Suggested packaging
Suggestions are heuristics for planning. Always confirm carrier rules for “Flats,” “Letters,” and restricted services like Media Mail.
Disclaimer: Results are estimates. Dimensional‑weight examples use common divisors (in³/lb: 139 & 166; cm³/kg: 5000 & 6000).
Carriers change rules and thresholds—verify final service eligibility and pricing at checkout.
