How this estimate works

The result uses the formula below. Check the measurements, unit setting, and applicable carrier or supplier rule before using it.

Length + girth = longest side + 2 × (second side + shortest side)

Carrier size limits and measurement rounding vary. Enter the limit shown in the applicable service guide or contract.

This calculator is a planning aid, not a carrier quotation, engineering assessment, or professional advice. Verify critical figures against current supplier and carrier documentation.
