Hi Zygy,
The default size is in the Excel 'Normal' style setting.
Format=>Style=>Modify=>Font
If you're looking to only change the apperance of some cells
rather than the default select the cells, row or column and
you can use Format=>Cells=>Font
You may also want to use the link below to the MS Excel discussion groups
for more details and options.

Will someone please enlighten me on how to reduce/change the size of typed
characters in OS Win.XPPro Office 2003 on Excel worksheets.<<

Please let us know if this has helped,
