Where it comes from
A throw-up is the graffiti equivalent of a signature at scale. It takes one outline and one fill and nothing else, and it exists because writers needed something that could be finished in seconds on a surface they were not supposed to be near.
The blockbuster is the same instinct pushed toward block letters: wide, squared-off strokes with the letters almost touching, designed to be read from across the street or from a moving train. Historically both were styles for limited paint and limited time, and that constraint is exactly why they still look strong — with this much simplicity there is nowhere to hide a weak letter shape.
How it is built
Decide the total width before you draw anything
Throw-ups are usually two or three letters in one continuous silhouette. The width of the whole word is the design decision; the individual letters follow from it.
Draw the outline as one shape
Not three letters that happen to touch. The outline should be a single closed path, which is what gives the style its speed and its solidity.
Fill flat, then add one detail
The fill is one pass of one colour. The single detail is optional and it is usually where the can was fastest — the inside of an O, a shadow, a highlight along one edge.
Check it at a squint
A throw-up is working when you can read it with your eyes half closed from ten metres away. If the squint turns it into a shape, the letterforms are too complicated.
Terms you will meet
- Throw-up
- A quick, two-colour piece: one outline plus one fill. Often abbreviated to "throwie".
- Blockbuster
- A throw-up using squared-off block letters, sized for maximum coverage and distance legibility.
- Fill
- The colour inside the outline. In throw-ups it is applied in one flat pass.
- Outline
- The single line that defines the whole word. In throw-ups there is exactly one.
- Tag
- The handwritten signature, as opposed to the throw-up. Same writer, different tool.
Where it goes wrong
- Too much gap between letters — A throw-up with air between the letters stops reading as one piece and becomes three separate letters that happen to be near each other.
- Too little gap — The opposite failure. The outlines merge and at distance the whole word reads as a single blob with no interior structure.
- Adding a second fill colour — The moment a throw-up has two fills it is a piece, not a throw-up, and the speed advantage is gone.
- Ignoring the counters — In a blockbuster the counters — the holes in O, D, P, R, B — are what keep the letters legible at distance. A blockbuster with closed counters is a rectangle.

Three of the fifteen styles in the studio belong to this family. Each is a different skeleton of the alphabet, so the same word resolves differently in each one.
