Window: scrollMaxY property

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

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

Value

A number.

Examples

js
// Scroll to the bottom of the page
let maxY = window.scrollMaxY;

window.scrollTo(0, maxY);

Notes

Do not use this property to get the total document height, which is not equivalent to window.innerHeight + window.scrollMaxY, because window.innerHeight includes the width of any visible horizontal scrollbar, thus the result would exceed the total document height by the width of any visible horizontal scrollbar. Instead use document.body.scrollHeight. See also window.scrollMaxX and window.scrollTo.
