Trunk comparison: Opel Grandland vs Skoda Fabia

Biggest Differences (Highlighted)
In terms of cargo space, the Opel Grandland is significantly longer: with the rear seats folded down, the Grandland's trunk is 11 in (20%) longer than the Škoda Fabia's, and with the front seats upright, it is 5.9 in (20%) longer.
The Škoda Fabia, on the other hand, offers a greater trunk depth: the depth (loading edge to trunk floor) is 1.2 in (19%) higher than in the Grandland. Additionally, the loading edge of the Opel Grandland is 3.9 in (15%) higher above the ground than that of the Fabia.
Impact on Usability
The significantly greater loading length of the Grandland makes it more practical for long items such as slats, skis, or furniture parts and increases usable cargo capacity especially with folded seats.
The greater depth of the Fabia means more vertical cargo space directly behind the loading edge, which is advantageous when transporting tall or stacked items.
The higher loading edge of the Grandland makes lifting heavy items in more difficult and can make loading bulky, low wagons or frequent loading and unloading less convenient.
Width and opening differences (each +3.1 in for the Grandland and +0.4 in for the Fabia's opening) are under 10% and thus less significant, but slightly improve handling of bulky cargo in favor of the Grandland.
Overall, the Grandland is the better choice when long items or more cargo volume with folded seats are needed; the Fabia scores when a bit more depth directly behind the loading edge and lower loading height are desired.
