Window: scrollMaxX property

{{APIRef}} {{Non-standard_header}}

The Window.scrollMaxX read-only property returns the maximum number of pixels that the document can be scrolled horizontally.

Value

A number.

Examples

// Scroll to right edge of the page
let maxX = window.scrollMaxX;

window.scrollTo(maxX, 0);

Notes

Do not use this property to get the total document width, which is not equivalent to window.innerWidth + window.scrollMaxX, because {{domxref("window.innerWidth")}} includes the width of any visible vertical scrollbar, thus the result would exceed the total document width by the width of any visible vertical scrollbar. Instead use {{domxref("element.scrollWidth","document.body.scrollWidth")}}. See also {{domxref("window.scrollMaxY")}}.
