Density measures how much hair is ventilated onto the cap. It changes the look, the weight and the price — so it is worth choosing deliberately.
130% — light and natural
Mimics fine to medium natural hair. Light on the head and the most affordable, but can look thin in longer lengths. Good for short bobs.
150% — the everyday standard
Looks like healthy, full natural hair. Our default recommendation for lengths up to 20 inches and for anyone who wants a believable everyday look.
180% — full and glam
Noticeably voluminous, holds curls and waves beautifully, and photographs well. The most popular choice for 22 inches and up, and for body wave and deep wave textures.
200% — maximum volume
Red-carpet fullness. Stunning for special occasions and very long lengths, but heavier and hotter to wear daily.
How length changes the math
The same density looks thinner as length increases, because the hair is spread over more inches. A 24-inch wig at 150% can look sparse; at 180% it looks lush. If you are buying 26 inches or more, choose 180–200%.
Quick answer: 150% for short and medium everyday wigs, 180% for anything 22 inches or longer, 200% when you want drama.
