Patagonia Nano Puff insulated jacket
A named insulated jacket tells the estimator how much loft to allow for. A generic garment word would have been sized from an apparel average.
A folded jacket packs into a box around 16 × 12 × 5 inches. A thin shell weighs only 2–3 lb, but a down or insulated coat is bulky and light, and carriers charge on the volume of the carton rather than the reading on the scale, so a lofty jacket can price like something much heavier. Your own total still comes down to the lane, the service, and how small you can get the box.
Compressed to 12 × 8 × 6 in and 1.5 lb, this jacket quoted $11.17 with USPS Ground Advantage on the lane below.

12 × 8 × 6 in
30 × 20 × 15 cm
Packed weight 1.5 lb (0.7 kg).
Phoenix, AZ 85001
to Portland, OR 97201
Both ZIP codes were priced live, and the desert-to-coast distance is the biggest term in the four totals.
Volume decides this one: 12 × 8 × 6 ÷ 139 comes to about 4.1 lb against 1.5 lb on the scale, so the rates below are pricing the carton rather than the coat. Squeezing the loft out is the cheapest saving available.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| USPS | Ground Advantage | $11.17 | 4-5 business days |
| UPS | Ground Saver | $12.49 | 6 business days |
| FedEx | Smart Post | $13.32 | 4-5 business days |
| UPS | Ground | $13.58 | 4-5 business days |
Every row is the amount collected at checkout, postage and SMKlog's charge in one number. USPS Ground Advantage took this run at $11.17. Carriers rewrite their tables on their own schedule, so use these four for calibration and then quote the ZIP codes you actually ship between.
The rows below were all priced on 2026-07-25 across the Phoenix, AZ to Portland, OR lane from the example, which leaves the coat as the only thing changing. Open any row to load that description and route into the calculator.

On one unchanged lane, $5.87 separates the cheapest row from the dearest, and it is the packed parcel doing that, not the label on the coat. Rates drift with the carriers' own tables, so run your lane before anything is taped shut. The fold-and-bag routine behind these packages is in our guide to shipping clothes.
Around 16 × 12 × 5 in once boxed. Compress a puffy coat and pick the smallest carton it will sit in, since the loft you squeeze out comes straight off the volume you are billed for. A thin shell or rain jacket lies flat in a poly mailer instead.
2–4 lb packed. The higher of the two figures wins, scale or volume, so a lofty coat in a generous box ends up paying for the air around it.
Zones crossed, service chosen, packed size. Phoenix, AZ to Portland, OR is a long pull up the western states; a neighbouring-state lane comes in under it and an expedited service over it. Even so, the four quotes here sat between $11.17 and $13.58, because the parcel stays small once the loft is out.
Around 16 × 12 × 5 in packed. Squash a puffy coat down and use the smallest box that will hold it, because the loft you remove comes off the volume you are billed for. A thin shell or rain jacket ships flat in a poly mailer for less.
Figure 2–4 lb packed. Two numbers matter, the scale reading and the volumetric one (all three sides multiplied, then divided by the carrier's divisor), and the bill takes the bigger of them. Weigh and measure the packed box before you price it, or expect a correction on the invoice.
Because bulk is billed. A carrier charges for the space a carton occupies as readily as for its weight, and down is almost entirely space. An uncompressed jacket can price like a 6–8 lb parcel until you force the air out of it.
A thin shell goes in a mailer and ships at the lowest rate available. A thick or insulated coat does better in a right-sized carton you can compress it into, which holds the volume figure down.
Packed size, distance, and speed. At 16 x 12 x 5 in the volumetric figure is about 7 lb (L x W x H / 139) against 3 lb of actual weight, and UPS and FedEx charge the larger of the pair. A longer zone or a faster service lifts it further. The SMKlog calculator will price your route and your carton on live USPS, UPS, and FedEx numbers.
USPS Ground Advantage normally wins for something soft and light: parcels under 5 lb are its territory, and it skips volumetric pricing below one cubic foot, which this box stays under. Pack tight enough to keep it there. Buying the label online at commercial rates also runs 20-40% below counter prices for the same service.
