Precision Cutting Techniques
Precision cutting relies on understanding the mathematical relationships between elevation angle, finger position, over-direction and the resulting hair shape. Whether you are creating a classic one-length bob, a heavily layered style or a seamless skin fade, knowing the numbers behind the technique helps you achieve consistent, predictable results.
Clipper guards (also called combs or grades) come in standardised sizes. A grade 1 cuts to 3mm, grade 2 to 6mm, grade 3 to 10mm and grade 4 to 13mm. Half-grades (0.5, 1.5, etc.) provide intermediate lengths for smoother fade transitions. Understanding these measurements is essential for communicating with clients and achieving precise results.
Elevation (the angle at which hair is held from the head during cutting) directly controls where weight and volume sit in the finished style. Zero elevation builds maximum weight at the perimeter. 45-degree elevation creates graduation. 90-degree elevation produces uniform layers. 180-degree elevation (over-direction) creates shorter interior lengths and maximum movement.
