What is average antler size for Idaho bull elk?

April 5, 2026

Quick Answer

Idaho bull elk average antler size varies, but a commonly cited range is 6-8 points, with some bulls reaching up to 10 or more points and weighing around 300-400 inches ( Boone and Crockett Club measurement).

Understanding Idaho OTC Elk Habitat

Idaho offers numerous over-the-counter (OTC) elk hunting opportunities, particularly in the western and central parts of the state. Elk in these areas tend to inhabit mountainous terrain, often between 5,000-9,000 feet in elevation. To find bulls with impressive antler size, focus on areas with abundant forage, such as meadows and ridges with willow, aspen, and grasses.

Hunting Idaho OTC Elk: Tips and Techniques

To increase your chances of harvesting a large bull during Idaho’s OTC elk season, it’s crucial to be prepared and adapt to the terrain and weather conditions. Bring binoculars to scan the landscape from a distance, as this will help you locate and assess the antler size of nearby bulls. When tracking elk, use the “scent wall” method to identify areas where elk are likely to be feeding and bedding. This involves following a wall of elk scent, often marked by droppings and tracks, which can lead you to a nearby bull.

Antler Size and Age Correlation

While antler size can vary greatly among Idaho bull elk, there is a general correlation between age and antler size. Bulls in their prime, typically 5-10 years old, tend to have larger antlers. However, this is not a hard and fast rule, as some younger bulls may grow impressive antlers due to access to quality habitat and genetics. When evaluating a bull’s antlers, consider the number of points, as well as the overall size and symmetry of the rack. This will help you determine whether the bull is an older, more mature animal or a younger bull with potential for growth.
