Trunk comparison: Seat Ibiza vs Skoda Kamiq

Key Differences
The width of the Škoda Kamiq's trunk opening is 5.5 in (16%) larger than that of the SEAT Ibiza. This makes loading wider or bulkier items significantly easier and reduces the risk of bumping while storing or having to angle furniture pieces.
The depth of the trunk (loading edge to trunk floor) of the SEAT Ibiza is 1.2 in (19%) greater than that of the Škoda Kamiq. This means the trunk floor of the Ibiza sits lower below the loading edge.
Implications for Usability
The larger opening width of the Kamiq makes it easier to load and unload wide items (e.g., large boxes, wide suitcases, parts of furniture). Loading bulky items is also more practical because less maneuvering is needed.
Combined with the slightly larger length dimensions of the Kamiq (approximately 9% longer with seats folded down and upright), this results in a more practical loading opening for wide or flat cargo.
The deeper trunk floor in the Ibiza offers somewhat more "depth volume" below the loading edge, which can be advantageous when storing taller or stackable items.
At the same time, the greater distance between the loading edge and trunk floor requires more lifting effort when placing heavy items inside, as they must be lifted over a higher edge. This can make loading and unloading more strenuous, especially with heavy loads.
All other differences from the comparison (length differences with seats folded or upright each +6–4.7 in, opening height +0.8 in, loading edge height +0.4 in, narrowest width equal) are minor (<10%) and only moderately affect everyday use.
Summary
Those who frequently transport wide, bulky items or prefer a comfortable loading opening are better served by the Škoda Kamiq. Those seeking a bit more depth volume in the trunk and willing to accept a slightly higher lift when loading will find advantages with the SEAT Ibiza.
