Frequently asked questions
Quick answers about how fit checks are computed, what the result states mean, and how to use the details on each page.
How do you decide YES, MAYBE, and NO?
Each package is scored against opening and cargo limits. Margin thresholds classify the outcome: safe positive margin is YES, borderline band is MAYBE, and clear failure is NO.
Is MAYBE caused by missing data?
Published fit pages are expected to have complete core dimensions. MAYBE means borderline fit, not unknown fit.
Are results generated at runtime?
Main fit pages are statically generated so key result text is available in HTML on first paint.
Do all packages fit together when result is YES?
Fit is evaluated per package. Individual package fit does not always guarantee stacked simultaneous loading.
Why can seats-up and seats-down results differ?
Cargo length and access geometry can differ by seat configuration, so each config is evaluated independently.
What is the limiting factor?
The limiting factor is the tightest measured constraint for the selected package/config, such as opening width or cargo height.
How should I use a MAYBE result?
Treat MAYBE as tight but possible. Use the suggested orientation and verify the tightest point in your car before loading.
What confidence means on the result page?
Confidence is a bounded score derived from fit margins and available dimensions, intended as a guidance signal rather than a guarantee.
Do you only cover IKEA products?
Current public catalog focuses on IKEA packaged items. The same model supports other packaged products when data is available.
How often is data updated?
Pipeline data can be refreshed as new sources are parsed and exported. Versioning tracks export and engine revisions.
