Trunk comparison: Ford Focus vs Opel Astra Wagon

Key Differences
The biggest differences lie in the usable cargo space with the front seats upright, the trunk depth (loading edge to trunk floor), and the loading edge height relative to the road.
Specifically, the Opel Astra Wagon is 11.8 in (≈39%) longer when the front seats are upright. The Ford Focus has a significantly greater trunk depth: +6.3 in (≈800%) compared to the Astra.
Additionally, the loading edge of the Ford sits 3.9 in (≈17%) higher above the road. Smaller differences (e.g., +4.3 in/7% more length with folded seats in favor of the Astra, slightly narrower spots and opening width) exist but do not exceed the 10% mark and are therefore less decisive.
Implications for Practical Use
The longer loading surface of the Astra with the rear seat upright (39% more) makes it more practical for longer items that need to be transported without rearranging or folding the front seats (e.g., slats, skis, or long packages).
Those who frequently carry long cargo with full rear seating have significantly fewer restrictions with the Astra.
The greater trunk depth of the Focus means the cargo floor lies further below the loading edge. This creates more storage space in depth and allows flatter items to be recessed deeper but reduces direct reach into the cargo area.
In practice, this means heavier or bulky parts must be lifted higher but then pushed further inside; bulky items with low height can possibly be stored more compactly in the Focus.
The higher loading edge of the Focus (+3.9 in) increases the effort required to lift loads into the trunk. For regular loading of heavy goods, the Focus is less ergonomic; the Astra with its lower loading edge is easier to load and unload, especially for shopping bags, strollers, or bulky, heavy items.
Summary
The Opel Astra Wagon is the more practical choice for users who prefer longer items with the rear seat upright or generally easier access with a lower loading height.
The Ford Focus offers more "recessed" storage space due to its greater trunk depth, combined with a higher loading edge, which complicates handling heavy loads.
Which of the two configurations fits better depends on whether length with full seating (Astra) or additional depth storage despite a higher loading edge (Focus) is more important.
