How many 20 × 20 × 20 in boxes fit in a LWB panel van?
20 × 20 × 20 in boxes of 508 × 508 × 508 mm (also called 4.6 cubic foot cube 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. 65% of the space used, 3 layers high, about 756 kg (63% of payload). Open this load in the 3D planner →

The answer in detail
A 20 in cube — used as a master carton for lightweight bulky goods (pillows, packaging, toys).
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 7 along the length × 3 across × 3 high = 63. Here no mixed pattern beats the best uniform grid, so the engine's plan is exactly that grid (63).

Frequently asked
How many 20 × 20 × 20 in boxes fit in a LWB panel van?
63 20 × 20 × 20 in boxes of 508 × 508 × 508 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 65% of the 12.7 m³ available and weighs about 756 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.
How much does a full load of 20 × 20 × 20 in boxes weigh?
63 × 12 kg ≈ 756 kg, which is 63% of the 1,200 kg payload — so this load is limited by space, not weight.
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.
