How Many Bundles for a Sew-In? The Ultimate Guide by Hair Length & Style
Last updated Jan.28,2026
Key Factors That Determine Bundle Count
Hair Length
Hair length makes a big difference in how many bundles you need. The drooping effect of long hair visually weakens the fullness. So longer hair usually calls for more bundles to look full and thick, while shorter hair needs fewer.How Many Bundles for a Sew-In by Hair Length
Short Hair (8-14 Inches): You’ll need fewer bundles here. 2 bundles are just enough for a natural look.
Medium-Length Hair (16-22 Inches): This length needs more hair for a full style. 3 bundles are the ideal quantity to achieve a standard full finish.
Long Hair (24-30 Inches): Hair thins out at the ends with this length, so you need extra bundles to keep it full. We recommend 4 to 5 bundles to keep the hair thick from root to tip.
Desired Density & Volume
How thick and full you want your sew-in to be decides how many bundles you’ll use. a variable factor based solely on personal preference. If you just want a natural, slightly thick style, 2-3 bundles are enough. If you want super thick, full, and fluffy hair, add 1 more bundle than the basic amount. And if you’re going for an extremely full hairstyle, you’ll need to add 2 more bundles.Hair Texture
The different hair textures vary in fluffiness and support. So, it is a crucial factor that determines how many bundles you’ll need for a perfect sew-in.How Many Bundles for a Sew-In by Hair Texture
Straight Hair: This hair texture lies flat with volume, meaning you’ll typically need 3–4 straight bundles to keep the style full.
Wavy Hair: Compared to straight bundles, the wavy bundles create natural body and fullness. 3 bundles are sufficient to create a perfect sew-in.
Curly Hair: The Afro curly or kinky curly bundles are super thick and voluminous. The hair texture often requires the fewest bundles; 2-3 bundles can achieve a perfect effect.
Head Size
Head size is easy to miss, but it’s an important factor. The average head size is 22.5 inches. If your head is bigger, there will be more surface area to cover. You will need an extra bundle. It makes sure the hair covers your whole head evenly. If your head is smaller, you can use a few less bundles.Sew-In Style
Different sew-in styles require different numbers of bundles due to the different cover areas.How Many Bundles for a Sew-In by Style
Full Sew-In: A full head sew-in covers your whole head. It uses the most bundles, so you’ll need to follow the highest standard for how many to get.
Leave-out/partial Sew-In: These styles only cover a partial part of the head. You can reduce the bundle count according to how much area you want to cover.
Closure/Frontal Sew-In: When using a closure or frontal for your sew-in, you’ll need fewer hair bundles overall. The front sew-in requires fewer bundles than a closure sew-in.
2, 3, or 4 Bundles: Which Should You Choose?
2 Bundles: Suitable for short styles. Or you are planning for a partial sew-in. It might look thin if you use it for medium or long hair, though.
3 Bundles: The most popular option for naturalness and fullness. It works great with most lengths and textures. This is a safe go-for for a perfect sew-in.
4 Bundles: Pick this for long, lush, or super full hair. You’ll need it for lengths over 24 inches. It makes sure your hair is as thick as possible.
