How many 18 × 18 × 16 in boxes fit in a LWB panel van?
18 × 18 × 16 in boxes of 457 × 457 × 406 mm (also called 3 cubic foot boxes, medium moving boxes) in a Long-wheelbase panel van — inner dimensions 3,700 × 1,800 × 1,900 mm. Calculated by the Cubestow engine on 2026-09-08.
Boxes may be laid on any side. 57% of the space used, 4 layers high, about 1,190 kg (99% of payload). Payload-limited: 140 would fit by space alone. Open this load in the 3D planner →

The answer in detail
The "3.0 cubic foot" medium moving box (18 × 18 × 16 in) is the box most US movers use for the bulk of a household. Lying it on its side gains height in some containers, which is why the any-orientation count is higher.
Cargo area of a typical LWB high-roof van (Sprinter / Transit class): 3.7 m long between the bulkhead and the doors, 1.8 m wide at floor level, with wheel arches narrowing the floor to about 1.3 m in the middle — the plan here ignores the arches, so real loads may lose one row.
The simple grid estimate is 8 along the length × 3 across × 4 high = 96. The engine's validated plan holds 85, below the raw grid because the payload limit cap the load.

Frequently asked
How many 18 × 18 × 16 in boxes fit in a LWB panel van?
85 18 × 18 × 16 in boxes of 457 × 457 × 406 mm fit in a LWB panel van (inner dimensions 3,700 × 1,800 × 1,900 mm), boxes may be laid on any side. That uses 57% of the 12.7 m³ available and weighs about 1,190 kg.
What are the inner dimensions of a LWB panel van?
Typical inner dimensions are 3,700 mm long, 1,800 mm wide and 1,900 mm high (145.7 × 70.9 × 74.8 in), giving 12.7 m³ of space and a rated payload of about 1,200 kg. Individual units vary by a few centimetres, so check the actual box for tight loads.
Why does the payload limit matter for 18 × 18 × 16 in boxes?
Geometrically 140 18 × 18 × 16 in boxes would fit, but at about 14 kg each the LWB panel van's 1,200 kg payload is reached at 85. Heavy cargo fills the weight allowance before the space.
How was this number calculated?
By running the Cubestow 3D load-planning engine on the exact dimensions above, allowing all six orientations, stacking with at least 80% base support and the container's payload limit, then re-validating the plan for overlaps, support and weight. Real loads leave room for dunnage, door clearance and uneven cartons, so treat the figure as the practical maximum.
