When you first start up Microsoft Access, and create a new query, the font size may be too small for you.
In order to increase the font size, click File, select Options, select the Object Designers tab, and in the Query design section change the Size to the desired number. After you click OK, the changes won’t take effect for any open queries. Close and Re-open the query to see the changes.
