group size is measured between the two shots that are the furthest apart, center to center (thus, group size doesn't depend upon caliber).

For most accurate measurement, one uses a slide caliper which is attached to transparent plastic with various caliber circles scribed on it. You slide the caliper until the holes line up and read the setting (it's not as complicated as I make it sound). You can get these instruments from shooters supply places.
 
Hi, Glock-man,

Ok, let's take the upper left target.

First off, in rifle or pistol shooting, this is called a group. Patterns are for shotguns. These targets are not numbered and are used to provide an aiming point rather than a match score.

This is (I assume) a five shot group, though I can only actually see four holes; the other one went through the center of the group.

First, eyeball the group and pick the two holes furthest apart. You can do this with a caliper, but here it is obvious that the holes on the left and the right are farthest apart.

Now, measure the distance between the centers of those holes. This is the group size. In this country it is almost always given in inches.

If you can't easily find the centers, you can measure the distance between the outside edges, but you then have to subtract the bullet diameter to get the group size. (Subtract 1/2 the bullet diameter on each side, which is the same as subtracting the full bullet diameter.)

Since I am not sure of the scale and all, I will assume the group size is as the note says.

This shooter was shooting for group size, not score. If you are shooting for score, the target rings are numbered, with a small "x" ring in the very center, then the 10 ring, 9 ring, and so forth. Most targets go down to only 4 or 5 and anything outside that scores as a miss.

The "x" ring is a tiebreaker, since many good shots will score all 10s. Of course, it is a tiebreaker even if the tied scores are 65; if one shooter has an x and the other only a 10, the x shooter scores higher.

When scoring, a bullet hole that "cuts" the white ring of a higher score counts as that score. There are gadgets with magnifiers to resolve questions, and official scorers at formal matches whose word is law.

These groups were shot at seven (7) yards. If the author of that article had increased that distance, I think the picture would have made more sense to you, as the groups would have been larger leaving several well defined bullet holes.
