Trunk comparison: Mercedes Benz GLB vs Skoda Fabia

Key Differences

The Mercedes‑Benz GLB offers a significantly longer cargo space than the Škoda Fabia: with the seats folded down, the GLB is 14.2 in (26%) longer, and with the first row upright, it is 8.3 in (28%) longer. At its narrowest point, the GLB's cargo area is also 4.7 in (13%) wider.

In contrast, the Škoda Fabia has a considerably greater "depth" in the trunk (loading edge → trunk floor): this is 2.8 in (58%) higher in the Fabia than in the GLB. Smaller differences (opening height +7%, opening width +6%, loading edge height +6%) exist but hardly affect practical use.

What impact does this have on usability?

The larger length dimensions of the GLB make it much better suited for long items (e.g., skis, slats, furniture parts) and for transporting elongated luggage, even when passengers are still seated.

The greater minimum width makes loading bulky or wide suitcases easier and generally makes storing irregularly shaped cargo less problematic.

The Fabia's greater trunk depth measurement (loading edge to floor) practically means the cargo space has a deeper well: this can be advantageous when items need to lie lower and more stably below the loading opening or when smaller cargo packages are stacked without protruding over the loading edge.

However, a deeper well can make handling very heavy items more difficult because lifting in and out feels deeper; combined with the somewhat narrower width and significantly shorter length, this limits flexibility for long or wide cargo items.

Conclusion: For longer, wider, or bulky cargo, the GLB is the more practical choice. For compact, stackable everyday cargo, the Fabia can offer advantages due to its deeper loading well but loses significant flexibility compared to the GLB for large/long items.
