' changes the column width to mmWidth
Dim w As Single
    If ColNo < 1 Or ColNo > 255 Then Exit Sub
    Application.ScreenUpdating = False
    w = Application.CentimetersToPoints(mmWidth / 10)
    While Columns(ColNo + 1).Left - Columns(ColNo).Left - 0.1 > w
        Columns(ColNo).ColumnWidth = Columns(ColNo).ColumnWidth - 0.1
    Wend
    While Columns(ColNo + 1).Left - Columns(ColNo).Left + 0.1 < w
        Columns(ColNo).ColumnWidth = Columns(ColNo).ColumnWidth + 0.1
    Wend
End Sub

Sub SetRowHeightMM(RowNo As Long, mmHeight As Integer)
' changes the row height to mmHeight
    If RowNo < 1 Or RowNo > 65536 Then Exit Sub
    Rows(RowNo).RowHeight = Application.CentimetersToPoints(mmHeight / 10)
End Sub

This example macro shows how you can set the row height for row 3 and the column width for column C to 3.5 cm:

Sub ChangeWidthAndHeight()
    SetColumnWidthMM 3, 35
    SetRowHeightMM 3, 35
