How to Read a Clipper Number
- →Lower number = shorter cut. A #1 cuts shorter than a #3.
- →The number roughly equals the fraction of an inch it leaves behind.
- →Guard 0 leaves almost nothing — about 1.6mm of stubble.
- →Guards above #4 are mostly used on the top, not sides.
- →Half guards (0.5, 1.5) are Wahl-specific — other brands may not include them.
Do Wahl, Andis, and BaByliss Guards Match?
Not always. Wahl guards are the most standardized. Andis and BaByliss use slightly different attachment systems — always check compatibility before mixing brands. Wahl half-guards (0.5, 1.5, 2.5) are not available for Andis without adapters. BaByliss FX guards tend to run slightly longer than Wahl equivalents at the same number.
PRO TIP
Pro tip: When a client says "short on the sides," ask which number they had last time. Most clients mean a #2 or #3 — never assume.
FREQUENTLY ASKED QUESTIONS
What guard should I use for a fade?
Start with a #2 or #3 at the bottom of the fade depending on how tight the client wants it. Blend up through #1.5 and #1 before going to skin with a zero-gap or balding clipper.
What is a number 2 haircut?
A number 2 clipper guard cuts hair to 1/4 inch (6.4mm). It produces short sides with a clean, tight look — one of the most requested lengths in barbershops.
What number clipper do barbers use for skin fades?
For skin fades, barbers typically use a #1 or #0.5 in the transition zone, then go to bare skin using a zero-gapped clipper or a dedicated balding clipper like the Wahl 5-Star Balding.
Are clipper guard numbers universal?
No. While the numbering system is similar across brands, the actual cut lengths can vary slightly. Wahl guards are the most widely standardized. Always verify lengths if switching brands mid-fade.
