20 Inch Hair Handbook Lengths, Hairstyles, And Extensions

In everyday salon work, 20 inch hair is usually the first length where clients stop asking, “Is this long enough?” and start reacting to the change they see in the mirror. The difference feels immediate not just visually, but emotionally.. At this length, hair no longer looks “just slightly longer” it creates a clear visual transformation.

In real salon settings, this is often the first length where clients say, “Now it actually feels long.” When worn straight, 20 inch hair flows confidently down the back. When styled wavy or curly, it delivers volume, movement, and presence that shorter lengths simply cannot replicate.

At Great Hair, we work closely with salon owners, stylists, and wholesale buyers across the US, UK, and EU. And consistently, 20 inch hair ranks among the best-selling long lengths. It is commonly chosen as an upgrade from 16 or 18 inches, offering noticeable length without pushing maintenance or cost too far.

This guide breaks down what 20 inch hair actually looks like in real use not just on charts or product photos, but on real clients, across different textures, installations, and expectations.

20 Inch Hair Length

How Long Is 20 Inch Hair?

So, how long is 20 inch hair exactly?

• 20 inch hair ≈ 50–51 cm
• Measured from root to tip when fully stretched straight
• This is the industry-standard measurement used for wigs, bundles, and hair extensions

When suppliers list 20 inches hair, 20 inch hair length, or 20 inches of hair, they are always referring to this stretched measurement even though the hair may appear shorter once installed due to texture or styling.

From our experience handling both salon orders and wholesale shipments, most “length complaints” are not quality issues at all. They usually come from buyers not realizing that 20 inches is measured fully stretched not how the hair appears once installed or styled. In our experience, expectation mismatch usually comes from texture shrinkage, not quality issues.

How Big Is 20 Inches in Real Life?

When clients ask “How big is 20 inches in real life?” they are usually trying to visualize where the hair falls on the body.

On most wearers, 20 inch hair:

• Falls past the upper back
• Reaches mid-back or slightly below
• Creates an obvious long-hair effect from both side and back views

Compared to 18 inch hair, the difference is immediately noticeable especially in mirrors, photos, and video content. That visual jump is exactly why many clients upgrade from 18 to 20 inches. It’s the first length that consistently reads as “long” in mirrors, photos, and video especially in before-and-after salon content.

From a salon marketing perspective, 20 inch hair also photographs extremely well, making it ideal for before-and-after content, transformations, and social media reels.

What Does 20 Inch Hair Look Like on the Body?

How 20 inch hair length appears depends on three main factors:

• Texture
• Density
• Installation method

Straight textures show length most clearly, while wavy and curly textures trade some visible length for volume and movement.

Straight vs Wavy vs Curly How Texture Affects 20 Inch Hair

Straight 20 Inch Hair

• Typically falls at mid-back
• Shows the full 20 inch length clearly
• Creates a sleek, elongated silhouette
• Popular for wigs, tape-ins, sew-ins, and clip-ins

Straight 20 inch hair is ideal for clients whose priority is maximum visible length and polish.

Wavy 20 Inch Hair

• Appears closer to 18–19 inches visually
• Adds softness and natural movement
• One of the most requested textures in US & UK salons
• Excellent for everyday wear and luxury installs

Wavy textures are often chosen by clients who want long hair without a flat or overly sleek finish.

Curly 20 Inch Hair

• Appears shorter due to natural shrinkage
• Emphasizes volume and shape rather than length
• Best for bold, textured, statement looks

Texture is also where expectation gaps happen most often. Clients who expect 20 inch curly hair to fall mid-back usually end up disappointed not because of quality, but because curl shrinkage wasn’t explained clearly upfront.

Braid Length Chart: How 20 Inch Hair Performs in Braided Styles

Braiding naturally reduces visible length due to overlap.

For box braids, knotless braids, and cornrows, 20 inches offers a balanced combination of length, weight, and movement.

Who Should Choose 20 Inch Hair Extensions?

20 inch hair extensions are ideal for:

• Clients familiar with wigs or extensions
• Buyers seeking elegant, feminine long hair
• Salons offering transformation services
• Wholesale buyers serving US, UK, and EU markets

Real salon insight:
For clients around 160–165 cm tall, 20 inch straight hair typically reaches mid-back. Wavy textures appear slightly shorter but feel fuller and more dimensional.

When 20 Inch Hair Is NOT the Right Choice

20 inch hair may not be suitable if:

• The client is completely new to extensions
• Minimal maintenance is the top priority
• Short or lightweight styles are preferred
• Daily styling time is very limited

In these cases, 16 or 18 inch hair often delivers better satisfaction.

“20 inch hair is where clients start to see a true transformation without entering high-maintenance territory. From a wholesale perspective, it’s one of the most stable, repeat-order lengths we supply.”
