Microscopy is an excellent tool for determining particle size and shape. Although there are much faster and more precise analytical techniques for measuring particle size, microscopy does have some particular advantages in size measurements. Microscopy is the only method that can yield qualitative and quantitative estimates of particle shape. This chapter is dedicated to the subject of size and shape measurements using the microscope.
