Yes, the Alfa Romeo Spider (939) fits comfortably into a standard residential garage. Typical garages measure about 2400 mm (94.5 inches) in width and 4800 mm (189 inches) in length. With a width of 1830 mm (72 inches) not counting mirrors, and 4393 mm (173 inches) long, the Spider leaves sufficient clearance for easy parking and door opening, especially if side mirrors are folded. Its relatively low height of 1318 mm (51.9 inches) also means ample vertical clearance inside most garages.

Compared to its predecessor, the Alfa Romeo Spider (916), the 939 generation is slightly larger in overall length and width. The 939 Spider measures 4393 mm long and 1830 mm wide, while the 916 typically measures around 4220 mm in length and 1765 mm in width. This size increase gives the 939 a more modern presence and greater cabin space. The design has also evolved from the classic rounded 916 lines to a sharper, more aggressive look with Italian styling cues emphasizing aerodynamics and sporty elegance. Technologically, the 939 offers more advanced safety and comfort features, making it a more contemporary convertible sports car.

The Alfa Romeo Spider (939) is competitive in size and weight when compared to similar sporty cabriolets like the BMW Z4 (E85), Audi TT Roadster (8J), and Mazda MX-5 (NC). At 4393 mm in length and a curb weight range of 1490 to 1765 kg, it tends to be a bit larger and heavier than the Mazda MX-5, which is lighter and more compact, but comparable to the heavier and similarly sized BMW Z4 and Audi TT Roadster. The Spider’s wider stance at 1830 mm also suggests a focus on stability and sporty handling. This places it in the mid-to-upper size and weight category among its peers.

The dimensions of the Alfa Romeo Spider (939) such as its width of 1830 mm (72 inches) and relatively low height of 1318 mm (51.9 inches) contribute significantly to its handling characteristics. A wide track enhances cornering stability, while a low height reduces the center of gravity, improving agility and road-holding. Its moderate length of 4393 mm (173 inches) balances stability with maneuverability, making the Spider nimble in urban settings as well as stable on highways or twisty roads. The curb weight also plays a role—while somewhat heavier than lightweight roadsters, it enhances traction and ride quality.

While the exterior measures 1830 mm (72 inches) in width, the interior cabin space of the Alfa Romeo Spider (939) is designed to comfortably accommodate two passengers, reflecting its two-seat sports car nature. The low height of 1318 mm (51.9 inches) contributes to a sporty driver seating position but means limited headroom for taller occupants. The interior is compact yet ergonomically designed for driver engagement, typical of sporty convertibles where the focus is more on driving experience than spaciousness. Storage and passenger comfort are appropriate for short trips or weekend drives.

The Alfa Romeo Spider (939)'s dimensions of 4393 mm length and 1830 mm width combined with a low height of 1318 mm are designed to optimize aerodynamic efficiency, especially important for a convertible where the open top can affect airflow. The sharp Italian styling reduces drag and wind turbulence around the cabin when the roof is up, enhancing high-speed stability and fuel efficiency. When the top is down, aerodynamic aids help minimize buffeting and wind noise, improving comfort. Its wider stance and relatively low profile support aerodynamic balance, contributing to its sporty performance identity.
