Trunk comparison: Kia Ceed vs VW Tiguan Allspace

Key Differences
The VW Tiguan Allspace offers significantly more length with the seats folded down: +14.2 in (≈23%) compared to the Kia Ceed.
Even with the first row of seats upright, the Tiguan is longer by +13 in (≈42%). In contrast, the Kia Ceed has a larger trunk length with all seats fully upright: +12.6 in (≈68%) compared to the Tiguan.
Furthermore, the trunk depth (loading edge to trunk floor) is significantly greater in the Kia Ceed: +4.3 in (≈1000%). The loading edge of the VW Tiguan Allspace sits higher above the road: +4.3 in (≈17%).
Finally, the trunk opening width is larger on the Tiguan: +5.5 in (≈14%). (Other differences such as opening height +1.2 in / 4% or narrow point width +1.2 in / 3% are minor.)
Impact on Usability
For long and bulky cargo, especially when seats are folded down, the Tiguan Allspace is the more practical choice: the greater length in folded configuration and the wider trunk opening make loading long items (e.g., furniture parts, skis, building materials) easier.
The Tiguan also remains clearly advantageous in certain seating configurations (first row upright).
The Kia Ceed scores when all seats are in use or when frequently traveling with a full passenger load: it offers more usable trunk length in this setup.
The greater trunk depth and lower loading edge also make the Ceed more practical for heavy or bulky luggage placed close to the loading edge — loading and unloading is less strenuous and there is more usable interior space beneath the opening.
The higher loading edge of the Tiguan means more lifting effort when loading but often provides higher ground clearance overall. The wider opening of the Tiguan facilitates passing through wider items, while smaller width differences (≈3–4%) are hardly noticeable.
Conclusion: Tiguan Allspace = better for long, bulky cargo and flexible folding configurations. Kia Ceed = advantageous with full seating occupancy, for heavy/bulky luggage, and easier loading due to lower loading edge and greater trunk depth.
