Pallet Load Calculator
Optimize palletization and freight shipping efficiency. Calculate the maximum number of shipping cartons that fit on a standard industrial pallet based on box dimensions, layer tier limits, and maximum forklift load weight constraints.
Outer carton length dimension
Outer carton width dimension
Outer carton height dimension
Gross weight of one packed carton
Maximum allowed pallet height including 5" pallet base
Maximum number of cartons securely stacked on the pallet
How to Use This Calculator
- Enter length, width, and height of your master shipping cartons in inches.
- Enter the gross weight of one packed carton in pounds.
- Enter the maximum allowable pallet load height (typically 48" to 72" for standard semi-trailers).
- Review total cartons per pallet and gross shipping weight to prevent axle weight overloads.
Formula & Calculation Methodology
Determines the optimal carton orientation fitting a standard 48" x 40" pallet footprint and multiplies by allowable vertical tiers.
Worked Example
16x12x10" cartons weighing 25 lbs on a 48x40 pallet with a 60" height limit
Frequently Asked Questions
What is the maximum weight capacity of a standard wood GMA pallet?↓
A standard 48x40-inch wooden GMA pallet safely supports 2,500 to 2,800 pounds of evenly distributed static load and up to 2,200 pounds of dynamic forklift transit weight.
What is standard pallet overhang and is it allowed?↓
Overhang occurs when cartons protrude beyond the 48x40-inch pallet edge. Overhang reduces carton compression strength by up to 30% and frequently causes freight carriers to reject shipments.
How does pallet tie-layer interlocking increase stability?↓
Interlocking patterns rotate carton orientation between alternating layers (like brickwork), preventing column collapse and eliminating the need for excessive plastic stretch wrap.
What is the maximum pallet height allowed in standard ocean shipping containers?↓
Standard dry shipping containers have an internal door height of 90 inches. Pallets are typically stacked to a maximum height of 45 inches (double-stacked) or 86 inches (single-tier).
