I'm actually not afraid of printing things larger than a few square inches on the bed.... Waited way too long for this. Tightening up the eccentric screws on the bed carriage so it doesn't wobble also helps.
I used to print on glass, until I nearly cut a finger off.
Make sure you're using glass that can either handle the thermal cycling (that is not anything you can find at a Home Depot), or is tempered so it won't have giant sharp shards when it does finally break due to the heating -> cooling -> heating -> cooling cycles of 3d printing.
Mine did that in my hands, and the shards it broke into were sharp enough to cut down to the bone on two of my fingers, requiring a hospital trip.
....I use textured PEI now, which probably won't try to remove any digits.
