Quick tip on width. A deers ear is about 8 inches. If you have an ears length outside on both sides that's about 16 inches. The width between ear tip to ear tip varies with position of the ears and the deer itself. Anywhere from 18 to 23 inches.
Be conservative and less likely looking like a fool, pick 18 plus 8 plus 8 equals 34.
One side doesn't quite look 8. Sooooooo. 33 ish. And when you tape it and it's 34 or 35, you can be pleasantly surprised.
