Length gets all the attention, but the number that actually decides whether your extensions look natural is the weight. Too few grams and the ends look thin and stringy against your own hair; too many and the set feels heavy, sits bulky at the roots, and is harder to hide. Here's how to read the gram count and pick the right fullness for your hair.
What "grams" actually measures
The gram weight of a clip-in set is the total weight of hair across all the wefts in the box — clips included, but the clips weigh almost nothing. It tells you how much hair you're adding, which is really a measure of volume. Two sets in the same length can look completely different if one is 120g and the other 200g.
Sandy Bella's regular clip-in sets come in two weights: 160 grams in 20 inches (a 7-piece set) and 200 grams in 24 inches (a 10-piece set). Both are 100% Remy human hair; the difference is how much hair you get and how long it is.
The quick answer by hair type
- Fine or thin hair: 160g is usually the sweet spot. It adds real length and fullness without overwhelming your natural hair or straining the roots. Fewer, lighter wefts are also easier to hide when there's less hair to cover them.
- Medium hair: either weight works. Choose 160g if length is the goal, and 200g if you want length and noticeably thicker ends.
- Thick or coarse hair: go for 200g. Thick natural hair swallows lighter sets — the extensions end up looking thinner than your own hair at the ends, which is the fastest way to give away that you're wearing them.
Why grams and length go together
Hair looks thinner the longer it gets. The same 160g spread over 24 inches looks noticeably wispier at the ends than 160g at 20 inches, because the weight is stretched over more length. That's exactly why our 24" set is 200g: the extra 40 grams keep the ends looking as full as the mid-lengths, so long hair still reads as healthy and thick rather than sparse.
If you're deciding between lengths, our length chart walks through 20" vs 24" by height and hair goal. Whichever you pick, the weight has already been matched to it.
Piece count matters too
Two sets can weigh the same and still wear differently depending on how the hair is divided. More pieces mean more placement options — the 10-piece 24" set includes narrower one- and two-clip wefts for the sides and around the face, which is where blending is hardest. The 7-piece 20" set is quicker to put in, which many customers prefer for everyday wear.
When to size up to 200g
- Your natural hair is thick, or you have a lot of it.
- Your hair is cut short or blunt and you need enough hair to hide the transition line.
- You wear high ponytails or updos, where the extension ends are on show.
- You want dramatic, "full glam" volume rather than a subtle boost.
When 160g is plenty
- Your hair is fine, thin, or has been thinning — heavier sets can pull on fragile roots.
- You mainly want length, with a natural amount of body.
- You'll wear the set daily and want something light enough to forget about.
Still unsure?
Pick the weight for your hair type first, then the length for your height, then the shade using our color-match guide. If you want extra fullness in just one spot — a thicker ponytail, or more hair around the face — the handmade Designer Collection 2-, 3-, 5- and 7-piece sets let you add volume exactly where you need it without a full second set.
