Number 4 Length

The Number 4 haircut length is 1/2 inch, or 13mm long, striking the perfect balance between style and maintenance. This versatile choice provides ample room styling options while ensuring a well-groomed appearance.

When we talk about the “Number 4 cut all over,” we refer to a haircut where this 1/2 inch length is maintained uniformly across the entire head. This creates a symmetrical, even appearance, giving a clean, consistent look. The balanced proportion of the Number 4 haircut all over is the secret behind its adaptability. This length can be dressed up or down, depending on the occasion or the image you want to project.

A variation to the all-over style is the “number 4 on top haircut,” where the top of the hair is left at the Number 4 length, while the sides and back can be cut shorter. This offers another level of dimension and flexibility to the haircut, making it even more versatile. With the number 4 on top, you have more room for texture and styling options while maintaining a clean, well-groomed look.

Regardless of how you rock it, this length offers an ideal balance of style, versatility, and ease of maintenance, making it a popular choice for men of all ages and lifestyles.

Styling the Number 4 Cut

The Number 4 presents a wealth of styling possibilities to elevate your aesthetic:

Number 4 Fade Haircut: The fade cut is known for its gradual transition from a longer length on top to a shorter length on the sides and back.

With a Number 4 fade haircut, you maintain the traditional 1/2 inch length on top and have your barber gradually fade the sides down to a shorter length. This gives a clean, modern aesthetic that adds a touch of sophistication. Use a moderate amount of hair product to enhance the texture and define the fade.

Number 4 on Sides Haircut: The Number 4 on sides haircut involves keeping the sides and back of the head at the Number 4 length, while the top is left longer for more styling versatility.

This hairstyle is perfect for those who want a balanced look that combines both short and longer lengths. Style the longer hair on top as per your preference—slicked back, swept to the side, or even tousled for a more casual look. Use a suitable hair product to maintain the style throughout the day.

Textured Quiff: Employ a texturizing product with a matte finish to achieve volume and definition. Apply it to damp hair, then utilize your fingers or a comb to style the hair upwards and slightly forward, crafting a textured quiff that exudes dimension and height.

Classic Side Sweep: For a timeless and sophisticated appearance, sweep your hair to the side. Utilize a small amount of styling product to hold your hair in place, then employ a comb or your fingers to establish a sleek and polished side part.

Messy Crop: Embrace a more relaxed and effortless style by tousling your hair with a texturizing product. Apply the product to dry or slightly damp hair, using your fingers to create a tousled and naturally disheveled look.

Maintaining the Number 4 Haircut

To keep your Number 4 cut sharp and stylish, adhere to these maintenance tips:

Regular Trims: Schedule visits to your trusted barber every 4-6 weeks to maintain the desired length and shape of your haircut. Regular trims prevent hair from becoming unruly and ensure clean lines, preserving a neat and refined appearance.

Proper Washing and Conditioning: Utilize a gentle shampoo and conditioner to cleanse and nourish your hair and scalp. Regular cleansing rids your hair of dirt and product buildup, while conditioning moisturizes and revitalizes your strands, leaving them soft and manageable.

Shielding from Heat and Sun: If you frequently employ heat styling tools or expose your hair to the sun, protect it from potential damage. Use heat protectant sprays and consider adorning hats or applying sunscreen to safeguard your hair and scalp from the harmful effects of UV rays.

Final Thoughts

The Number 4 haircut strikes the perfect balance between confidence and versatility, providing a confident clip that opens the door to many styling possibilities. With its adaptable length, it complements various face types and hair textures, empowering you to embrace a polished or casual look with ease.

By adhering to proper maintenance techniques, utilizing recommended products, and drawing inspiration from influential individuals who have confidently sported the Number 4 cut, you can effortlessly redefine your personal style and emanate a remarkable sense of self-assurance.


    • A Number 4 haircut is rather short, but not as short as a buzz cut or a bald fade. The hair is still long enough to comb and style in different ways, providing some flexibility while maintaining a clean, well-groomed look.


      A Number 4 haircut all over looks even and balanced, with the same 1/2 inch length maintained uniformly across the entire head. This gives a neat and tidy appearance. A Number 4 haircut can also be styled with a fade or a taper on the sides, where the hair gradually shortens from the top to the sides and back. This results in a more textured and dynamic look, with more hair on top for styling.


      It’s worth noting that while the Number 4 haircut refers to a specific length, the final look can vary greatly depending on factors like hair type, hair color, face shape, and how you choose to style it.

      • It should take two to three weeks for a number 3 to become a number 4 haircut.


        A Number 3 haircut leaves your hair at a length of approximately 3/8 inch or about 10mm, while a Number 4 haircut leaves your hair at 1/2 inch or roughly 13mm long. Therefore, you are looking at a difference of about 3mm in length. On average, human hair grows about half an inch per month or roughly 1.25mm per week. Given this, it would take approximately two to three weeks for a Number 3 haircut to grow to a Number 4.


        Of course, this is a rough estimate. Individual hair growth rates can vary due to factors such as genetics, diet, health, and age.

        • You should visit your barber every 4-6 weeks for a trim to maintain the desired length and shape of your number 4 haircut.

          • You can create texture with a number 4 haircut by using a texturizing product and styling your hair with your fingers or a comb to achieve a desired tousled appearance.

            • The Number 4 haircut can add definition and structure to round faces, helping create a more angular and sculpted appearance.

              • The Number 4 haircut offers versatile styling options. Consider a sleek side sweep or a well-groomed quiff for a refined and sophisticated look.
