Use this logistics calculation for a transparent shipment, inventory, warehouse, customs, packaging, carrier, or service-level estimate when the governing units and business rules are explicit.

Length (in)

One parcel side in inches; side order does not matter.

Width (in)

A second parcel side in inches; side order does not matter.

Height (in)

The remaining parcel side in inches; side order does not matter.

Weight (lb)

Actual package weight in pounds.

Max longest side (in)

Longest-side threshold in inches.

Max second-longest side (in)

Second-longest-side threshold in inches.

Max weight (lb)

Actual-weight threshold in pounds.

Max length plus girth (in)

Length-plus-girth threshold, where length is the longest side and girth is twice the sum of the other sides.

Check a rectangular parcel against configurable longest-side, second-longest-side, actual-weight, and length-plus-girth thresholds; packaging and service-specific rules are outside this numeric screen. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Longest-side trigger

Whether the longest side exceeds its threshold.

Second-longest-side trigger

Whether the second-longest side exceeds its threshold.

Weight trigger

Whether actual weight exceeds its threshold.

Length-plus-girth trigger

Whether length plus girth exceeds its threshold.

Additional handling applies

Whether any configured numeric trigger fired.

• Carrier tariffs, customs rules, dangerous-goods requirements, hours-of-service rules, surcharges, port terms, dimensional divisors, and service definitions vary by jurisdiction, contract, date, mode, and commodity. A calculation is not a booking, classification, or compliance determination.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify current carrier and authority documents, retain shipment dimensions and timestamps, test boundary cases, and reconcile estimates against invoices and operational scans.

• Oversize Package Threshold Checker

  Test a parcel against oversize thresholds using the longest side as length and twice the sum of the other sides as girth. Defaults are 108 in length and 165 in length-plus-girth; override them to match your carrier.

• Certificate of Origin FTA Threshold Check

  Screen achieved regional value content against an agreement-specific threshold and optional shortfall allowance. Only use the allowance when the applicable rule explicitly permits it in RVC percentage points; this calculation does not establish preferential origin by itself.

• Billable Weight (Max of Actual vs Dim) Calculator

  Compare actual and volumetric weight before carrier-specific dimension, weight, or billing rounding; an exact tie uses actual weight.
