Hair clipper numbers?

Since summer break is finally here, I really want to keep my hair short (but not bald!) because I have thick hair, so I was thinking about just getting a hair clipper kit and just trim my hair myself every few weeks.

When I usually get my hair cut at the mall, I tell them to use "number 1 1/2" or "number 2" clippers. But I keep forgetting to ask them what those numbers mean exactly; what's the conversion scale? Is a "number two" clipper actually something like half an inch?

i think...

1 = 1/8
1 1/2 = 3/16
2 = 1/4

but i was a beauty school dropout, so i may be wrong

clipper blades and attachments - electric clippers are used to cut hair short. If used directly on the head without an attachment guard, they will shave the hair from the head, leaving a very short stubble. Some clippers use a series of different plastic guards over the cutting blades to adjust the length of hair, while others have different length attachable blades. These clipper attachments (either guards or blades) are used to provide a uniform length of hair to be left. Barbers use both adjustable attachments and standard attachments. Clippers made by Wahl use attachment numbers to indicate the length of hair that will be left. Here are some examples of attachments used by some popular clipper manufacturers.


0000 - 0.1mm (1/250 inch)
000 - 0.2mm (1/125 inch)
1 - 3.0mm (1/8 inch)
1.5 - 4.0mm (5/32 inch) separate regular and texturizing blades available
2 - 5.0mm (1/5 inch)
7 - 4.0mm (5/32 inch)
5 - 5.0mm (1/5 inch)
3.5 - 9.0mm (1/3 inch)

Oster. Oster clippers are often used in military barber shops (they are powered by a motor instead of an electric vibrating device and tend to stay cooler during heavy use). Blades used on Oster clippers include:

00000 - 1/125 inch
0000 - 1/100 inch,
000 - 1/50 inch,
0A - 3/64 inch,
1 - 3/32 inch,
1A - 1/8 inch,
1-1/2 - 5/32 inch,
2 - 1/4 inch,
3-1/2 - 3/8 inch
(Source: Oster information referenced from Authorized Marketing Services.)


#0 (no attachment) - 1/100 inch,
#1 - 1/8 inch,
#2 - 1/4 inch,
#3 - 3/8 inch,
#4 - 1/2 inch,
#5 and #6 - special tapering attachments
#7 - 7/8 inch, and
#8 - 1 inch.

Good info, thanks Numanoid. Yeah, I was thinking about getting the Wahl clippers. Those seem pretty popular.
