i have a spreadsheet that is zoomed to 90%. this is then accessed
through a vb app which opens it at 100%, and so is to big.

how can i reduce the width / height by a proportion of 1/9th for all
rows / colums in a selected range?

Why not just set the zoom back to 90%

ActiveWindow.Zoom = 90

the application that opens the spreadsheet 'sees' the spreadsheet at
100% zoom, so unfortunatley need to resize rows and colums..

Although I am not sure what you mean by 'sees',


loop through the columns and reduce the columnwidth by 1/9. loop through
the rows and reduce the rowheight by 1/9.

if that is what you want. (maybe you meant multiply by .9). You might need
to adjust the font size as well.

yep, exactly, loop through rows and colums in selection and reduce
height / width by 1/9th.

many thanks.

perhaps you thought i was ok with the logic, but unfortunately i cannot
write the code!!
if someone could post the necessary code please!

Sub ABEF()
For Each col In ActiveSheet.UsedRange.Columns
w = col.ColumnWidth
w = (8 / 9) * w
col.ColumnWidth = w
Next
For Each rw In ActiveSheet.UsedRange.Rows
h = rw.RowHeight
h = (8 / 9) * h
rw.RowHeight = h
Next
End Sub

Of course this would assume the aspect ratio is 1, which it isn't, so you
might need to reduce rows less than columns I think.

Hi,
i wrote some code below.
this macro converts size simply. but actual size is rounded in pixels.
so, total height and width might be different from expected.

Sub Test()
ZoomRange Selection, 9 / 10, 9 / 10
End Sub

Sub ZoomRange(target_range As Range, px As Double, py As Double)
Dim cw() As Double, rh() As Double
Dim w1 As Double, w2 As Double, tmp As Double
Dim i As Long
Dim r As Range

Set r = target_range.Areas(1)
On Error Resume Next
Application.EnableEvents = False
r.Worksheet.Activate
r.Select
Application.EnableEvents = True

On Error GoTo ErrorHandler
If MsgBox("Macro is changing size of cells. You cannot undo. Continue?", _
vbOKCancel Or vbExclamation) < vbOK Then Exit Sub

Application.ScreenUpdating = False

'for conversion from points to number of characters
With r.Columns(1)
tmp = .ColumnWidth
.ColumnWidth = 1: w1 = .Width
.ColumnWidth = 2: w2 = .Width
.ColumnWidth = tmp
End With

ReDim cw(1 To r.Columns.Count)
ReDim rh(1 To r.Rows.Count)

For i = 1 To UBound(cw)
tmp = r.Columns(i).Width * px
If tmp w1 Then
cw(i) = (tmp - w1) / (w2 - w1) + 1
Else
cw(i) = tmp / w1
End If
If cw(i) 256 Then
MsgBox "Column width too large.", vbExclamation
Exit Sub
End If
Next
For i = 1 To UBound(rh)
rh(i) = r.Rows(i).Height * py
If rh(i) 409 Then
MsgBox "Row height too large.", vbExclamation
Exit Sub
End If
Next

'set columnwidth
For i = 1 To UBound(cw)
r.Columns(i).ColumnWidth = cw(i)
Next
'set rowheight
For i = 1 To UBound(rh)
r.Rows(i).RowHeight = rh(i)
Next

Application.ScreenUpdating = True
Exit Sub

ErrorHandler:
MsgBox Error(Err), vbExclamation
Exit Sub
End Sub

many thanks tom and oakaizawa.
you have probably saved me 2 days work with your code (the workbook had
dozens of sheets)
i really dont know whether google groups should make me this happy, but
it has!!
