The average car offers 15.4 cu ft of trunk space — about 2 checked suitcases, measured across 518 cars. Fold the rear seats and the picture changes entirely: on the 135 models where the load bay is measured, it reaches 46 cu ft.
What actually fits
A translation from cubic feet into luggage, on the cars we measure, so the numbers below mean something.

| 9 cu ft | 1 | 4 | 7 | yes |
| 16 cu ft | 2 | 8 | 12 | yes |

A typical sedan sits near 15.4 cu ft — the average across 518 measured cars — while the roomiest hatchback or wagon offers 46 cu ft behind its rear seats.
The roomiest cars we measure
By trunk volume with the seats up — the figure carmakers quote for a sedan. Note how many are wagons and full-size sedans from before the SUV era: a trunk built into the body beats one carved out above the rear axle.

Trunk space is one number. Buying is a longer list.
- Check a VIN for recalls, complaints and its exact build
- Exact value for that car, adjusted for its mileage
- The original window sticker and factory options
- Full research report as a PDF you can hand to a mechanic
- No ads, on every page
- No ads, no tracking — and much more
How we count
Cargo and passenger volumes come from EPA interior-volume records — the same figures manufacturers file for the window sticker, measured to a standard method rather than claimed in a brochure.
The luggage counts are ours — computed for every one of the 618 models here. We assume 80% usable volume, because a trunk is not a cube: wheel arches, a sloping tailgate and the shape of the cases themselves waste the rest, so the 15.4 cu ft average becomes 12.3 cu ft you can actually pack. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked, and the roomiest car we measure swallows 8 checked cases. Numbers are deliberately conservative; if we say four cases fit, four cases fit.
Frequently asked questions
How much cargo space does a car need?
For a family of four on a week's vacation, roughly 15 cu ft — about three checked cases. Weekly shopping needs 5. The average car we measure offers —.
How many suitcases fit in a typical trunk?
A sedan at 15 cu ft takes about two checked cases; a mid-size SUV at 30 takes five; a full-size wagon past 40 takes seven. Counts assume 80% usable volume.
Do SUVs really have more space than wagons?
Often less than people assume. A trunk built into a long body beats one carved out above the rear axle — several of the roomiest cars in our data are wagons and full-size sedans, not SUVs.
Are these figures with the seats up or down?
Seats up — the volume behind the rear bench, which is how EPA records it and how you would actually load the car with passengers aboard.
