You're about to place your order. You've picked the texture, chosen your length and then it hits you: how many bundles do I actually need? Order too few and your stylist is calling you mid-install. Order too many and you're sitting on $200 worth of hair you don't know what to do with.
We built this guide to give you the exact number for sew-ins, human hair bundles with closure, quick weaves, and deep wave installs. No guessing. No waste. At Snapped Hair, every bundle we sell is 100% raw Brazilian hair, so we know exactly how our hair performs across every install type.
What Bundle Inches Mean (and Why It Changes Your Count)
Before the numbers, you need to understand what you're buying. Bundle inches refer to the length of the hair strand when pulled straight. That number changes everything about how many types of hair bundles you need for your install.
Here is what each length actually looks like on the body:
- 10"–14": Above the shoulder to shoulder-length
- 16"–18": Collarbone to chest
- 20"–22": Mid-chest to bra strap
- 24"–26": Waist
- 28"–30": Hip to low hip
- 30"+: Floor-grazing
The longer the bundle, the more hair it takes to cover the same area from root to tip. That is why you need more bundles at 28 inches than at 18 inches, not because your head got bigger, but because the hair has to travel further down.
How Many Hair Bundles for Sew In?
This is the most searched question in hair, and the answer depends on three things: your length, your texture, and whether you're using a closure or going with a leave-out.
Here is the count most stylists work with for hair bundles for a sew in:
|
Hair Length |
No Closure |
With Closure |
With Frontal |
|---|---|---|---|
|
8"–14" |
2–3 bundles |
2 bundles |
1–2 bundles |
|
16"–20" |
3 bundles |
2–3 bundles |
2 bundles |
|
22"–26" |
3–4 bundles |
3 bundles |
2–3 bundles |
|
28"–30"+ |
4–5 bundles |
3–4 bundles |
3 bundles |
A few things that shift this count:
Your braid for sew in matters– The braid pattern determines how much of your scalp needs to be covered. If you are doing a leave-out, your stylist needs to blend your natural hair at the part, that takes an extra bundle at longer lengths to avoid thin spots.
2 bundles of hair works at shorter lengths– If you are doing a sew in at 14 to 16 inches with a closure, 2 bundles covers the back and sides cleanly. At 18 inches or longer without a closure, 2 bundles will look thin, go to 3.
Curly textures need one extra bundle– Deep wave, Caribbean curl, and kinky curl have more volume per inch than straight or loose wave. Budget one extra bundle at every length or you will run short.

How Many Human Hair Bundles with Closure Do You Need?
Using human hair bundles with closure is the smartest way to order, and it almost always means you need fewer bundles overall.
Here is why: a closure covers the crown of your head so your stylist does not need to sew bundles across that area. You save a bundle, protect your edges, and get a cleaner part.
Closure with bundles count by length:
- 8"–14": 2 bundles + closure
- 16"–20": 2–3 bundles + closure
- 22"–26": 3 bundles + closure
- 28"+: 3–4 bundles + closure
The difference between a 4x4 and 5x5 closure is coverage, the 5x5 gives you more parting space but it does not change your bundle count. Either closure reduces your overall order by one bundle compared to a no-closure install.
Closures and bundles should always be matched. Same texture, same donor, same wave pattern. Mixing textures from different brands is how you end up with a noticeable contrast line. Our closures are sourced to match our bundles so the blend is seamless from day one.
Deep Wave Sew In with Closure
Deep wave is the texture most likely to trip people up on bundle count. Because the curl pattern is tight and full, a deep wave sew in with closure uses hair differently than a straight or loose wave install.
At 18 to 22 inches: go with 3 bundles plus a closure instead of 2. At 24 inches and up: plan for 4 bundles plus a closure. Raw deep wave holds its curl permanently because the wave is natural, not chemically created, so the density you see in the bundle is the density you get install after install.
How Many Quick Weave Bundles Do You Need?
A quick weave is a different install method- hair is bonded to a cap rather than braided and sewn, but the bundle count is similar to a standard sew-in.
Quick weave bundles by length:
- 10"–16": 2 bundles
- 18"–22": 2–3 bundles
- 24"+: 3 bundles
The main difference: quick weaves do not require a braid base, so there is no leave-out calculation to worry about. The cap covers the crown, which means you do not need an extra bundle for scalp coverage. Straight and body wave textures work best, curly textures are harder to cap-bond evenly and can look uneven at the roots.
One thing to plan for: quick weave hair is typically not reusable after removal. If longevity matters to you, a sew-in with raw bundles will outlast a quick weave install every time.
Frequently Asked Questions
How many bundles of weave do I need for a full head?
For a full head sew-in with no closure or frontal, plan for 3 bundles at 16 to 20 inches and 4 bundles at 22 to 26 inches. Using a closure drops that count by one bundle. Curly textures like deep wave need one extra bundle at every length due to volume.
Can you do a sew in with 2 bundles?
Yes, at lengths up to 16 inches with a closure. The closure covers the crown, so 2 bundles handle the back and sides completely. At 18 inches or longer without a closure, 2 bundles will look thin. If your stylist is telling you to grab a third, listen to her.
What do bundle inches mean?
Bundle inches refer to the length of the hair strand when pulled straight. 16 inches sits around the collarbone, 22 inches hits mid-chest, and 28 inches reaches the hip. The longer the bundle, the more bundles you need per install because the hair has further to travel.
What types of hair bundles are there?
Bundles come in straight, body wave, loose wave, deep wave, and kinky or curly textures. Raw bundles are collected from a single donor and never chemically altered, the texture is natural and permanent. Virgin bundles are unprocessed but may come from multiple donors. Processed bundles have a chemically created texture that fades after a few washes. Snapped Hair sells raw bundles only.
Where can I find closure and bundle deals?
Our bundle deals collection has pre-paired sets, bundles and closures matched by texture and length so you are not mixing and hoping for the best. Sets start at 2 bundles plus a closure and go up from there.
