However, the Goldendoodle tends to come in three different sizes: Miniature, Small Standard, and Large Standard. The Miniature Goldendoodle is the result of a Miniature or Toy Poodle crossed with a Golden Retriever. These dogs tend to range in size from 13 to 20 inches in height and 15 to 35 pounds in weight. The average height for a Small Standard Goldendoodle is 17 to 20 inches; the weight is 40 to 50 pounds. The Large Standard Goldendoodle averages 20 to 24 inches in height and weighs 50 to 90 pounds.
