Graffiti and street art share walls, materials and sometimes the same artists. That does not make them interchangeable. The most useful distinction begins with what a work is doing, who it speaks to and the culture it comes from.
Here, graffiti means the tradition of style writing: names, signatures and letterforms developed through a writer’s individual approach. Street art is a broader, debated label often applied to images, stencils, pasted works and interventions that address people in public space. Neither description accounts for every work.
Graffiti starts with a name
In style writing, a chosen name becomes something to build, repeat and recognise. A tag can make that name visible through a few strokes. A throw-up gives it a larger silhouette. A piece develops the letters through structure, colour and detail. The vocabulary documented by Art Crimes helps distinguish these forms.
Knowing the name is only the beginning. Other writers may recognise a particular connection between letters, a familiar outline or a change in someone’s handstyle. Reading graffiti can therefore involve knowledge that is not immediately available to a passer-by. That does not make it meaningless; it means there is more to learn.
Street art has no single visual formula
A stencil, a pasted portrait and a sculptural intervention can look unrelated while being discussed under the same label. Street art often offers an image or proposition that a broad audience can approach without first learning a writer’s name or lettering conventions.
Institutions draw the boundary differently. AMUSEUM, for example, places particular emphasis on social criticism and intention when defining street art. That is a specific curatorial position, rather than a universal test. A useful discussion makes its definition clear instead of assuming everyone uses the term in the same way.
Permission does not settle the distinction
Calling graffiti illegal and street art legal produces a misleading shortcut. Permission describes the circumstances of a work. It does not, by itself, explain its lettering, audience or relationship to a scene. A commissioned letter piece can still belong to a writer’s practice; an unauthorised image does not automatically become style writing.
The same applies to materials and scale. Spray paint is a tool, and a mural is a painting on a wall. Neither word tells you enough about the cultural tradition behind the work. A large, polished surface is not automatically more significant than a small signature.
Artists move across the boundary
Lady Pink is a useful example of why rigid categories can fail. Her own biography describes subway painting from 1979 to 1985, gallery exhibitions beginning while she was still at school, and a continuing practice involving canvases and mural workshops. Those settings are connected parts of a career, rather than evidence that one identity simply replaced another.

How we approach it at NastyVandal
We start with the writer or artist, the work and its context. What is being repeated? How are the letters or images constructed? Who is likely to recognise the references? What does the location contribute? These questions tell us more than deciding which side of a tidy divide a photograph belongs to.
