Above a certain size and weight, parcel services stop being the right tool — here is where the line sits and what to do on each side of it.
People assume heavy parcels are a weight problem, and often they are not. Carriers apply three separate limits: maximum weight per parcel, maximum length of the longest side, and maximum girth — the length plus twice the width plus twice the height. A 12 kg surfboard can be refused while a 30 kg box of tiles sails through, because the surfboard breaks the length limit.
Those limits also vary by service. Economy and road-based services frequently cap lower than express services, and the same carrier can accept a parcel on one product and refuse it on another. Above the parcel ceiling — commonly around 70 kg for a single piece on express networks — you move into pallet and freight territory, which is a genuinely different product with different pricing logic.
Heavy items are the ones where guessing costs most, because oversize and overweight surcharges are applied per parcel and can be substantial. Measure the sealed package including any crating or pallet base.
Length is the limit most often breached. Long, thin items — skis, rugs, curtain poles, furniture parts — hit it well before their weight becomes relevant.
Girth is length plus twice the width plus twice the height. Bulky cube-shaped items breach girth limits even when each individual dimension looks acceptable.
Under the parcel ceiling and within dimensional limits, use a parcel service. Above it, or for multiple heavy pieces, palletised freight is usually cheaper per kilo as well as more practical.
Double-wall cardboard for heavier parcels, triple-wall or a wooden crate above roughly 30 kg. A box that fails under its own contents in transit is not a packing inconvenience — it is a total loss.
Most parcel shops will not accept heavy or oversized items, and carrying them is a genuine injury risk. Collection is the practical route above about 20 kg.
| Situation | Right service | Why |
|---|---|---|
| Single item under about 30 kg, normal dimensions | Standard parcel service | Fits every carrier's limits, widest choice and best price |
| Single item roughly 30–70 kg | Heavy parcel service | Still parcel-network, but expect surcharges and collection-only handling |
| Long items over about 1.5 m | Specialist or freight service | Length limits bite well before weight does |
| Several heavy items to one address | Palletised freight | One pallet is usually cheaper than many heavy parcels |
| Anything above about 70 kg as one piece | Freight | Beyond the parcel network's handling capability |
| Bulky but light — furniture, foam, packaging | Freight or pallet | Volumetric weight makes parcel pricing uneconomic |
Assuming only weight matters — length and girth limits refuse more parcels than weight does.
Booking a standard service for an oversized item, which triggers surcharges or an outright refusal at the depot.
Trying to drop off a heavy parcel at a shop that cannot accept it, wasting the trip.
Using single-wall cardboard for a dense load, which fails under compression in a stacked cage.
Splitting a heavy shipment into many parcels without checking whether one pallet would be cheaper.
Forgetting that a wooden crate's own weight and dimensions count toward the limits.
Not warning the recipient that a heavy delivery is coming and may need help or equipment to receive.

Above the parcel ceiling you move to palletised freight, which is usually both cheaper per kilo and more practical for the handlers.
Any parcel breaching a service's limit on the longest side, on girth (length plus twice the width plus twice the height), or on weight. Long thin items breach length limits well before weight becomes an issue, which is why skis, rugs and furniture parts so often need a specialist service.
It depends where the thresholds fall. Splitting avoids oversize surcharges but adds a base charge per parcel, so several parcels are not automatically cheaper. Compare both, and if the total is genuinely heavy, price a pallet alongside them — it frequently wins.
Usually not. Parcel shops have their own weight and size limits, typically well below the carrier's maximum, and shop staff are not equipped to handle heavy items. Book a collection for anything above roughly 20 kg.
If your shipment is above the parcel ceiling as a single piece, or consists of several heavy items going to one address, a pallet is usually both cheaper and safer. It also means the whole consignment is handled mechanically rather than manually, which reduces damage risk.
