When you insert a comment into a worksheet cell, Excel places the user's name on the first line of the comment balloon in bold type. The insertion point is then at the beginning of the next line, ready for your to type. What you type is inserted, by default, in 8-point Tahoma.
If you want a larger font used for your comment, you can change the character formatting of anything within the comment itself. Just select the text, then use the controls on the Formatting toolbar or by choosing Comment from the Format menu.
Excel does not provide a way for you to change the default font specifications for comment balloons, across the board. You can change them individually (as already mentioned), but not universally within Excel. You can make a change in Windows that will affect the comment font, however. Follow these general instructions:
Figure 1. The Appearance tab of the Display Properties dialog box.
Figure 2. The Advanced Appearance dialog box.
In case you didn't figure it out from these steps, the font used in the comment balloons of Excel is determined by the ToolTip font used by Windows. Changing the ToolTip font changes the comment balloons, but it also changes things in other applications besides Excel, as well. (Of course, if you think the font is too small in the comment balloons, you also probably think the font is too small everywhere else the ToolTip font is used.)
If you prefer to not change the ToolTip font, you can create an Excel macro that will step through all the comments in a worksheet to make changes.
Sub FixComments() Dim cmt As Comment For Each cmt In ActiveSheet.Comments With cmt.Shape.TextFrame.Characters.Font .Name = "Arial" .Size = 12 End With Next cmt End Sub
This macro changes the font to 12-point Arial for all comments. You could easily change the font and font size by making a change to the appropriate two lines of the macro.
