How to make LXDE menu (for Lubuntu) bigger?

I’m trying to see if there’s a way to make the Lubuntu [start] menu bigger.

For reference, I’m not referring to the LXPanel itself, but rather the menu that shows up when you click the leftmost button on the panel (i.e. NOT the menu for shut-down options).

I’ve tried tweaking with the options it has in the preferences, but nothing has helped so far.

There HAS to be a way to just be able to resize the menu in a way that makes it cover more than it’s oddly small height and width. Even if the menu just shows a bunch of links, that size it too small.

As someone who treats usability with utmost importance, this is a considerable pet-peeve for me.

To make it clearer:

I want to be able to configure not only the menu’s height & width, but it’s padding and margins as well.

Isn’t there a file I can just play around with?
