Curiously Android doesn't offer a way to fiddle with it directly but most Android devices have a simple text file that declares the pixel density and simply by modifying it you get larger (or smaller, if you want) fonts and other UI elements. It's a pretty neat feature and baffles me why it isn't given pride of place in the settings somewhere, since developers have to basically account for all different densities anyway.
