2×6 vs 4×5 vs 5×5 Lace Closures: Which Size Should You Choose?
Choosing a lace closure starts with one question: how much space do you want for your part? The numbers describe the lace area in inches. A 2×6, 4×5, and 5×5 closure can all finish a sew-in or custom wig, but they give you different amounts of lace to work with.
Quick comparison: 2×6 vs 4×5 vs 5×5
| Closure size | Best for | Parting flexibility | Lace to manage |
|---|---|---|---|
| 2×6 | A long, defined part with a narrow lace area | Limited side-to-side movement | Least of these three |
| 4×5 | A balance of coverage and flexible parting | More room than 2×6 | Moderate |
| 5×5 | More room to change the part and style the top | Most of these three | Most of these three |
The measurements refer to the closure's lace area, not the hair length. A larger lace area can offer more styling room, but the finished look also depends on placement, customization, and installation.
When should you choose a 2×6 closure?
A 2×6 closure is long and narrow. It works well when you know where you want your part and prefer less lace to install and maintain. It can create a defined part for a straight, body wave, or deep wave sew-in. Because the lace is narrow, it gives you less freedom to move the part far to either side.

When should you choose a 4×5 closure?
A 4×5 closure gives you a wider lace area than a 2×6 while keeping the installation relatively compact. It is a practical middle option if you want some room to adjust your part but do not need the largest closure in this comparison.

When should you choose a 5×5 closure?
A 5×5 closure provides the widest lace area of these three choices. It offers more room to place or change your part and style around the top of the install. It also means more lace to place and customize than a smaller closure. If flexibility matters more to you than minimizing the lace area, start here.

How do you decide for a sew-in?
- Pick your intended part. For one consistent, defined part, consider 2×6. If you may change the placement, compare 4×5 and 5×5.
- Think about installation. More lace gives your stylist more area to work with, but it also requires careful placement and blending. Ask your stylist which size fits the braid pattern and look you want.
- Match the hair. KIWI offers these three HD lace closure sizes in Straight, Body Wave, and Deep Wave, with lengths from 10 to 18 inches. Choose a texture and color that work with your bundles.
Frequently asked questions
Is a 5×5 closure always better than a 2×6?
No. The best size depends on your style. Choose 2×6 for a narrow, defined part and less lace; choose 5×5 when greater parting flexibility is the priority. The 4×5 sits between them.
Can you make a side part with a 2×6 closure?
Part placement depends on how the closure is installed, but the narrow lace area limits how far you can shift the part afterward. If you want more freedom to change it, a 4×5 or 5×5 may be easier to work with.
Is a closure the same as a frontal?
No. A closure covers a smaller area at the top of the install; a frontal spans more of the front hairline. For that separate decision, read our lace frontal vs closure guide.
Which closure should you choose?
Choose 2×6 for a long, narrow part; 4×5 for a middle ground; or 5×5 for the most parting room among these three. If you are planning a sew-in with a stylist, share your desired part and bundle texture before ordering so the closure fits the install.
