The whole point of drawing a grid is to break up the page into different size sections. Drawing a grid is a great icebreaker to a blank page. You can draw any of these with small spaces or very large spaces. Try both to see what you like. Play with drawing your grid with a light pencil, black ink, white paint or a color. You may want your choice to be waterproof just in case you want to paint near your lines or over them.
