The various differences between a gopher and a woodchuck can be noticed when you compare their size, weight, certain physical features of the two animals, and their activities. In terms of size, woodchucks are bigger than gophers since they are usually around 16 to 20 inches in length, whereas gophers are approximately 5 to 7 inches in length. It is a no-brainer that this will also affect their weight.
For this reason, woodchucks weigh more than gophers. Depending on their size, woodchucks have a weight of 4 to 6 pounds. Although, both are usually classified as pests, however, woodchucks are very good at digging holes, whereas gophers can't surpass woodchucks when it comes to gnawing.
Both woodchucks and gophers look very similar in that their eyes are small, but the front teeth of woodchucks are not as big as that of gophers. Another difference is that gophers don't reproduce in the same proportion as woodchucks.
