R: Find Size of Device Surface

dev.size {grDevices} | R Documentation

## Find Size of Device Surface

### Description

Find the dimensions of the device surface of the current device.

### Usage

    dev.size(units = c("in", "cm", "px"))

### Arguments

`units` | the units in which to return the value – inches, cm, or pixels (device units).

### Value

A two-element numeric vector giving width and height of the current device; a new device is opened if there is none, similarly to `dev.new()`.

### See Also

The size information in inches can be obtained by `par("din")`, but this provides a way to access it independent of the graphics sub-system in use. Note that `par("din")` is only updated when a new plot is started, whereas `dev.size` tracks the size as an on-screen device is resized.

### Examples

    dev.size("cm")
