# bounds var (client)

Source: https://ref.dm-lang.org/client/var/bounds
Added in BYOND 509.

(Also `bound_x`, `bound_y`, `bound_width`, and `bound_height`.)

The read-only bounds var returns the map coordinates, in pixels, covered by the client's viewport when accounting for pixel offsets, eye, step, etc. (The coordinates are only relevant to the default `client.dir` value of `NORTH`, and the `TOPDOWN_MAP` or `SIDE_MAP` map formats.)

If the viewport is not currently on the map (for instance, when the eye is at a null location), the var reads as null. Otherwise, it is a list with five values (x, y, width, height, z) in the same form used by the bounds proc.

The alias vars bound_x, bound_y, bound_width, and bound_height can also be used to retrieve the individual values from the list. They too will be null if the viewport is not on the map.
