The above graph shows possible sizes for tiles in scratch. x is the size of the square, y is the overall size of the grid. The 3 graph lines are as follows in bitmap view: 1. x is based on the white and grey boxes 2. x is based off of 1x1 pixel according to scratch, a 2x2 using the paintbrush 3. x is based off of a 1x1 according to the paintbrush To determine the exact number needed in each direction divide the y by 7, then multiply by 4 for the width and 3 for the hight
