How to Paint a Floor

Setting a checker pattern on a diagonal looks dynamic and makes the room appear bigger. But the pattern will look best if it ends in perfect half-square triangles at the most visible walls. So figure out which wall is least visible and start measuring on the opposite side of the room. Keep in mind that the painter's tape outlines the box you're painting, so it will fall on alternating sides of the pattern's lines from square to square.

Estimate the number of squares you want to fit across the center wall of the three most visible walls. Divide the length of the wall by the number of squares. With this measurement, mark the wall from corner to corner.
