Almost every vehicle fitment question on this site ends the same way: the car maker publishes a volume in cubic feet, the organizer maker publishes a volume in liters, neither publishes a footprint, and the honest answer is go and measure your own car.
The Forester is the exception, and it is worth saying why before anything else. Subaru's own specification sheet publishes nine separate cargo figures for this car — not just the two volume numbers everyone quotes, but the width between the wheel housings, the load length at the floor, the cargo area height, the liftover height and the rear gate opening in both dimensions. That is enough to do real arithmetic. It is also more than most manufacturers publish about a car's interior, and it is the reason this page exists rather than a page about some other SUV.
What Subaru publishes
These are Subaru's figures for the 2026 Forester, quoted from the specification sheet and cited at the foot of this page. Note the second column carefully, because it is the part nobody mentions in a showroom.
| Dimension | Base trim | All other trims (panoramic moonroof) |
|---|---|---|
| Cargo volume, rear seatbacks up | 29.6 cu ft | 27.5 cu ft |
| Cargo volume, rear seatbacks down | 74.4 cu ft | 69.1 cu ft |
| Cargo area height | 34.9" | 32.4" |
| Cargo area width between wheel housings | 43.3" | 43.3" |
| Max load length at floor, seats up | 36.5" | 36.5" |
| Max load length at floor, seats down | 70.7" | 70.7" |
| Rear gate max opening width | 49.2" (47.5" at the lower area) | Same |
| Rear gate opening height | 32.2" | Same |
| Cargo liftover height | 28.9" (Wilderness 29.5") | Same |
Turning cubic feet into organizer units
Organizers are sold in liters and cars are described in cubic feet, which is why nobody ever connects the two. The conversion is fixed, so this is arithmetic rather than an estimate.

#1 · SUV wells and a real grocery run
FORTEM Trunk Organizer for SUV, 65L
FORTEM
Same construction as the 50 L, 30% more volume. In an SUV well the smaller one slides; this one is wide enough to wedge.
65 L is the size most SUV owners should start at. Below that the organizer becomes a thing that slides around next to your shopping rather than the thing holding it.
Volume is not the same as footprint. A tall 65 L bag in a shallow sedan well wastes the height and tips; the same bag in a Highlander well is barely half the floor.
What works
- The most common size in this category, so it is the one most vehicles are sized around
- Same rigid-plate construction as the 50 L
- Straps let you anchor it to a tie-down instead of trusting friction alone
What does not
- No published external dimensions
- 600D rather than the 1680D used on FORTEM's cooler models
- Soft cover only
Skip this if
Skip it if your trunk is a sedan's. In a sedan well the height is dead space and a 45 L two-compartment model sits better.

#2 · Checking it against your cargo well before you buy
DRIVE Auto Products Collapsible Multi-Compartment Car Organizer
DRIVE Auto Products
The only organizer on this page that publishes its external dimensions, which is the one number you need and the one number nobody else in the category states.
Every other organizer here publishes a liter figure and no footprint, which tells you how much it holds and nothing about whether it fits. 23" × 17" is a footprint you can go and mark out in your own trunk before you spend anything.
Stiff plates in every panel — not just the base — is the structural claim that decides whether the box stays square when the load shifts. A soft-walled tote folds inward and everything in it is loose again.
DRIVE sells a matching cargo net as a separate accessory for loads that stand above the rim. It is not in this box, and the listing says so.
The same organizer is listed in several colorways and they do not all publish the same detail. The gray listing is the one that states the dimensions, which is why it is the one linked here.
What works
- Publishes external dimensions — almost nothing else in the category does
- Stiff base plates in every side panel, per the listing
- Waterproof lining, which the fabric-only organizers here do not claim
- Tie-down straps anchor it to the trunk rather than trusting friction
What does not
- No published capacity in liters, so it cannot be compared to the FORTEM range on volume
- The cargo net that used to ship with some versions is now a separate purchase
- Soft cover only — it will not take weight on top
Skip this if
Skip it if you need a lid you can stack on. This is an open-topped box with straps, and a hard-lidded organizer is a different product.

#3 · Splitting one trunk into many small bays
FORTEM Car Trunk Organizer, Multi-Compartment, 65L
FORTEM
The multi-compartment layout of FORTEM's 65 L — more dividers rather than more volume, which is the right trade when your problem is loose small items, not bulk.
More compartments is the correct answer when the mess is many small things. It is the wrong answer when the mess is four grocery bags — dividers just get in the way.
Compartment count is the single most over-marketed number in this category. Two useful bays beat six that are each too narrow for a box of wipes.
What works
- Compartment-heavy layout for small-item control
- Standard FORTEM non-slip base and strap system
- Folds flat
What does not
- Dividers reduce usable volume for bulky loads
- No published external dimensions
- 600D rather than 1680D at this size
Skip this if
Skip it if what you actually carry is groceries. Buy the plain 65 L and use the collapsed single-bay mode.

#4 · Anyone who uses the trunk at the roadside after dark
Deckert Car SUV Trunk Organizer with Reflective Stripes
Deckert
Same rigid-plate, non-slip, 600D formula as the rest — with reflective stripes, which is a genuinely useful detail if you ever open your trunk on a shoulder at night.
Reflective stripes on a trunk organizer are a small thing that matters exactly once — when you are kneeling at the back of the car on a hard shoulder.
Water-resistant is not waterproof. It buys you time against a spilled bottle, not against a bag of ice.
What works
- Reflective stripes
- Rigid plates on the base AND the side panels, per the listing
- Water-resistant 600D polyester
What does not
- No published capacity or dimensions
- Less established than the FORTEM and DRIVE lines
- Reflective stripes are useless in daylight, which is when most people load a trunk
Skip this if
Skip it if the trunk only ever opens on a driveway. You are paying for a feature that never fires.

#5 · Anyone who buys frozen food before a long drive home
FORTEM Trunk Organizer with Cooler Bag, 1680D, 65L
FORTEM
The upgrade here is the fabric, not the cooler: 1680D Oxford instead of 600D. The insulated bay is the reason to buy it, the denier is the reason it lasts.
1680D is roughly three times the yarn weight of 600D. In practice that is the difference between a bag that frays at the strap anchors in a year and one that does not.
A cooler bay inside a trunk organizer is not a cooler. It buys you the drive home, not an afternoon at the beach — treat it as insulation, not refrigeration.
What works
- 1680D Oxford — the heaviest fabric FORTEM lists in this range
- Insulated bay integrated rather than a loose bag rattling around
- Three compartments plus the cooler
What does not
- The cooler bay's own capacity is not published
- Heavier and bulkier than the plain 65 L when you collapse it
- Insulated bays are the first thing to smell if a leak is not cleaned up
Skip this if
Skip it if your drive home from the store is ten minutes. You are paying for insulation you will never need and losing a compartment to it.

The footprint check, which is the one that actually decides
Volume is the wrong number and it is the only one most people look at. What decides whether an organizer works in a Forester is 43.3 inches — the published width between the wheel housings, and the narrowest point of the cargo floor.
Exactly one trunk organizer on this site publishes its external dimensions: the DRIVE organizer, at 23 inches long by 17 inches wide by 11 inches high. Because both halves of the problem are published, this particular pairing can be worked out on paper. Here it is.
The practical version, if you would rather not do arithmetic in a parking lot: one 65 L organizer against the seat backs leaves most of the floor free, and two organizers only work end-to-end across the car, never side-by-side in their wide orientation.
The rear gate is not your constraint — but its height might be
This is the genuinely non-obvious thing that falls out of Subaru's numbers, and it runs opposite to what most people assume.
The rear gate opens 49.2 inches wide at its widest and 47.5 inches at the lower area. Both are wider than the 43.3 inches between the wheel housings. So anything narrow enough to sit on the Forester's cargo floor is automatically narrow enough to go through the opening — the gate never becomes the limiting factor on width. You can stop worrying about that one.
Height is the opposite story. The gate opening is 32.2 inches tall while the Base trim's cargo area is 34.9 inches tall. The opening is 2.7 inches shorter than the space behind it. For a soft-sided organizer this is irrelevant — you squash it through. For a rigid box, a roof-box-style hard case or a loaded organizer you are trying to lift in without tipping, it is the number that decides whether the thing goes in upright or has to be angled.
On the moonroof trims the two figures converge — 32.2 inches of opening against 32.4 inches of cargo height — so on those cars, if it fits the space it will go through the hole.

Liftover height, and why a 65 L organizer is heavier than you think
Subaru publishes a cargo liftover height of 28.9 inches, rising to 29.5 inches on the Wilderness. That is low for an SUV and it is one of the quietly good things about this car.
It matters here because an organizer changes how you load. Loose shopping bags go in one at a time; an organizer is a single object you fill at the trolley and then lift over a 28.9-inch lip in one movement. A 65 L box of tins and bottles is not light. If you have a bad back, the argument for the multi-compartment layouts on this page over one big bay is not tidiness — it is that you can carry them in two trips.
A Forester holds about as much as a Model Y, and tells you far more about it
This site has one other vehicle fitment page, for the Tesla Model Y, and putting the two published figures next to each other makes a point worth making.
| Vehicle | Seats up | Seats folded | Footprint published? |
|---|---|---|---|
| Subaru Forester, Base | 29.6 cu ft | 74.4 cu ft | Yes — nine separate figures |
| Subaru Forester, moonroof trims | 27.5 cu ft | 69.1 cu ft | Yes — nine separate figures |
| Tesla Model Y, two-row | 30.2 cu ft | 72.1 cu ft | No — volume only |
Two completely different cars, within one cubic foot of each other behind the rear seats. The same 65 L advice applies to both, and for the same reason. The difference is not the space — it is that Subaru publishes the width, the depth, the height and the opening, and Tesla publishes a volume and stops. That is why this page can show its working and the Model Y page cannot.
If you are cross-shopping the two, the cargo-area conclusion is a wash. Buy on everything else.
A note on the Wilderness
The Wilderness trim differs from the rest of the range in exactly one cargo dimension that Subaru publishes: the liftover height is 29.5 inches rather than 28.9. Subaru also publishes 9.3 inches of ground clearance for the Wilderness against 8.7 inches for everything else. Those two differences are the same six tenths of an inch, which is the whole story — the car sits higher, so the load lip sits higher. Nothing about the cargo area itself has changed.
Its cargo volume figures sit in the same column as every other non-Base trim — 27.5 cubic feet with the seats up, 69.1 folded — so nothing on this page changes for a Wilderness owner except that you are lifting a loaded organizer marginally higher. Buy the same thing everyone else buys.
Seats up or seats folded changes which organizer to buy
The published load length at the floor nearly doubles when the 60/40 seatbacks go down: 36.5 inches becomes 70.7 inches. That is not a marginal difference and it should change what you buy.
- If the back seats are usually occupied, you are shopping for a 36.5-inch-deep space. One 65 L organizer against the seat backs is the right answer, and anything longer than about 30 inches will stop the hatch closing over a loaded load.
- If the seats live folded — the classic single-person Forester setup — you have 70.7 inches and the constraint disappears. Two organizers end-to-end fit comfortably, which is the case for buying a pair of smaller ones instead of one large one.
- If you switch between the two, buy for the seats-up case. An organizer sized for the folded floor is an obstruction the moment someone sits in the back.
What we cannot tell you
Whether any specific organizer other than the DRIVE fits a Forester to the inch. Eight of the nine organizers on this site publish a capacity in liters and no external dimensions at all, and we are not going to estimate a footprint from a volume — a 65 L bag can be tall and narrow or low and wide, and those behave completely differently against a 43.3-inch floor.
We also have not put any of these products in a Forester. Everything above is Subaru's published specification on one side, each maker's published specification on the other, and arithmetic in between, with the sources named.
How we picked these
Rigid base panels and securing straps were the entry requirements, as they are on every trunk organizer page here — the base is what stops the walls folding inward when the load shifts, and the strap is what stops the whole box moving. After that, sized to the published volume: 65 L is the right size for a cargo floor published at 29.6 cubic feet, with the multi-compartment layouts ranked for the liftover reason above. Every specification is the maker's own and cited on the product card, and each pick names the buyer it is wrong for.
