The Mazda GLC has 30 cu ft of cargo space. In practice that is 5 checked suitcases, or 15 carry-ons, or about 24 supermarket bags. A folded pushchair fits. Against 334 cars with a similar-sized cabin it sits above the average of 16 cu ft.
What actually fits in a GLC
Cubic feet are an abstraction. Here is the same number in things people actually load, with a packing allowance — a boot is not a cube, and corners go to waste.
| What you are loading | How many fit | Each item |
|---|---|---|
| Checked suitcases | 5 | 27 × 21 × 14″ — 4.6 cu ft |
| Carry-on cases | 15 | 22 × 14 × 9″ — 1.6 cu ft |
| Supermarket bags | 24 | about 1 cu ft each |
| Golf bags | 4 | full set, about 5 cu ft |
| Folded pushchair | Fits | about 6 cu ft |
Counts assume 80% usable volume: luggage does not tessellate, and a wheel arch eats the rest.
Cabin or boot — where the space went
Every car is a fixed envelope, and designers decide how to split it between people and things. The share below is the honest way to compare an estate with a coupé of the same footprint.
| Space | Volume | Share of total |
|---|---|---|
| Passenger cabin | 86 cu ft | |
| Cargo area | 30 cu ft | |
| Total interior | 116 cu ft |
A quarter or more given to luggage — this car is built to carry things.
Against cars with a similar cabin
Compared with 334 models whose passenger space is within eight cubic feet — a fairer group than marketing classes, which put an estate and a coupé in the same bracket.
| Measure | This car | Similar cars | Difference |
|---|---|---|---|
| Cargo volume | 30 cu ft | 16 cu ft | +14.0 cu ft |
| In checked suitcases | 5 | 2 | +3 |
Cars with the same room
Closest matches by cargo volume — useful when the boot is the deciding factor and the badge is not.
Boot 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

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. We assume 80% usable volume, because a boot is not a cube: wheel arches, a sloping tailgate and the shape of the cases themselves waste the rest. Suitcase sizes are the airline standards — 22 × 14 × 9″ for carry-on, 27 × 21 × 14″ for checked. Numbers are deliberately conservative; if we say four cases fit, four cases fit.
