Note that nominal sizes are not always precisely equal to actual sizes.

So various standards have specified the difference between nominal size, and finished size, of lumber.

Its nominal size is neither the inside nor outside diameter.

Depending on what areas are included or excluded, the nominal size of the Thar can vary significantly.

Instead this document describes conductors by their nominal size.

However, classical statistical tests, including those based on the mean, are typically bounded above by the nominal size of the test.

Between the wires are square openings, the numbers of which per unit length give the mesh number and the diagonal the nominal size.

Consequently the internal diameter varies, sometimes significantly, from its nominal size.

The nominal size of a regiment was 590 enlisted men.

The accompanying diagram shows how the actual size differs from the nominal size.
