Geometric fit, not just volume
Real 3D fit-checking. A long item won't get squeezed into a cube just because the volumes happen to work out, and items won't be forced into the wrong orientation. Length, width, and height are all honored.
A Shopify app
The right shipping box, every order. Automatic.
Boxfit looks at each order, picks the smallest box that actually fits, writes the total package weight to the order, and shows your packer exactly what to grab. No spreadsheets, no manual lookups, no surprises when you hit the post office counter.

What it does
Five capabilities, done carefully.
Total weight, automatically
Boxfit adds the empty (tare) weight of the chosen box to your item weights so the number on the shipping label is the number you'd see on a scale. No more shipments coming back from the carrier underweight.
Graceful overflow handling
When an order is too big for any single box, Boxfit picks the closest match and flags what doesn't fit, so the packer can make a call instead of staring at a generic "No fit" error. (Most apps give up here.)
Packer-friendly output
The selected box and total weight show up on the printed packing slip itself. No Liquid template edits, no second app to install. The person at the bench reads it once and packs.
Bulk dimensions, your way
Every product in your catalog is already listed on the Boxfit dashboard, ready to edit inline. Or export a CSV with the columns pre-filled, edit in Excel, and upload it back. No per-product clicking required.
