Batch DIM weight calculator
Paste a list of packages, one per line, and get the billable weight at every carrier for each row, plus totals. Sellers use it to find which products in a catalog are quietly billing at two or three times their weight. It runs the same engine as the dimensional weight calculator, and the box size calculator then finds a smaller box for the worst rows.
Your package list
Inches and pounds, commas or spaces. Everything is calculated in your browser; nothing is uploaded.

Dispute evidence checklist
If the carrier's bill differs from this estimate, gather this evidence before you dispute:
- Photo of the packed box or pallet with a tape measure across each side
- Photo of the package on a scale showing the weight
- The label or bill of lading copy with the dimensions and weight you entered
- The carrier's adjustment notice with the recorded dimensions
- A screenshot or printout of this result, with the date
- Photos of all six sides if the carrier claims damage or a nonrectangular shape
- Your scale and tape calibration notes, if you have them
Questions
What format does the batch calculator accept?
One package per line: length, width, height, weight, and an optional quantity, separated by commas or spaces. Inches and pounds. Lines that do not have at least the four numbers are skipped and counted in the note under the table.
Is my product list uploaded anywhere?
No. The list is parsed and calculated in your browser. Nothing is sent to a server or stored. Reloading the page clears it.
How many rows can I paste?
Up to 500 rows are calculated. Past that, the first 500 are counted and the note under the table says so.
