Fold the garment flat, band it in tissue, slide it into a poly mailer, and let the label do the rest. Fabric survives anything a sorting facility can do to it, which makes clothing the rare shipment where the packaging question is purely about price, and the live quotes below put numbers on it.
Tell the calculator what garments you are sending and it estimates the packed mailer or carton before quoting live services.
All three ran on 2026-07-27 over Newark, NJ 07102 to Atlanta, GA 30303, and each price is the cheapest of the five live services returned, full checkout amount included.
| What shipped | Package | Best service that day | Price |
|---|---|---|---|

| One winter coat, boxed | 19.7 × 15.7 × 5.9 in carton 4.4 lb | UPS Ground Saver | $17.56 |
| Full box of folded clothes | 17.7 × 13.8 × 11.8 in carton 15 lb | UPS Ground Saver | $22.62 |
Study the jumps. Fifteen pounds of wardrobe cost only modestly more than one bulky coat, because clothing shipments are priced by package, not by garment count. Consolidating an order into one carton is where sellers quietly win, and staying flat in a mailer is where single garments do.
Fold to the mailer's footprint, wrap in tissue and band it, seal a clear inner bag against weather, then the poly mailer with its strip pressed edge to edge. Flat packages also duck volume-based pricing entirely, which our bag-versus-box experiment demonstrates service by service.
Blazers, structured hats, embellished dresses and leather want a carton with tissue between folds. The couple of dollars a bag would save is exactly what an unwrinkling steam session or a return costs you back.
Vacuum bags shrink puffers and knits wonderfully and crease everything tailored. Compress only what a dryer could rescue, and remember the scale still sees every pound even after the air is gone.
A poly mailer on a slow ground service. Two folded t-shirts in a 10 by 13 bag quoted $9.91 with USPS Ground Advantage on 2026-07-27, Newark to Atlanta, and every service priced the bag below the equivalent small box that day.
Whenever the garment has structure to lose: tailored jackets, hats, pleated or beaded pieces, leather, and anything on a hanger you want to arrive presentable. A carton holds its shape through sorting; a bag transmits every squeeze.
No cushioning, but yes to moisture defense. Fabric does not break, so skip the bubble wrap and instead seal the folded garment in a clear inner bag before it goes into the mailer, in case the package rides in rain.
Our 15 lb box of folded clothes quoted $22.62 with UPS Ground Saver on 2026-07-27, Newark to Atlanta, and a single boxed winter coat ran $17.56 the same day. Per garment, the big box is by far the better deal.
