function GetWebSizes ($StartWeb)
{
$web = Get-SPWeb $StartWeb
[long]$total = 0
$total += GetWebSize -Web $web
$total += GetSubWebSizes -Web $web
$totalInMb = ($total/1024)/1024
$totalInMb = “{0:N2}” -f $totalInMb
$totalInGb = (($total/1024)/1024)/1024
$totalInGb = “{0:N2}” -f $totalInGb
write-host “Total size of all sites below” $StartWeb “is” $total “Bytes,”
write-host “which is” $totalInMb “MB or” $totalInGb “GB”
$web.Dispose()
}

function GetWebSize ($Web)
{
[long]$subtotal = 0
foreach ($folder in $Web.Folders)
{
$subtotal += GetFolderSize -Folder $folder
}
write-host “Site” $Web.Title “is” $subtotal “KB”
return $subtotal
}

function GetSubWebSizes ($Web)
{
[long]$subtotal = 0
foreach ($subweb in $Web.GetSubwebsForCurrentUser())
{
[long]$webtotal = 0
foreach ($folder in $subweb.Folders)
{
$webtotal += GetFolderSize -Folder $folder
}
write-host “Site” $subweb.Title “is” $webtotal “Bytes”
$subtotal += $webtotal
$subtotal += GetSubWebSizes -Web $subweb
}
return $subtotal
}

function GetFolderSize ($Folder)
{
[long]$folderSize = 0
foreach ($file in $Folder.Files)
{
$folderSize += $file.Length;
}
foreach ($fd in $Folder.SubFolders)
{
$folderSize += GetFolderSize -Folder $fd
}
return $folderSize
}

Once you have run the script, you can call it with the following PowerShell command:

GetWebSizes -StartWeb <StartURL>
