Will It Fit in My Car?
Enter your item dimensions and cargo area measurements to see if it fits — trunk, backseat, or roof rack.
Whether it fits depends on measurements most people get wrong.
Key Measurement
Cargo length (seats folded) vs. item length
Standard Dimensions
Item: Varies — measure your specific item
Space: Sedan trunk: ~42" L × 44" W. Mid-size SUV (seats folded): ~72" L × 44" W
Actual clear openings are usually 1–2″ smaller than the labeled size.
Your exact dimensions probably aren't "standard." Small measurement errors cause big problems — 1 inch can be the difference between fitting and getting stuck.

What to Measure
- 1Trunk opening vs. interior dimensions — the trunk or hatch opening is almost always 6–10" narrower than the cargo space inside, so measure both
- 2Folded-seat cargo expansion — folding the rear seats typically doubles usable length from 35–42" to 60–80", creating a flat(ish) cargo floor
- 3Diagonal loading technique — loading an item corner-first at 30–45° uses the cargo area diagonal, which is 15–20% longer than the straight length
- 4Fragile item padding strategy — soft items (pillows, blankets, clothing bags) should fill gaps around rigid cargo to prevent shifting and absorb vibration
Common Mistakes to Avoid
- Measuring cargo length with seats up — folding the rear seats usually doubles usable length; always measure with seats in the planned configuration
- Assuming the trunk opening matches the interior — the trunk lid or hatch opening is typically 6–10" narrower than the cargo space inside
- Not accounting for wheel well intrusions — wheel wells protrude 3–6" per side at floor level, reducing usable width where it matters most for flat items
- Forgetting to check cargo area height — sedans have only 20" of trunk height, while SUVs offer 30–40", which determines whether boxy items fit
Frequently Asked Questions
Can I fold my rear seats to make more room?
Most modern cars have a 60/40 or 40/20/40 split-fold rear seat. Folding all sections creates a flat(ish) cargo floor extending from the trunk to the front seats. Check your owner's manual — some seats fold but leave a raised lip or gap between the trunk floor and seat back.
What is the diagonal loading technique?
Place the item corner-first into the trunk, then rotate it diagonally across the cargo area. A flat item that won't fit straight in often clears the opening when loaded at a 30 to 45 degree angle. Diagonal length is always longer than either straight dimension.
Should I use a roof rack for oversized items?
Roof racks work well for long, flat items like lumber, shelving boards, or mattresses in bags. Check your vehicle's roof load rating (typically 100 to 165 lbs for crossbar racks). Secure items with ratchet straps, not bungee cords, and add a red flag to anything extending past the rear bumper.
