One of the most common wig-shopping frustrations: you order a 20-inch wig expecting it to be long, and it arrives shorter than you imagined. Or you order a 14-inch wig thinking it'll be a sleek shoulder-length style, and it falls above your shoulders. Wig length is measured differently from how we think about hair length in everyday life — and knowing how the numbers translate to your body makes all the difference.
How wig length is measured
Wig length is measured from the top of the cap (at the crown) down to the tips of the longest hair strands, with the hair pulled straight. This is the same way hair extensions and bundles are measured. The measurement is taken on the hair itself, not on your head or body.
This is important because the cap sits on top of your head, and your head adds height. A 20-inch wig doesn't mean the hair falls 20 inches from the top of your head — it means the hair strand is 20 inches long. The actual position on your body depends on where the cap sits (roughly at the crown) plus the 20 inches of hair below it.
The full wig length chart
All body positions below are approximate and based on an average height of 5’5″–5’6″. See the height adjustment section below if you're significantly shorter or taller.
| Length | Where it falls (average height) | Style category |
|---|---|---|
| 8 inches | Ear to chin — very short bob or pixie | Short |
| 10 inches | Chin level — classic chin-length bob | Short |
| 12 inches | Chin to jaw — longer bob, just above the neck | Short |
| 14 inches | Collarbone / top of shoulder | Short–medium |
| 16 inches | Mid-shoulder / shoulder blade top | Medium |
| 18 inches | Below shoulder / between shoulder and armpit | Medium |
| 20 inches | Chest / just below armpit | Medium |
| 22 inches | Upper chest / bust line | Medium–long |
| 24 inches | Mid-chest / sternum | Long |
| 26 inches | Lower chest / top of ribcage | Long |
| 28 inches | Waist / navel area | Long |
| 30 inches | Below waist / hip area | Extra long |
| 32–34 inches | Hip to upper thigh | Extra long |
| 36–40 inches | Mid to lower thigh | Extra long |
Short wigs: 8–14 inches
Short wigs range from pixie-adjacent (8 inches, falling around the ear) to collarbone-grazing (14 inches). This category is the most low-maintenance: shorter hair is easier to style, lighter to wear, and dries faster after washing. Short wigs also tend to be more affordable because they use less hair.
- 8–10 inches: Very short. Falls between the ear and chin. Classic bobs, pixie-inspired styles, structured cuts.
- 12 inches: Chin-length. The classic bob length — clean, chic, and versatile. One of the most popular lengths for first-time wig buyers.
- 14 inches: Collarbone. Sits at or just above the shoulder. Often described as “shoulder length” but technically hits right at the collarbone for most wearers.

Medium wigs: 16–20 inches
Medium lengths are the most popular range overall. They're long enough to feel luxurious and wear in multiple styles, but short enough to be manageable day to day. This is where the vast majority of bestselling wig styles live.
- 16 inches: Mid-shoulder. Below the shoulder but above the armpit. A comfortable, elegant everyday length.
- 18 inches: Between shoulder and chest. Flows naturally with movement — this length looks especially beautiful in body wave and loose wave textures.
- 20 inches: Chest level. Substantial length that looks clearly “long” but is still very wearable for daily use. One of the most popular lengths storewide.
Long wigs: 22–28 inches
Long wigs make a statement. At 22–28 inches, the hair falls from the upper chest down toward the waist. This range requires more care — longer hair tangles more easily and needs regular moisturizing — but the visual impact is significant. For wavy and curly textures, consider going up at least one density level (to 180%) to ensure the ends look full.
- 22–24 inches: Chest to sternum. Classic “long hair” territory. Versatile for styling — can be worn down, half-up, or in loose updos.
- 26–28 inches: Ribcage to waist. Approaching floor-length dramatic territory for shorter wearers. Very long and flowing, especially in straight and body wave textures.
Extra long wigs: 30–40 inches
Extra long wigs (30 inches and above) fall below the waist and can reach the mid-thigh or lower on average-height wearers. These are statement pieces — dramatic, editorial, and high-maintenance. They require consistent moisture, careful detangling, and gentle handling to prevent the ends from becoming dry and damaged.
- 30 inches: Hip level for most wearers.
- 32–34 inches: Upper thigh.
- 36–40 inches: Mid to lower thigh — approaching floor-length for shorter wearers.
At these lengths, 180–200% density is strongly recommended to prevent the ends from looking stringy.
How height affects wig length
The chart above is calibrated for an average height of 5’5″–5’6″. If you're shorter or taller, the same wig length will fall differently on your body:
| Your height | Adjustment |
|---|---|
| Under 5’2″ | Each length falls 1–2 inches lower on your body than the chart shows. A 16-inch wig that hits mid-shoulder on a 5’6″ person will hit below the shoulder on you. You may prefer shorter lengths to achieve the same look. |
| 5’2″–5’5″ | Slightly lower than chart. The positions above are still a reliable guide. |
| 5’5″–5’8″ | Chart is accurate for this range. |
| 5’9″ and above | Each length falls 1–2 inches higher on your body. A 20-inch wig that hits the chest on a 5’5″ person may only reach the armpit on you. Go one length longer to achieve equivalent coverage. |
Wavy and curly texture shrinkage guide
Curly and wavy wigs have natural shrinkage — the hair is measured straight but wears shorter because the curls and waves pull the length up. Here's how much shorter to expect each texture to appear:
| Texture | Shrinkage (approximate) | Example |
|---|---|---|
| Straight | None | 20″ measured = 20″ worn |
| Body wave | 1–2 inches | 20″ measured ≈ 18–19″ worn |
| Loose wave | 2–3 inches | 20″ measured ≈ 17–18″ worn |
| Deep wave | 3–4 inches | 20″ measured ≈ 16–17″ worn |
| Water wave | 3–4 inches | 20″ measured ≈ 16–17″ worn |
| Burmese curly | 4–6 inches | 20″ measured ≈ 14–16″ worn |
| Kinky curly | 6–8 inches | 20″ measured ≈ 12–14″ worn |
How to choose the right length
Think about where you want the hair to fall on your body
Use the chart above to identify the body position you want, then match it to the length. If in doubt, go one inch longer — it's much easier to trim a wig slightly than to wish it were longer.
Add shrinkage for curly and wavy textures
If you're ordering a wavy or curly wig, use the shrinkage guide above to size up appropriately. A curly wig ordered at your target length will appear shorter when worn.
Consider your lifestyle
Longer wigs are more dramatic but require more maintenance. If you want an easy daily wig, 16–20 inches is the sweet spot for most people — long enough to look luxurious, short enough to manage easily.
Consider your face shape and proportions
Longer wigs can elongate the face; shorter bobs can add width. If you're not sure what works for your face shape, see our face shape guide.
Go longer if you want styling options
Longer wigs can be trimmed or styled into shorter looks. Shorter wigs cannot be made longer. If you're between two lengths, go longer.
Short wigs (8–14″) | Medium wigs (16–20″) | Long wigs (22–28″) | Bob wigs | All wigs
Frequently asked questions
What does a 20-inch wig look like?
On an average-height person (5’5″–5’8″), a straight 20-inch wig falls to approximately chest level — just below the armpit. On a wavy texture, expect it to appear 1–2 inches shorter; on a curly texture, 4–6 inches shorter.
What is the most popular wig length?
18–22 inches is the most popular range. It's long enough to look luxurious and style in multiple ways, but manageable enough for everyday wear. 20 inches is the single most popular length across most wig collections.
What length looks most natural?
There's no single “most natural” length — it depends on your natural hair length and personal style. Many wearers find that choosing a wig in a similar range to their natural hair (or slightly longer) looks most seamless.
Are wig lengths the same as extension lengths?
Yes — wig lengths and bundle/extension lengths use the same measurement system. A 20-inch wig and a 20-inch bundle of hair have the same strand length when measured straight.
How do curly wigs measure differently?
Curly wigs are measured with the hair pulled straight, but they wear shorter because the curls create shrinkage. See the shrinkage guide above for specific estimates by texture.
What length wig is best for beginners?
14–18 inches is the most beginner-friendly range. Shorter wigs are easier to manage and less likely to tangle; medium lengths give you the flexibility of styling without the upkeep demands of very long hair.
