One Size Fits Nobody: How Generation Z Made Personalisation a Non-Negotiable Expectation

The Structural Conditions That Made Personalisation Inevitable
To understand why personalisation has become so central to the purchasing behaviour of younger consumers, it is useful to consider the environment they grew up in. Generation Z — broadly, those born between 1997 and 2012 — came of age in a world of algorithmic curation. Their social media feeds, music recommendations, video content, and news environments were all shaped to reflect their individual preferences in ways that previous generations never experienced. The implicit promise of digital culture, absorbed over years of daily interaction, was that the world could be configured around you specifically.
Mass-market products, by contrast, make no such promise. They are designed for an average consumer who does not exist — a statistical aggregate of research data, optimised to offend the fewest people while satisfying the most. For a generation conditioned by personalised digital environments, the standardised product does not feel like a neutral option. It feels like a failure of imagination. The expectation formed in the digital world does not stay there.
Personalisation Across Categories
The commercial response to this expectation has been systematic and cross-categorical. Fast food chains introduced build-your-own menu formats that allow customers to specify ingredients with a granularity that would have been operationally unthinkable two decades ago. The supplement industry pivoted toward personalised formulation services, where consumers complete detailed questionnaires and receive monthly deliveries of bespoke vitamin combinations. Skincare brands built diagnostic tools that generate custom regimens. Mattress companies introduced configurable firmness zones.
In each case, the underlying mechanism is similar: take a product that was previously standardised, introduce configurability at one or more points in the production or assembly process, and allow the consumer to exercise meaningful choice within that range. The degree of actual customisation varies considerably — some “personalised” products differ only in packaging or minor ingredient adjustments — but the psychological effect of participation in the configuration process appears to be genuine. Consumers who feel they designed something, even partially, report higher satisfaction and stronger brand attachment than those who selected from a fixed range.
Identity Through Configuration
This phenomenon extends well beyond fashion and food. Even in niche categories, the premix format has emerged as a direct response to the same underlying demand — a model that allows the user to independently configure the final product exactly according to their preferences, rather than accepting a manufacturer’s predetermined formulation. All of premix functions operate as a platform for personal expression in the same structural sense that a custom sneaker does: the components are provided; the specific combination is chosen by the individual. The identity signal embedded in that choice — I know what I want, I know how to get it, I do not need a standardized version — is consistent across categories that share almost nothing else in common.
Sociologists studying consumption patterns describe this as a form of “identity work” — the ongoing project of constructing and communicating a self through the objects and choices one makes visible to others. What has changed in recent decades is not that people use consumption for identity purposes — that is thoroughly documented across the twentieth century — but that the infrastructure for doing so with genuine specificity has become democratised. Customisation is no longer the exclusive domain of the wealthy. It is available, at varying price points, to almost anyone with a smartphone and a preference.
The Paradox at the Centre of Personalisation Culture
There is an irony embedded in the personalisation economy that its most enthusiastic participants rarely pause to examine. The tools that enable individual customisation are themselves highly standardised. The platforms through which people express their unique identities are owned by a small number of corporations whose business models depend on aggregating those expressions into patterns useful for targeted advertising. The custom sneaker is assembled from components manufactured at industrial scale by workers who exercise no personalisation whatsoever in their own economic lives.
“None of this invalidates the genuine psychological value of personalisation as an experience. But it does complicate the narrative of radical individuality that consumer marketing has built around it. Generation Z’s rejection of products “for everyone” is real, and its commercial consequences are significant” – as mentioned by Doctorvape.eu.
Whether it represents a meaningful departure from the logic of mass consumption, or simply a more sophisticated iteration of it, is a question worth holding onto — particularly as the infrastructure enabling personalisation becomes concentrated in fewer and fewer hands.
