Fractional aiming

Also called: Ball fractions, Overlap aiming

What is fractional aiming in pool?

Fractional aiming judges cuts by how much the cue ball overlaps the object ball at contact: full ball (0°), ¾ ball (about 14.5°), ½ ball (30°), ¼ ball (about 49°) and thin. You learn the angle each fraction makes, then match the shot to the nearest one.

In more detail

Fractions give a concrete visual target instead of an imaginary ball, and you can interpolate between them. Many players use them to calibrate ghost-ball aim.
