Leave it long or cut it short?

We’ve all pondered on this question every time our hair grows an inch longer or every time we style our hair.

Guess what – there’s actually a definitive answer to this because you can find out which hair length suits you best. Try out these four easy hacks that can tell your ideal hair length in just 30 seconds.

The 2.25-Inch Golden Rule

You don’t have to rely on a professional stylist to discover the ideal hair length for your face. The 2.25-Inch Golden Rule, developed by Giles Robinson, the International Training Director of Color Wow and a Senior Stylist at John Frieda Salons UK, offers a simple and effective method.

This golden rule, centred around angles, serves as a fool-proof guide for hairstylists to customise cuts and ensure the length enhances the face shape. All you need is a ruler and a pencil to follow the four easy steps of The 2.25-inch (5.5cm) Rule.

  • Step 1: Prepare a ruler and a pen.
  • Step 2: Position the ruler vertically below your earlobe.
  • Step 3: Place the pen at your chin.
  • Step 4: Finally, compare the distance between your earlobe and the pen.

If the distance between the ruler and the pen is greater than 5.7cm (2.25 inches), you’re more suited for a long hairstyle. However, if the distance is less than 5.7 cm (2.25 inches), short hair is the way to go.

This second method is a little simpler compared to the first as you will not need a pen for it. Here are the steps:

  • Step 1: Measure the width of your forehead, followed by the width of your shoulders.
  • Step 2: Divide the first measurement by the second

If the result is greater than 0.47cm, short hair is likely a better fit for you. But if it is less than 0.47 cm, you should look great with long hair.

Consider Hair Volume

Besides golden ratio, you should also consider your hair volume when you’re deciding whether to keep your hair long or cut it.

If your hair is on the thinner side, having long hair tend to make your face appear larger. In this case, going for short hair can add volume and make your face look smaller and more voluminous.

On the other hand, if you’re blessed with naturally thick, straight hair, spice things up by adding subtle waves or opting for a perm. This not only adds a touch of flair to your locks but also enhances your facial contours, giving them a lifted and stylish appearance.

Consider Jisoo here; although her hair may appear somewhat flat, the added waves at the bottom provide dimension and volume, giving her locks a lively and vibrant appearance.

Height as a Guide

Finally, if you’re still unsure about which hair length suits you, consider your height.

Research suggests that the ideal hair length is around one-third of your height. You can measure and see if it aligns with your proportions.

In fact, shorter hair on petite individuals can make them look lively and cute, emphasising their neck and shoulders, which helps create a more balanced appearance.

Take the 1.57m Soyeon from (G)I-DLE, for instance. While she looks great in both hairstyles, sporting a shorter ‘do help make the petite idol look more proportionate and accentuate her body shape and facial features.

Feel free to experiment with these methods and find the perfect hair length that suits you best. After all, your hair is your canvas, and you have the freedom to choose the style that makes you feel confident and beautiful!
