Dear Isabel Burns,
Thank you for posting in Microsoft Community.
Based on your description, I understand you're hoping for some help with the issue where the font size in Excel’s drop-down lists remains too small, even when zooming in.
First, please kindly allow me to provide you some information that drop-down box in data validation is not configurable.
But according to my research and testing in my environment (as shown in the screenshot below), I’d like to share some information, and you could try:
In fact, there is no direct way for us to increase the font size of the drop-down list, but you can apply the following VBA code to change the drop-down list cells zoom setting to make the text appear larger. Please do as follows:
1. Go the worksheet which contains the drop-down list that you want to increase its font size.
2. Right click the sheet tab, and select View Code from the context menu, in the popped-out Microsoft Visual Basic for Applications window, please copy and paste the following code into the blank Module window:
VBA code: Increase drop down list font size to enlarge the cell zoom
Private Sub Worksheet_SelectionChange(ByVal Target As Range)
'updateby Extendoffice
On Error GoTo LZoom
Dim xZoom As Long
xZoom = 100
If Target.Validation.Type = xlValidateList Then xZoom = 400
LZoom:
ActiveWindow.Zoom = xZoom
End Sub
3. Then save and close this code, now, when you click the drop-down list cells, the cell’s zoom will be enlarged, and the drop-down list will be appeared larger, but, when you click other cells do not contain the drop-down list, the cell zoom will be normal.
Note: In the above code, xZoom = 400 will change the drop-down list cells zoom to be 400, you can change this zoom number to your need.
The above step still doesn't enlarge the Excel dropdown list, so you can try this alternative solution: You can use an ActiveX ComboBox instead of Data Validation
You can replace the default dropdown with a ComboBox (ActiveX Control), which allows you to customize font size, zoom level, etc.
- Go to the Developer tab > Insert > choose ComboBox (ActiveX Control)
- Draw the ComboBox on your sheet
- Right-click the ComboBox > Properties: Font.Size = 14 (or larger) ListFillRange = A1:A4 (or the range containing your list)
- Use the ComboBox1_GotFocus event to automatically zoom in if needed
If you can't see the "Developer" option, please kindly choose "File" > "Options" > "Customize Ribbon" > unable "Developer".
I hope these steps help resolve the issue. Since we are not Microsoft employees, but participants in this community, you need Microsoft to solve this problem in subsequent system updates. I suggest that you may need to submit your problem in the Feedback Center. Ideas · Community
