Will the protected item fit the box?

Check interior geometry before buying a carton. This does not set a shipping price or establish that your chosen cushioning is adequate.

Use the bench in three moves

  1. Check product safety, permitted saleability and actual terms first.
  2. Fill every applicable cost; keep unknown assumptions labelled, not silently zero.
  3. Read the method and exclusions, then change one assumption to test the downside.

Use actual costs or clearly chosen scenarios. Enter zero explicitly where a cost does not apply. Our application does not send or save these entries.

Read the tape

No sale modeled yet. Enter the costs above.

Method and boundaries

Required interior dimension on each axis = item dimension + twice your chosen cushioning thickness. Compare each with the corresponding box interior dimension. The entered orientation is fixed; rotate by entering the dimensions in a different order if appropriate. A negative difference means insufficient room on that axis. Uses geometric space only: thickness is your assumption, not a carrier packing recommendation. Does not model compression, dividers, multiple items, box strength, fragile-item protection, mailable contents, outer dimensions, actual/dimensional weight or postage. Weigh and measure the final OUTSIDE parcel and obtain a current official carrier quote.

Worked example · hypothetical, not an actual seller

One axis stops the fit

Item 10 × 8 × 4 inches, chosen padding 1 inch on every side, usable box interior 11 × 10 × 6 inches. One inch is not a packaging recommendation.

Required interior 12 × 10 × 6 inches. Length is short by 1 inch. Geometry only: no claim about adequate protection, mailability or postage.
