Trunk comparison: Skoda Fabia vs VW Touran

Key Differences
The VW Touran offers significantly more length in the cargo area with the seats folded down than the Skoda Fabia: +15 in (27%). The length also clearly favors the Touran when the first row of seats is upright: +10.6 in (36%).
Conversely, the Skoda Fabia has a significantly longer trunk with all seats fully upright: +15.7 in (118%). The Fabia also provides a much greater depth between the loading edge and the trunk floor: +7.1 in (1800%). In terms of usable width at the narrowest point, the Touran is advantageous: +4.7 in (13%).
Impact on Usability
Due to the longer loading surface of the Touran with folded seats and in the configuration with the first row upright, the Touran is better suited for long or bulky items (e.g., furniture, long slats, spacious transports).
The greater narrow width and slightly larger opening width make storing wide or irregularly shaped cargo easier in the Touran.
The Fabia scores when all seats are upright: its significantly longer trunk in this configuration makes it more practical for normal family or shopping use with full passenger occupancy and additional luggage.
The much greater depth between the loading edge and trunk floor means more volume vertically (better stackability, more room for tall items), but combined with the slightly higher loading edge, it can make lifting heavy loads more difficult.
Smaller differences such as the opening height or width deviating by <4–5% are hardly relevant in practice. In summary: for long, wide, or flexibly usable cargo, the Touran is the more practical choice; for more usable volume with full seating and greater interior depth, the Fabia is preferable.
