All purebred dog breeds have standards and it’s likely your dog will fall within those standards for both weight and size.  To find out dog standards, visit the American Kennel Club, they have information on over 150  recognized breeds.

Here’s what the AKC says about my favorite breed, the Pembroke Welsh Corgi:

Size, Proportion, Substance
Height (from ground to highest point on withers) should be 10 to 12 inches. Weight is in proportion to size, not exceeding 30 pounds for dogs and 28 pounds for bitches. In show condition, the preferred medium- sized dog of correct bone and substance will weigh approximately 27 pounds, with bitches approximately 25 pounds. Obvious oversized specimens and diminutive toylike individuals must be very severely penalized. Proportions–Moderately long and low. The distance from the withers to the base of the tail should be approximately 40 percent greater than the distance from the withers to the ground. Substance–Should not be so low and heavy-boned as to appear coarse or overdone, nor so light-boned as to appear racy.

Estimating the size of a mixed breed dog isn’t quite so easy as it is for a purebred dog.

How Big Will My Puppy Get If It’s a Mixed Breed?

If you happen to know the size of both the dam (mother) and sire (father) then you can reasonably estimate the puppy will end up.  The puppy will be  either the size of the dam, the sire or somewhere in the middle.  Generally female puppies will end up with an adult weight similar to their dam and male puppies will reach a size similar to their sire but really determining the size of a mixed breed dog is a guess.
