The height of the Audi S4 Avant (B9) ranges from 1411 mm to 1437 mm (55.6 to 56.5 inches), a dimension that balances aerodynamic design with interior space. Despite the relatively low roofline compared to SUVs, the Avant body style offers sufficient headroom for most passengers, particularly in the front and rear seats. The slightly variable height depends on configuration and suspension settings. This careful design ensures that occupants benefit from a comfortable seating position while the car retains a sporty, streamlined silhouette.

The Audi S4 Avant (B9) measures 1842 mm (72.5 inches) in width without mirrors, but this expands to 2022 mm (79.6 inches) when the mirrors are opened. This wider footprint when mirrors are out is important to consider for parking in tight spaces or narrow garages. While the car fits standard garage widths easily when mirrors are folded, drivers need to be mindful of the mirrors in confined areas to avoid collisions or scrapes. The foldable mirrors allow for easier maneuvering and parking in such tight environments.
