Data validation question:How do I change the font size on the drop down list?

I've validated my cells from a drop down list and now I can't read the drop down value. My data validation population list are very small fonts. How do I change the font size on the drop down list?

You would change the size of the font and the cells containing the drop down and not the named ranged you used.

I have done that when I pick the drop down the name fonts are real small and then when you populate the cell the names show up at the right font size. But I am unable to read the fonts in the drop down because it is so small. I even change the font in the list and the cell I am populating?
