by | 12 comments

Once the bug of doing your own haircut with clippers bites you, it won’t let go. Forget about it making sense in terms of saving $$$. It’s seriously addicting!

However, cutting your own hair can also get confusing. There’s a scary amount of hair clipper guard sizes!

Thought that blades are easier? Oh man, think again when you see all these clipper blades too.

Me and Alex compiled a full guide for you, including a concise infographic with guard lengths.

You’ll find anything from Andis detachable blades chart or Andis purple magnetic guard sizes, to Oster guards/blades or Wahl guides charts.

Navigate to whichever part interests you the most to learn more!

A comprehensive guide to hair clipper sizes, clipper guard numbers and buzzcuts.

Andis hair clipper sizes

Andis Magnetic guard size chart

Let’s start with Andis’ most popular accessory: the brand’s Nano magnetic combs. The company divides them into two sets – five shorter magnetic guards and four longer. The reason these are so revered is their tight and secure fit, durability and facilitation of more precise, easier haircuts.

In addition, they are compatible with some other hair clipper models. For example, Andis magnetic guards will fit Oster Fast Feed without any problem. Just make sure you get the double magnetic guards. Here’s the Andis magnetic guards size chart itself!

Andis detachable blades chart

A few of Andis professional clippers come with ceramic blades. What’s great about them is their cool operation mode, their longevity and, you know, their overall style. Ceramic blades for Andis clippers will net you up to 70% cooler blade operation, which is great for heavy-duty haircuts. An alternative would be the UltraEdge blades which, however, are not made of this material.

The most popular model rocking the CeramicEdge blades is Andis BGRc, an amazing barber clipper we’ve reviewed thoroughly. Andis detachable blades also fit other top hair clippers like the Oster 76 Classic. Here’s the ceramic Andis clipper blades size chart to help you out.

*All Andis detachable blade clippers can use the Andis comb set for detachable blades. It consists of Andis guards sizes 0 to 8 (1/16″ to 1″) and fit a #000 blade perfectly.

Oster clipper sizes

Oster clipper blades chart

Oster detachable blades are an art of their own. Made of high-carbon steel, they go through freezing cold conditions and rigorous in-house testing. As a result, they are hardened to the spectacular RC62-66 Rockwell Scale.

If that doesn’t speak anything to you, let’s put it this way: they’re ultra tough, ultra sharp and will last you a long, long time. That’s how the Oster Cryogen X blades work. As Oster detachable blade clippers have hordes of fans, we’ve compiled all Oster clipper blade sizes for your convenience.

And if you’re wondering: yes, this is a compatible Oster Classic 76 blades size chart too.

Oster clipper guards sizes

Oster’s adjustable hair clippers are amazing for shaping buzz cut lengths too. It would be unfair to skip a clipper guard size chart with Oster’s own combs. Of course, these accessories can also serve as Oster Classic 76 clipper guards (or any other Oster detachable cutter.) Here are the clipper guard sizes this brand offers you:

Guard numberSize (inches)Size (mm)
#01/16"1.5
#11/8"3
#21/4"6
#33/8"10
#41/2"13
#55/8"16
#63/4"19
#77/8"22
#81"25
#101 1/4"32

I’ve had a few people asking me about “Oster Fast Feed magnetic guards”, as they call it. I’ve discussed this before: there’s no such thing from Oster. You simply get Andis Nano double magnetic combs and use them with your Fast Feed clipper. Easy as pie and way better than any plastic comb, in my opinion.

Wahl clipper sizes

The last member of the holy trinity of the most popular hair clipper brands is Wahl. You’ll see quite a few Wahl clipper reviews around the website with a reason. Alex is especially fond of them, while I lean more towards Oster and Andis.

There’s quite a few types of Wahl guards around. Let’s first get to the clipper guard sizes and the chart. We’ll discuss the types afterwards. Note: Wahl clipper hair clipper sizes include the #10 and #12 comb.

Guard numberSize (inches)Size (mm)
#1/21/16"1.5
#11/8"3
#21/4"6
#33/8"10
#41/2"13
#55/8"16
#63/4"19
#77/8"22
#81"25
#101 1/4"32
#121 1/2"38

If you’re looking for Wahl replacement guards, or just something to style your haircut sizes with, you’re in luck. There’s three main types of Wahl clipper guards the brand has in stock for you.

First, there’s the colored plastic combs. Each color corresponds to a specific size. This is perfect if you’re using a home hair clipper for all the family. If everybody’s haircut sizes differ, it would be quite the hassle, no? These combs make it easy to distinguish which guard you should use for a 2 guard haircut and which for a number 2 haircut, for example.

Exactly the same as colored combs, the Wahl black hair clipper guide combs are your standard kit. Nothing spectacular about them – just your usual accessory to spice up your home haircuts.

Things are a little bit different with the Wahl metal clipper guards. They run more expensive than standard combs, but also bring you a premium approach to hair clipper sizes. With the 1/2″ and 1 1/2″ Wahl guide with metal clip you’ll be achieving fades you wouldn’t get that easy with the simply plastic combs. This is just pure luxury and will complement any Wahl 5 star clipper you have.

We sure hope these collection of clipper guard sizes in charts would help you perfect your haircut. Not only this – but also improve your knowledge on cutting your hair with clippers and general understanding of these awesome machines. We did go deep into clipper lengths, but we might have missed something out.
