What size trunk organizer should I get?

Reviewers we read recommend matching the organizer's footprint to your cargo floor: roughly 20–22 inches for sedans and compact SUVs, and 30+ inches (or a 65–95L bin) for midsize and large SUVs. Oversized organizers in small trunks tend to bow inward when only partially filled, which is one of the most common verified-purchase complaints across the category.
