Then either change to a theme that has the sizes you prefer
- or change the pixel size of the upper border in the theme you're currently using.
- or change the resolution of the screen to something smaller.
- Or ..... switch to Enlightenment (E26 currently).
If you're looking to switch themes check this thread:
