Trunk comparison: Hyundai i10 vs Skoda Fabia

Key Differences
The Skoda Fabia offers significantly more loading length: with the seats folded down, its trunk is +9.1 in (19%) longer than the Hyundai i10, and with the front seats upright, even +10.6 in (57%) longer.
The width of the trunk at its narrowest point is +3.9 in (11%) greater in the Hyundai i10, while the width of the trunk opening is +3.9 in (11%) larger in the Skoda Fabia.
All other measured values (height of the trunk opening, trunk depth +0.4 in/6%, loading edge height +0.8 in/3%) are below the 10% threshold or equal.
Impact on Usability
More loading length in the Fabia practically means: significantly better transport capability for long items (e.g., boards, skis, furniture parts) and overall more usable trunk volume with the seats folded down. Those who frequently transport long or bulky items clearly benefit from the Fabia.
The greater narrowest interior width in the i10 makes it advantageous for bulky but relatively narrow loads that need to pass through tight spots in the trunk.
In contrast, the larger trunk opening in the Fabia makes it easier to lift wide items in and out — wide parts can be loaded more easily in the Fabia, whereas they are more likely to hit the opening in the i10.
The slightly greater depth in the Fabia (+0.4 in) and the somewhat higher loading edge in the i10 (+0.8 in) are only marginally relevant: the depth hardly changes the volume, and the 2-cm difference in loading edge height only minimally increases the effort to lift heavy items.
In summary: For longer or bulkier transports, the Skoda Fabia is the more practical choice; for transports through narrower interior cross-sections, the Hyundai i10 can offer advantages, albeit with a somewhat less favorable loading opening.
