sedimentry rocks can vary depending of the rock. But most sedimentry are between 12-100cm
Your question makes little sense, "a sedimentary rock" can be of virtually any size.
Sedimentary rocks are solid and can break into bit (rocks) of various sizes. However, if you mean what are the sizes of a "clast" in a clastic sedimentary rock then the answer is the same. A "clast" is a fragment of rock that is included in a new forming sedimentary rock - the term "clast" does not imply a size and indeed in a clastic sedimentary rock the clasts are frequently of many sizes.

The Wentworth scale of grain size measures the average diameter of particles in sedimentary rocks, ranging from clay (less than 0.002 mm) to boulders (more than 256 mm). It helps geologists classify sedimentary rocks based on the size of the particles they are composed of.
The general term for a rock fragment is a sedimentary rock. This is taught in science.
