It is not possible for me to know for certain the size a pup will be.  I give you the true size of the parents, and you will have to go from there.  I DO NOT GUARANTEE SIZE.  THE SIZE OF A PUP IS BASED STRICTLY ON THE SIZE OF THE PARENTS AND THEIR HISTORY. THE WEIGHT OF THE PUP IS ALSO A CONSIDERATION AFTER CAREFUL OBSERVANCE OF THE PUPPY'S GROWTH.
