Trunk comparison: Skoda Fabia vs VW ID.3

Key Differences
The main differences concern the interior geometry of the trunk and the loading edge height. The VW ID.3 offers slightly more length with the seats folded down (+4.7 in / 9%) and is also longer with the first row of seats upright (+2 in / 7%).
The narrowest width in the trunk is also somewhat larger in the ID.3 (+3.1 in / 9%), while the width of the trunk opening is slightly greater in the Škoda Fabia (+1.6 in / 4%). The height of the trunk opening is slightly larger in the Fabia (+2.8 in / 9%).
Two values stand out clearly: the depth of the Fabia's trunk (loading edge to trunk floor) is 1.2 in or 19% greater, and the loading edge of the ID.3 is 3.5 in or 13% higher above the ground.
Impact on Usability
The 19% greater trunk depth in the Fabia means more vertical space behind the loading edge: higher cargo volume in depth and better room for bulky or taller items that should not be laid flat.
Together with the slightly larger trunk opening, this makes the Fabia more practical when frequently transporting tall or bulky cargo.
The 13% higher loading edge of the ID.3 means that lifting heavy items during loading and unloading requires more effort — this is a clear disadvantage compared to the lower Fabia when regularly transporting heavy loads.
Conversely, the ID.3 benefits from its slightly longer loading floor (with seats folded) and the somewhat larger narrow width: elongated items or those that need to lie in depth can be accommodated more easily in the ID.3.
In summary: Those who often need to lift heavy or tall items and secure them safely in the trunk have advantages with the Škoda Fabia due to the greater depth and lower loading edge.
Those who prefer elongated cargo or slightly more usable length find slight advantages in the VW ID.3 — most of the other differences are under 10% and less noticeable in everyday use.
