What we typed
Queen size down alternative comforter, compressed
Two words do the work here: “queen” sets the fabric volume and “compressed” halves the box. Write just “comforter” and the estimate defaults to an uncompressed category average.

How much does it cost to ship a comforter?
A queen comforter vacuum-compressed packs near 20 × 18 × 12 inches at 5–10 lb. Uncompressed, the same comforter can triple its dimensional weight — compression is the difference between a cheap ground label and a painful one. After the vacuum bag has done its work, quote the box you actually produced on the lane you actually need.

Nothing here is a ballpark: an 18 × 18 × 10 in box at just 3.3 lb rated $35.06 on UPS Ground Saver over the Detroit-to-Vegas lane below.

Route

to Las Vegas, NV 89101
Detroit to Las Vegas, quoted live against real ZIPs. After compression, lane distance is the biggest remaining cost input; the same bagged comforter to a nearby state would rate far below this.
Even compressed, this is a volume purchase: the box computes to about 23.3 lb dimensional (18 × 18 × 10 ÷ 139) while the comforter itself weighs 3.3 lb, so carriers charge for the cube, not the fabric. Every further inch squeezed out of the bag pays for itself immediately.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| UPS | Ground Saver | $35.06 | 6 business days |
| FedEx | Smart Post | $38.90 | 8-9 business days |
| UPS | Ground | $42.13 | 5-6 business days |
| FedEx | Ground | $52.57 | 5-6 business days |
Each row is a finished checkout price; the label and SMKlog's charge are already merged and nothing else follows. UPS Ground Saver took this comparison at $35.06. Read the table as one day's evidence rather than a menu. Tariffs move, seasons shift demand, and your ZIP pair will produce its own numbers, so quote fresh before you pack.
Typical packed size
About 20 × 18 × 12 in once boxed. Vacuum bags matter more here than for any other bedding: a king down comforter shrinks to a third of its size. Let the bag settle for an hour, then box it — down slowly re-expands and can bow a thin box.
Packed weight
5–10 lb packed. The scale barely matters for bedding; billing takes the higher of actual and dimensional weight, and an airy comforter box loses that contest every time, which is the whole case for vacuum bags.
What moves the price
Packed volume first, then lane, then speed. Detroit to Las Vegas is a long haul, and across four ground-class services the identical box spread from $35.06 to $52.57. A shorter route sits below that band; air sits above it. One universal comforter price can't exist, so the calculator builds yours from your inputs.
Measured: what compression actually saves
Same queen comforter, same 8 lb on the scale, same route — Berkeley Heights, NJ 07922 to Denver, CO 80202. The only difference is the box: loose in a 24 × 18 × 14 in carton, or vacuum-bagged down to 20 × 16 × 8 in. Both priced on 2026-07-25.
| Service | Loose in a big box | Vacuum-bagged | You keep |
|---|---|---|---|
| UPS Ground | $53.61 | $31.86 | $21.75 |
| FedEx Ground Economy | $64.14 | $28.05 | $36.09 |
| UPS Ground Saver | $75.37 | $27.99 | $47.38 |
| USPS Ground Advantage | not offered at that size | $30.54 | — |
The scale never moved. Every dollar in that last column is dimensional weight: the loose box computes to about 44 lb billable, the compressed one to about 18 lb. Compression also drops the package under the size cut-off where USPS Ground Advantage starts quoting at all, which is why the cheapest option on the right does not even appear on the left. Squeeze the air out, let the bag settle for an hour so the down stops re-expanding, then measure the box you are actually shipping.
Shipping a comforter: common questions
What box size do I need to ship a comforter?
Plan around 20 × 18 × 12 in packed. Vacuum bags matter more here than for any other bedding: a king down comforter shrinks to a third of its size. Let the bag settle for an hour, then box it — down slowly re-expands and can bow a thin box.
How much does a comforter weigh packed for shipping?
Typically 5–10 lb packed. The number on the invoice is whichever is bigger: the scale weight, or the box's length × width × height divided by the carrier's divisor. Measure the compressed package as it will actually ship; optimistic dimensions get corrected by the carrier, with a fee, after the fact.
How do I ship a king size comforter cheaply?
Vacuum-compress it, then measure the packed box honestly and compare ground services — on bulky bedding the gap between carriers for the same route is often $10–20. Avoid oversized boxes: dimensional weight is billed even if the box is half air.
Will vacuum compression damage a down comforter?
Short trips in a vacuum bag are safe for down. Avoid storing it compressed for weeks — for a normal shipping window of 2–7 days the loft recovers fully after a day of airing out.
How much does it cost to ship a comforter?
You pay for air. A boxed comforter is about 20x18x12 in but only 7 lb; carriers bill the greater of actual and dimensional weight, and that box computes to roughly 31 lb dimensional — over four times the scale weight. Packed volume is the main cost driver, followed by distance zone and ground versus expedited speed. To see what your own compressed box costs, run it with both ZIPs through the SMKlog calculator for current USPS, UPS, and FedEx pricing.
Can I ship a comforter in a poly mailer instead of a box?
Yes — all major carriers accept soft goods in poly mailers, and it's often the single best way to cut the cost. A compressed comforter in a bag measures far smaller than a 20x18x12 box, and dimensional weight is calculated on the packed size, whichever container you use. Use a thick mailer, squeeze the air out before sealing, and add a plastic liner inside in case the outer bag tears.
