What size mattress fits in a Dodge Grand Caravan?

In most Dodge Grand Caravan configurations, a mattress can be transported flat in the cargo area once the rear seats are folded or removed. A full-size mattress (75 inches long) is the most dependable option, a twin fits easily, and a queen can fit in some layouts with careful setup. Always measure your specific vehicle to confirm.


Understanding the space and common options


The Grand Caravan’s interior uses Stow ’n Go seating, which allows second- and third-row seats to fold into the floor to create a long, flat cargo area. Exact clearance varies by year and trim, so measuring your vehicle after folding the seats is the surest way to know what will fit.


Common mattress sizes and how they typically fit in the Grand Caravan's cargo area when seats are stowed.



  • Twin (around 38 x 75 inches) — Fits easily along the cargo floor. This is the most straightforward option and leaves some width to spare for blankets or protective material.

  • Twin XL (around 38 x 80 inches) — Often fits if you need extra length, but you’ll want to verify the available cargo length with seats folded.

  • Full/Double (around 54 x 75 inches) — A reliable, commonly recommended choice; length is good for the floor, and width typically fits between interior walls with room to spare for protection.

  • Queen (around 60 x 80 inches) — Might fit in some configurations, but it is a tight squeeze and could require more aggressive seat folding or rearrangement. Measure first and be prepared to angle or slightly modify loading.

  • King (around 76 x 80 inches) — Generally not a practical fit for flat loading given interior width and length; not recommended.


Conclusion from these measurements: twin and full mattresses are the most dependable, twin XL and queen are possible in some setups, and king is unlikely to fit flat.


How to configure the Grand Caravan for a mattress


To maximize the cargo space for a mattress, plan ahead and use the vehicle’s seating features to create a flat floor. The following steps are typical for most Grand Caravans equipped with Stow ’n Go seating.



  1. Fold the second-row seats into the floor (Stow ’n Go) to create a continuous flat surface from the tailgate to the front seats.

  2. Fold the third-row seats flat as well to extend the cargo length. This combination often yields the maximum available length for a mattress.

  3. Move the front passenger seat forward if necessary to gain extra length for longer mattresses (avoid driving with the mattress protruding into the cabin during transit).

  4. Protect the interior: lay moving blankets, tarps, or old sheets on the cargo floor and over edges to prevent damage to the mattress and trim.

  5. Load the mattress slowly, keeping it aligned with the floor and avoiding sharp bends; secure it with straps or cords if you will be driving with it in place.


Following these steps can help you maximize space and reduce the risk of damage to both the mattress and the vehicle’s interior.


Practical tips and measurements


Before buying a mattress, or attempting to transport one, take precise measurements of both the mattress and your Grand Caravan’s cargo area in its loaded configuration. The exact fit depends on year, trim, and whether the seats are folded as far as possible.



  • Measure from the tailgate to the back of the front seats with both rows folded to confirm available length for the mattress.

  • Measure the interior width at the widest point between trim panels, considering wheel wells or intrusion points.

  • Account for protective coverings and any intrusion from door sills or brackets that could limit fit.

  • Consider loading the mattress diagonally if needed, but ensure it remains secure and does not obstruct visibility or movement.


These practical checks help prevent purchasing a mattress that won’t fit and ensure safe loading and travel.


Summary


A Dodge Grand Caravan can accommodate a mattress most reliably in its twin or full sizes when the Stow ’n Go seats are folded into the floor. A queen may fit in some setups but requires precise measurement and careful loading, while a king is generally impractical for a flat fit. Always measure your specific vehicle configuration after folding the seats to confirm fit, use protective coverings, and load with care to protect both the mattress and the van’s interior.
