You can change windows display of message boxes and that should change the fonts in the chrome bars.

This is for windows 8.1 but should be close to the same in Win 7 or 10.

Shut down chrome.

Right click on your screen and go to personalize. Or go to control panel -> Appearance and Personalization

Go to display.

Go to change only the text size and in drop down pick Message boxes.

Pick your font size and whether you want bold.

Apply

Restart Chrome and it should be showing the new font.
