Understanding Hair Lengths


When picturing hair length, it’s useful to have a general idea. You need to know what different measurements mean. Here’s a quick rundown:

  • Chin-Length: Typically around 8-10 inches, this length is common for classic bob cuts.
  • Shoulder-Length: Hair usually measures 12-14 inches. It is easy to manage and style.
  • Mid-Back Length: Falling between 18-22 inches, this length offers more styling flexibility while still maintaining considerable length.
  • Waist-Length: At approximately 26-30 inches, this is considered long hair and opens up a wide range of styling possibilities.

Measuring Hair with Measuring Tape

In a tutorial by Newtimes Hair, they emphasize the importance of accurate hair measurement techniques. They recommend measuring the length of the hair from the root at the scalp all the way down to the tip of the hair strand. A soft tape measure is the most accurate tool for measuring hair. Here’s how to use it:

  1. Straighten Your Hair: Make sure your hair is as straight as possible for an accurate measurement. If you have curly or wavy hair, consider using a flat iron to straighten it.
  2. Position the Tape: Place the end of the tape measure at the root of your hair on your scalp.
  3. Measure to the Tip: Extend the tape measure along the length of your hair to the very tip, keeping it taut without pulling your hair.
  4. Read the Measurement: Take note of the length where your hair ends on the tape measure.

Alternative Ways to Measure Hair

If you don’t have a tape measure, you can use other methods to measure your hair:

  • Using a Ruler: If your hair is short, you can use a ruler to measure its length. Just align the end of the ruler with the root of your hair and measure to the tip.
  • Using a String: For longer hair, you can use a piece of string. Place one end of the string at the root of your hair and extend it to the tip. Mark the point where your hair ends on the string, then measure the string with a ruler for an accurate length.
  • Using Scotch Tape: If you’re in a pinch, Scotch tape can be a makeshift measuring tool. Stick a piece of tape at the root of your hair and extend it to the tip. Mark the end of your hair on the tape, then measure the tape with a ruler. While not as precise as a tape measure, it can give you a rough estimate of your hair length.

Common Mistakes to Avoid

When measuring your hair, it’s easy to fall into a few common traps. Here are some mistakes to avoid for accurate results:

  • Not Straightening Curly or Wavy Hair: To get the true length, ensure your hair is straightened if it’s naturally curly or wavy.
  • Measuring from the Wrong Point: Always measure from the scalp at the root of your hair, not from the hairline or the end of your hair.
  • Pulling Hair Too Taut: While you want the tape measure to be tight, pulling your hair too much can lead to an overestimation of its length.

How Often Should I Measure My Hair?

For those tracking growth, measuring your hair every 4-6 weeks is a good interval. This frequency allows you to see progress. It does so without fixating too much on daily or weekly changes. Those changes can be discouraging if they’re not immediately noticeable.

How Do I Measure Hair for Layers or Different Hairstyles?

For layered hair, measure the longest and shortest layers separately. This gives an accurate view of your hair’s total length. For specific hairstyles, measure based on where the style falls (e.g., chin-length for a bob). This will give you a clearer idea of how much length you need to achieve the desired look.

What’s the Best Way to Measure Hair for Extensions?

When it comes to measuring for hair extensions, getting the right length is crucial for a natural and seamless look. Here’s how to measure your hair for extensions:

  • Determine the Starting Point: Decide where you’ll be attaching the extensions. For clip-ins, this is usually near the nape of your neck.
  • Measure the Length: Using a tape measure, measure from the attachment point down to where you want the extensions to end. This will give you the length of extensions you need.
  • Measure the Width: For a full head of extensions, you’ll also need to measure the width of your hair. Take horizontal measurements across your head where the extensions will be placed to ensure they fit well and provide even coverage.

Can I Measure My Hair When It’s Wet?

Measuring your hair when it’s wet can give you a different length compared to when it’s dry, especially if your hair has a lot of shrinkage when it dries. For the most accurate measurement:

  • Measure When Dry: If possible, measure your hair when it’s dry and styled as you usually wear it. This will give you a more accurate representation of its length in its natural state.
  • If Measuring Wet: If you must measure your hair when it’s wet, be aware that it may appear longer due to the weight of the water pulling it down. Once your hair dries, it may shrink back to its usual length.

Tips for Maintaining Healthy Hair Length

Maintaining your hair’s length and health requires regular care. Here are some tips:

  • Trim Regularly: Regular trims, every 8-12 weeks, can prevent split ends from traveling up the hair shaft and causing breakage.
  • Use Protective Hairstyles: Styles like braids or buns can protect your ends from damage and help retain length.
  • Invest in Quality Hair Care Products: Use shampoos, conditioners, and treatments that are suited to your hair type and needs.
  • Minimize Heat Styling: Excessive use of heat styling tools can lead to damage and breakage. Use heat protectants and limit heat styling when possible.

Measuring your hair is simple but crucial. It’s part of your hair care routine. You do it whether you’re tracking growth, planning a haircut, or fitting extensions. With the right tools and techniques, you can measure your hair accurately. You can also make informed decisions about it. Remember, precision is key for hair measurement.
