Online Shipping Container Loading Calculator
Estimate container stuffing capacity for ocean freight. Compute how many cartons or pallets fit inside 20ft, 40ft, or 40HC shipping containers.
Sea Container Loading & Capacity Calculator (20ft / 40ft / 40HC)
Calculate CBM volume utilization, payload weight limit, and identify bottleneck constraints
Container Capacity & Bottleneck Analysis
How to use
- Select container type (20ft Standard, 40ft Standard, 40ft High Cube).
- Enter carton dimensions (L × W × H) and unit gross weight.
- Choose palletized or floor-loaded loose cartons.
- View computed cargo quantity, cubic volume utilization, and payload limits.
Standard Container Specs
20ft GP Container: usable volume ≈ 33 m³, payload up to 21.7–28 tonnes, holds 11 Euro pallets.
40ft GP Container: usable volume ≈ 67 m³, payload up to 26–28 tonnes, holds 24–25 Euro pallets.
40ft HC Container: usable volume ≈ 76 m³, extra height up to 2.69 m, ideal for lightweight voluminous freight.
Calculation Methodology
Estimates apply usable internal dimensions, door opening clearance, real-world packing efficiency (80–85%), and ISO maximum gross mass constraints.
Frequently Asked Questions
How many pallets fit in a 20ft and 40ft container?
A 20ft container fits up to 11 Euro pallets (1200×800mm); a 40ft container fits up to 24–25 Euro pallets on floor level.
Why is packed volume lower than theoretical container volume?
Carton stacking gaps, pallet bases, ceiling clearances, and door opening restrictions reduce usable cubic space.
What is the advantage of a 40ft High Cube container?
It provides an extra 30 cm (1 foot) in interior height, adding around 9 m³ of cargo volume.
What is the maximum permissible payload?
Typical maximum container payload is approximately 26,000–28,000 kg depending on tare weight.
