Each recipe is unique. Look at the dough in your machine. As with scratch bread baking, the humidity and temperature of the day can affect your loaf performance. If your dough looks too wet add some more flour. Similarly if it looks to dry add a little more liquid.
Bread is characterized by height, color, crust and texture.
Each recipe is unique. A hearth bread may be lower in volume because it is denser and a white bread maybe taller with more open structure while a robust grain may have a thicker firmer crust. Your choice of recipe and the settings you choose on your machine can optimize the loaf you desire. There is no standard bread height. There are a variety of pan shapes and sizes that will determine the average height of a loaf.
