Mazda CX-30 vs CX-3 Dimensions: A Complete Size Comparison Guide

When we compare compact crossovers, size matters more than many people realize. It affects comfort, practicality, parking ease, and even driving feel. That’s exactly why the debate between the Mazda CX-30 and Mazda CX-3 keeps popping up among drivers looking for a stylish small SUV.

At first glance, these two vehicles look similar—sleek curves, sporty stance, and that unmistakable Mazda DNA. But beneath the surface, the dimensions tell a very different story.

Think of it like comparing two backpacks. They may look alike on the outside, but once you start packing them, the difference becomes obvious.

In this guide, we’ll break down Mazda CX-30 vs CX-3 dimensions in detail—covering length, width, height, wheelbase, interior space, cargo capacity, and real-world practicality. By the end, we’ll know which one truly offers more space and which one suits different lifestyles.

Let’s dive in.

Understanding the Mazda CX-30 and Mazda CX-3

Before analyzing measurements, it helps to understand where these two vehicles sit in Mazda’s lineup.

Mazda CX-3: The Subcompact Pioneer

The Mazda CX-3 arrived earlier as Mazda’s entry-level crossover. It’s based on the Mazda2 platform and focuses heavily on urban agility and compact size.

Key characteristics include:

• Small footprint for easy city driving
• Sporty handling
• Limited interior and cargo space
• Lower overall height and width

It’s essentially the smallest SUV in Mazda’s range.

Mazda CX-30: The New Middle Ground

The Mazda CX-30 came later and fills the gap between the Mazda CX-3 and the Mazda CX-5.

It’s built on the same platform as the Mazda3, which means:

• Larger dimensions
• More interior space
• Wider stance
• Better passenger comfort

In simple terms, the CX-30 is like the older sibling who grew a few inches taller and got a bigger backpack.

Quick Dimension Comparison Overview

Before diving deeper, let’s look at the basic dimension differences.

Right away we can see the CX-30 is bigger in nearly every category.

But numbers alone don’t tell the full story. Let’s break each dimension down.

Exterior Dimensions Breakdown

Exterior size determines how the vehicle behaves in real life—from tight parking spaces to highway stability.

Vehicle Length

Mazda CX-3 Length

The CX-3 measures roughly 4,275 mm (168.3 inches) in length.

This compact length provides:

• Easier parallel parking
• Better maneuverability in tight streets
• A smaller turning circle

It’s a great match for city drivers.

Mazda CX-30 Length

The CX-30 stretches to about 4,395 mm (173 inches).

That’s about 120 mm longer than the CX-3.

This extra length improves:

• Cabin legroom
• Cargo capacity
• Road stability

In everyday terms, the CX-30 feels a bit more planted and spacious.

Vehicle Width

Width plays a big role in interior comfort.

Mazda CX-3 Width

The CX-3 measures about 1,765 mm (69.5 inches) wide.

While compact, this can make the rear seats feel slightly tight when three passengers sit side-by-side.

Mazda CX-30 Width

The CX-30 is roughly 1,795 mm (70.7 inches) wide.

That extra 30 mm might not sound huge, but it noticeably improves:

• Shoulder room
• Seating comfort
• Cabin openness

It’s like switching from economy class to premium economy on a flight—subtle but meaningful.

Vehicle Height

Height affects both headroom and driving position.

Mazda CX-3 Height

The CX-3 stands around 1,535 mm (60.4 inches) tall.

This slightly lower profile helps give it a sportier feel.

Mazda CX-30 Height

The CX-30 comes in at about 1,540 mm (60.6 inches).

The difference is minimal, but the CX-30 benefits from:

• Slightly better visibility
• Improved headroom
• More SUV-like seating posture

Wheelbase Comparison

The wheelbase—distance between the front and rear wheels—directly affects interior space.

Mazda CX-3 Wheelbase

The CX-3 uses a 2,570 mm wheelbase.

This shorter wheelbase contributes to:

• Quicker turning
• Agile driving
• Limited rear legroom

Mazda CX-30 Wheelbase

The CX-30 stretches to 2,655 mm.

That extra 85 mm gives the CX-30:

• More rear passenger space
• Better ride comfort
• Greater highway stability

In simple terms, the CX-30 rides like a longer, calmer cruiser.

Ground Clearance Comparison

Ground clearance matters if you drive over rough roads or speed bumps.

Mazda CX-3 Ground Clearance

Typical clearance: 155–160 mm

This works well for urban driving but isn’t ideal for rough terrain.

Mazda CX-30 Ground Clearance

Typical clearance: 175 mm

That extra height gives the CX-30:

• Better visibility
• Slight off-road capability
• Confidence over uneven roads

Interior Dimensions: Passenger Space

Exterior size doesn’t always translate directly to interior comfort. Let’s look inside.

Front Seat Space

Both vehicles provide comfortable space for driver and passenger.

However, the CX-30 offers:

• Wider seats
• Slightly more shoulder room
• Better elbow space

The difference isn’t dramatic, but it’s noticeable during long trips.

Rear Legroom

Rear legroom is where the CX-30 really pulls ahead.

Approximate figures:

• CX-3 rear legroom: ~35 inches
• CX-30 rear legroom: ~36.3 inches

That may sound small, but passengers quickly feel the difference.

The CX-3’s rear seats are best suited for:

• Children
• Short trips

The CX-30 can comfortably handle adult passengers.

Rear Headroom

Headroom differences are subtle but present.

The CX-30’s slightly taller cabin gives passengers:

• Better head clearance
• A less cramped feeling

Tall passengers will likely prefer the CX-30.

Cargo Space Comparison

Cargo capacity is often the deciding factor when choosing a compact SUV.

Mazda CX-3 Boot Space

With the seats up, the CX-3 offers roughly 264 liters (9.3 cubic feet) of cargo space.

This fits:

• Grocery bags
• Small luggage
• Daily errands

But packing for a long trip can be challenging.

Mazda CX-30 Boot Space

The CX-30 significantly improves cargo capacity.

Boot space: 430 liters (15.2 cubic feet).

That’s nearly double the usable cargo volume compared to the CX-3.

You can comfortably fit:

• Multiple suitcases
• Baby strollers
• Weekend travel gear

Cargo Space With Seats Folded

When the rear seats are folded:

CX-3

• Around 1,260 liters

CX-30
