Now that we understand how the clipper guards are measured and sized, here is a generic size chart to give you a general idea of the relations between the ‘numbers’ being used by the brands and the sizes of the guards in real units (inches or mm). The inches or the mm sizes are exactly the same though! So when in confusion, refer to the actual measurements given on the packaging/product listing when buying them.This means that a 3mm guard might be called a number 2 by brand X while the same size is referred to as number 1 by a different brand Y.Different brands give different ‘numbers’ to different sizes in inches or mm.note: this is just the manufacturing measurement and is mostly not used in the industry to refer to different size guards.Guards’ sizes are measured in inches or mm during the manufacturing process.Let’s try to get this straight in a few points. The present market can be extremely confusing for both newcomers and even experienced people in the field sometimes because of the different metrics and gradings used by the different brands to measure the sizes of the guards. Now that we have an idea of clipper guards, you understand their value and would like to give them a try, the next question that comes up (and is titular), is the size. Clipper guards are therefore used less to guard the hair and more to cut hair accurately. They can help us set exactly the amount of hair we want to be removed and work with laser precision when an appropriate guard is used by trained hands. In other words, they help us regulate the amount of hair that the blade takes off in one cut. They stop the blade from making a cut too far down the hairline. So like the name sounds, they are ‘guards’.

If you’re new to the field or don’t have the best idea about clipper guards, we got you covered: What hair clipper guards are (A short explanation): We’ll start with a bit of background though. We will try to understand how the different sizes work, what some of the popular brands in the market today are offering, and how they relate to each other. Here we will take a look at the different hair clipper guard sizes that are available in the market.
