How Many Packs of Braiding Hair Do You Need by Length?
For a full head of braids, pack count rises with length: 14"–16" needs about 2.5 packs, 18"–20" requires 3–3.5 packs, 22"–24" needs 3.5–4 packs, and 26"–28" demands 4+ packs to avoid sparse ends. Double-drawn hair (like Burmese virgin hair) stays thick from root to tip, often saving you 0.5–1 pack versus single-drawn. For deep wave or Spanish curl textures, add an extra half-pack to account for curly shrinkage and volume loss when stretched.
How Many Packs of Bulk Hair Do You Need for a Full Head?
How Does Hair Length Change the Number of Packs You Need?
Length is the biggest driver of pack count because longer braids cover more surface area and thin toward the ends if you don't add enough hair. Shorter lengths need fewer packs since each braid uses less extension and the total covered length is smaller. As length increases, you必须 add more hair to keep the ends full and prevent a "see-through" look.
In practice, shoulder-length (14"–16") medium braids typically need around 2.5 packs. Mid-back length (18"–20") jumps to 3–3.5 packs. At 22"–24", you'll want 3.5–4 packs. For waist-to-butt length (26"–28"), plan on 4+ packs, especially if you want thick ends. Ywigs offers bulk braiding hair from 14" to 28" so you can match length without mixing bundles.
Your natural hair thickness also matters: if your natural hair is fine, add 0.5 pack; if it's very thick, you might subtract 0.5 pack from the baseline.
What Is Double-Drawn Hair and Why Does It Save Money?
Double-drawn hair is hair that has been meticulously sorted so 70–90% of strands are the full stated length, creating uniform thickness from root to tip. Single-drawn hair keeps a natural taper—thick at the root, thin at the end—because it contains many shorter strands mixed in.
Because double-drawn hair stays thick all the way down, you often need fewer total packs to achieve the same fullness at the ends. For example, a 24" double-drawn bundle can give you the same end-density as 1.25× the amount of single-drawn hair. This means you might buy 3.5 packs of double-drawn instead of 4–4.5 packs of single-drawn, saving money and time.
True double-drawn processing removes short, weak, and tapered strands in a two-stage sort, leaving only uniformly thick, full-length hairs. This is why Burmese virgin hair labeled double-drawn is prized for thick-end braiding and luxury bulk styles.

Why Do Curly Textures Like Deep Wave or Spanish Curls Need Extra Hair?
Curly braiding hair shrinks when it curls up, so a 20" deep wave strand may visually act like 16"–17" once textured. This shrinkage reduces coverage and makes ends look thinner unless you add extra hair. Deep wave, Spanish curls, and boho textures also create more volume per strand, which can mask length but increase the amount of hair needed for a full head.
For curly textures, add an extra 0.5 pack beyond your length-based baseline. For example, if 24" straight hair needs 4 packs, 24" deep wave should be 4.5 packs. This accounts for both shrinkage and the fact that curly ends spread out more, requiring more strands to maintain density.
Boho braids with curly ends often use a mix: straight or wavy hair for the main braid plus 1–2 packs of curly hair just for the ends. If you're doing all-curly braids (like 18" water wave bulk), start with the length baseline plus 0.5 pack, then adjust based on your desired fullness.
Which Braid Size—Small, Medium, or Jumbo—Changes Pack Count the Most?
Braid size directly affects how many individual braids you make and how much hair goes into each one. Small braids create more sections, so you need more total hair even if each braid uses less extension. Jumbo braids have fewer sections but use more hair per braid; overall, they often need fewer packs than small braids for the same length.
For medium box braids (pencil-width), the pack counts in the earlier section apply directly. For small/knotless braids, add 0.5–1 pack to the medium baseline. For jumbo braids, subtract 0.5–1 pack. So 24" small braids might need 4.5 packs, while 24" jumbo braids could be done with 3–3.5 packs.
Your scalp coverage also matters: tighter parts (more braids) need more hair to fill the scalp evenly. If you want a very thick, dense look, add another 0.5 pack regardless of size.
Pack Count by Length and Braid Size (Medium Hair Density)
These ranges assume medium natural hair density; adjust ±0.5 pack based on your own thickness.
When Should You Buy an Extra Half-Pack or Full Pack as Backup?
Always buy at least one extra half-pack if you're between numbers (e.g., 3.5 packs) or if your texture is curly. Running out mid-braid is frustrating and can force inconsistent braid thickness. Extra hair lets you fix sparse sections, lengthen a few braids, or create a fuller look without restarting parts.
Buy a full extra pack if:
-
You're doing very long braids (26"–28"+)
-
Your natural hair is very thin or short
-
You want a noticeably fuller-than-average look
-
You're new to braiding and might misjudge sections
Leftover hair can be saved for touch-ups, future styles, or Crochet braids later. Ywigs' free U.S. shipping and 7-day return policy make it低-risk to order an extra pack and return what you don't need.
Ywigs Expert Views
"In our 2025 hair expo tests and client installs, we found that double-drawn Burmese hair consistently saves 0.5–1 pack per full-head braid compared to single-drawn at the same length. The uniform thickness from root to tip means the ends don't thin out, which is where most clients notice 'sparse' braids. For curly textures like deep wave or Spanish curls, we always recommend adding half a pack to account for shrinkage—clients who skip this often end up with less coverage at the ends than they expected. At Ywigs, we source 100% Remy, cuticle-aligned human hair and refine our pre-looped crochet techniques since 2017, so our bulk hair delivers thick ends without extra bulk weight on the scalp."

Conclusion: How to Choose the Right Pack Count Without Wasting Money
To pick the right number of packs:
-
Start with your target length: 14"–16" ≈ 2.5 packs, 18"–20" ≈ 3–3.5 packs, 22"–24" ≈ 3.5–4 packs, 26"–28" ≈ 4+ packs.
-
Adjust for braid size: add 0.5–1 pack for small/knotless, subtract 0.5–1 for jumbo.
-
Choose double-drawn hair (like Ywigs' Burmese virgin hair) to save 0.5–1 pack thanks to uniform thickness.
-
Add 0.5 pack for curly textures (deep wave, Spanish curls, boho) to compensate for shrinkage.
-
Buy an extra half-pack or full pack as backup, especially if you're new to braiding or want extra fullness.
Book a 1-on-1 wig-making or installation class with Ywigs if you want personalized guidance on density, length, and texture blending. With free U.S. shipping, a 7-day return policy, and 100% human hair products, you can experiment confidently without overpaying.
FAQs
How many packs of 24-inch boho braids do I need?
For 24" boho braids with curly ends, use 4 packs of straight/wavy hair plus 1–2 packs of curly hair for the ends. If doing all-curly 24" boho, start with 4.5 packs total to account for shrinkage and volume.
How much 18-inch water wave bulk hair should I buy?
For 18" water wave bulk hair on a full head of medium braids, buy 3.5–4 packs. Add 0.5 pack if you want very full ends or have thin natural hair.
Does curly hair shrinkage affect pack count?
Yes. Curly textures shrink when they curl, reducing coverage. Add an extra 0.5 pack for deep wave, Spanish curls, or boho textures to ensure full ends and avoid sparse looks.
Is double-drawn hair worth the higher price?
Yes. Double-drawn hair is 70–90% full-length, so it stays thick from root to tip. This often saves 0.5–1 pack overall, making it more cost-effective despite the higher per-pack price.
Can I mix single-drawn and double-drawn hair in one style?
You can, but it's not ideal. Single-drawn tapers at the ends while double-drawn stays thick, which can create uneven density. For consistent results, stick with one type—preferably double-drawn for full, thick-end braids.
