Rake the field. This will level out clumps or anything else that might disrupt the chalk. You can use an infield drag to smooth out especially rough patches.
Measure between the bases. The distance from home plate to second base should be 127 feet, 3 3/8 inches, and the distance from home plate to first and third base should be 90 feet. The distance between second base and both first and third base should also be 90 feet exactly. The pitching rubber should be 60 feet, 6 inches from home plate.
Set up the chalk marker. The marker is on wheels, and the chalk is placed inside the container above the wheels. As you roll the marker, an even, solid 2-inch line is laid down. The chalk marker might need to be refilled three times while chalking the field. The field should be dry when the chalk is applied.
Chalk the line from the front corner of home plate and first base. This line should be a straight line and runs from home plate to the outfield, along the perimeter of the outfield. You can use about a 500-foot piece of twine to keep the line straight. Stick pegs at the corner of the infield and outfields, and run the twine through the pegs. Use this as a guide to create an accurate chalk line, if necessary.
Chalk the batter’s box, which is 4 feet wide, 6 feet long, around home plate. A "batter's box" template (available for under $100) can make this a much quicker task.
