Cracking the Lace Code: 4x4, 5x5, 13x4, and 13x6 Explained

You have finally picked out the perfect Brazilian Hair bundles for your next install. You head over to the lace section to complete your cart, and suddenly you are hit with a bunch of numbers: 4x4, 5x5, 13x4, 13x6.

If you find yourself staring at your screen wondering, "What do these numbers actually mean, and which one do I need?" you are not alone! These numbers simply refer to the measurements (in inches) of the lace material, which dictates how much parting space you will have once the hair is installed.

Understanding these sizes is the key to achieving your dream hairstyle. Let’s crack the lace code so you can shop with confidence at Her Hair Company.

1. The Closures: 4x4 vs. 5x5

A Lace Closure is a square or rectangular piece of lace that sits at the top center of your head. It is perfect for low-maintenance, everyday, glueless installs.

• 4x4 Lace Closure (The Standard): This lace piece is 4 inches wide (across your forehead) and 4 inches deep (going back toward your crown).

  • Best For: The classic middle part or a very slight, narrow side part. It is the most beginner-friendly and budget-friendly option.

• 5x5 Lace Closure (The "Mini Frontal"): This piece gives you an extra inch of width and depth (5 inches across, 5 inches back).

  • Best For: Those who want the low maintenance of a closure but crave more styling versatility. That extra inch allows for a much deeper, more dramatic side part without having to shift the closure from the center of your head.

2. The Frontals: 13x4 vs. 13x6

A Lace Frontal stretches across your entire hairline from ear to ear (which is the "13" measurement). Frontals offer the ultimate styling freedom, allowing you to pull your hair back.

• 13x4 Lace Frontal (The Industry Standard): This frontal spans 13 inches horizontally across your hairline and goes 4 inches deep into your crown.

  • Best For: Most versatile styles, including middle parts, side parts, and half-up/half-down styles. It provides a flawless, natural-looking hairline across your entire forehead.

• 13x6 Lace Frontal (The Ultimate Versatility): This is the luxury upgrade. It spans the same 13 inches from ear to ear but goes a massive 6 inches deep into your crown.

  • Best For: Maximum parting space. If you love extremely deep, swooping side parts, intricate braided styles at the front, or just want the most realistic scalp illusion possible, the 13x6 is your holy grail.

3. Don't Forget the HD Upgrade!

Regardless of which size you choose, the quality of the lace is what truly makes or breaks the install. At Her Hair Company, we highly recommend selecting our premium HD Lace options. HD lace is incredibly thin and sheer, melting seamlessly into every single skin tone for a truly undetectable, "grown from the scalp" look.

The Final Verdict

• Want a simple middle part that you don't have to glue down? Get a 4x4 or 5x5 Closure.

• Want to recreate Pinterest-worthy half-up styles and deep side parts? Invest in a 13x4 or 13x6 Frontal.
