What USPS and UPS Charge for a Sub-1 lb Package#

For a sub-1 lb package, USPS Ground Advantage is typically the cheapest option, from $5.27 in the app for a parcel up to 4 oz on the nearest zone (farther and rural destinations price higher). Heavier ounce tiers and farther zones price higher in the app, up to $8.23 for 13 to 15.999 oz to the farthest zone, still below the UPS Ground and Priority Mail figures in the table. Here's how all major carriers and services compare.

Common Items That Weigh Sub-1 lb#

Items that typically weigh around sub-1 lb include:

• Greeting cards and stationery
• Folded T-shirts and soft apparel
• Phone cases and small accessories
• Jewelry and enamel pins
• Paperback books and zines
• Cosmetics samples and small tins

Packing a Sub-1 lb Package Without a Dimensional-Weight Charge#

1. 1

   Check whether the item is letter-eligible before you print a parcel label. A flat, bendable piece under 3.5 oz that fits letter dimensions (about 11.5 by 6.125 by 0.25 in) can mail for $0.82 in stamps at 1 oz, up to $1.69 at 3.5 oz, instead of a Ground Advantage parcel, which starts at $5.27 with I'd Ship That. That letter-versus-parcel gap is the biggest single saving under a pound.

2. 2

   Ounce discipline moved, it did not die. Buying raw commercial the sub-pound price is flat by zone, so a 4 oz parcel and a 15.999 oz parcel cost the same there. But the displayed Ground Advantage rate in I'd Ship That still steps down by ounce tier, from $5.27 under 4 oz, so a lighter mailer still buys a lower tier in the app.

3. 3

   Guard the 15.999 oz line. At 16.0 oz the parcel leaves sub-pound pricing and rounds into the 1 lb band, where commercial Ground Advantage runs about $8.01 to $11.22 by zone and the displayed rate in the app runs from about $6.60, so a trimmed insert that keeps a borderline order at or under 15.999 oz still pays off at the counter and on zones 6 to 8; in the app on zones 1 to 5 a box just over a pound bills at the 2 lb row and can price below the 13-15.999 oz tier ($5.78 against $6.54 in zone 1).

4. 4

   Know your zones, because zone swings the price under a pound. The same parcel can move from about $7.33 near you to about $8.95 across the country buying commercial, and the displayed rate in the app scales by zone too, so zone is a major lever alongside the ounce tier.

5. 5

   Keep letter-eligible mail machinable. A rigid or lumpy piece that would otherwise qualify as a letter can trigger the $0.49 nonmachinable surcharge, so keep flats flat and bendable to hold the stamp price.

Money left on the table

Where Sub-1 lb Shippers Leave Money on the Table#

• USPS Ground Advantage absorbed First-Class Package Service in 2023. If a tool or old workflow still says First Class Package, Ground Advantage is the current parcel service and the rate to quote under a pound.
• The July 12, 2026 USPS restructure flattened the sub-pound commercial tiers. Any saved quote or calculator still showing the published commercial Ground Advantage parcel rate below $7.33 is stale (negotiated and discounted rates can run lower); commercial parcel pricing now starts at about $7.33 and is set by zone, while the displayed rate in the app starts at $5.27 and still steps by ounce tier.
• Rate-shop USPS against UPS even at these small weights. USPS is the sub-pound parcel default: UPS Ground has no ounce pricing, bills at least 1 lb ($11.99 to $15.03 on its published daily rate), and adds a $6.50 residential surcharge, so on published rates it does not beat commercial Ground Advantage on any zone. The app discounts UPS labels too, so the comparison still runs on every order. Rate-shopping pays at every weight, not just this one: a 4 lb box to zone 4 can even price below a 1 lb one in the app, so quote the real lane rather than assuming a heavier or nearer parcel costs more.
• The retail-to-commercial Ground Advantage gap under a pound runs $0.94 to $4.70 by tier and zone, and the displayed rate in the app sits below commercial, from $5.27, so you get a lower price and the service-choice savings. The biggest lever is still service choice: routing a letter-eligible piece as a letter saves more than any tier step does, and holding a borderline order under 1 lb pays at the counter and on the far zones.
• Shipping many sub-pound orders? The Workbench (Pro) bulk imports, rate-shops, and batch-prints, and Ship Intelligence auto-picks the cheapest valid rate on every label so you are not choosing a service order by order.

Shipping a Sub-1 lb Package: Key Takeaways#

• Buying raw commercial, sub-pound Ground Advantage is set by zone alone (4 oz and 15.999 oz cost the same, roughly $7.33 to $8.95); through I'd Ship That the displayed rate still steps down by ounce, from $5.27 under 4 oz.
• The ounce ladder flattened at the counter but is alive in the app: the displayed Ground Advantage rate steps down by tier, so ounce discipline still pays in I'd Ship That even though it no longer does buying raw commercial.
• The biggest saving under a pound is the letter-versus-parcel line: a flat, bendable item up to 3.5 oz can mail for $0.82 to $1.69 in stamps instead of a parcel that starts at $5.27 in the app.
• The main weight cliff is 15.999 oz to 1 lb: crossing it rounds a parcel into the 1 lb band, about $8.01 to $11.22 commercial by zone and from about $6.60 displayed in the app. In the app the cliff holds on zones 6 to 8; on zones 1 to 5 a parcel just over a pound bills at the 2 lb row, from $5.78, below the $6.54 top sub-pound tier.
• Ground Advantage is the current sub-pound parcel service (it absorbed First-Class Package in 2023); rate-shop it against UPS, but USPS usually wins here.

The Sub-1 lb Ounce Ladder Flattened at the Counter, Not in the App#

For years the rule under a pound was simple: watch the ounces, because the price stepped at 4, 8, 12, and 15.999 oz. When USPS restructured Ground Advantage on July 12, 2026, it flattened those sub-pound tiers for raw commercial pricing, so a 4 oz parcel and a 15.999 oz parcel now cost the same commercial rate to the same zone, roughly $7.33 near you rising to about $8.95 at the far zones.

Buying commercial, the lever moved from the scale to the map: what changes that bill is where the parcel is going, not how many ounces it reads. Through I'd Ship That the ladder is still there. The displayed Ground Advantage rate steps down by ounce tier, from $5.27 under 4 oz, so a lighter mailer still earns a lower tier in the app. Ounce discipline is dead at the counter and alive in the app.

USPS Ground Advantage under a pound, zone 1

$5.27$5.68$6.10$6.54$7.33

3. Up to 12 oz$6.10
4. Up to 15.999 oz$6.54

1. USPS commercial (published), up to 15.999 oz$7.33

Weight is not irrelevant, but where it bites depends on how you buy. On raw commercial the money sits at two cliffs instead of four steps: the line between a letter and a parcel, and the line between 15.999 oz and 1 lb, with everything in between flat. In the app the ounce tier still moves the displayed price on top of those two cliffs, so trimming a parcel from 15 oz to 8 oz can drop it a tier. At the retail counter the old step around 12 oz still exists, but if you ship discounted you never touch it.

• Record the zones you ship to most; under a pound, zone sets the commercial rate and scales the displayed rate too.
• Trimming to a lighter ounce tier does nothing buying raw commercial, but it still lowers the displayed rate in the app, from $5.27 under 4 oz.
• Weigh the sealed parcel to confirm it stays at or under 15.999 oz and to land the right ounce tier in the app.
• Ignore dimensional-weight math on true sub-pound parcels unless the box exceeds one cubic foot (1,728 cubic inches).

The Two Cliffs That Still Move a Sub-1 lb Bill#

The biggest saving under a pound is not a lighter mailer, it is shipping the right class. A flat, bendable, machinable item under 3.5 oz that fits letter dimensions (about 11.5 by 6.125 by 0.25 in), a greeting card, a photo, a single sticker sheet, can mail as a First-Class Mail letter for $0.82 in stamps at 1 oz, up to $1.69 at 3.5 oz, instead of $5.27 or more as a Ground Advantage parcel in the app.

That is the largest gap in this whole weight class, and it got wider when parcel prices reset upward. Keep those pieces flat and bendable so they stay machinable; a rigid or lumpy letter can trigger the $0.49 nonmachinable surcharge and lose part of the advantage.

The second cliff is 15.999 oz. At 15.999 oz you are still in sub-pound pricing; at 16.0 oz the parcel rounds into the 1 lb band, where commercial Ground Advantage runs about $8.01 to $11.22 by zone and the displayed rate in the app runs from about $6.60.

If your orders naturally weigh 14 to 17 oz, this is the one line worth defending with a lighter mailer or a trimmed insert at the counter and on zones 6 to 8, because it is now the only weight step under a pound that changes the commercial price.

In the app on zones 1 to 5 the 17 oz order is the cheaper one: it bills at the 2 lb row, $5.78 in zone 1 against $6.54 for 14 oz. And do not step up to Priority Mail or Priority Mail Express unless a delivery date is a real requirement; at these weights the speed premium is well above the Ground Advantage rate for the same small parcel.

• Before printing a parcel label, check whether a flat item under 3.5 oz could mail as a letter for $0.82 to $1.69 instead.
• Keep letter-eligible pieces flat and bendable so they stay machinable and avoid the nonmachinable surcharge.
• Set a hard packing target at or under 15.999 oz for any SKU that naturally weighs 14 to 16 oz.
• Only choose Priority or Express when the delivery date is a genuine requirement, not a habit.

Making the Right Sub-1 lb Service the Default at Volume#

Choosing letter versus parcel, catching the parcel that quietly tipped over 1 lb, and landing each order in its lowest ounce tier is trivial for one order and relentless for two hundred. The leak is small per label but it repeats: a seller who prints a parcel label for an item that could have gone as a letter for $0.82 to $1.69, or who lets borderline orders drift over 1 lb, hands the carrier a few dollars on each one, which compounds across a week of shipping. The figures depend on your mix and zones, but the direction holds, and the July 2026 reset widened the gap on every retail label.

Two things close it. Shipping on the displayed rates in the app, below the retail counter and below commercial from $5.27 under 4 oz, lowers the base price, with the full price shown before you buy, and saves $2.72 to $6.60 at the Pro price versus the Post Office retail price on a sub-pound label, depending on ounce tier and zone.

Then, for shippers on Pro, Ship Intelligence automatically selects the cheapest valid rate and surfaces savings analytics, while The Workbench bulk imports, rate-shops, and prints a whole batch of labels in one pass. You start free and pay per label, so the workflow fits whether you print 50 sub-pound orders a week or 5,000.

• Audit your lightest, flattest SKUs to see which could ship as letters instead of parcels.
• Ship on the displayed rates in the app, below the retail counter, from $5.27 under 4 oz.
• Turn on Ship Intelligence so the cheapest valid rate is chosen automatically each time.
• Batch with The Workbench once you are printing more than a handful of labels at a sitting.

Common Mistakes When Shipping a Sub-1 lb Package#

Sub-1 lb Shipping Checklist#

• Audit your lightest, flattest SKUs and flag any that could mail as a letter for $0.82 to $1.69 instead of a parcel.
• Confirm letter candidates are flat, bendable, under 3.5 oz, and within letter dimensions so they stay machinable.
• Record the zones you ship to most, since zone sets the USPS commercial price and scales the displayed rate under a pound.
• Flag SKUs that pack at 14 to 17 oz and set a hard target to keep them at or under the 15.999 oz cliff.
• Keep light items in their lowest ounce tier; it does nothing buying raw commercial but still lowers the displayed rate in the app, from $5.27 under 4 oz.
• Default to USPS Ground Advantage for parcels, but quote it against UPS on your real zones.
• Only step up to Priority or Express when a delivery date is a genuine requirement.
• If you batch more than a handful at once, set up The Workbench to import, rate-shop, and print in one pass.

Sub-1 lb Shipping: Questions People Ask#

How much does it cost to ship a package under 1 pound?

With I'd Ship That the displayed Ground Advantage rate starts at $5.27 under 4 oz and steps up by ounce tier and zone. Buying raw commercial, the sub-pound price is flat by zone, roughly $7.33 to $8.95, with 4 oz and 15.999 oz costing the same to a given zone. At the retail counter the price is higher and still steps up around 12 oz, roughly $8.40 to $13.65. Priority Mail starts around $9.44 commercial for 2-3 day speed. You see the full price before you buy on I'd Ship That.

What is the cheapest way to ship a package under 1 pound?

USPS Ground Advantage is the cheapest way to ship a package under 1 pound: from $5.27 with I'd Ship That (Pro price), or roughly $7.33 to $8.95 at USPS commercial rates depending on zone. A flat, bendable item that fits letter dimensions is cheaper still as a letter, $0.82 in stamps at 1 oz and $1.69 at 3.5 oz. UPS Ground bills at least 1 lb, $11.99 to $15.03 on its published daily rate, so on published rates it does not beat commercial Ground Advantage on any zone.

What are the USPS ounce breakpoints under a pound?

It depends where you buy. Buying raw commercial they no longer move the price: USPS flattened the sub-pound tiers on July 12, 2026, so a 4 oz, 8 oz, 12 oz, and 15.999 oz parcel all cost the same commercial rate to a given zone. But through I'd Ship That the displayed Ground Advantage rate still steps down by ounce tier, from $5.27 under 4 oz, so a lighter mailer still earns a lower tier in the app. The retail counter also still steps up around 12 oz. The one weight line that changes the commercial price is 15.999 oz, where the parcel crosses into the 1 lb band; in the app on zones 1 to 5 a parcel just over a pound bills at the 2 lb row and can cost less than the top sub-pound tier.

Does dimensional weight matter under a pound?

Almost never on USPS. Ground Advantage only assesses dimensional weight once a parcel exceeds one cubic foot (1,728 cubic inches), and almost nothing that weighs under a pound is that large. Under a pound the price is set by zone and, in the app, by ounce tier, so weigh the sealed parcel mainly to land the right ounce tier and to see which side of the pound line it falls on, and focus on zone and whether the item could ship as a letter instead.

Can I still save by shipping a lighter package under a pound?

It depends where you buy. Buying raw commercial, no: sub-pound commercial pricing is flat by zone, so trimming a 15 oz parcel to 8 oz does not lower the commercial label. But through I'd Ship That the displayed Ground Advantage rate still steps down by ounce tier, from $5.27 under 4 oz, so a lighter mailer does buy a lower tier in the app. One thing saves everywhere: routing a flat, bendable, letter-eligible item up to 3.5 oz as a letter, $0.82 in stamps at 1 oz and $1.69 at 3.5 oz, instead of a parcel. Keeping a borderline order at or under 15.999 oz saves at the counter and on zones 6 to 8, while in the app on zones 1 to 5 a parcel just over a pound bills at the 2 lb row and can cost less.

Is USPS or UPS cheaper under a pound?

USPS is cheaper at sub-pound weights. Ground Advantage displayed rates in the app start at $5.27 and commercial parcels run $7.33 to $8.95, while UPS Ground has no true sub-pound pricing: it bills at least 1 lb, $11.99 to $15.03 on its published daily rate across zones 2 to 8, and adds a $6.50 residential surcharge USPS does not. On published rates UPS does not beat commercial Ground Advantage on any zone under a pound, so for everyday under-1-lb parcels USPS is the default; rate-shop both anyway, since the app discounts UPS labels too.

What happens if my package hits exactly 16 ounces?

At 16.0 oz the parcel leaves sub-pound pricing and rounds up into the 1 lb pound band, where commercial Ground Advantage runs about $8.01 to $11.22 by zone and the displayed rate in the app runs from about $6.60. That step is the main weight cliff at the commercial counter, since the ounce tiers below it are flat there; in the app it bites on zones 6 to 8, while on zones 1 to 5 a parcel past 16 oz bills at the 2 lb row and can price below the 13-15.999 oz tier. If your orders cluster at 15 to 17 oz, a lighter mailer or a trimmed insert that keeps you at or under 15.999 oz still pays for itself on the first label.

Did sub-pound shipping rates go up in 2026?

Yes, and they were restructured. USPS raised and reworked Ground Advantage on July 12, 2026, which flattened the sub-pound commercial ounce tiers and erased the old sub-$6 parcel rates. Commercial sub-pound parcels now run about $7.33 to $8.95 by zone, while displayed rates in the app start at $5.27. Buying raw commercial, keep costs down through service choice and staying under 1 lb; in the app the displayed rate also steps down by ounce tier, so a lighter mailer still helps there.
