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 package dimension in inches; dimensions are sorted automatically.

Width (in)

Second package dimension in inches.

Height (in)

Third package dimension in inches.

Max length

Maximum single-side length in inches from your carrier tariff.

Max L+girth

Maximum length plus girth in inches from your carrier tariff.

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. 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]

Girth

Girth, twice the sum of the two shorter sides, in inches.

L+girth

Length plus girth in inches.

Over length

Whether the longest side alone breaches the limit.

Over L+girth

Whether length plus girth breaches the limit.

Oversize

Whether the package is oversize under either limit.

• 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.

• Additional Handling Fee Trigger Checker

  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.

• 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.

• Concealed Damage Window Checker

  Check elapsed time against a configurable concealed-damage notice window. Confirm the applicable carrier contract, tariff, bill of lading, and law rather than treating the five-day planning default as a universal deadline.
