xterm menu font size

How can I increase the size of xterm menu font? i.e. as presented when I hold Ctrl and left mouse click the xterm window.

I've noticed the same in xpaint, tiny menu font that is difficult to see easily.

Thanks. When I installed/set things up I didn't create a .Xresources but did create a .Xdefaults and I dropped something similar into there (different choice of font) and its working great. Thanks again.

For xpaint I've created a launch script with a choice of font that works well for me

xpaint -menufont "Liberation-14:matrix=0.85 0 0 0.9"
