Determining the number of bundles for a sew-in is one of the most important steps for a successful install. However, if you are a sew-in beginner, you might be confused about the correct number of bundles. Here is a detailed breakdown to help you to get it right.
How Many Bundles Do You Need for a Sew-in？
Determining how many hair bundles/hair weaves are needed for a sew-in is a primary consideration for many people before getting the style done. The number of hair bundles required for a sew-in varies widely, ranging from 2 to 5 bundles. However, 3 bundles are the most common choice. The exact number will ultimately depend on individual circumstances.
Factors that Influence How Many Bundles You Will Use
1️⃣ Hair Length
Generally, the longer the hair, the more bundles are needed. This is because the weight of long hair causes the curls to be pulled and straightened, thus reducing their density. To maintain fullness from root to ends, more bundles are required.
14-24 inches: Usually 3 bundles.
26-30 inches: 4 bundles are recommended.
30 inches and above: 5 bundles are strongly recommended for an ultimate luxurious and voluminous long hair effect.

2️⃣ Expected Density and Volume
Natural/Medium Density: 3 bundles are sufficient; this is the most common choice.
Full/High Volume: 4-5 bundles are a safer option.
3️⃣ Hair Texture
Straight bundles: The texture is smooth and lies flat, so the density doesn't look as full as curly hair of the same density. Therefore, to achieve the same visual volume as curly hair, you may need to add an extra bundle.
Wave or curly hair: The texture naturally has more volume, so you may need slightly fewer bundles than straight hair of the same length. Usually, 3 bundles are sufficient.
4️⃣ Installation Method
Closure/frontal/leave-out: Because these designs only cover a portion of the head, not the entire head, fewer bundles are usually needed. Typically, 2-3 bundles are enough.
Full sew-in: For designs that cover the entire head, more bundles will be needed than the above.
5️⃣ Head Circumference
Small head:
14-24 inches: straight hair and wave hair for 3 bundles; curly hair for 2 bundles
26-30 inches: 4 bundles are recommended.
30 inches and above: 5 bundles are strongly recommended for an ultimate luxurious and voluminous long hair effect.
For a larger head circumference, we recommend adding one extra bundle, usually requiring 4 bundles in total.
Middle head size: 3 bundles are enough.
Large head size: For a smaller head circumference? You might be able to reduce it to 2 bundles.
