Labrador Retriever vs Golden Retriever: Size & Growth Compared
Updated October 2026
Labrador Retrievers and Golden Retrievers are almost the same size — Labs typically reach 55–80 lb and Goldens 55–75 lb, with males of both breeds at the top of those ranges. Growth timelines are nearly identical: both are large breeds that mature around 18 months. The practical difference is not size but appetite and coat — Labs are famously food-driven and gain weight easily, while Goldens carry a longer coat that hides weight changes.
