A 4x4 closure is a 4-inch by 4-inch piece of lace with hair knotted into it. A 5x5 is 5 inches by 5 inches. That one extra inch gives you more room to part, more lace to blend at the edges and a bit more to cut and customize. Choose the 4x4 if you want a simple, easy-to-maintain look with one dependable part. Choose the 5x5 if you want to move your part around and want the most natural-looking scalp area.
Below is how the two sizes compare in practice, who each one suits, where 6x6 fits in, and what to check before you order.
TL;DR
- 4x4: smaller, quicker to install, easier to maintain, and best for a consistent style with a middle or slightly off-center part.
- 5x5: one extra inch of lace in each direction, so more parting freedom and a more blended look at the crown and sides.
- Budget: the smaller closure usually costs less. The gap is small compared with what a poor fit or the wrong texture costs you.
- Not a frontal: a closure covers the top of the part area only. It does not run ear to ear.
- Hair quality matters as much as size. Raw, cuticle-aligned hair lasts through repeated installs, whichever size you pick.

What the measurements mean
Closure sizes are given as width by depth in inches, and each size gives you a different amount of coverage and parting space, as a stylist-run hair journal explains. So a 4x4 is about four inches across and four inches front to back. A 5x5 is about five by five. A 6x6 is about six by six.
The lace is a square. Hair is hand-knotted into it, and you sew or glue it to the top of your install, then leave out little or none of your own hair around it. The knots at the front of the square become your “scalp” and your part.
Two practical notes:
- Sizes are approximate. Lace is trimmed by hand, so measure the piece when it arrives.
- Bigger does not mean denser. A larger closure spreads the same kind of knotting across more area, so fullness is a question of hair quality and how the closure is made.
Closure or frontal?
People often ask whether a 5x5 is a closure or a frontal. It is a closure. A closure sits in one section at the top, and a frontal is a wide strip that runs from ear to ear and lets you pull hair off the face in any direction. If you want to wear your hair swept back or in a high ponytail with a full hairline, you want a frontal. If you want a clean part and a lower-maintenance install, a closure does the job. We break that decision down in closure vs frontal.
4x4 vs 5x5 side by side
| 4x4 closure | 5x5 closure | |
|---|---|---|
| Lace size | About 4 in × 4 in | About 5 in × 5 in |
| Parting space | Middle or slight side part in a fixed zone | Middle, side and deeper side parts |
| Natural look | Very natural when the part stays where it is | More blending room, so edges and crown disappear more easily |
| Install | Faster, simpler to cut and fit | More lace to trim and bleach knots on, so it takes more care |
| Styling freedom | Good for everyday styles | Better if you change your part |
| Price | Usually lower | Usually higher |
| Best for | First-timers, budget installs, simple styles | Parting freedom, bigger heads or fuller leave-out, a polished finish |
Coverage and parting space
The 4x4 gives you a defined window. You can part it in the middle, or push it a little to one side. When you move the part much further, you start to see the edge of the lace or the wefts behind it.
The 5x5 gives you an extra inch of room. That is enough for a deeper side part, and it lets you shift the part from one day to the next without exposing the edge of the lace. The extra lace also sits further back on the head, which makes the transition into your hair or the surrounding bundles easier to hide.
A simple way to decide is to think about how you actually part your hair on a normal morning. If it is the same place every day, the 4x4 is plenty. If you change it up, buy the 5x5.
Is a 4x4 closure good?
Yes, for the right job. A 4x4 is the most common closure size, and it gives a natural-looking part when you install it properly. The Press Room Salon article notes that a 4x4 suits simple, consistent styles, and that matches what we see.
The practical limits are:
- A narrower parting zone. Push the part too far and the lace edge shows.
- Less lace to blend. On a fuller leave-out, or a head where the closure lands in a tricky spot, the edge needs more careful work.
- Less forgiving of slight misplacement. If it is sewn on a little off, there is less spare lace to hide it.
None of these is a flaw. They are the cost of a smaller, simpler piece, and for many people they are a fair trade for a faster, cleaner install.
Is a 5x5 closure worth it?
For many people, yes. A 5x5 gives you more of what a closure is for: a believable scalp and a part you can move. It also tends to look better on a larger part area, because the lace edge sits further from where your eye lands.
The trade-offs are real, though:
- More lace to prepare. You will trim, pluck and tint more of it, and that takes time or a stylist’s hours.
- More to match. A bigger lace square means more area where the lace color has to match your skin. Our guide to color matching extensions covers that.
- A slightly higher price. Larger pieces typically cost more.
The Press Room Salon article also points out that larger closures may require more customization, so skill level counts. A confident DIY installer can handle a 5x5. A first-timer working alone may do better starting with a 4x4.
How 5x5 compares with 6x6
A 6x6 is the next step up: about an inch more in each direction again. It gives the deepest parting space of the three and is the closest a closure comes to the freedom of a frontal. It also takes the most trimming and the most care to blend, and it can reach beyond where some installs need it.
For most people, the decision looks like this:
- Pick 5x5 if you want freedom to move your part and a generous but manageable amount of lace.
- Pick 6x6 if you want the maximum parting range from a closure, and your install has the room for it.
- Pick 4x4 if neither of those matters to you.
We go through the details in 5x5 vs 6x6 closure.
Which one fits your situation
If you are new to closures
Start with a 4x4. It is quicker to fit, cheaper to learn on, and it forgives less than you might fear because you only need one good part.
If you part your hair in different places
Go with the 5x5. You get a deeper side part and room to change your mind.
If you are on a tight budget
The 4x4 usually costs less, but check the hair first. A cheaper closure made from processed hair can tangle, lose its texture and need replacing sooner than a better one that costs a little more.
If you are a stylist
Keep both sizes on hand. A 4x4 handles quick sew-ins and clients who want one fixed part. A 5x5 handles clients who want flexibility and a polished, blended finish. Matching the size to the client’s head and their usual part saves you rework.
If you want to bleach or color it
Both sizes can be colored, but a larger closure means more lace to bleach and tone. Take your time with the knots. Our #613 blonde 4x4 straight closure and #613 blonde body wave 5x5 closure come in the lightest shade, which gives you the best base for toning.
What to check before you buy
Size is only part of the decision. These are the details that decide whether a closure still looks good after several installs.
- Hair type and processing. Raw, unprocessed hair keeps its cuticles aligned in one direction. That helps it resist tangling and hold its texture over time. Hair that has been stripped or steam-processed can look fine on day one and change fast.
- Knotting and density. Look at the hairline of the closure. You want it to look soft and slightly sparse at the front and fuller further back.
- Lace feel. The lace should feel fine but not flimsy. It should lie flat against the scalp.
- Texture. Pick the pattern that matches your bundles. If you are torn between waves, read body wave vs deep wave or body wave vs loose wave.
- Matching the bundles. Closure and bundles should come from the same type of hair so the color, shine and curl pattern line up. If you are unsure how many bundles you need, the Press Room Salon explains it for a sew-in with a closure.
- Return and exchange terms. Check them before you cut or color anything, because they usually change once the lace has been altered.
Our perspective
We sell raw, unprocessed hair, and we see a pattern. People often fixate on 4x4 versus 5x5 when the thing that decides how the install looks in month two is the hair itself. A well-made closure in either size looks natural. A poor one looks off in either size.
So our advice is simple. Choose the size by how you part your hair and how much work you want to do at install. Then spend your attention on the quality of the hair. Cuticle-aligned hair with no chemical or steam processing keeps its texture and luster through multiple installs, which is the reason we focus on it. It also takes coloring and bleaching well, so you can adjust the shade to your skin.
If you are undecided, we lean toward the 5x5 for anyone who changes their part and the 4x4 for everyone else. You are not locked in. Many of our customers and stylists buy one of each over time.

FAQ
Which closure size is best?
There is no single best size. A 4x4 is best for simple, consistent styles and easier installs, a 5x5 for more parting freedom and a more blended look, and a 6x6 for the widest parting range. Match the size to how you part your hair and how confident you are at installing.
Is a 4x4 closure good?
Yes. It gives a natural part, installs quickly and usually costs less than larger sizes. Its limit is a narrower parting zone, so it works best when you keep your part in about the same place.
What does 4x4 closure wig mean?
It means the wig has a 4-inch by 4-inch lace area at the top where hair is knotted in, which gives you a part. The rest of the cap is usually wefted hair. A 4x4 closure wig is not the same as a frontal wig, which has a lace strip across the whole hairline.
Is a 5x5 a closure or frontal?
It is a closure. It is a square piece of lace, larger than a 4x4, that covers the part area. A frontal is a long, narrow strip that runs ear to ear and lets you style the hairline in more directions.
Can I cut a 5x5 down to a 4x4?
You can trim lace, but you will lose knotted hair and the natural blending that comes with the larger size. If you only need a 4x4, it is better to buy one than to cut a 5x5 down.
