Hairstyles allow us to change our looks and personalities effortlessly. With the birth of hair extensions, people can easily have the hairstyles they want without cutting or changing their hair colors. However, you need to consider specific hair extension lengths that will fit the look that you want.

So, hold up, don't buy those hair extensions that you are eyeing yet without checking their lengths first! Here's how to do it.

What are the standard hair lengths?

If you are new to using hair extensions, you might feel that it's hard to determine how many inches your hair is without measuring them. But to the professionals, they can quickly tell how long your hair is.

Natural Hair Length

16 – inchShoulder-length hair.
18 – inch
Hair length is just below the shoulder.
22 – inch
Bra-length, or it reaches the middle part of your back.
24 – inch
Hair length is just below the middle part of your back.

For those who have thin hairs, extra short hairs, and haircuts like a cropped cut or pulled back hair, you may need extra help for the extension to hold into your hair for the hair extensions to look natural.

Hair Length Chart

To avoid confusion and misunderstanding when referring to hair lengths, the hairstylists and hairdressers created a hair length chart to determine the length of the hair quickly.

Short-length Hair

For your hair to be classified as short hair, the length must be around 6 inches to 12 inches. Or, it should run just above your ear down to your chin. Some short hairstyles and cuts include bob cut and pixie cut.

Medium-length Hair

This hair length is the most common list, as you can easily dress it up through extensions and highlights. Medium-length hair, or most widely known as shoulder-length hair, which is around 14 inches to 22 inches, can make you look classic and trendy at the same time.

Long-length Hair

Long hairs represent beauty, femininity, class, elegance, and fashion all at once. With a hair length of at least 24 inches to 32 inches, you can easily play around with your hair with different styles.

All three types of hair length have their pros and cons. Short hair allows you to have a distinct personal style with less maintenance. On the other hand, medium hair gives you more room to experiment and work on your hairstyles. While long hair is a perfect choice if you want to look elegant.

Three Easy Ways on How to Measure Hair Extensions

If you think measuring the perfect hair extension length is complicated, you are wrong. You need to follow only two simple steps to get the desired length and see how they look on you.

Step 1. Get your hair’s length.

When measuring your hair's length, you need to start measuring it from its roots to the tip of your hair. This step applies to all types of hair. Thus, if your hair is curly, wavy, or not of the same length, you need to pull your hair strand to straighten it before measuring its length.

Step 2. Check the hair extension’s length.

Regardless of the form and shape of the hair extension you want to buy, you must measure it like how you measured your hair's length. You should start measuring from the roots to the tip of the hair.

Step 3. Choose the best length.

When choosing the length of the hair extension, you need to make sure that it is longer and not shorter or equal to the length of your natural hair. The ideal hair extension length is 3-4 inches longer than your natural hair.

What are the most common types of hair extension?

Over the years, the beauty industry has evolved into a massive marketplace for beauty enthusiasts. The demand for hair extensions has also grown along with its growth. With various styles, colors, and lengths, hair stylists, hairdressers, and hair extension enthusiasts want to know the best hair extensions and methods that best fit their needs.

Some of the common hair extensions are as follows:

Microbead Hair Extensions

Microbead hair extensions are also known as I-Tip or I-Link. This hair extension is durable and can last up to six months. However, since this hair extension uses tiny beads to help the extension hold to your natural hair, it needs an extra care routine.

Tape-In Hair Extensions

This type of extension is wefts and uses medical-grade tape to attach the extension to your natural hair. This is one of the hair extensions types that is easy to apply and remove, cutting several hours into just 30 minutes.

Since Tape-In Hair Extensions are attached to your hair and not to your scalp, it gives a more natural look, and this type of hair extension also carries a lesser risk of hair damage than other types like glue-in extensions.

Glue-In Hair Extensions

Glue-In hair extensions use latex-based glue that you need to apply into your hair for the hair extension to attach to your hair. This type of hair extension is perfect for those who have good hair volume.  

However, if you use Glue-In Hair Extensions, you must follow the instructions to apply appropriately and remove the latex-based glue and avoid damaging your hair. The Glue-In Hair Extensions may last six to eight weeks with proper care.

How to take good care of your hair extensions?

Each hair extension type has different care instructions in its packaging. But the most basic care regimen for hair extensions is similar to how you should take care of your hair.

  1. Prevent oiliness: Over time, hair extensions can get oily, especially at their roots. You need to prevent this from happening to avoid the hair extension from slipping from your hair.

  2. Don't flip your hair.: To avoid straining the hair attachment, you must not flip your hair often or tie it tightly.

  3. Don't pull your hair: You must be very careful with your hair extensions. Avoid pulling your hair aggressively as it can rip off the hair extension, and it may also strain your natural hair roots.

  4. Wash, dry, and comb your hair extension: Just like your natural hair, you also need to wash your hair extension to take off those dust and dirt. Otherwise, you will have a debris build-up in your hair and scalp.  


Regardless of the hair extension length that you want to buy, you must ensure that it is around 4 inches to 5 inches longer than your natural hair. Also, when choosing the right hair extension color, always go with those that are lighter than your natural hair. This allows your hair extension to blend perfectly with your natural hair.
