This means that you will probably want to consider what maximum size of aggregate is best for the effect you want to achieve. Pea gravel (3/8-inch maximum) is a popular size for the purpose. It is often helpful to use a single size of coarse aggregate (1/4 to 3/8 inch, or 3/8 to 3/4 inch, for example) rather than a graded aggregate.
