Mesh
designates the number of openings and fractional parts of
an opening, per lineal inch. To determine the mesh, count
the number of openings from the center of any one wire to
the center of a parallel wire, one inch in distance: Figure
#1 illustrates a four mesh count. When the point an inch distant
from the center of a wire falls between wires, the mesh count
is expressed in fractions. Figure #2 illustrates a 3-112-mesh
count. (3-112 openings from center of any wire to a point
one-inch in distance.) When two parallel wires are on centers
of 518", 314", etc., they can be expressed as 518"
mesh, 3/4" mesh, etc.

Space
"Space" is the actual "clear opening"
or space between inside edges of two parallel wires.
It should be carefully differentiated from the terms
"Mesh." see above
