HD Closure size Comparison of 4x4, 5x5, 6x6, and 7x7

HD Closure Sizes: What’s the Difference Between 4x4, 5x5, 6x6, and 7x7?

Posted by SB Boutique | Hair Education Series

In our last blog post, we broke down the difference between HD lace closures and regular lace closures—and why HD lace is the go-to for that seamless, scalp-melting finish. Now that you know why HD lace is worth it, let’s talk about what HD closure size to get.

At our boutique, we carry HD closure sizes 4x4, 5x5, 6x6, and 7x7. The one you choose depends on how much parting space you want, how you like to style your hair, and how natural you want your install to look. Let’s break it down.

What Exactly Is a Closure?

If you’re new to closures, here’s the quick version:
A closure is a small piece of lace with hair attached. It’s used to "close off" your wig or sew-in while giving your hairline and part a natural look—without needing leave-out. Closures make installs look flawless and protect your natural hair underneath.

All of the closures we sell are HD lace, which means the lace is ultra-thin, soft, and nearly invisible on the scalp. Translation: no ashiness, no thick grids, no clockable installs.

🔍 What Are HD Closure Sizes?

HD closure sizes refer to the dimensions of the lace piece used at the top of your wig or install. The size determines how much coverage and parting space you’ll have.

At SB Boutique, we offer a full range of HD closure sizes:

  • 4x4

  • 5x5

  • 6x6

  • 7x7

Each one has its own benefits depending on your desired look, maintenance level, and install method.

4x4 HD Closure Size

Simple. Sleek. Straight to the point.
The 4x4 is the smallest option, covering a 4-inch by 4-inch square at the crown. It gives you enough lace for a middle part or slight side part with minimal maintenance. It’s perfect for quick installs and clean looks without the extra work.

Best for:

  • Middle parts

  • Quick and easy installs

  • Low-maintenance styles

⚠️ Keep in mind:

  • Limited parting space

  • Not ideal for deep side parts or pull-back styles

HD Closure Sizes like the 4x4 are perfect if you’re keeping it simple, sleek, and protective.

5x5 HD Closure Size

A little more lace, a lot more freedom.
With a 5x5 closure size, you get an extra inch of parting space both ways, which means more styling flexibility and a slightly wider, more natural hairline. It's great if you want your closure to blend better and give a fuller frontal-like effect—without actually installing a frontal.

Best for:

  • More natural-looking parts

  • Slightly deeper side parts

  • Clean, polished installs

A 5x5 hd closure size still keeps things beginner-friendly but offers a more realistic lace layout. You get a touch more freedom without much added effort.

6x6 HD Closure Size

Almost a frontal—without the hassle.
The 6x6 offers even more coverage, giving you more lace to play with. Want to switch up your part? Pull your hair back? Go for a soft swoop? You can do it all with a 6x6. It’s perfect for those who like versatility without the maintenance of a full frontal.

Best for:

  • Deep parts or side parts

  • Low ponytails or updos

  • A more realistic hairline and full coverage

With HD Closure size 6x6, you’re stepping into a more flexible styling zone, while still keeping install and maintenance pretty manageable.

7x7 HD Closure Size

Frontal look. Closure install.
This is the biggest HD closure size we offer, and it gives serious frontal energy. The 7x7 covers more of your head, making it easier to part wherever you want and style it like a frontal—minus the glue, long install time, or regular touch-ups.

Best for:

  • Maximum parting space

  • A full, natural-looking hairline

  • Flexible, creative styling

Think of a 7x7 hd closure size as the best of both worlds: frontal coverage with closure convenience. It's a great option for anyone who wants their install to look ultra-real with less upkeep.

Which One Should You Choose?

Here’s a quick cheat sheet:

HD Closure Size Coverage Styling Options Skill Level
4x4 Basic Low Beginner
5x5 Medium Moderate Beginner
6x6 Wide High Intermediate
7x7 Full Very High Intermediate

Still not sure? Ask yourself:

  • Want something quick and simple? 4x4

  • Need a little more room to part and play? 5x5

  • Like styling variety without doing the most? 6x6

  • Want frontal looks without the frontal maintenance? 7x7
