• cm - Centimeters
• em - Unit relative to the font size of the element
• in - Inches
• mm - Millimeters
• pt - Points
• px - Pixels
• rem - Unit relative to the font size of the page root
• vw - Percentage of browser window width

NOTE: To prevent users from making the add-on settings page inaccessible by accidentally setting a scrollbar width that's too large, the width of the scrollbar on the Custom Scrollbars settings page will not appear larger than 50% of the page.

Custom widths in Firefox

Custom widths are currently not available in Firefox due to a limitation in the W3C CSS Scrollbars Module Level 1 standard that Firefox is using. This functionality will be added to the Custom Scrollbars add-on when Firefox supports this feature.
