Packaging Calculators Hub
Run a Packrift calculator before ordering
Each calculator answers one buyer question — box size, mil thickness, DIM weight, packaging cost — and outputs a SKU recommendation or cost number you can act on.
All calculators are free and require no account.
Pick the calculator for the question you have, run it with your inputs, then click into the recommended SKU.
Size and fit
- Open the box size calculator — enter product dimensions, get a recommended Packrift box size
- Open the mailer vs box selector — pick a mailer or a box for the item being shipped
- Open the poly bag thickness selector — pick 2, 4, or 6 mil by item type
Cost and weight
- Open the DIM weight calculator — calculate UPS, FedEx, USPS DIM weight from box dimensions
- Open the packaging cost per order calculator — sum per-unit cost across box, void fill, tape, label

Why buyers use Packrift's calculators
- Inputs are item dimensions or SKU lists, not abstract sizes → answers in concrete Packrift SKUs
- No account, no email gate → run once, get an answer, click through to checkout
- DIM, cost, and fit all on one site → no cross-tool reconciliation when picking the cheapest packing line
- Carrier-specific DIM divisors (UPS, FedEx, USPS) → match the actual carrier billing your shipper uses
Fit / not the right fit
Packrift's calculators are a good fit if you ship parcel ground in the US and want a fast SKU recommendation or a per-order cost estimate.
Packrift's calculators are not the right fit for international LTL freight rate quoting, custom-corrugated cost modeling, or buyers who need a CRM-integrated quote tool.
