What is Average Size Of Mule Deer Antlers In Colorado?

April 5, 2026

Quick Answer

In Colorado, the average size of mule deer antlers varies by region and age, but overall, they tend to be relatively large, with a median main beam length of around 25-30 inches and a score range of 100-130 Boone and Crockett points.

Antler Growth Patterns

Mule deer antlers in Colorado exhibit a unique growth pattern, with the majority of their growth occurring within a relatively short period, typically from mid-summer to early fall. This is influenced by factors such as nutrition, genetics, and environmental conditions. Antler growth rates can vary, but in general, a mature buck will grow around 1-2 inches of antler per day during the peak growth phase.

Regional Variations

Antler size and shape can vary significantly across different regions in Colorado, reflecting the unique characteristics of the local deer populations. In the western part of the state, antlers tend to be larger and more complex, with a greater number of points and a longer main beam. In contrast, antlers in the eastern part of the state are generally smaller and more compact. This variation is influenced by factors such as habitat quality, food availability, and genetic diversity.

Measuring and Scoring Antlers

To accurately measure and score mule deer antlers, hunters and taxidermists use a standardized system, such as the Boone and Crockett Club’s scoring system. This involves measuring the length of the main beam, the length and number of points, and the circumference of the main beam at its widest point. By using this system, hunters and taxidermists can accurately compare and evaluate the size and quality of mule deer antlers, providing a more accurate picture of the deer’s quality and size.
