What is the roof rack limit on a Subaru Forester?
The roof rack limit on a Subaru Forester is 150 pounds (68 kilograms), including the weight of the rack itself, crossbars, and any cargo. This is the maximum total load the roof can safely support. This article explains what that rating means, how to stay within it, and practical loading tips for Forester owners.
Official roof load limit
Subaru’s owner manuals and official specifications consistently list a maximum roof load of 150 lb (68 kg) for Forester models equipped with a roof rack. This rating covers the entire roof system — rails, crossbars, and any cargo or accessories mounted on the roof — and is the upper bound you should not exceed during loading.
Before loading your Forester’s roof, review the components that contribute to the limit and plan accordingly. The following list outlines what counts toward the rating and how to interpret it.
- Cargo carried on the roof, including bags, boxes, and any roof-mounted cargo box or basket
- Weight of the roof rack components themselves (crossbars, rails, and mounting hardware) that bear the load
- Any additional roof-mounted accessories or gear attached to the rack
- The total weight of everything on the roof must not exceed 150 lb (68 kg)
By understanding what contributes to the limit, you can plan loads that stay within the safe range and avoid overloading the roof.
How to stay within the limit
To ensure you remain under the 150 lb ceiling, follow these practical loading guidelines. The list below helps you quantify and manage roof loads effectively.
- Weigh your cargo before loading. If possible, use a luggage scale or weigh items individually and sum the total to ensure you stay under the limit
- Distribute weight evenly across front and rear crossbars to avoid concentrating heavy items at one point
- Keep the center of gravity low by placing heavier items toward the bottom of the load and as close to the roof as possible
- Avoid tall, bulky items or irregular shapes that catch wind and increase drag
- Secure all items with reliable straps and retighten after driving a short distance to account for shifts
- Remember that the 150 lb limit includes the rack and any accessories; if you don’t need the rack for a trip, remove it to reduce weight
Following these steps helps ensure your Forester remains stable, safe, and within its official roof load rating.
Dynamic versus static loading considerations
The 150 lb rating is typically described as a static load limit—the maximum weight the roof can support when stationary. Driving with a loaded roof introduces dynamic forces from wind, acceleration, braking, and road conditions, which reduce the margin for safety. In practice, drivers should plan lighter loads and maintain generous margins, especially on long trips or at highway speeds.
Practical tips for dynamic loading
When traveling with a roof load, reduce risk by planning lighter cargo, checking fastenings regularly, and adapting driving style (slower speeds, smoother steering) to compensate for the added wind uplift and handling changes.
Summary
The Subaru Forester’s official roof load limit is 150 pounds (68 kg), including the weight of the roof rack and cargo. Always plan loads carefully, distribute weight evenly, and account for dynamic forces while driving. For model-year-specific variations or if you use aftermarket racks, consult your owner's manual or Subaru’s official guidance to confirm the exact rating for your vehicle.
