These five-seat SUVs share Mazda’s focus on clean design and intuitive controls, but they sit in different size classes. The useful question is not simply which is bigger—it is whether the extra 295mm of CX-5 length solves a real passenger or luggage need.

| Best fit | Town, couples and smaller families | Growing families and frequent luggage |
Why choose the CX-30?
At under 4.4 metres long, CX-30 is easier to position in multi-storey car parks and tight streets. Its 430-litre boot still handles a weekly shop, cabin case or folded pushchair, while the driving position provides an SUV-style view without making the car feel oversized.
Why move up to the CX-5?
The all-new CX-5’s gains are easiest to feel with passengers aboard. A wider rear-door opening helps access, the longer cabin provides more family room and the 583-litre boot has a lower loading lip. Fold the rear seats and Mazda quotes up to 2,019 litres, useful for bikes, DIY supplies or holiday luggage.
What changes inside?
CX-30 keeps physical controls and Mazda’s central commander interface, which some drivers value for low-distraction operation. The new CX-5 introduces a larger touchscreen with Google built-in, providing familiar Maps, Assistant and compatible apps. Try both systems while stationary: usability matters more than screen size alone.
Make the choice in one visit
- Park both cars in a typical bay and check the view at each corner.
- Sit behind your own driving position and compare rear-door access.
- Bring the pushchair, dog crate or largest regular bag.
- Compare insurance, fuel and trim equipment for the exact versions.
