Read-only.

If the control is a window, this refers to its current interior size: i.e., not counting titlebar, statusbar, borders, etc. If it's maximized, this will be the true size of the window interior, as opposed to `size` which is the interior size once this window is no longer maximized.

If this control is a pane and [can-scroll](https://ref.dm-lang.org/skin/param/can-scroll.md) is true, this is the size of the display area not including the scrollbars.
