Arcade machines come in various sizes and form factors, each designed to enhance the gaming experience. The most common cabinet sizes include:

1. Upright Cabinets: Typically 60-75 inches tall, 24-30 inches wide, and 30-36 inches deep. These are the classic stand-up arcade units seen in arcades.

2. Cocktail Cabinets: Compact and table-style, usually 30-36 inches tall, 24-30 inches wide, and 24-30 inches deep, allowing multiplayer gameplay from opposite sides.

3. Cabaret/Min Cabinets: Smaller than uprights, around 50-60 inches tall and 20-24 inches wide, often used for space-saving setups.

4. Showcase Cabinets: Large and immersive, standing 70-80 inches tall with wide screens, designed for deluxe arcade experiences.

Form factors vary based on game type and space constraints, with upright and cocktail being the most popular. Understanding these dimensions helps in designing or selecting the perfect arcade setup for home or commercial use.
