How Many Bundles Do I Need? A Simple Guide by Length and Style
Buying too few bundles leaves a sew-in looking thin, and buying too many wastes money. If you are asking how many bundles do I need, the answer depends on three things: the length you want, whether you use a closure or frontal, and how much each bundle weighs. This guide makes it simple.
Quick chart: bundles by length
This is a general guide for a full head, based on bundles of about 100g each. Thicker hair, a fuller look or curly textures may need one more.
| Length | With a closure or frontal | Without a closure (leave out) |
|---|---|---|
| 8 to 14 inch | 2 to 3 bundles | 3 bundles |
| 16 to 20 inch | 3 bundles | 3 to 4 bundles |
| 22 to 26 inch | 3 to 4 bundles | 4 bundles |
| 28 inch and longer | 4 bundles | 4 to 5 bundles |
Why longer hair needs more bundles
A bundle's weight stays about the same whatever its length, so longer bundles spread the same amount of hair over more length. That makes the ends look thinner. Adding a bundle keeps long styles full from root to tip.
Check the bundle weight in the listing
Not every bundle weighs 100g. Some lighter bundles are sold at 50g to 85g, so you may need more of them for the same fullness. Always check the weight shown in each product listing before you count your bundles.
Closure, frontal or leave out?
- Closure (4x4, 5x5): covers the top of your head, so you need fewer bundles and none of your own hair is left out.
- Frontal (13x4, 13x6): covers the whole hairline from ear to ear, so you need fewer bundles and can wear more parting styles.
- Leave out: some of your own hair blends with the bundles at the front, so you usually need an extra bundle.
Not sure which to pick? Read bundles with closure vs frontal.
Mixing lengths
Many people buy bundles in different lengths, for example 18, 20 and 22 inch, to get natural layers. Put the longest bundles at the bottom of the head and the shorter ones near the top. Popular 3-bundle sets include 24 26 28 and 26 28 30 inches, for example in our 99J burgundy bundles.

Frequently asked questions
Are 3 bundles enough for a full head?
For most lengths up to about 20 inches with a closure or frontal, 3 bundles of around 100g are usually enough. Go up to 4 for longer or fuller styles.
How many bundles do I need for 30 inch hair?
Plan for about 4 bundles with a closure or frontal, and 4 to 5 without one.
Do curly bundles need more hair?
Curly hair looks fuller, but it also looks shorter. Many people choose the same number of bundles but go a few inches longer.
Should all my bundles be the same length?
Not necessarily. Mixing lengths gives natural layers. Keep the same length if you want a blunt, one-length look.
