Trunk comparison: Dacia Duster vs Kia Sportage

Key Differences
The Dacia Duster offers two clear advantages: The height of the trunk opening is +3.1 in (11%) higher than the Kia Sportage, and the depth of the trunk (loading edge to trunk floor) is even +3.1 in (700%) higher.
These two differences are the only ones exceeding 10% and thus represent the most practically noticeable differences when loading and storing.
Impact on Usability
The larger trunk opening of the Duster makes it easier to load tall items (e.g., tall boxes, rolling containers, or bulky suitcases) because more vertical clearance is available and less tilting is necessary.
The significantly greater depth (loading edge to floor) increases the usable interior volume in terms of depth or stacking capacity: a deeper cargo area allows for more stacked or longer items but may also require reaching further inside.
The Kia Sportage, on the other hand, scores points in width and pass-through capability: the width at the narrowest point is 1.6 in (+4%) larger and the width of the trunk opening is 2.8 in (+7%) larger than the Duster, which facilitates loading wider, flatter items (e.g., furniture parts, wide boxes).
Additionally, the trunk with folded seats is slightly longer in the Sportage (+2 in; 3%), while the Duster offers somewhat more usable length with the first row upright (+2.8 in; 8%). These differences are moderate but influence suitability for certain loading tasks.
In summary: For tall or deeply stackable cargo, the Duster is the more practical choice due to the higher opening and significantly greater depth.
For wide, flat, or very wide items as well as slightly longer cargo space with folded seats, the Sportage has the advantage. Smaller differences such as the 1.6 in higher loading edge of the Duster (+6%) only slightly affect handling (somewhat higher lifting).
