Trunk comparison: Kia Ceed vs Renault Clio

Key Differences
The most noticeable differences concern cargo length, trunk depth, and loading edge height. The Kia Ceed offers 8.7 in (17%) more cargo length with folded seats and 3.1 in (11%) more with the front seats upright than the Renault Clio.
The depth between the loading edge and trunk floor is significantly greater in the Clio: +26 in (600%) in favor of the Clio.
Additionally, the loading edge of the Kia Ceed sits 16.5 in (175%) higher above the ground than that of the Clio. Smaller differences such as opening height (+0.4 in) or minimal width differences (+0.8 in) are negligible; the width of the trunk opening is the same.
Impact on Usability
More cargo length in the Kia Ceed means specifically: longer items like skis, long boxes, or slim furniture pieces can be more easily accommodated crosswise or lengthwise. Even with folded seats, the Ceed is better suited for longer loads.
The Renault Clio scores with its significantly greater depth and lower loading edge. Due to the deep cargo floor, tall or bulkier items can be set further "down," increasing the usable interior height. The lower loading edge makes lifting heavy loads easier and reduces lifting effort during loading and unloading.
In practice, this means: for long, flat items and longer loads, the Kia Ceed is the more practical choice; for frequent handling of heavy items or bulky or tall loads that benefit from a deep cargo floor, the Renault Clio is better suited.
Since the opening width is the same and other dimensions differ only slightly, the actual everyday usability is mainly determined by length (Ceed) versus depth and lower loading edge (Clio).
