1. Inputs
We load package dimensions per box and vehicle constraints per config (opening, cargo length/width/height).
How Car Fit Check works
Car Fit Check is deterministic. For each package and seat configuration, we compare required dimensions against opening and cargo limits, then classify the result into YES, MAYBE, or NO using fixed thresholds.
Computation flow
2. Orientation checks
Each package is evaluated across eligible orientations (for example straight or diagonal), then the best valid orientation is selected.
3. Margin classification
Margin thresholds map directly to result classes: safe positive margins produce YES, borderline margins produce MAYBE, and negative margins beyond threshold produce NO.
4. Page synthesis
The result page presents package table, limiting factor, assumptions, FAQ, and alternatives generated from deterministic rules.
What we measure (glossary)
Opening width & opening height
These are the pass-through measurements at the trunk hatch. If a box cannot clear the opening, it will not load, even if it would fit deeper inside.
Boot floor width (narrow point)
This is the usable width inside the trunk between wheel arches or interior trim. It often differs from opening width.
Boot length (seats up vs seats down)
We evaluate both configurations separately because usable length and geometry can change significantly when seats fold.
Why we show margins
Margins show how much spare space you have (positive) or how short you are (negative). Tight margins are treated as borderline.
Result definitions
YES
Margin is above the safe threshold for the selected config and orientation.
MAYBE
Fit is borderline near the threshold. It can work, but loading precision matters.
NO
At least one critical dimension fails by more than the borderline range.
Important assumptions
- Fit is evaluated per package, not guaranteed as full stacked cargo packing.
- Real-world trunk obstacles can reduce usable space in tight scenarios.
- Derived dimensions are explicitly flagged in assumptions and confidence.
