What is a checkerboard pattern?
A checkerboard is a grid of squares in two alternating colors, so no two squares of one color share an edge. It is the board of checkers and chess, and one of the oldest check patterns in cloth, tile floors and racing flags.
Turned 45 degrees, the same squares stand on their points as diamonds, the look of a harlequin costume or a diagonal tile floor.
How to make a checkerboard background
Size sets one repeat, two squares across, from 6 to 600 pixels of a 1080p frame, so each square is half of it. Angle turns the board from 0 to 180 degrees; 45 gives diamonds.
Pick the two colors under Colours: black and white for a chessboard, two close tones for a quiet floor, or bright pairs for a racing look. The squares share exact edges, so there are no gaps or seams between them.
Can the checkerboard move?
Yes. Scroll slides the board along its own direction at that many repeats a second; the Checker preset starts still. Record the motion as MP4, WebM or GIF at 720p for up to 30 seconds.
A still saves as PNG, JPG or WebP up to 2048 px, handy as a backdrop, a placeholder texture or a transparency-style grid. It renders in your browser and nothing is uploaded.
