How Many Grams of Clip-In Extensions Do I Need?
One 125 g set of 22-inch clip-ins is right for fine to medium hair. If your hair is medium-thick or thick, plan on 2 sets (250 g): longer extensions need more grams so the ends don't look thinner than your own hair.
"How many grams do I need?" is the first question almost everyone asks us, and the honest answer depends on two things: how thick your own hair is, and how long the extensions are. Our set is 22 inches long and weighs 125 grams. Here's how to tell whether one set is enough for you, or whether you'll want two.
The short version: 1 set or 2?
| Your hair | You mostly want length | You want length and volume |
|---|---|---|
| Fine ponytail under about 2 inches around | 1 set (125 g) | 1 set (125 g) |
| Medium ponytail about 2 to 3 inches around | 1 set (125 g) | 2 sets (250 g) |
| Thick ponytail over about 3 inches around | 2 sets (250 g) | 2 sets (250 g) |
Fine hair rarely needs two sets even for volume, because fine hair has less to anchor the extra clips and more hair can start to look heavy at the roots.

Which do I need?
No tape measure? Wrap a regular hair tie around your ponytail. If it goes around three or more times easily, your hair is probably fine. Two times, medium. If it barely goes around twice, thick.
Why longer extensions need more grams
Grams measure weight, not fullness. A 22-inch strand of hair weighs more than a 16-inch strand, so 125 grams of 22-inch hair contains fewer strands than 125 grams of shorter hair. Fewer strands means the ends look thinner. That's why the same weight that looks thick at shoulder length can look lighter at 22 inches, and why people with thick hair usually need more grams to match their own ends.
What other brands recommend, and why the charts disagree
Published charts for full-head clip-ins at around 20 to 22 inches usually land in these ranges:
- Fine hair: roughly 100 to 120 grams
- Medium hair: roughly 130 to 160 grams
- Thick hair: roughly 160 to 220 grams or more
Some brands go as low as 50 to 80 grams for fine hair, but those are volume pieces, not full sets for length. Others recommend 160 grams or more even for thin hair at 20 inches. The difference is mostly about the goal: a little volume, or a full head of long hair. So where does 125 grams sit? At 22 inches, it's on the lighter side of full-head sets. That's great for fine to medium hair and for comfort, and it's why we tell anyone with thick hair to plan on two sets instead of being disappointed by thin-looking ends.
What's in one set
| Weft | Width | Clips | How many | Usually goes |
|---|---|---|---|---|
| Wide | 9 inches | 4 | 1 | Across the back of your head, at about the top of your ears |
| Medium | 6 inches | 3 | 2 | One at the nape, one higher toward the crown |
| Small | 3.5 inches | 2 | 2 | Each side of your head, above the ears |
| Mini | 1.5 inches | 1 | 2 | Near your temples or anywhere that needs filling in |
That's 7 wefts and 16 clips, 22 inches long, 125 grams in total, with a lace lining on each weft. Our step-by-step placement guide has a map of where each one goes.
When two sets make sense
- Your hair is thick and your ends are full. One set would make your extensions look thinner than your own hair.
- You want big, full styles like quinceañera curls, wedding waves or a very full high ponytail.
- Your hair is medium and you want both length and volume.
With two sets, place the second set's wefts in the gaps between the first set's rows, and use the extra side pieces where your hair looks thinnest. You don't have to wear all 14 wefts. Many people wear about 10 and keep the rest for special occasions. Two sets are $398.
When one set is plenty
- Your hair is fine to medium.
- You want length more than volume.
- Your own hair is at least chin length. Shorter than that, blending gets harder at any weight.
One set is $199.
Comfort: can you wear too much?
More hair means more weight on your roots. Wear extensions for the day and take them out at night, and give your hair breaks. If your scalp aches, you get headaches, or you feel pulling, take them out. The American Academy of Dermatology warns that styles that pull on hair for long periods can lead to hair loss (traction alopecia), so comfort isn't just about feel.
Frequently asked questions
Is 125 grams enough for a full head?
For fine to medium hair, yes: 125 g gives a full, natural look at 22 inches. For thick hair, 125 g usually leaves the ends looking thinner than your own hair, so most people with thick hair use 2 sets.
Can I wear only part of the set?
Yes. Many people with fine hair wear 5 of the 7 wefts on everyday days and save the small 1.5 inch pieces for when they want extra fullness.
Is two sets too heavy?
250 g is the amount most brands recommend for thick hair at this length. If your scalp feels sore, take a break and wear fewer wefts. Pain is a sign to take them out.
Should I get 2 sets of the same shade or 2 different shades?
Usually the same shade. Two different shades can help if your hair has highlights or you're between shades, but only if both are close to your ends.
How do I know if my hair is fine, medium or thick?
Gather your hair into a ponytail at the back of your head and measure around it with a tape measure: under about 2 inches is fine, 2 to 3 inches is medium, over 3 inches is thick.
