Set Chart Height and Width to Match Page Dimensions

[sam314159]

I am using the following code to set a chart's height and width:

[vba]
ActiveSheet.ChartObjects (1)
With ActiveChart.Parent
.Height = 524.2
.Width = 623
.Top = topStartLocation
.Left = leftStartLocation
End With
[/vba]

That works great on my machine but it looks bad on other machines. Is there any way to change:

.Height = 524.2

to

.Height = pageHeight?

[VBA].Height = (ThisWorkbook.Sheets("1").UsedRange.Rows.Count + 2) * 7[/VBA]
