There are a few things you can do to make your toolbar buttons larger in Excel. One way is to go into the File menu, and then choose Options. From here, select the Advanced tab and scroll down to the Display section. Here, you can change the User Interface options to make your toolbar buttons larger. Another way to change the size of your toolbar buttons is to hold down the Ctrl key while scrolling up or down with your mouse wheel. This will make your toolbar buttons larger or smaller, depending on which way you scroll.
If you want even more control over the size of your toolbar buttons, you can use a registry hack. First, open the Run dialog box by pressing Windows key + R. Then, type in
"regedit", and press Enter key. Next, navigate to the following key:
[HKEY_CURRENT_USER\Control Panel\Desktop] "LogPixels"=dword:00000060
Here, you'll see a value called
"LogPixels". This value controls the size of all fonts and icons in Windows. By default, it is set to 96 DPI (dots per inch). If you want larger toolbar buttons, you can change this value to 120 DPI. To do this, simply double-click on the
"LogPixels" value and change the Value data: field to
"120". Once you've done this, click on the OK button and restart your computer for the changes to take effect.
