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!
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.
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.
Short Andis magnetic guards set
| Guard number | Size (inches) | Size (mm) |
|---|---|---|
| #0 | 1/16" | 1.5 |
| #1 | 1/8" | 3 |
| #2 | 1/4" | 6 |
| #3 | 3/8" | 10 |
| #4 | 1/2" | 13 |
Long Andis magnetic guards set
| Guard number | Size (inches) | Size (mm) |
|---|---|---|
| #5 | 5/8" | 16 |
| #6 | 3/4" | 19 |
| #7 | 7/8" | 22 |
| #8 | #1 | 25 |
Tight and secure fit, durability and facilitation of more precise, easier haircut
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.
Andis CeramicEdge blades chart
| Blade number | Size (inches) | Size (mm) |
|---|---|---|
| #00000 | 1/125" | 0.2 |
| #000 | 1/50" | 0.5 |
| #0A | 3/64" | 1.2 |
| #1 | 3/32" | 2.4 |
| #1A | 1/8" | 3.2 |
| #1 1/2 | 5/32" | 4 |
| #2 | 1/4" | 6.3 |
| #3 1/2 | 3/8" | 9.5 |
| #3 3/4 | 1/2" | 13 |
| #5/8 | 5/8" | 16 |
*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.
Provides you cool operation mode, longevity and, overall style.
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 number | Size (inches) | Size (mm) |
|---|---|---|
| #00000 | 1/125" | 0.2 |
| #0000 | 1/100" | 0.25 |
| #000 | 1/50" | 0.5 |
| Modified 0A | 1/50" | 0.5 |
| #0A | 3/64" | 1.2 |
| #1 | 3/32" | 2.4 |
| #1A | 1/8" | 3.2 |
| #1 1/2 | 5/32" | 4 |
| #2 | 1/4" | 6.3 |
| #3 1/2 | 3/8" | 9.5 |
| #3 3/4 | 1/2" | 12.7 |
| Flattop T | 1/50" | 0.5 |
| 18 Skiptooth | 1/8" | 3.2 |
| Texturing Blade | 1/8" | 3.2 |
They’re ultra tough, ultra sharp and will last you a long, long time
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 number | Size (inches) | Size (mm) |
|---|---|---|
| #0 | 1/16" | 1.5 |
| #1 | 1/8" | 3 |
| #2 | 1/4" | 6 |
| #3 | 3/8" | 10 |
| #4 | 1/2" | 13 |
| #5 | 5/8" | 16 |
| #6 | 3/4" | 19 |
| #7 | 7/8" | 22 |
| #8 | 1" | 25 |
| #10 | 1 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.
They’re not cheap, but they are so worth it. For peace of mind alone, you get more than you pay for.
Amazing for shaping buzz cut lengths
Wahl clipper sizes
Wahl guard sizes chart
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 number | Size (inches) | Size (mm) |
|---|---|---|
| #1/2 | 1/16" | 1.5 |
| #1 | 1/8" | 3 |
| #2 | 1/4" | 6 |
| #3 | 3/8" | 10 |
| #4 | 1/2" | 13 |
| #5 | 5/8" | 16 |
| #6 | 3/4" | 19 |
| #7 | 7/8" | 22 |
| #8 | 1" | 25 |
| #10 | 1 1/4" | 32 |
| #12 | 1 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.
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.

I’m an outdoor enthusiast and have sported a full beard since I was in my early 20’s. Originally, growing a beard was a way to save time when getting ready each day, but I quickly realized that keeping a neatly trimmed beard takes work and some forethought. That’s where this site comes in.
You get to benefit from my years of experience. I’ve reviewed many of the top hair clippers on the market today and also included some information on what works best for me. A great beard will turn lots of heads in your direction.
Since I never know when I’m going to find myself being photographed, whether it’s climbing in Yosemite, or playing volleyball on the beach, it’s important to me to always look my very best. Maintaining my beard is part of my daily routine and I hope you’ll find some useful tips and information on this site to help you on your journey.
Didn’t even know that those metal wahl combs existed…thanks for the heads up. Went ahead and grabbed the 1/2 + 1 1/2 set for my seniors clippers 🙂
Any idea why Wahl do not produce a #9 guard?
I find #8 too short and #10 too long.
Ideally I would like a 28mm cut.
Does anyone do a guard of that length?
Thanks
Looking for comb guide #10,#12 & #14 with metal clips. Where to find them? Thanks.
Hi Roger!
Unfortunately, we haven’t seen any metal guards longer than the #8 included in Wahl’s set. Seems like they have limited the premium feature to shorter, more ‘standard’ sizes.
I did not see that he listed a #0 guard for the walhs brand. Dude Yhu should reread it before you comment
I use a 0,1/2, 1, 1 1/2, 2 to fade my own hair. Do they make a 2 1/2? I try to blend into a 3 & 4 but leaves a line. I’m not good enough to get rid of lines with no guard and a comb Or scissors like you professionals! Thanks!
Use the Oster they come with the metal blades go From 000-3. So you can put plastic guard #8 with the 3 metal blade. Equals #11. I found 8-12 guards for the Oster
U have the wahl clip/comb sizes listed incorrectly, there is no zero comb for wahl there is the half clip and where is the 1 and 1/2 clip? Also a number 2 detschable blade is well known througHouten the industry to be longer then the detachable 2 blade, you have it listed that the detachable 2 leaves the hair longer. Why?
Hey Louon 🙂
Oops, you’re right about the #1/2 — I noticed just now that we’ve listed it as a #0 like Andis and Oster. Our bad.
Regarding the detachables, I didn’t quite understand you. The detachable blade sizes are taken in accordance with what the manufacturers (Oster, Andis) have pointed out in their official pamphlets and websites.
Cheers,
Alex
I have the wahl clippers and blades #40,10,7,5,4 and 3 1/4. I just purchased the wahl guides but I don’t have a clue to which blades I am supposed to use with them. Do I just use the #40 or #10 or do I use all the other blades depending on the extra length I want?
Hi Sam!
This is a set of dog clippers you’re talking about, right? Human clippers don’t have sizes like #40, #10 etc. It’s a matter of personal preference – some people groom only by switching blades, others by further attaching guides.
Which guides did you buy, btw? Human clippers and dog clippers differ a bit.
#10 is the most standard dog clipper blade you’ll see on most clippers. Beginners tend to use it, as it leaves hair long enough to be comfortable for most breeds.
Scroll to the very bottom of our article here to learn about all the dog blade sizes: https://www.hairclippersclub.com/best-dog-clippers-dog-grooming-scissors-guide/
As I said, most beginners go with the #10, but additionally check this guide on breeds (not sure what yours is): https://clipperworld.com.au/which-clipper-blade-breed-guide-i6.html
Just keep in mind that some clippers can get hot. Make sure you have a cooling spray/make pauses from time to time!
Let me know if you have any further questions,
Alex
Hey man, nice post. One question remains though. What size is it when I have my Oster Fast Feed closed with Andi’s magnetic combs?
Is it Andi’s magnetic combs + 0.5 mm?
On a wahl senior, when the blade is closed with no guard it is 0.5mm. How many milliliters is it when the wahl seniors are all the way open with no guard? Is it 1.4mm?
Hey Fiddle,
You mean the regular Seniors, not the 5 stars, right?
It should be the length of ~#1/2 Wahl guard, or roughly 1.5mm when it’s open without a guard.
Cheers!
Alex
I have oyster classic 76. Can you use Andis blades with them? If so have you noticed a difference in those blades vs oster.
Hello, Chelsea.
You CAN use Andis blades with Oster clippers (and vice versa.) And they would work somewhat well, but there’s a small issue: the hinges.
Oster clippers are manufactured so they have narrower hinges; Andis are wider. This could make blades noisier and affect their cutting precision.
Here’s a good concise resource on that: http://www.lovessharpening.com/images/switchingclippers_pdf.pdf
Hope that helped,
Ryan
So my question is , like what # guard 0a 5/16 speed-o-guide, is equivalent to what Wahl or Andis purple guard?
I purchased a Wahl 5 in 1 blade cannot figure out how compares to the comb sizes like a size 10 would be which 5 in 1 setting
Hey Donna!
If you’re talking about the 5-in-1 fine blade, it’s usually used for pets and not humans. Can you confirm which one is it?
Animal clipper sizes and human clipper sizes differ a lot.
Best,
Alex
I have a Moser 1881 which has a 1 9/16 inch head. (Or 39.5mm).
Can I use standard Wahl (or similar) guides on it?
You description above does not mention the standard width of the head to fit the standard guides…
Hi, is there a 2 inch clipper size for human use, and if so what is the clipper number and where can i purchase it?
Thank you
Hello, I’ve just purchased the wahl chromado lithium, Will these guards fit. Also I’m used to using guards #1 to #6, how do I convert the sizes.
Many thanks.
Hi Celia. Thanks for your question.
Unfortunately, you cannot interchange the guards for the Wahl Chromando Lithium. You have to use the 5-in-1 blade.
Secondly, the Wahl Chromando Lithium comes with the following attachment guide combs: 6 Attachment Guide Combs: (#1 -1/8” (3mm) cut; #2 -1/4” (6mm) cut; #3 -1/3” (9mm) cut; #4 -1/2” (12mm) cut; #6 -3/4” (18mm) cut; #8 -1” (25mm)
Thank you for taking the time to answer.
My pleasure.
Hi! Does all the wahl guards fit to all wahl clippers?
/ morgan
Hi Morgan. Thanks so much for your message. From what I can see, the color-coated plastic Wahl guards should fit Wahl full-size clippers, which excludes trimmers.
The Wahl metal clipper guards are compatible with most full-size clippers with the exception of Wahl’s competition series and detachable blades.
On the Wahl right and left ear taper guards, can anyone tell me what the equivalent guard size is for the two sides? It looks like it may taper from a 2 guard on the high side to the 1 guard on the short side but I am not sure. I wish they made different lengths on the tapered guards, I think they could really help with fading.
Hi Jason. Good question. The Wahl left and right ear taper guards range from 1/8” to 1/2”, so the equivalent guard size would be a 4 on the high side and a 1 on the low side. That’s a good idea. I definitely agree with you there.
The Wahl #12 or 1 + 1/2 inch guard is not the largest guard size designed for human hair. There are actually generic #16 guards made for Wahl Clippers made by a 3rd party company which allow the hair to be cut at roughly 2 inches long. I believe the company that makes them is called Clipquik and they are compatible with Wahl clippers and maybe Conair clippers also. If your clipper has a side-lever for adjustable length then you can even get it to cut the hair at almost 2 + 1/4 inches long. I wear a shorter classic style mullet hairstyle and either use the #12 or #16 guard with the long lever setting for one length on the front, top, and sides. There is no tapering. I use a vacuum electronic haircutter (not mentioned on this site) or have another person cut / trim the longer portion of hair in the back. I’ve been self-cutting my hair in this style since 2005 with little changes made since then.
hello, can i cut my own hair only using a 3mm,6mm and 9mm only because my clippers doesnt have lever to make a fade. help me please
I have my father’s old “Renown Ace Clippers” from the 1950s purchased from Eaton’s Of Canada. The instructions recommend Wahl oil for lubrication and the bottom of the blades says “WAHL 000 SOLID”. It is in great condition and I would like to use it again. I am interested in buying new guards but I am not sure if the current Wahl guards will fit. Can you help me?
I’m going to assume this was an item made by Wahl, under license/contract for a major retailer at the time (how sears did in the US). Wahl clippers really haven’t changed much in their basic design in years – nor have Andis and Oster, so I’d put money on modern guards working just fine. If not, look into speed-o-guide combs.
What would be the sizes of cut if say wahl guards are used in direction of hair growth, like on top of head?
Is there any way to setup a clipper to cut at 1-3/8″…I looked everywhere and there doesn’t seem to be a #11 guard. I have been cutting my own hair for a while and it just seems the #10 is too short even when I use the lever on the clippper and the #12 is too long.
