Trunk comparison: Ford Focus Wagon vs Toyota Corolla Wagon

Key Differences
Among the two wagon models, two significantly different dimensions stand out: The depth of the trunk (distance from loading edge to trunk floor) is considerably larger in the Toyota Corolla Touring Sports (+2.4 in / +300%).
In contrast, the smallest width in the trunk is significantly larger in the Ford Focus Wagon (+7.1 in / +19%). All other measured values are only in the single-digit percentage range and thus hardly noticeable.
What are the implications for usability?
The much greater trunk depth in the Toyota means more usable volume in the lower area of the cargo space: bulky, tall items can be recessed deeper, or items can be placed further forward without protruding over the loading edge.
This is practical if you often have bulky or tall cargo that needs to be recessed into the footwell. At the same time, a deeper surface can make lifting and sliding very heavy loads somewhat uncomfortable because more lift to the floor is required.
The greater narrowest width in the Ford makes it more flexible in everyday use for wide items: wide boxes, strollers, sports equipment, or furniture parts are more likely to fit crosswise without problems.
This width is especially beneficial for irregularly shaped or bulky loads that would otherwise cause issues at narrow points in the trunk. The slightly larger opening width of the Ford (only +2 in / 5%) is present but less noticeable.
In summary: If you frequently transport very wide cargo, the Ford Focus Wagon is more practical. If you need more volume in the lower area and a deeper loading floor (e.g., for tall/bulky items that should be recessed), the Toyota Corolla Touring Sports has the advantage.
Smaller differences in overall length, opening height, and loading edge height are marginal and hardly affect everyday usability.
