From the #0 to #10 guard length, every attachment determines how much hair is left after cutting.
Whether you’re aiming for a number 2 haircut, a classic buzz cut, or a tapered fade, this complete guide will help you choose the right hair clipper lengths and create a clean, professional look every time.
What Are Hair Clipper Guards (and Why They Matter)?
Did you know that some of the most on-trend men's haircut styles can be achieved with only a few of the right tools and a bit of know-how?
For beginners unfamiliar with the term, hair clipper guards are attachments that fit onto a hair clipper and help measure the length of the strands you are cutting. These can be used when you visit a barber or when you cut your own hair. Without quality hair clipper or shaver guards, there are some common styles, such as fades, that you won’t be able to achieve—at least not successfully!
Hair clippers are equipped with detachable guards, also called comb attachments, that control haircut length.
Each clipper guard size corresponds to a number, usually between 0 and 12, indicating the millimetre length of hair left after trimming.
For example:
- A #0 guard (1.5 mm) gives a close cut or skin fade, leaving almost no hair.
- A #2 guard (6 mm) creates a short buzz cut or tidy corporate look.
- A #4 guard (13 mm) leaves more volume for a natural finish.
- A #7 clipper length (22 mm) or #10 guard length (32 mm) provides a longer cut, ideal for styling or blending different hair textures.
These numbered attachments make it easy to achieve your preferred male haircut length without guesswork, making it perfect for beginners learning to cut their own hair. Clipper guards are especially important for popular cuts like the men’s fade haircut and burst fade design, allowing you to control the length and create clean, precise lines.
Understanding Haircut Numbers: From 0 to 10
When barbers refer to a “number 2 haircut” or a “number 6 haircut,” they’re talking about the clipper guard number used. Each corresponds to a specific hair length in millimetres.
Make Use of a Clipper Guard Size Chart
Choosing hair clipper guard sizes is significantly easier when referencing a size chart. By having one on hand, you can use this chart to help you find the perfect option for your needs.
Remember: Different hair clipper brands use different clipper guard sizes, each with its own size chart. These guards also differ from blade sizes, which have their own reference size chart, so be sure to consider these when choosing your hair clipper positions or lengths when you cut hair on your own.

These are just some of the main guard sizes, but knowing how they work will help you achieve a great cut at home.
Always start with a longer guard size, then work your way to a shorter one. You can always take more off, but you can’t put your hair back on!
If you’re trimming facial hair, similar rules apply. For example, a 4-guard beard length leaves roughly 13 mm of beard hair, perfect for a short, tidy beard, while a 1-guard taper creates a clean, faded edge near the jawline.
Choosing the Right Guard for Your Hair Type
Different hair types react differently to clipper sizes.
- Thin hair often looks fuller with slightly longer guards (#4–#6).
- Thick or curly hair can handle shorter guards (#1–#3) for sharper fades.
- Coarse hair benefits from mid-range guards that create texture without bulk.
If you’re unsure, always start with a longer guard (such as #7 or #8), you can always trim it later.
The Complete Step-by-Step Guide: How to Cut Men’s Hair with Clippers
1. Preparation
Begin with clean, dry hair. Brush or comb through to detangle knots. If you’re blending beard hair with your haircut, wash and condition your beard, then apply a little beard oil for softness.
2. Choose the Right Clipper and Guard
Attach the guard that matches your desired style. For example:
- Number 2 haircut for a short fade
- Number 4 guard for a standard buzz
- #6 hair clipper length or #7 clipper length for longer textured cuts
A wide range of guards helps you experiment with different styles, from short back-and-sides to longer tops.
3. Start from the Sides
Hold the clipper flat against the scalp and work upwards in smooth strokes. Use consistent pressure and maintain a 90° angle for even trimming.
4. Move to the Back
Work your way from the nape to the crown, following the natural direction of hair growth. Switch between guards gradually to create seamless transitions.
5. Blend the Top
Switch to a longer guard (like #6 or #8) to shape the top. For thicker hair types, use upward flicks to blend layers naturally.
6. Detail and Taper
To refine your look, remove the guard or use a #0 or #1 guard for edges and sideburns. For beards, switch to the appropriate beard guard, typically a #3 guard (10 mm) for short beards or a #4 guard beard length (13 mm) for a more defined shape.
7. Check Your Work
Use a handheld mirror to inspect all angles. Remember that clipper guard sizes vary slightly between brands, so if your cut looks uneven, adjust with a smaller guard or trim your beard to balance the overall look.
Beard Styling and Maintenance Tips
Hair and beard grooming go hand-in-hand. Once you’ve mastered haircut numbers, you can maintain your beard with the same precision:
- Use a 1 guard or 2 guard in mm (6 mm) to clean up neckline fades.
- For a short beard, use a 4 guard or 5 guard in mm (15 mm) for even trimming.
- Apply beard oil daily to soften coarse facial hair and maintain shine.
- Experiment with different clipper lengths to blend your sideburns smoothly into your haircut.
A consistent beard styling routine keeps your facial hair neat and complements your haircut perfectly.
Pro Barber Tips for Flawless Results
- Follow the hair’s natural texture: Wavy or curly hair requires slow, controlled passes.
- Keep guards clean and sharp: Dull guards tug and cause uneven cuts.
- Mind the fade zones: Switch guards gradually (for example, 0 → 1 → 2 → 3 haircut) to achieve a professional fade.
- Don’t rush: Even barbers take time perfecting blends, especially when fading between 0.5 guard (1.5 mm) and 2 clipper guard length (6 mm) transitions.
- Know your lengths in mm: A #5 hair clipper length equals roughly 15 mm, while a number 1 haircut leaves 3 mm of hair. Memorising these helps you visualise results before you cut.
How to Clean and Maintain Your Hair Clippers
Now that you know which shaver or hair guard to choose, it is essential to maintain and clean your hair clippers to ensure quality results when cutting your own hair.
Always remember the two main steps: clean and lubricate.
- Turn Off Your Clippers: Always start by ensuring the clippers are turned off and unplugged.
- Remove Hair Build-up: Remove the head from your clipper and use a clean brush to gently, yet firmly, sweep away any build-up of hair and skin. If your clipper head is not detachable, brush the blade area.
- Rinse and Dry: Rinse the head under the tap to remove debris such as hair or oil. Thoroughly dry the clippers' heads and reattach them to the tool.
- Sanitise and Lubricate: Use sanitiser spray to kill any lingering germs. After all, the last thing you need when learning how to cut hair on your own is to deal with unpleasant infections like folliculitis!
- Invest in Clipper Oil: Investing in clipper oil can help enormously with maintaining your shaver or hair clippers at home.
Ensuring your clippers are clean and well-maintained is crucial for both the longevity of your tools and the quality of your haircut.
Matching Hair Clipper Guard Sizes to Hairstyles
Here’s how different guard numbers correspond to popular men’s hairstyles:
- Buzz Cut: #2 or #3 haircut — short, clean, and low maintenance.
- Crew Cut: #4 guard on top, tapered to #2 on sides.
- Skin Fade: Start with guard 0 near the neck and gradually increase to #2 guard in mm for a smooth transition.
- Textured Crop: #6 or #7 clipper length for a relaxed, tousled look.
- Longer Classic Cut: Use #8–#10 guard lengths for layered styles that keep volume and movement.
