USPS, UPS and FedEx each draw their own line before a box counts as freight instead of a parcel, and the lines are not the same line. A 72 lb tool chest boxed to 34 x 26 x 18 in, quoted live on 2026-08-28, cleared two of the three and still shipped for $111.86 — cheaper than most sellers assume once a listing photo starts looking big.
The box below cleared UPS and FedEx on 2026-08-28 without touching a freight quote. USPS was the one carrier it missed, on weight alone.
A listing photo makes a bulky item look unshippable long before the carriers agree. USPS's own Ground Advantage page draws the line at a flat 70 lb, with a combined length-and-girth ceiling of 130 in — girth being the distance around the thickest point of the box, read 2026-08-28. UPS publishes a roomier pair on its shipping dimensions page the same day: up to 150 lb, 108 in of length on its own, and 165 in once length and girth are added together.
| Carrier | Max weight | Max size |
|---|---|---|
| USPS Ground Advantage | 70 lb | 130 in, length plus girth combined |
| UPS | 150 lb | 108 in length; 165 in length plus girth combined |
FedEx publishes a comparable ceiling on its own FedEx Ground page, which returned an access error rather than content when we checked it on 2026-08-28. Rather than reprint a figure we could not confirm that day, the current sourced number lives on our own FedEx parcel pricing page instead of being repeated here from memory.
eBay's Seller Center names the same ceiling in plainer terms on its freight guidance page, read 2026-08-28: “Most small package carriers including USPS, FedEx, and UPS only support items up to certain weights and dimensions.” The page points sellers toward freight once an item is genuinely oversized — appliances, furniture, large car parts or gym equipment are the examples it gives — rather than at any specific pound figure of its own.
A freight listing on eBay prices two ways. One flat cost applies regardless of how far the buyer is, or a freight rate table carries up to 100 regional prices so distance is reflected without a message exchange before the sale. Either way, the seller hands the shipment to the carrier and the carrier takes over quoting, booking and transit with the buyer from there — a genuinely different job than buying a parcel label.
To see where the line actually sits, we described a rolling tool chest with drawers, boxed to 34 × 26 × 18 in at 72 lb, and quoted it from Berkeley Heights, NJ to Chicago, IL. Every service that answered is below, unedited.
| Carrier | Service | Price | Quoted transit |
|---|---|---|---|
| UPS | Ground | $111.86 | 4-5 business days |
| UPS | 3 Day Select | $164.48 | 3-4 business days |
| FedEx | Ground | $213.33 | 4-5 business days |
| UPS | 2nd Day Air | $221.88 | 3-4 business days |
| UPS | 2nd Day Air A.M. | $254.62 | 3-4 business days |
UPS returned every tier it sells for this box; FedEx returned one. None of these five rows is a freight quote — freight review is for weight and bulk beyond what a table like this can price, not for a box that already has a parcel rate sitting in front of it.
Carriers bill the package, and girth is length plus twice the width and twice the height. A frame or a tube can read as compact on a tape measure and still land past a girth ceiling that a square carton of the same weight clears easily.
Padding, hardware and the box itself add pounds that a bathroom scale under the bare item never sees. The tool chest above missed USPS by 2 lb once packed — exactly the margin that a pre-listing weigh-in would have caught.
Anything that fails every ceiling above stops being a parcel question. Freight review puts a person on the lane instead of forcing a size into a table built for boxes.
Carriers and eBay both revise these pages without notice. What is above is what those three sources published on the date shown; check the live page before you commit a listing to one option or the other.
Up to the carrier's own ceiling, not a size that merely looks big in a listing photo. USPS Ground Advantage stops at 70 lb and 130 in of length plus girth combined, read from usps.com on 2026-08-28. UPS allows up to 150 lb, 108 in of length, and 165 in of length plus girth, read from ups.com the same day. A 72 lb tool chest boxed to 34 x 26 x 18 in, quoted live on 2026-08-28, still came back with parcel rates from UPS and FedEx, just not from USPS, which the weight alone rules out.
When the item sits past every parcel ceiling above, or matches what eBay names directly. eBay's Seller Center states that most small package carriers, including USPS, FedEx and UPS, only support items up to certain weights and dimensions, and it points sellers toward freight for oversized items such as appliances, furniture, large car parts or gym equipment.
Either. A freight listing on eBay can quote one flat cost regardless of distance, or run off a rate table with up to 100 regional prices, so a buyer sees a number at checkout instead of waiting on a message back and forth before the sale closes.
Weight, not size. The box measured 34 x 26 x 18 in, which sits comfortably under USPS's 130 in length-plus-girth ceiling, but it weighed 72 lb packed, 2 lb over the 70 lb line Ground Advantage draws. UPS and FedEx both quote heavier parcels, so the box still shipped without touching a freight quote.
Ground, not speed. On the 72 lb tool chest, UPS Ground returned the lowest quote at $111.86, well under half of UPS 2nd Day Air A.M.'s $254.62 for the same box. Weigh the item packed, not empty, before listing it, because a box this heavy prices the label more than the distance does.
