Compact SUVs are generally larger than small SUVs. The body length of small SUVs ranges between 3580mm to 4350mm, with a wheelbase exceeding 2670mm. Compact SUVs typically have a body length ranging from 4300mm to 4750mm, with a wheelbase around 2600-2760mm. SUV size classifications are as follows: Small: length ≤4200mm, wheelbase ≤2620mm; Compact: 4200mm≤ length ≤4600mm, 2620mm≤ wheelbase ≤2700mm; Mid-size: 4600mm≤ length ≤4800mm, 2700mm≤ wheelbase ≤2800mm; Full-size: 4800≤ length ≤5000mm, 2800mm≤ wheelbase ≤2950mm; Full-size: length ≥5000mm, wheelbase ≥2950mm.

As a veteran driver who frequently goes on long-distance hauls, let me share some insights. Compact SUVs definitely offer more space than small SUVs, which is related to the vehicle class. Compact SUVs are generally over 4.5 meters in length with a longer wheelbase, allowing three adults to sit comfortably in the back without cramped legs, and the trunk can easily fit three or four suitcases plus some miscellaneous items. Small SUVs, on the other hand, are typically around 4.3 meters long. The rear seats are fine for two people, but three will have their shoulders pressed together. As for the trunk, it's usually full after fitting two carry-on suitcases. However, small SUVs have an advantage in urban areas—they're easier to park and navigate through narrow alleys, whereas the larger body of compact SUVs can sometimes be cumbersome. If you often travel with the whole family or need to carry cargo, going straight for a compact SUV is more practical.

I often help friends with car buying advice, so here are my thoughts. From a spatial perspective, compact SUVs are generally more spacious, especially in terms of headroom and legroom, which are noticeably larger. Last time I accompanied a friend on a test drive, sitting upright in the back seat of a small SUV almost touched the roof, while a compact SUV still had more than a fist's worth of space left. The difference in trunk depth is even more significant—a compact SUV can fit a folded bicycle, while a small SUV's trunk can only hold a few shopping bags. Of course, space utilization is also key. For example, the Honda XR-V, a small SUV with its clever magic seat design, can match the cargo capacity of a compact SUV when the rear seats are folded down. However, if you have strict space requirements, such as needing to install a child seat or pet carrier, a compact SUV is still the more comfortable choice.

I usually enjoy researching real-world test data of different car models, so let me briefly explain the differences. According to automotive classification standards, compact SUVs typically have a wheelbase of over 2,670mm, while subcompact SUVs usually stay below 2,600mm. This wheelbase difference directly affects rear legroom, with compact SUVs generally offering over 100mm more space. The cargo capacity gap is even more pronounced - typical compact SUVs provide 500-600 liters of standard trunk space, whereas subcompact SUVs average around 400 liters. However, some modern subcompact SUVs like the Volkswagen T-Roc cleverly maximize space through short overhang designs, with rear seating that rivals certain compact models. Generally speaking, if space is your priority, you can't go wrong with a compact SUV, but subcompact SUVs regain some ground with superior maneuverability.
