Either estimate the distance, or measure it. A compass is used by navigators to measure the distances between successive points, and to compare distances against the scale printed on the chart.

Compare the distance to a known length. Measure. If you know the coordinates of the two dots in an orthogonal coordinate system, use Pythagoras' theorem to find the distance. Say point 1 has coordinate (Ax,By) and point 2 has coordinate (Cx,Dy) then the distance between 1 and 2 is the square root of ((C-A)2 + (D-B)2))

Dot pitch
For the NC test I used google earth and my closest DVM that has the motorcycle course dots painted on the ground. You can easily see these dots in google earth and you can use the ruler tool in google earth to measure the distance between the dots. The distance between the center dots is 14 feet and the dots that are to the left and right are 4 feet from the center line of dots. Diagrams of the actual skills tested are at the end of the of the NC Motorcyclist Handbook.
What happen to the number of dots per unit area as the distance of dots go farther from the center
Isometric drawing paper either has dots on it with very minimal distance in between them, or has very small triangles or diamond shape with no distance in between them. It is available in different sizes and varieties.
The dot pitch for a display unit is the distance between individual dots - which may be circular or in the form of an elongated circle (like a running track). Most display units, nowadays, are based on dots of three colours: red, green and blue. A pixel is unit formed by each set of three colours, and a pixel pitch is a measure based on the size of the pixel and the distance between dots of the same colour in adjacent pixels.
You spread the dots apart?? Derrrp :D
The black dots and dashes between states on a map represents the state boundaries. The dots and dashes are used to outline the state.
