Haircut Blade Sizing Guide

Barbers and stylists rely on using the appropriate clipper blade to achieve their desired style, but its size/numbering may vary between clipper guard sizes. Disorientation when trying to communicate what you want with a barber or stylist can make communication challenging, which is why we’ve put together our guide of haircut numbers to assist in helping clear communication.

Blade Length

This blade size is perfect for creating the classic crew cut look. Before selecting any blade length, make sure that you discuss with your stylist what desired result you are going for.

Adjustable Blade Gap

This blade allows you to customize the gap between its cutting and guide blades according to your taste. Open up your trimmer and turn its bevel dial until you find your ideal hole – this also helps avoid unwanted nicks or cuts on the skin!

Blade Material

Stainless steel blades are standard on most hair-clipper edges and offer optimal performance and value. However, their sharpening must be performed every six months for optimal cutting results.

Ceramic blades have recently made waves in the haircutting world. Not only can they keep heads 75% cooler over long periods than steel blades, but they’re also a joy for barbers looking to avoid adding heat onto clients’ scalps. Unfortunately, ceramics break more easily than stainless steel ones and are more costly to replace than their metal counterparts.

Some stainless steel blades have been treated to make them more complicated and durable, lengthening their lifespan while rusting is still an issue. Furthermore, stainless steel is easier to sharpen and sanitize than ceramic alternatives.

Titanium blades have become an increasingly popular option due to their lightweight nature, lessening skin irritation. Titanium also boasts excellent corrosion resistance compared to steel and may last longer than traditional stainless blades.

Zero-gap blades

Zero-gap blades should be set up so that their top movable blade doesn’t extend past their fixed bottom edge – known as zero-gap. Proper alignment will prevent your knives from snagging or pulling on hair and skin, which may cause irritation and cross-contamination between clients. Regular cleaning with a dry cloth and using blade or fade brushes will keep them clean and healthy.

Blade Type

Steel is usually the go-to material for haircut blades. In contrast, ceramic or titanium blades may offer superior sharpening qualities and resist corrosion better – these tend to last longer and provide higher-quality cuts despite potentially costlier pricing models.

Taper blades are ideal for precise fades and produce a softer finish. They are also helpful when trimming around ears and face areas. Ensure that the gap remains small to avoid lines in the hair.

Wedge blades fall between taper and fade blades and are great for intermediate to advanced barbers. They provide a clean finish and blend fade lines effectively while seamlessly transitioning from short hair to longer locks.

Graphite blades are perfect for creating fine lines and detail work. They are also safer for children and babies as they don’t dig deeply into the skin. Regularly remove any hair that enters the blade to protect its longevity and prevent blade dullness over time.

Following this guide, you can effectively communicate with your barber or stylist, choose the right blade size, and achieve your desired haircut style.
