Measure smart

What to measure.

Four numbers decide nearly every fit check. Get these right and the rest follows.

01The trunk opening width and height, not the total volume, since the opening is what an item has to pass through.
02The load-floor length behind the rear seats, then again with the seats folded.
03The height available under the parcel shelf or roofline, measured at the lowest point.
04Your item at its widest point, including feet, handles, and packaging.

Don't make these

Common mistakes.

Most “it didn't fit” stories trace back to one of these oversights.

⚠Reading the cubic-foot figure and assuming a wide item will fit, when the trunk opening is narrower than the item.
⚠Measuring the cargo floor but forgetting the roofline tapers toward the trunk opening.
⚠Ignoring that a full-size spare, subwoofer, or hybrid battery eats into the quoted volume.
⚠Planning around seats-folded length while leaving a passenger seat up.
