How wide are the crossbars on a Subaru Outback?
Crossbars on a Subaru Outback do not have a single universal width; they come in different sizes depending on model year and whether you use Subaru’s factory roof rack or aftermarket bars. In practice, most crossbars are about a couple of inches across in cross-section.
What 'width' means in roof racks
When people talk about crossbar width, they may refer to the cross-section of the bar (its height and width) or the distance the crossbars span along the roof between mount points. Both measurements affect accessory fit and aerodynamics.
Cross-section vs span
The cross-section refers to how tall and how thick the bar is; the span or length is how long the bar is from end to end. Both figures appear in product specs and determine what attachments you can mount and how much cargo you can carry.
Dimensions you’re likely to encounter: OEM and aftermarket
This section provides typical size ranges you’ll see in official Subaru parts and common aftermarket bars. Always check the exact specs for your year and product.
- Cross-section (height × width): OEM Subaru crossbars typically present a rectangular profile around 25–32 mm tall and 38–50 mm wide. Aftermarket bars vary widely, but common rectangular cross-sections fall roughly in the same ballpark (about 25–32 mm tall by 40–60 mm wide).
- Bar length: For many Outback setups, factory crossbars are 53 inches (about 135 cm) long, though aftermarket options range from roughly 47 to 60 inches (120 to 152 cm). The length affects capacity and fitment with roof accessories.
Concluding: The exact width and length depend on whether you use OEM or aftermarket bars and the model year, so always check the product page or dealer specs for the precise measurements.
How to measure and verify compatibility
To ensure you’re selecting the right crossbars for your Outback and accessories, follow these steps.
- Measure cross-section: with a caliper or ruler, measure the height (top to bottom) and width (side to side) of one crossbar.
- Check bar length: measure from one end to the other to confirm it matches your roof rails and intended cargo space.
- Confirm load rating: ensure the system’s maximum load rating suits your cargo and that you’re within the car’s overall roof load limit.
- Verify accessory compatibility: ensure clamps or feet match the crossbar shape and the accessory’s mounting system (clamp-on, T-slot, etc.).
- Consider aerodynamics and noise: larger cross-sections can increase wind resistance and cabin noise.
Concluding: verifying dimensions, load ratings, and compatibility will ensure safe, quiet, and functional use of your roof rack.
Summary
In short, Subaru Outback crossbars vary by year and product line, but most cross-section dimensions fall in roughly 25–32 mm tall and 38–50 mm wide, with common OEM bars around 53 inches long. Always confirm exact measurements from Subaru’s catalogs or retailer specs, and measure your own bars if needed to guarantee a proper fit with your cargo and accessories.
