Members of the platform have expressed outrage after an update resulted in listings displaying inaccurate size information.
The popular resale platform has updated its sizing categories for women's and children's clothes failing to inform all shoppers about the modification.
Countless users and merchants are expressing on platforms stating that platform listings now display an altered size classification compared to what was initially listed due to the recalibration.
The company said the revised method more closely matches comparable marketplaces.
They have suggested members to examine their items and update the measurements by hand when needed, resulting in member annoyance.
Previously, the sizes had both one number and one letter, such as S/8 or M/10.
The updated approach includes an alphabetical indicator and numerical range for example S/UK 8-10.
In some cases, the size labels have been reassigned - such as a large size used to be a 12 but is now a UK 16-18.
One content creator, who makes TikTok content about plus-size fashion, explained the modification "makes transactions more difficult".
"Rarely do manufacturers list XL as sizes 20-22," as the platform currently indicates.
Stephanie Gallen, located in Scotland, stated items she posted with size 14 tags were displaying on the service as measurements 20-22.
"If anyone [who is] size 20-22 buys them they will likely be quite upset," she said.
A different user, located in England, explained she became annoyed because the modification necessitated personal updates the sizes on "every single listing".
"This situation is especially annoying, because of my ongoing medical condition and selling on Vinted has been paramount following partial earnings loss," she explained.
The service features exceeding 100 million users, including 18 million in the UK.
It has become a favored option versus similar marketplaces including eBay and Depop.
This represents another occasion when a surprising modification on the platform has faced criticism: previously, the service retracted a modification concerning shipment methods following member complaints.
