UPS Shipping: Rates, Size Limits, Overnight & Pallet Tips for 2025
If you’re sending a box, a pallet, or even a 5 lb parcel, you’ve probably wondered how UPS figures the price and what it will actually accept. The good news is that UPS keeps its rules pretty clear, and the cost differences between a small package and a larger freight shipment are mostly about weight, size, and service level. Below you’ll find the basics you need to ship with confidence, plus a few shortcuts to keep your bill low.
How UPS Calculates Shipping Costs
UPS looks at three main factors: weight, distance, and the speed you choose. A 5 lb package traveling from London to Manchester will cost less than the same box going to Edinburgh because the mileage is shorter. If you pick UPS Ground, you’ll pay the lowest price, while UPS Express or UPS Next Day add a premium for speed.
For small shipments, UPS uses a “dimensional weight” formula. That means they compare the actual weight to the space the box occupies. If a light but bulky box takes up a lot of room, UPS will charge you based on the larger dimensional weight. The formula is simple: (Length × Width × Height) ÷ 139 (in inches) for U.S. shipments, or the local divisor for UK parcels.
When you’re figuring out the cost, plug the numbers into UPS’s online calculator or ask your removal company to run a quick quote. Most of the time, adding a few extra ounces or a couple of inches won’t change the price much, but crossing a weight or size threshold can add a big jump.
UPS Package Size & Pallet Shipping Rules
UPS has clear limits on what it will accept. A standard UPS package can’t exceed 150 lb (68 kg) and must fit within 108 inches (length + girth). The girth is measured as the distance around the thickest part of the box. If your package is larger than those limits, you’ll need UPS Freight, which handles pallets and oversized items.
Shipping a pallet with UPS is pretty straightforward. UPS accepts standard pallets up to 48 × 40 inches, and the pallet can weigh up to 1,500 lb (680 kg). You’ll need to secure the load with stretch wrap and make sure the pallet height stays under 72 inches. For heavier or taller pallets, UPS Freight will arrange a truck‑type delivery.
One handy tip for pallet shippers: pack the heaviest items at the base and avoid over‑hang. UPS will reject pallets that are unbalanced or have loose items. A well‑packed pallet not only passes inspection but also reduces the risk of damage during transit.
What about overnight shipments? UPS Overnight is generally reliable, but the cutoff times vary by location. In most UK cities, you need to drop off your package before 5 pm for next‑day delivery. If you’re sending a large pallet, you’ll usually have to schedule a freight pickup the day before.
To keep costs down, consider consolidating several small boxes into one larger package, or use UPS Ground for non‑urgent items. Ground rates are usually 30‑40 % cheaper than Express services, and the delivery window is still reasonable for many businesses.
Finally, remember that UPS offers extra services like insurance, signature confirmation, and Saturday delivery. These add to the price, so only pick what you truly need. If you’re shipping high‑value items, insurance is worth the cost; otherwise, you can save a few pounds by skipping optional add‑ons.
With these basics in mind, you’ll be able to choose the right UPS service, pack correctly, and avoid surprise fees. Whether you’re sending a 5 lb parcel, a bulky box, or a full pallet, the key is to know the size limits, understand how weight is calculated, and pick the service level that matches your timeline and budget.
