Signiture Image Dimensions

I have created the image below but couldn't find what size images in signitures had to be. i will be happy to resize it if it is too big. Could someone please tell me the required dimensions.

It's 300 x 60, however I think it maybe distracting.

point taken, i'll slow down the animation

Yeah very distracting. Maybe make it animate less (or not at all).

Size of max signature:
