What are the dimensions of the back of a Subaru Outback?
Recent Subaru Outback models offer about 32.5 cubic feet of cargo space behind the rear seats, expanding to roughly 75.7 cubic feet with the rear seats folded. Exact linear measurements—length, width and height of the cargo bay—vary by model year and trim.
The question concerns the physical dimensions of the back section of the vehicle, not just how much it can hold in terms of volume. Because interior space changes with redesigns and seating configurations, this article covers what can be measured, notes typical ranges, and explains how to obtain precise figures for a specific year and trim.
Current-generation cargo space and capacity
The following figures describe how much cargo can fit, which is often the most practical metric for planning trips or storage.
- Cargo space behind the rear seats: 32.5 cubic feet
- Cargo space with rear seats folded: 75.7 cubic feet
These numbers reflect the typical maximum behind the second row for recent Outbacks. Actual usable space can vary slightly with options like a full-height cargo shelf, underfloor storage, or the presence of a spare tire in certain configurations.
Physical dimensions: length, width and height
Subaru does not publish a single, standard interior length, width and height measurement for the cargo bay that applies across all years. Instead, the company reports cargo volume. If you need precise linear dimensions for a particular model year (for example, to fit a specific item through the tailgate), you should consult the official brochure or measure the opening and cargo bay in person.
How to measure the cargo bay
To determine the actual interior dimensions, you can measure three key points: (1) load-floor length from the tailgate opening to the back of the folded or upright rear seat; (2) width at the floor between the wheel wells; (3) loading height from the floor to the ceiling or cargo cover. Repeat measurements with the rear seats in different configurations if your use case varies.
Year-specific data and how to get it
Because the Outback has undergone redesigns and trim changes, the exact L x W x H for the cargo bay can differ year by year. If you tell me the model year (and whether you plan to keep the rear seats up or folded), I can pull the precise interior dimensions from Subaru’s official specs or reputable brochures.
Summary
In short, the Subaru Outback’s back area provides about 32.5 cubic feet of space with the rear seats up and about 75.7 cubic feet with them folded, with linear dimensions that vary by year and configuration. For exact measurements, identify the model year and configuration, then consult the official Subaru brochure or measure directly.
What can fit in the back of a Subaru Outback?
A camp stove, hiking gear, tents, ice chests, fishing poles - all can be packed into the back of your Subaru Outback. Naturally, all Outback models come standard with roof rails for kayaks, skis, and surfboards so your big outdoor toys can stay out of the way on top.
Will a full size mattress fit in the back of a Subaru Outback?
No, a standard full-size mattress (53 inches wide) cannot fit completely inside a Subaru Outback because the narrowest part of the interior is approximately 42 inches, according to this Facebook post. However, it is possible to fit certain types of full-size mattresses, such as foam or inflatable ones, by folding the seats, with the hatch partially or fully open, and securing the mattress to the roof rack with straps.
Fitting a full-size mattress
- Foam or inflatable: You can fit a full-size foam or inflatable mattress inside if the seats are folded down and the hatch is open, but the mattress will likely overhang the rear.
- Securing the mattress: To make it drivable, you must securely strap the mattress to the roof rack, using the doors to pass the straps through if necessary.
- Safety precautions: Drive slowly, keep to back roads, and be sure to flag the overhanging portion of the mattress as required by law.
Alternative options
- Trimmed mattress: Consider trimming a larger foam mattress to better fit the interior space, as shown in this Facebook post.
- Twin mattress: A twin mattress (around 38 inches wide) will fit easily inside with room to spare for other items, as noted in this Baldwin Subaru blog post.
- Custom mattress: You can also get a custom-sized mattress designed specifically for the Outback to maximize the available space, according to Mattress Insider.
