When shopping for a lace front wig, you'll frequently encounter two size designations: 13x4 and 13x6. Both are lace front wigs. Both create a natural-looking hairline. But there is one important difference between them — the depth of the lace panel — and that difference has a real impact on how versatile your styling options will be.
This guide explains exactly what those numbers mean, what you can do with each size, and how to decide which is right for you.
What the Numbers Mean
In any lace wig name, the two numbers describe the dimensions of the lace panel in inches:
- The first number (13) is the same for both — the lace runs 13 inches across the hairline, roughly from ear to ear
- The second number is where they differ: 4 inches of lace depth on the 13x4, and 6 inches of depth on the 13x6
Within the lace area, you can part the hair freely to reveal the scalp underneath. Outside of that area, the hair is sewn onto the weft base and cannot be parted.
13x4 Lace Front Wigs
A 13x4 wig gives you 4 inches of lace depth from the hairline toward the crown. This covers the standard parting zone for most everyday styles:
- Center part
- Side part
- Slightly off-center part
For the majority of wearers, 4 inches of lace depth is entirely sufficient. The 13x4 is the most widely available lace front size, comes at a lower price point than a 13x6, and delivers a natural-looking result for all standard styling approaches.

13x6 Lace Front Wigs
A 13x6 wig gives you 6 inches of lace depth — two additional inches compared to the 13x4. Those extra inches open up more styling possibilities:
- Deeper side parts that sit further back on the head
- More convincing scalp illusion across a larger area
- Half-up and pulled-back styles that maintain the natural parting look further from the hairline
- More versatile positioning for different part placements
The 13x6 is a popular choice for wearers who like to switch their parting style frequently or who want maximum styling flexibility from a single wig.

Does the Extra Lace Make a Visible Difference?
For most standard styles — a center or side part, worn down — the difference between a 13x4 and a 13x6 is minimal in day-to-day appearance. Both create a natural-looking hairline at the front.
The difference becomes more apparent when you want to wear the hair in styles that expose the scalp further back from the hairline, or when you want the freedom to adjust your part placement significantly without running into the edge of the lace zone.
Which Should You Choose?
Choose a 13x4 if you:
- Prefer standard center or side parts
- Want the most affordable option
- Are new to lace front wigs
- Don't plan to style the hair in deeply parted or pulled-back looks
Choose a 13x6 if you:
- Like to switch between multiple part placements
- Prefer deeply parted or slicked-back styles
- Want maximum styling versatility from one wig
- Are comfortable with a slightly higher price point for added flexibility
Glueless Options in Both Sizes
Both 13x4 and 13x6 wigs are available in glueless constructions, including wear & go styles with pre-cut lace. If you want the convenience of a no-glue install with the versatility of a 13x6, that combination is available.
