Mounting a skate deck usually calls for the standard 7/8" or 1" hardware. Some longboards and retro cruiser boards can have more or thicker plies, which means longer hardware may be needed to accommodate such variation (use 1 1/8”-1 1/4” hardware to be safe). If you plan on setting up your skateboard with risers you will need some longer bolts. An easy rule of thumb on most skate decks is to add 1" to your riser size to determine the correct hardware size (add 1 ¼” to your riser size on thicker boards). Some math skills required.

Skateboard risers give extra clearance between your deck and wheels to reduce wheel bite. Risers are usually recommended for larger wheels 55mm and above, and while not necessary for smaller skate wheels, 1/8" shock pads can always be used to help reduce vibration and stress cracks to your board. The more you progress, the more you can fine tune your setup to decide what is right for your personal skating style.
