Most mural artists start with small sketches. But how do they translate that onto a large wall? New York street artist BK Foxx explains: “Painting a big wall is really the same as painting a small canvas, because proportions are still relative to each other. On a canvas, the increments of measure are inches; on a wall, it’s feet.”
BK, who has been spray-painting murals since 2013, often starts with a photograph of the actual wall to determine the dimensions for her template. She then takes a picture of the subject she wants to paint and uses Photoshop to superimpose it on the wall photo. Then she prints the image on an 8.5-by-11-inch paper for reference. Before painting, BK marks the center of the wall with a little cross. She then makes more marks to divide the wall into quarters, eighths, sixteenths, and so on. She marks up her printed image in the same way to keep perspective.
This method proved useful when she painted her biggest mural to date, which was 100 feet tall. “When I discovered I could make these really cool images that were so much bigger than myself, I just wanted to keep doing it,” says BK. “Even now, I want to paint bigger and bigger each time.”
