Window Size in PowerShell

Question

I'm trying to set size of PowerShell window using a PowerShell script. The code I'm using is

$pshost = Get-Host

$psWindow = $pshost.UI.RawUI

$newSize =$psWindow.BufferSize

$newSize.Height = 4000
$newSize.Width = 200

$psWindow.BufferSize = $newSize

$newSize = $psWindow.WindowSize
$newSize.Height = 95
$newSize.Width = 150

$psWindow.WindowSize= $newSize

It works fine in most cases, but sometimes I get the error on certain desktop sizes. For example, I tried with 95 and failed with the error below for my desktop screen size 1440x960.

Exception setting "WindowSize": "Window cannot be taller than 82.
Parameter name: value.Height
Actual value was 95."
At line:1 char:5
+     $psWindow.WindowSize= $newSize
+     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : NotSpecified: (:) [], SetValueInvocationException
    + FullyQualifiedErrorId : ExceptionWhenSetting

Is there a way I can calculate the maximum window size setting on the machine that it is running the script on and set the size of PowerShell window?

Answer 1

Your were already on the right course.

(Get-Host).UI.RawUI.MaxWindowSize

Or more specifically:

$height = (Get-Host).UI.RawUI.MaxWindowSize.Height
$width = (Get-Host).UI.RawUI.MaxWindowSize.Width
