Pachinko machines are furniture-scale objects, not shelf toys. Exact dimensions vary by era and cabinet, so the only safe planning number is the measurement of the machine you are actually buying.
Measure the cabinet and the service envelope
Record width, height and maximum depth, then measure how far doors, trays or rear panels need to open. Add clearance for your hands, cords and ball return. A machine that technically fits a niche can still be impossible to service there.
Weight affects more than shipping
The stand, shelf and wall anchoring need to support the real load, and the center of gravity changes when a door swings open. Do not use a light console table just because the machine footprint fits on top.
Ask sellers for packed dimensions too
Carriers charge based on packed weight and dimensional size, not the bare cabinet. Crating, foam, corner protection and a pallet can change the shipping class significantly.
Plan the route into your home
Measure doorways, stairs, elevator openings and tight turns before delivery day. A heavy machine is much less amusing when it reaches the building but cannot reach the game room.
Use the display-space planner and shipping planner with seller-supplied measurements.
