The same length with Surface Pro but the width is wider about 1-1.5 inch, so beware that the screen protector of Surface Pro will not fully fit Ubook Pro
idk, who would buy a screen protector of Surface Pro to cover UBook Pro anyway 
Because Ubook Pro default cover is a fingerprint magnet and I would like to have paper like cover for sketching purpose 
there will be an official CHUWI screen protector for UBook Pro, if the demand is enough for mass production.
Ubook Pro community is quite small so I doubt that they will release anything useful at this rate, however thank to the same form as Surface Pro, we can share accessories with them 
Thank you for your sharing.
its simply awesome.
