Anthracite coal comes in a variety of sizes; certain stoves require a specific size of coal whereas other stoves may be able to burn a few different coal sizes. While there are more sizes of hard coal than those listed blow, these are the primary four sizes that will be used in most coal stoves. Rice 3/16" to 5/16".

There are four major types (or "ranks") of coal. Rank refers to steps in a slow, natural process called "coalification," during which buried plant matter changes into an ever denser, drier, more carbonrich, and harder material. The four ranks are: Anthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high ...
