How to Ship an Oversized Package

How to measure length + girth (and why it decides everything)

Every oversize rule on this page is written in terms of length + girth, so get the measurement right before you compare anything. Length is the longest side. Girth is 2× width + 2× height, measured around the package at its thickest point. Add the two together.

Worked example: a box that is 40 inches long, 20 inches wide and 20 inches tall has a length + girth of 40 + (2×20 + 2×20) = 120 inches. That sits inside the parcel carriers' hard caps but is already well past the 96-inch threshold where UPS and FedEx start applying their Large Package Surcharge.

Additional handling and oversize surcharges

Long before a package hits the hard limits, it starts collecting surcharges. UPS and FedEx both apply an Additional Handling charge when the longest side exceeds 48 inches or the second-longest side exceeds 30 inches, and again on weight alone once a package passes 50 lbs. These stack on top of the Large Package and oversize surcharges covered in the steps above.

Which carrier suits which oversized package

• UPS Ground: accepts up to 150 lbs and 165 in combined length + girth. Best rates for packages 20–70 lbs once third-party discounts are applied.
• FedEx Ground: same size limits as UPS. FedEx Home Delivery serves residential addresses and is often slightly cheaper for deliveries to homes.
• USPS Parcel Select: accepts up to 70 lbs. Cheapest for packages under 20 lbs, but the 70 lb cap rules it out for most genuinely heavy items.
• DHL Express: up to 150 lbs; anything larger moves to DHL Freight.

Parcel vs LTL freight: where the crossover actually is

LTL (Less-Than-Truckload) freight handles 150–15,000 lb shipments — pallets, large equipment, furniture. Common LTL carriers are R+L, XPO Logistics, SAIA, ABF, YRC, Old Dominion, Estes, FedEx Freight and UPS Freight.

The tradeoff for the lower rate is time and logistics: LTL transit is typically 3–7 days versus 1–3 days for parcel, and pickup and delivery both need arranging rather than just handing a box to a driver.

• Parcel (150 lb box): $100–200 via UPS/FedEx Ground
• LTL (single pallet, 150–1,000 lb): $150–400 depending on distance and freight class
• For single items over 150 lb, LTL is often cheaper once oversize surcharges are counted
• Multi-pallet shipments: LTL wins dramatically

Freight class (NMFC) and how it sets your LTL rate

LTL rates depend on freight class — NMFC codes that classify commodities by density, stowability, handling and liability. Higher class means a higher rate. Dense, stowable items such as boxed goods fall into low classes; bulky, fragile or hazardous items fall into high ones.

Misclassifying a shipment does not save money — the carrier reweighs and reclassifies it, and you get an invoice adjustment after delivery. Run your dimensions and weight through a freight class calculator before you book.

• Class 50: dense, durable items (e.g. bricks)
• Class 85–92: standard consumer goods
• Class 150–175: bulky but dense (appliances)
• Class 250–400: very bulky or fragile (furniture, electronics)

Accessorial charges that inflate an LTL quote

The headline LTL rate covers dock-to-dock movement and nothing else. Everything a residential delivery actually needs is billed as an accessorial, and these are the reason a $200 quote becomes a $400 invoice:

• Residential delivery: +$50–150
• Lift-gate delivery (no loading dock): +$50–100
• Inside delivery (not just curbside): +$75–150
• Appointment delivery (time-specific): +$25–50
• Reconsignment (rerouting mid-transit): +$75–150

Getting an LTL quote without an existing carrier account

Quoting freight is a five-step exercise, and the last step is where most first-time freight shippers lose money by comparing base rates instead of totals:

1. Measure: dimensions (L × W × H) and total weight, including the pallet
2. Determine the freight class (NMFC) for what you are shipping
3. Get quotes from 3+ carriers: R+L, XPO, Old Dominion, FedEx Freight, UPS Freight
4. Compare the total including fuel surcharge and any residential or lift-gate accessorials — not the base rate
5. Book with the cheapest option you also trust on transit time

Freight brokers, if you ship oversized rarely

If freight is an occasional event rather than a routine, a broker is usually the faster route. uShip, Freightos and Freightquote.com aggregate LTL carrier quotes, compare multiple carriers instantly, and book on your behalf — useful when you have no LTL carrier relationships to leverage and no reason to build them.

Packing an oversized item so it survives the trip

Large packages are more likely to be damaged than small ones: they are harder to handle, pass through more sorting equipment, and are more likely to have other freight stacked on them. Use double-wall corrugated rated for the package weight — a burst strength of at least 275 psi for anything over 30 lbs — and reinforce every seam with 2-inch pressure-sensitive tape in an H-pattern.

For a fragile large item, suspend the product in the centre of the box using foam inserts so there is at least 2 inches of cushioning on all six sides. The finished box should be solid enough that you could drop it from 3 feet without the product shifting. Foam-in-place or custom moulded foam beats packing peanuts here, because peanuts migrate in transit and leave the item resting against a wall by the time it arrives.

• Palletize anything over 150 lbs — standard 48×40 inch wood or plastic pallets
• Stretch-wrap the palletized load tightly, then add corner protection
• Bolt down or strap heavy items to the pallet so nothing shifts in transit
• Secure loose components separately rather than letting them move inside the load
• For very fragile items, use a wooden crate rather than cardboard
• Include 3–4 inches of padding on all sides for heavy items, with the weight low in the box and lighter padding on top

Cutting the cost of an oversized shipment

DIM weight is the single biggest lever. A box measuring 24 × 18 × 12 inches has a dimensional weight of 5,184 ÷ 139 = 37.3 lbs with UPS or FedEx — so even a 10 lb item in that box is billed at 37 lbs. Every inch of unnecessary box adds cost.

• Minimize box size: use a box that fits the item with just enough padding and no extra empty space
• Disassemble when possible: ship furniture and equipment flat in a smaller box with assembly instructions
• Use third-party rates: platforms such as Pirate Ship and ShippingLabel offer discounted UPS and FedEx rates that can run 30–50% below retail
• Switch to freight for items over 150 lbs or very large dimensions, where LTL often beats parcel with surcharges
• Ship from home: both UPS and FedEx offer free daily pickups for account holders, which saves the trip as well as the fuel
