Short hair extensions

For your hair extensions to be classified as short in the hair extensions length chart, the length must be 10 inches and 12 inches. It will run right above your ear down to your chin. 

Moderately long hair

This hair length is most popular on the hair extensions length chart, as you can easily style and dye it. Medium-length hair, most commonly known as shoulder-length hair or over-shoulder hair, is about 14 inches to 22 inches long, which can make you look both classic and trendy.

Long hair

Long hair at the same time represents beauty, femininity, class, elegance, and fashion. With a hair length of at least 24 inches to 32 inches, you can easily transform your hair with many different styles.

All three types of hair lengths have their pros and cons. Short hair allows you to have a distinct personal style with less care. Medium hair, on the other hand, gives you more space to experiment and work with many hairstyles. While long hair is a perfect choice if you want to look elegant.

How to measure the length of hair extensions?

Method 1: If your hair extensions are disassembled

You just need to prepare a measuring tape and measure from the hairline to the weft and you will have the measurement of that hair extension.

Curly and wavy styles are measured the same, but when measuring, the hair must be straightened to get an accurate measurement.

Method 2: If you are wearing hair extensions

Step 1: Stand in front of the mirror with a measuring tape

Step 2: Hold the measuring tape at the position you have attached your extension to your real hair then let the measuring tape fall down.

The spot where the measuring tape falls and touches the end of the hair extension is the length of the extension (for curls, subtract 2 inches from straight extensions).

How to choose the correct length of hair extensions?

If you’re looking to change up your hairstyle with hair extensions but keep asking yourself the question “How to choose the correct length of hair extensions?”, here are a few tips we’ve put together to help you find the right answer and perfect hairstyle.

Consider your height

Hair of the same length will look completely different in a person depending on their height. For example, for a short woman, the 18-inch hair extension will come close to the waist while for a taller girl it will be just slightly below the shoulders.

Therefore, if you’re shorter than average, you’ll probably fit 12 to 16 inches extensions. If you are of average height, 20 to 24 inches is ideal. If you’re taller than average, consider 24 to 30 inches.

How you’ll style the extensions

How you want to style your extensions will also affect the length you should choose. If you intend to keep the extensions straight and only trim the small part, the length of hair extensions won’t change much. However, if you want to layer or curl your extensions, choose bundles that are two inches to three inches longer than originally intended.


Remember that wavy and curly extensions are measured straight. Therefore, if you want a specific length of hair, get a bundle that is 2 inches (5 cm) longer than the target length for wavy hair and 4 inches (10 cm) longer for very curly hair

Your habits

If you always keep your hair short to medium length, then you may have a hard time using long or very long hair extensions as it will take more effort to take care of. If so, you can consider a length of about 3 inches longer than your current hair will be much more suitable

Choosing length for increasing volume

Many people use hair extensions to increase the thickness of thinning hair rather than to increase length. In this case, it’s best to choose extensions that are only two inches longer than your natural hair. In addition, add only a few wefts or use a low volume of extensions adding too much volume of hair exertions will look unnatural.

Final thoughts

While the hair extensions length chart will help you choose the right extension length, there is one last thing you need to keep in mind: whichever length you choose, it should be in perfect harmony with your hair. To ensure this, you may have to experiment several times to find the length that works best for you.
