New Era 59FIFTY fitted baseball cap
A 59FIFTY has a fixed crown height and a stiff flat brim, so the box lands close. Cap on its own would be sized from an average.
A hat is very light but needs enough of a box that it does not get crushed — figure a carton around 12 × 10 × 6 inches at about a pound. Because it is light and takes some space, price is set by the small box and the distance rather than weight. The lane and the service class fill in the rest, so quote the carton once the hat is inside it.
An 8 × 8 × 6 in cap carton weighing 0.7 lb quoted $9.57 with USPS Ground Advantage on the lane below.
On 2026-07-24 the SMKlog calculator was given “New Era 59FIFTY fitted baseball cap” and the route Dallas, TX 75201 to Pittsburgh, PA 15201. The carton, the weight, and the four rates below are exactly what it returned.

Packed weight 0.7 lb (0.3 kg).

Both ZIPs are live and were priced as entered. Texas to western Pennsylvania is a long zone count; a closer buyer would cut every figure here.
Volume decides it: 8 × 8 × 6 ÷ 139 works out near 2.8 lb where the scale reads 0.7 lb, so the prices rest on the carton rather than the cap. Nothing you do to the hat changes that; only the box does.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| USPS | Ground Advantage | $9.57 | 4-5 business days |
| FedEx | Smart Post | $10.62 | 4-5 business days |
| UPS | Ground | $11.52 | 4-5 business days |
| UPS | 3Day Select | $15.49 | 4-5 business days |
Each amount is a complete checkout price, label and SMKlog's share together, with nothing billed after the fact. USPS Ground Advantage was cheapest here at $9.57. Carriers adjust their tables and lanes vary widely, so take this as one cap on one day and quote your own ZIPs before you buy.
About 12 × 10 × 6 in once boxed. Anything with a shaped crown belongs in a carton rather than a bag, packed out with paper so handling cannot flatten it. A soft beanie has no shape to lose and travels fine in a poly mailer. For brim clearance and stuffing method, the hat shipping box guide goes further.
Under 1–1.5 lb packed. The bill follows the larger of scale weight and volume weight, and with a hat the volume side wins without a contest.
Distance, speed, and the size of carton the crown demands. Dallas, TX to Pittsburgh, PA is a long domestic run; a nearby delivery rates lower and an expedited service considerably higher. The same little box ranged from $9.57 to $15.49 in one sitting. No flat hat price would survive that, which is why the calculator asks for your route.
Around 12 × 10 × 6 in packed suits most caps. Use a rigid carton rather than a bag for anything structured, and fill the crown with paper so the shape holds through sorting. Unstructured knitwear can go in a poly mailer instead.
Usually under 1–1.5 lb packed. Measure and weigh the sealed box, because the charge takes the scale or length times width times height over a carrier divisor, whichever is greater, and guessing low produces a correction later.
Fit a rigid box to the hat, then pack crumpled paper into the crown and under the brim so the shape carries no load. A structured cap or a fedora should never go out in a soft mailer.
Yes. There is no shape in an unstructured beanie to protect, so a poly mailer is the cheapest sensible option. Keep the cartons for caps and stiff brims.
The box is the whole story. A structured hat needs a 12x10x6 inch carton, and UPS or FedEx bill that at its 5 lb dimensional weight rather than the 1 lb on the scale. Distance and speed account for the remainder. Type your route and packed size into the calculator to see live USPS, UPS, and FedEx pricing.
USPS Ground Advantage, in nearly every case. USPS applies dimensional weight only above one cubic foot, and a 12x10x6 inch hat box sits well under that line, so it bills the real 1 lb while UPS and FedEx bill 5 lb dimensional. That quirk of the rules makes USPS very hard to beat on hats. Buying at commercial rates online rather than at a counter typically saves another 20-40%.
