5 mm is the official definition. The fragments are broken down from larger plastic debris, are not visible in water and will either float or sink depending on what they are made of. That is 99% of the plastics found in marine environments or waterways.

Microplastics are 5 mm or less.

Think small, very thin strands of individual clothing thread that is in your household dust. It is long, but super thin.
