Trunk comparison: Ford Focus vs VW Taigo

Key Differences
The depth of the trunk (loading edge to trunk floor) of the VW Taigo is 0.8 in (11%) greater than that of the Ford Focus. Other measured differences are significantly smaller: the Taigo has only +0.4 in (1%) more trunk space with the seats folded down and +2 in (6%) more with the first row upright.
The height of the trunk opening is the same. The loading edge of the Taigo is +2.4 in (9%) higher above the road. At the narrowest point, the Focus is +0.8 in (2%) wider; the trunk opening of the Focus is +0.4 in (1%) wider than that of the Taigo.
What does this mean for usability?
The greater trunk depth of the Taigo practically means more usable built-in depth behind the loading edge: somewhat better stacking or storing of taller/bulkier luggage and thus slightly higher usable cargo capacity with the same base area.
On the other hand, the slightly higher loading edge of the Taigo makes lifting heavy items a bit more strenuous (difference here: +2.4 in / 9%).
The marginally greater width at the narrowest point and the minimally wider opening on the Focus only slightly ease loading very wide items. Differences with folded seats or with the first row upright are so small that they are hardly noticeable in practical use.
In summary: The Taigo offers a noticeable, though moderate, advantage for bulky or stackable loads due to the approximately 11% greater depth. The Focus has slight advantages in easier handling and loading very wide items, but these advantages are clearly smaller.
