Start by measuring the bat from the end of the knob to the top of the barrel. Then compare that measurement with the usable interior dimensions listed on the product page. Decide whether the bat will be displayed by itself or alongside a baseball, and whether you prefer a horizontal presentation that shows the bat's full length or a vertical case that uses less wall width.
Protection also varies by model. Enclosed cases help limit dust, fingerprints, and unnecessary handling, while open wall mounts create a simpler presentation with easier access. UV-resistant panels help reduce light exposure, but no display should be placed in direct sunlight.
