Just make sure you are looking at a walking track and not a running track. All running tracks appear much larger than walking tracks and distort the size of the deer that made them. Tracks will also tell you the direction of travel, and with a little detective work, the approximate time of travel. Tracks that point away from a known bedding area were probably made in the afternoon or evening and vice versa. This chart offers a size comparison for the front hoof of deer of both sexes and different ages.
Large bucks make large tracks.
This track was definitely made by a mature buck. When walking on even ground a doe's back hooves will tend to fall right on top of her front hooves or slightly outside of them due to the fact that her chest is narrower than her hindquarters. However, since a mature buck tends to have a wider chest than hindquarters, his rear tracks will usually fall to the inside of his front tracks. They will often fall well short of his front tracks and be toed out slightly, as well. I was in a hunting camp the other day when the new load of clients showed up.
