Always Open at 100% Zoom

Written by Allen Wyatt (last updated August 11, 2022)
This tip applies to Excel 2007, 2010, 2013, 2016, 2019, and Excel in Microsoft 365


If you work with workbooks first worked on by your colleagues, you may be frustrated by the zoom factor applied to those workbooks by those others. For instance, if your colleague (Wanda) has a huge monitor, it wouldn't be uncommon for her to reduce the Excel's zoom factor to 75% or even 60%. The purpose, of course, is so she isn't overpowered by things that look very large at the full zoom factor.

The problem is that the zoom factor is saved with the workbook. Thus, when Wanda saves the workbook and hands it off to you, when you open it, the workbook is still displayed at whatever zoom factor Wanda last used. If you don't have the same size monitor as Wanda, then the workbook may be almost illegible on your system.

There are only two possible solutions to this problem. First, you can simply adjust the zoom factor once you open the workbook. There are a multitude of ways to do this, but the easiest involves using the Zoom control at the right side of the status bar. You can click the centerpoint on the Zoom slider and quickly get back to 100%, or you can click the percentage beside the slider to display the Zoom dialog box.

The second workaround is to create a macro that gets saved with the workbook. The macro can run every time the workbook is opened, and thereby set the zoom factor. (This macro should be added to the This Workbook code window in the VBA editor.)

Private Sub Workbook_Open()
    ActiveWindow.Zoom = 100
End Sub

The only problem with a macro such as this, of course, is that whenever Wanda (your colleague) opens the workbook on her system, the zoom factor is also set and she'll get just as frustrated with you as you were with her.

Perhaps a solution is to create a more involved macro—one that checks the current screen resolution and then sets the zoom factor accordingly. For instance, the following macro could be used to make the adjustments based on resolution:

Declare Function GetSystemMetrics32 Lib "user32" _
    Alias "GetSystemMetrics" (ByVal nIndex As Long) As Long

Public Sub ScreenRes()
    Dim lResWidth As Long
    Dim lResHeight As Long
    Dim sRes As String

    lResWidth = GetSystemMetrics32(0)
    lResHeight = GetSystemMetrics32(1)
    sRes = lResWidth & "x" & lResHeight
    Select Case sRes
        Case Is = "800x600"
            ActiveWindow.Zoom = 75
        Case Is = "1024x768"
            ActiveWindow.Zoom = 125
        Case Else
            ActiveWindow.Zoom = 100
    End Select
End Sub

This routine checks the screen resolution and adjusts the window accordingly. Other resolutions and zooms may be added easily. To make the routine run automatically, just use a Workbook_Open event handler in the This Workbook code window to trigger the macro:

Private Sub Workbook_Open()
End Sub

You can tailor the Workbook_Open() procedure to check if you're the one opening the workbook and take all sorts of actions specifically for you. Or other actions for users who are not you.
Besides setting zoom, the macro might scroll to cell A1 on each sheet, go to a particular sheet. hide or unhide sheets, etc...
For other users, the macro might protect the workbook.

@Akhtar Hussain
To adjust Zoom for all sheets in a workbook, substitute the following in place of the Tip's Workbook_Open code:

Private Sub Workbook_Open()
    Dim Sh As Object, ASh As Object
    Set ASh = ActiveSheet
    For Each Sh In Sheets
        ActiveWindow.Zoom = 100
        '^or^ ScreenRes
    Next Sh
End Sub

Thank you J. Woolley

I have 13 worksheets in my workbook. With this code I've to run on each worksheet seperately.
Is there a way to apply code once for all 13 worksheets?

You can also read about my DisplayScreen (aka Screen) function in the article I wrote here:

2020-05-28 10:25:57

J. Woolley

The M_DisplayScreen module at accommodates a multi-monitor configuration. It has code to identify which screen displays ActiveWindow. The code uses Windows API GetSystemMetrics, GetActiveWindow, MonitorFromWindow, GetMonitorInfo, CreateDC or GetDC, and GetDeviceCaps. If you are familiar with VBA, perhaps you can adapt the code for your purpose.

Bonjour Allen,
Merci pour ces belles démonstrations. Cela m'aide beaucoup.
Dans ce cas précis de calcul du zoom maximal pour la fenêtre active, à l'évènement d'ouverture du classeur Excel, la difficulté que je rencontre est que je ne travaille jamais avec un seul écran. Cela varie de 2 à 3 écrans, chacun ayant une résolution différente (celui du PC, un écran 24" et un autre 24" de nombre de lignes et colonnes différentes).
Comment faire pour savoir sur quelle écran s'ouvre la fenêtre du classeur Excel, afin d'en ajuster le zoom non-pas à la résolution de l'écran du PC, mais de l'écran sur lequel Excel se lance ?

Merci de votre aide,

Control button + mouse wheel is what I prefer for changing zoom in Microsoft apps. The incremental changes are not a granular as the Excel slider, though.

AS well as the screen size the view is also determined by the setting of Display > Scale and layout.
How can the % that this setting is on be determined to adjust for those variances?

Alan, macros may not be your cup-of-tea but for users, like me, who frequently use them, it is easy to set the file-save default to Excel Macro-Enabled Workbook (*.xlsm). Do this is Options > Save > Save Workbooks.

Alan Cannon

The downside to the macro solution is that now the workbook must be saved as a macro enabled sheet such as xlsm.
