Deer vs Elk

Elk and deer are close relatives, but elk are far larger. A bull elk stands about 4.5 to 5 feet at the shoulder and weighs 700 to 1,000 pounds, while an average white-tailed buck is about 32 to 34 inches at the shoulder and around 140 pounds. Virginia wildlife officials describe elk as roughly five times the size of a white-tailed deer.

The color pattern is the second cue. An elk has a tan rump patch, black legs and a dark brown mane, while a white-tailed deer has uniform leg color, a white throat patch and a big white tail that shows when it runs. This page compares the white-tailed deer, the most common deer, with the elk.

When you are looking at which

Deer

• The animal is about waist-high on an adult, roughly 32 to 34 inches at the shoulder, with a white throat patch.
• You see a big fluffy white tail flash as it runs.
• The antlers curve forward from the head with tines pointing up.
• All four legs are the same color as the body.

Elk

• The animal is huge, around 4.5 to 5 feet at the shoulder.
• You see a tan rump patch and dark brown mane on the neck.
• The antlers sweep back over the shoulders and can reach nearly 5 feet across.
• The legs look black against a lighter body.

How this works

The quiz asks about shoulder height, rump and tail, antler direction, leg color and neck. They come from state wildlife agency guidance on telling elk from white-tailed deer, including notes written for hunters, and each answer is matched to a measurement or marking those agencies give.

It is built for white-tailed deer and elk, the pair most often confused in the eastern and central US. Mule deer, moose and other deer species differ, and young animals are smaller. If you must be certain, for hunting or for reporting, check with your state wildlife agency.
