How to Measure Scissor Blade?

Are you wondering about how to measure a scissor blade? To measure the blade length of your professional hairstyling shears, use a tape measure. Place the tape measure at the base of one of the blades and stretch all the way to the screw holding the two pieces together. Remember that the blade length is from the tip of the blade to the screw and not to the total length of scissors.

How to Measure Scissor Handle Length?

From this point, measure straight to the end of the handle. If the shears have detachable tangs, they are not considered in the handle length but if the tangs or finger rests are fixed, they will be added in the measurement.

For measuring the size of finger holes, you will be needing a special device called the vernier caliper. This device can be used to measure the diameter of the circle formed by the finger hole. Fix the shear’s finger hole between the vernier caliper’s teeth and measure the diameter of the circle formed using the digital meter. Vernier calipers are only suitable for shears with rounded finger holes. As a general rule of thumb, longer shears are used for cutting through thicker hair, have texturizing properties while the shorter shears are more suitable for point cutting.

Some Common Misconceptions About Measuring Scissors

An important misconception to address is the measurement of scissor blades. Contrary to common belief, the length of the blade is not measured from the tip to the end of the handle. In practice, the measurement is taken from the blade’s tip to the start of the handle. This measurement, known as the cutting length, holds significant importance in selecting the appropriate shear for professional hairstyling purposes.

It is crucial to dispel the misconception that the length of the scissor blade is the sole determinant in choosing an ideal shear for hairstyling. In reality, several parameters come into play, such as shear length, blade length, the ratio between blade length and handle length, material, and handle type. Considering all these factors is important when selecting a professional hairstyling shear.
