Trunk comparison: Skoda Karoq vs Skoda Octavia Wagon

Key Differences
Škoda Octavia Wagon offers significantly more cargo length: +11.8 in (19%) with seats folded down and even +13 in (43%) with the first row upright compared to the Karoq. These are the largest relative differences in the comparison.
Škoda Karoq has a higher trunk opening and greater "depth": the opening is +5.5 in (18%) higher and the depth (loading edge to trunk floor) is +2 in (50%) larger than in the Octavia. These values are also significant.
The other dimensions differ only slightly: loading edge height above the road (+1.6 in / 6%), narrowest trunk width (+0.4 in / 1%), and opening width (+0.4 in / 1%) — these are practical minor differences.
Impact on Usability
The longer cargo areas of the Octavia Wagon (especially with the rear seats upright) make it clearly better suited for longer items like slats, long boxes, skis, or furniture parts. Those who frequently transport long items or need maximum cargo length clearly benefit from the Octavia.
The Karoq is advantageous when height and volume in the vertical direction matter: the higher trunk opening makes it easier to load tall items through, and the greater depth behind the loading edge offers more space for bulky, bulky, or tall cargo.
However, the loading edge is slightly higher, which can minimally complicate lifting very heavy items.
In short: for long cargo, Octavia Wagon; for taller or bulky/awkward cargo, Karoq. Width differences are negligible and hardly affect everyday practicality.
