We pack a coat sold on Vinted, we vaguely measure the box, and we rush to the local pickup point. And there, the merchant refuses the package: too wide by two centimeters. This scene repeats every week in thousands of partner shops. Knowing the dimensions of Mondial Relay packages before sealing the box avoids this kind of disappointment, whether selling on Vinted or Leboncoin.
Refusal at drop-off: why the merchant has the final say on your Mondial Relay package
Most sellers think that a successfully generated label guarantees package acceptance. This is false. The merchant at the pickup point can refuse a package on the spot, even if the label is valid, as soon as they deem the package oversized.
In practice, the relay operator scans the label, visually assesses the package, and decides. If the box exceeds the storage size allowed in their shop, they block the shipment. No contestation is possible at this stage.
To avoid an unnecessary round trip, we check the dimensions of Mondial Relay packages to respect before preparing the packaging. This check takes thirty seconds and saves half an hour of wasted travel.
The standard size accepted at a physical pickup point is around 60 x 40 x 20 cm for a maximum weight of 30 kg. Some shops with more generous storage space tolerate slightly larger sizes, but they are not obliged to. The refusal remains at the merchant’s discretion.
Locker or pickup point: the sizes are not the same
A common trap on Vinted and Leboncoin concerns the choice between a Mondial Relay locker and a traditional pickup point. The two do not share the same size constraints at all.
Physical limits of the locker
An automatic locker accepts packages that are significantly smaller than those at a partner shop. The typical size is limited to about 40 x 30 x 15 cm. Beyond that, the locker door simply won’t close.
For a seller, this means that a package perfectly compliant at a pickup point may get stuck if the recipient has chosen a locker. We have no control over this choice from the sender’s side: it is the buyer who selects their pickup method.
Adapt the packaging from the start
The most reliable strategy is to pack as tightly as possible. A folded garment in a soft plastic bag will fit in both a locker and a pickup point. An oversized rigid box, on the other hand, poses problems everywhere.
- For clothing and small accessories, prefer a soft pouch rather than a box, which reduces bulk by several centimeters in each dimension
- For shoes, remove the original box and use a fitted package if the buyer agrees (to be specified in the listing)
- For fragile items, choose a box just slightly larger than the item, with crumpled paper rather than bulky bubble wrap
Size thresholds for bulky shipments on Vinted and Leboncoin
Beyond a certain size, a package moves out of the standard category and into the “bulky” category. At Mondial Relay, the maximum length limit of 150 cm and a total perimeter (length + width + height) of 300 cm constitute the structuring threshold.
Exceeding these limits leads to different delivery solutions, with significantly higher rates. On Vinted, the transport options offered to the buyer depend directly on the weight and size declared by the seller in the listing. On Leboncoin, Mondial Relay home delivery accepts up to 25 kg.
How to measure your package correctly
Always measure the external dimensions of the package once closed, including tape and reinforcements. A box that is 59 cm wide can reach 61 cm once the flaps are folded and the tape is applied. These two centimeters are enough to trigger a refusal.
Using a tape measure rather than a visual estimate makes all the difference. Measure the length (the longest side), width, and height, then add the three to check that you stay under the allowed perimeter.
Minimum size for Mondial Relay packages: the forgotten criterion
Everyone focuses on the maximums, but Mondial Relay also imposes a minimum size below which a package will be refused. A small piece of jewelry shipped in a too-thin envelope or a keychain in a miniature bag may not pass the scan.
The reason is logistical: a package that is too small cannot properly receive the tracking label, and it risks getting lost on the sorting conveyors. On Vinted, returns vary on this point depending on the pickup points, but the basic rule is to never go below a size close to an A5 sheet in surface area.
Content restrictions and shipping conditions on Vinted and Leboncoin
Dimensions are not everything. Mondial Relay also applies restrictions on the content of packages, and some lead to refusals that sellers do not see coming.
- Liquids, lithium batteries, flammable materials, and sharp objects are excluded from the relay network, regardless of the package size
- Items of value beyond a certain amount (variable depending on the Vinted or Leboncoin contract) are not covered by transport insurance
- A poorly closed package or one that appears fragile may be refused at the scan by the merchant, even if it meets the size requirements
The tracking code generated by Vinted or Leboncoin only protects the seller if the package complies with the carrier’s conditions. In case of a dispute, an oversized shipment or one containing a prohibited item does not entitle the seller to any compensation.
Before each Mondial Relay shipment, the verification consists of three steps: measuring the closed package with a tape measure, weighing it on a scale (not by hand), and reviewing the content restrictions related to the platform used. These few minutes of preparation remain the safest way to avoid a package that comes back.
