That should depend upon how wide your screen or window is. I have added code to betzaFlex.js to use more flexible values for the height and width of table cells in the diagram. Instead of assigning a single fixed value to height and width, it calculates the maximum value that will allow the whole board to remain visible in terms of viewport units and container units, and it uses the CSS min function to apply the minimum of these and the assigned value. So, if the viewport is wide enough, it will use the assigned value, and if it is not wide enough, it will use a smaller value that lets the whole board stay in view.
