Factors to Consider

When deciding on the number of bundles needed for a sew-in, take into account several crucial elements. These elements not only influence the final look but also determine the overall comfort and longevity of your sew-in hairstyle.

Desired Length

The length of your hair can significantly impact the number of bundles you’ll need. It’s a straightforward rule: the longer you want your hair, the more bundles you’ll require. This ensures that from top to end, your hair maintains a natural and full look.


If you’re aiming for voluminous, luxurious locks, you’re going to need more bundles. But if you prefer a flatter, more natural look, fewer bundles may be necessary. So, let your style goals guide your decision.

Your Head Size

It’s important to consider your unique head size. Smaller heads typically require fewer bundles, while larger heads could need more. Remember – it’s all about achieving a balanced and proportionate look, so don’t overlook this factor!

Type of Hair

The type of hair you’re using plays a big role too. Different types of hair have different densities and wefts. For example, with thicker hair types like Brazilian or Peruvian, you might need fewer bundles than what you’d need with a thinner hair type like Malaysian or Indian.


The style of sew-in weave you’re aiming for also changes the bundle count. Some methods, like the vixen sew-in, require more hair than simpler, straight sew-ins.

Take all these factors into account when deciding on the number of bundles for your sew-in. Not only will it ensure an amazing end-result, but it’ll save you from the hassle of untangling the unnecessarily complicated math behind the perfect sew-in! The key to an amazing sew-in hairstyle lies in careful planning and coordination according to these factors.

Calculating the Right Amount

Determining how many bundles you need for a sew-in couldn’t be more critical to achieving that perfect look. Buyers often ask, “How many hair bundles do I need?” The answer isn’t a one-size-fits-all but a calculated measurement tailored to your specific needs.

The desired length of your sew-in is a major factor to consider. Typically, the longer the length, the more bundles needed. Why? Because hair bundles are measured by weight. Therefore, as the length increases, the weft (or top) of the bundle becomes thinner. So, you’ll need more bundles for fuller coverage.

Here’s a general guide to help you plan:

Hair Length(inches)Number of Bundles
10 – 122 – 3
14 – 163 – 4
18 – 224 – 5
24 – 305 – 7

Another influencing factor is the desired volume or thickness. Are you looking for a full, bodacious look or a more natural, everyday style? A higher number of bundles will give you a fuller appearance. So, consider the volume style ahead of time.

Your head size can also impact the bundle count. This is because larger head size may need more bundles for full coverage. It’s a nugget of knowledge often overlooked but undeniably impactful when calculating the right number of bundles.

The type of hair used can also influence the bundle count. For example, if you’re using denser or fluffier hair types like kinky or curly hair, you may not need as many bundles compared to when using straight hair.

Lastly, the hairstyle you’re seeking can play a part in determining bundles. Some styles require more bundles to achieve their distinctive look, especially those involving layered cuts or unique designs.

Remember: Your individual needs and preferences will always factor into calculating the right amount of bundles. It’s your sew-in after all. This guidance is not a foolproof method, but with careful consideration, you’re well on your way to a flawless sew-in that suits you.

Hair Length and Bundle Quantity

Getting the perfect look with a sew-in style boils down to your choice of hair length and the corresponding bundle quantity. This aspect of hair styling is paramount. It’s not just about covering your head with hair bundles. It’s about making sure that coverage is ample and proportional, giving you the desired fullness and balance.

Let’s dive into the specifics. If you’re looking to achieve a shorter hairstyle such as a bob, you’ll need fewer bundles compared to a long style. Generally, a hair length of 8″ to 14″ requires 2-3 bundles. However, longer wears such as 20″ to 30″ usually need 3-4 bundles. Why is this, you might ask? It’s pretty simple. Shorter bundles have more hair strands and are visually fuller. This fullness ensures that you’ll need fewer packs to achieve your desired look. In contrast, longer bundles have fewer hair strands – meaning you’ll need more bundles to match the density of shorter lengths.

8″ – 14″2 – 3 bundles
20″ – 30″3 – 4 bundles

It’s worth noting that these ranges are only guides. Your specific needs might vary depending on other factors like head size, desired volume, type of hair, and hairstyle preferences. For instance, if you’re going for a full-bodied, voluptuous look, you may need to throw in an extra bundle or two. This flow, this dance, is what makes calculating the right amount of hair bundles not just science but also an art. So, keep your unique needs and desired look in mind. Let them guide you as you decide the number of hair bundles you need for your perfect sew-in hairstyle.

Factors Influencing Bundle Count

When deciding “how many bundles do I need for a sew in,” it’s not only about hair length. There are several other key elements to consider that influence the quantity required for a flawless sew-in look. Head size, desired volume, hair quality, and hairstyle preference are among these significant factors.

Your head size plays a fundamental role in determining how many bundles you need. People with larger heads typically require more bundles than those with smaller heads, owing to the larger area that needs covering. Typically, it’s found that the average head size needs about 2-3 bundles for shorter lengths and 3-4 bundles for longer lengths.

Another pivotal factor is your desired volume. If you want a fuller look, you aren’t going to get it with the bare minimum. For voluminous and thick hairstyles, you’ll need a higher number of bundles. Nevertheless, for a natural look, fewer bundles will suffice.

Thirdly, hair quality is a crucial factor. Not all hair is created equal. The denser the strands, the fewer bundles you’ll need, as each bundle contains more hair. Conversely, for thin and light hair bundles, you might have to consider going for extra to meet your volume requirements.

Lastly, consider your intended hairstyle. As discussed earlier, sew-in bobs typically demand fewer bundles. However, hairstyles requiring more coverage — such as those with layers or textures — may require additional bundles for desired fullness.

To be sure you’re making the right call, it’s often a good idea to consult with a professional hairdresser before purchasing your bundles. While these general guidelines can provide a starting point, remember that every person’s individual hair needs are unique. Therefore, only a personalized approach will lead to the best results.


So you’ve learned that the number of bundles you need for a sew-in isn’t just about hair length. You’ve discovered that head size, your desire for volume, hair quality, and your hairstyle choice can all play a part. Remember, more bundles might be needed for larger heads or if you’re after a voluminous look. Denser hair can often get away with fewer bundles. And don’t forget, different styles may call for different bundle counts to achieve that perfect fullness. But don’t stress over it. Your best bet is to consult with a professional hairdresser. They can offer personalized advice to suit your unique hair needs. With their help, you’ll nail the perfect sew-in every time.
