Determining the size of a bear's skull — what measurements matter?

Key Measurements for Trophy Bears

When evaluating the size of a bear’s skull, it’s essential to consider the width of the skull at its widest point, which is typically just below the eyes. This measurement is crucial in determining the bear’s overall size and strength. In general, a wider skull indicates a larger bear. For example, a black bear with a skull width of 14 inches or more is typically considered a large animal.

Lower Jawbone and Skull Length

The length of the lower jawbone and the overall skull length from the back of the ear to the tip of the nose are also critical measurements. In grizzly bears, a lower jawbone length of 6 inches or more is generally considered large, while in brown bears, a skull length of 23 inches or more suggests a large animal. These measurements, combined with the skull width, can help hunters and taxidermists accurately determine the size and strength of a bear.

Evaluating Skull Damage and Wear

It’s also essential to evaluate the skull for damage and wear, as these can affect its overall size and shape. Look for signs of breakage, cracks, or other damage that may have occurred during the bear’s lifetime or after death. Additionally, consider the age of the bear, as older animals may have worn-down teeth and a more weathered appearance. By carefully considering these factors, hunters can make an accurate assessment of a bear’s size and trophy value.
