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 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.

This guide covers the clipper guards and blades of the 3 most reputable hair clipper brands – Andis, Oster, and Wahl.

 

Navigate to whichever part interests you the most to learn more about these different hair clipper sizes!

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.

I have had people ask me about how securely these guards clip onto the blade. They worry that since there is no clip or clasp that they could pop off mid haircut.

I can assure you that these combs are not going anywhere. In fact, when you need to remove them you have to pull quite hard to get them off! It’s insane how securely they fit on there from just a tiny magnet.

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!

I use these with my Oster 76 without any issues regarding clipper sizes or fit to the blade.

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.

These blades come in all the hair clipper sizes that you would expect and are shaped exactly the same as the carbon steel ones. One word of warning, however, is that they are more fragile than the steel version. If you bagn your clipper, take a close look at the blade to make sure none of the teeth have been broken or chipped.

*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.

There is a version that also stays cooler since it has ridges on the top of the blade that comes in contact with your clients head. Basically, it allows air to flow over the blade and keep it cool. It is also less likely to drag on damp skin since there is less surface area actually touching the skin.

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

Blade numberSize (inches)Size (mm)

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

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.

They’re not cheap, but they are so worth it. For peace of mind alone, you get more than you pay for.

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 are three main types of Wahl clipper guards the brand has in stock for you.

First, there’s the colored plastic combs on Amazon.com. 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.

This takes all the guesswork out of cutting your own hair or cutting other people’s hair at home.  Hair clipper sizes can be really confusing even to the professionals, so it is a great deal to have it made simple for the DIYer.

Wahl guards sizes assorted in the brand's colored plastic combs.
Exactly the same as colored combs, the Wahl black hair clipper guide combs from Amazon.com are your standard kit. Nothing spectacular about them – just your usual accessory to spice up your home haircuts.

They aren’t quite as sturdy as the Oster clippers version but they aren’t too bad, either. They just may not last as many years.

Things are a little different with the Wahl metal clipper guards from Amazon.com. 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 for all hair clipper sizes.
