Hi there,
Thanks for writing. Unfortunately not a way to resize it at this time and it's unfortunately depending on the screen density. The signature field type only stores 160x160 pixels so it's really pretty low res, and even scaled up several times to what you see there now, otherwise it would be a tiny little box!
If I made it scale larger the quality differential when you reload would be pretty pronounced.
