Clay particles. Less than 2 micrometres in diameter.
The main criterion for classifying detrital sedimentary rocks is the grain size of the particles they are composed of. Detrital sedimentary rocks are classified based on the size of the sediment particles, including categories such as conglomerate, sandstone, siltstone, and shale.
Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.

Detrital rocks are sedimentary rocks that are composed of particles of weathered and eroded igneous, metamorphic, or other sedimentary rocks that have been deposited, compacted, and cemented together. Sandstone, conglomerate, shale, and breccia are examples of detrital sedimentary rocks.
Detrital rocks form from the accumulation and cementation of sediment grains derived from the weathering and erosion of pre-existing rocks. The size, shape, and composition of the sediment grains help to identify the environment in which the detrital rock formed. Detrital rocks include sandstone, shale, and conglomerate.

Shale is a sedimentary rock that typically has the smallest grain size due to its fine-grained and compacted nature.
The smallest thing you could imagine - a dust grain, a molecule, an atom, a quark.
the size of a grain of rice
Not even close.
the grain of zircon and it is the width of a human hair
Scientists believe that atoms are the smallest things on Earth, but they are not positive if this is entirely true. Years ago people thought a grain of and was the smallest.
