Hair Length Chart: Find the Perfect Extension Length for You

Picking the right length for your hair extensions isn’t always as simple as choosing a number. Depending on your hair type and the look you’re going for, the same length can appear very different. That’s where a Hair Length Chart comes in handy—it gives you a realistic idea of how each length looks in real life.

In this guide, Raw Hair will walk you through how to choose the perfect extension length based on your hair texture, style, and lifestyle.

What is a Hair Length Chart?

A hair length chart is a helpful visual guide that shows how different hair lengths look on the body – like where 10 inches or 20 inches of hair might fall, from chin-length to waist-length and beyond. It’s especially useful when you’re choosing a new haircut, planning to grow your hair out, or picking hair extensions. With this chart, you can easily picture the length you want and make sure you and your stylist are on the same page.

Different Hair Length Charts

Hair length can look very different depending on the texture – straight, wavy, or curly. That’s why using a hair length chart by hair type is essential when choosing extensions. Even if two bundles are measured the same in inches, their visual length can vary greatly due to the curl pattern.

Straight Hair Length Chart

Straight hair shows the truest representation of length. Because there’s no wave or curl to reduce its visible size, what you see is what you get.

Wavy Hair Length Chart

Wavy hair has a natural “S” pattern that adds volume but slightly reduces the visible length. When measured stretched, it’s equal to straight hair – but appears shorter when worn.

Curly Hair Length Chart

Curly hair shrinks the most. The tighter the curl, the shorter the hair appears. Even though it’s measured the same way – fully stretched – its coiled shape can make it look several inches shorter.

Hair Type	Measured Length	Appears As
Straight	True to length	True to length
Wavy	Pulled straight	~2 inches shorter
Curly	Pulled straight	~4 inches shorter

How to Measure Hair Extensions

To get the most accurate idea of what hair length you’re buying, it’s important to measure hair extensions correctly. The standard method is to measure the length of the hair when it’s straight, regardless of the texture.

If you’re buying wavy or curly extensions, keep in mind that the hair is first pulled straight to determine its true length. This means that a 20-inch curly bundle will appear significantly shorter than a 20-inch straight bundle once worn.

Here’s how to measure them:

• Straight Hair: Simply measure from the top of the weft or bond down to the very tip.
• Wavy or Curly Hair: Gently stretch the hair straight and measure from top to end.
• For clip-ins or bundles: Lay the hair flat on a surface, smooth it out, and use a tape measure from root to tip.

Understanding this helps set the right expectations and ensures you pick the right length for your desired style – especially when mixing different textures or layering.

Tips for Choosing the Right Hair Length

Choosing the right hair length can make all the difference in how natural and flattering your extensions look – so before you buy, take a moment to check out these simple tips to find the perfect match for you.

Consider Your Natural Hair Length

If you want your extensions to blend seamlessly, it’s best to choose a length that’s 4 – 6 inches longer than your natural hair. This keeps the final result looking natural – especially if you don’t plan to trim or layer the extensions.

Think About Your Hair Texture

As we mentioned in the hair length charts, wavy and curly textures appear shorter than straight ones. So if you want your curly hair to look like it reaches mid-back, you may need to go up a few inches in length.

Match It to Your Lifestyle

Long hair looks glamorous, but it can require more care. If you’re active, often on the go, or prefer low-maintenance hair, medium lengths (16–20 inches) might be more practical than very long styles.

Still feeling unsure about the right hair length for your extensions? You’re not alone – and that’s exactly why we’re here. Choosing the perfect length can make all the difference in how natural and flattering your final look turns out.
