Goldendoodles come in various sizes, typically classified into miniature, medium, and standard categories.

• Miniature Goldendoodles usually weigh between 15 to 30 pounds and stand about 13 to 15 inches tall at the shoulder.
• Medium Goldendoodles generally weigh between 30 to 45 pounds and stand about 15 to 20 inches tall.
• Standard Goldendoodles are the largest and typically weigh between 45 to 90 pounds and stand about 20 to 24 inches tall at the shoulder.

These sizes affect their living space needs and exercise requirements. Also, the full growth period can last just over a year, with some dogs taking up to two years to fully mature. Size can vary based on genetics and breeding decisions.
