How Many Packs of Bulk Hair Do I Need for a Full Head of Boho Braids?
Quick answer: most full boho sets need 4–6 packs of 100g bulk hair for mid-back length, 6–8 for waist length, and 3–4 for a bob. Your density and braid size move the number, so the practical rule is: measure your head, plan for your length, and keep one spare pack unopened.
This guide gives you a calculation you can run before you buy, the length and density table, and the two mistakes that make people over- or under-order.
Run the numbers before you buy
Instead of guessing, work backward from what a full set needs:
- Count your braids. A standard full head of small-to-medium boho braids is roughly 20–30 braids for a mid-back set, more for smaller braids.
- Know grams per braid. A medium boho braid uses about 10–12 grams of hair. Small braids use less; jumbo uses more.
- Do the math. 25 braids × 11 grams ≈ 275g of hair — so 3 packs of 100g covers it with room to spare.
Your braider may add or remove grams based on your density, so this is a starting figure, not a guarantee.
The length and density table
| Finished length | Fine hair | Normal density | Dense hair |
|---|---|---|---|
| Bob (shoulder) | 2–3 packs | 3–4 packs | 4–5 packs |
| Mid-back | 3–5 packs | 4–6 packs | 5–7 packs |
| Waist length | 4–6 packs | 6–8 packs | 7–9 packs |
These ranges assume 100g packs at 16–18 inch hair. If your packs are heavier or lighter, scale by the gram weight on the listing, not by pack count.
Why the texture changes the count
Deep wave and kinky curly take more space per gram than straight or water wave, because the curl adds volume without adding mass. A full set in a curly texture can look fuller with the same gram count, but you still need enough strands to cover each braid with the right amount of body.
On Ywigs, water wave bulk braiding hair and deep wave bulk braiding hair are sold as loose 100g bundles, so you can compare the volume and weight directly on the listing.
Three mistakes that wreck the count
- Following a fixed number. "5 packs" works for a specific head, not all heads. Your density and length change it.
- Buying by pack, not gram. If your seller’s pack is 60g instead of 100g, the count doubles. Always check the gram weight.
- Not keeping a spare. Running out mid-install means a color or texture mismatch at the end. One spare, unopened, is the cheapest protection.
When to ask a braider first
If you are booking an install, ask the braider how many grams they plan per braid and which length they recommend before you order. Some stylists prefer pre-separated pieces over bulk so each braid is more even — in that case, the pack count differs because the format changed. For a length-and-texture walkthrough, check how many packs of crochet hair for a full head, by length and texture.
A worked example with real numbers
Let’s run the full calculation once so the process is concrete. Say you want a mid-back boho set, normal density, and your braider plans 24 braids at 11 grams each. That is 264 grams of hair. At 100g per pack, you need three packs — and one more as your spare. That lands you at four packs total, which is the safe, comfortable order.
Now change one variable: your braider uses jumbo braids at 16 grams each. Twenty-four jumbo braids need 384 grams, so three packs is tight and four becomes the base order. That is why the gram math beats a fixed pack count — the same "full boho set" can need three or four or five packs depending on braid size.
Texture changes the volume, not just the feel. A curly texture takes more space per gram, so the same 264 grams of deep wave looks fuller than the same weight of water wave. Weight is the number you buy by; volume is what your braider sees. If you are choosing between deep wave bulk and water wave bulk, compare by grams, then let the curl decide the look.
Braid size changes the count more than length
Length gets the attention, but braid size is usually the bigger variable. Small feed-in braids use far fewer grams each, which means a long set of small braids can weigh less than a mid-back set of jumbo braids. If you are deciding between two styles, run both through the gram math before you order.
| Braid size | Grams per braid (approx.) | Braids in a full set |
|---|---|---|
| Small / feed-in | 6–8 g | 35–45 |
| Medium / standard | 9–12 g | 20–30 |
| Jumbo / large | 14–18 g | 12–18 |
Take a medium set as the baseline: 25 braids at 11 g is 275 g, or 3 packs with one spare. Switch to small feed-ins and the same grams buys 35+ braids, which is why a fine, intricate boho set can feel surprisingly light despite taking longer to install.
The 5-minute ordering cheat sheet
- Decide length first — bob, mid-back, or waist. This sets the gram-per-braid baseline.
- Pick braid size — small, medium, or jumbo — and estimate grams per braid from the table above.
- Count your braids — ask your braider or estimate 20–30 for a full medium set.
- Total the grams — braids × grams each = total needed.
- Divide by your pack weight — then round up one full pack as the spare.
One note on format: if your braider prefers pre-separated pieces over loose bulk, the counting unit changes from grams to pieces. In that case, how many packs of crochet hair for a full head, by length and texture lines up the piece-based math for you.
A color note before you order. If you want a multi-tone or ombre look, buy all bundles from the same dye lot and keep the spare from that same order. Hair dye lots shift slightly between batches, and a spare from a different lot can show at the ends. Buying one extra pack at the same time fixes this in advance.
Two math traps that change your order
The gram formula is simple, but two mistakes slip in at the last step and ruin the order.
- Forgetting to include the back. The front, crown, and nape each use different amounts of hair. If you calculate for the visible front section only, the set runs out at the back. Add a nape allowance of roughly one-quarter of your front-section total, or the thickness at the nape will tell on the finished set.
- Rounding down to save money. Dropping a pack because you are close to the boundary means a near-miss install. The rule that saves money in the long run is: when your total lands within half a pack of a boundary, buy the next one up. An unopened spare is returnable; a set that is short somewhere is not.
Both traps are about the same thing: the difference between the hair you can see and the hair the braider actually needs. Loose bulk shrinks in volume as it is tucked and styled, so a plan that is almost enough is, in practice, not enough.
FAQ: Packs of Bulk Hair for Full Boho Braids
How many packs of bulk hair do I need for full boho braids? Most full boho sets need 4–6 packs of 100g bulk hair for mid-back length, 6–8 for waist length, and 3–4 for a bob. The number shifts with your density and braid size.
Does boho braid density change how many packs I need? Yes. Higher density means more braids and more grams per braid. Dense hair often needs an extra pack; fine hair can usually drop one and still look natural.
How many grams of hair are in a pack? Common loose bulk braiding hair is sold as 100g per bundle, with strand count varying by texture. Always check the listing weight, because 100g of deep wave and 100g of kinky curly are not the same volume.
How long should the hair be for boho braids? Most boho sets use 14–20 inch hair, with 16–18 inch most common. Longer hair needs more packs because each braid carries more length.
Is it better to overbuy or underbuy for a full set? Buy one extra pack rather than running short, but keep it unopened so it can be returned. Running short mid-install wastes time and money.
