13x6 Lace Front Wigs: What the Extra Two Inches Actually Give You
Most people arrive at the lace size question with a rule of thumb someone told them, and then discover the rule does not apply to them. The rule is usually "bigger is better", and it is wrong more often than it is right. A 13x6 lace front gives you two extra inches of lace depth compared to a 13x4. Whether those two inches are worth anything to you depends almost entirely on which hairstyles you actually wear, and that is a much narrower question than it sounds.
Here is the thing about lace sizes that gets buried in the marketing: the two numbers mean two different dimensions, and the second one is the one that changes your options. The first number is the width across the front of the head, measured in inches from ear to ear. The second number is the depth, measured from the hairline toward the crown. A 13x4 is thirteen inches wide and four inches deep. A 13x6 is the same thirteen inches wide and six inches deep. Width controls how much of your hairline you can cover. Depth controls how much hair you can pull back over the lace before the edge shows.
That second part is why depth is the number worth arguing about. Width barely matters to most people because nobody can see the width of your lace when your hair is down. Depth is entirely visible when you tie your hair up, and it is the difference between a hairline that disappears and a hairline you can see from across a room.
What the extra two inches actually do
Think about what happens physically when you pull hair straight back into a ponytail. The hair has to travel upward and backward over the top of your head, and the lace underneath has to disappear under that hair. With four inches of depth, you have four inches of lace to blend, and the hair has to be pulled back far enough to cover the full four inches. With six inches, you have two more inches of room, which means the hair can sit further back from your forehead and still look natural at the front.
This is why a 13x6 shows up in the "high ponytail" category and a 13x4 does not. It is not that the 13x4 looks bad in a high ponytail. It is that you will be visible, and you will be visible within about a second of the other person seeing it. The lace edge will catch the light differently from the surrounding skin, and it will form a line across the temples that no amount of styling product fully hides.
| Lace size | Width | Depth | Best for |
|---|---|---|---|
| 4x4 closure | 4 in | 4 in | Centre part, budget |
| 5x5 closure | 5 in | 5 in | Centre part, more natural parting |
| 13x4 frontal | 13 in | 4 in | Down styles, side parts |
| 13x6 frontal | 13 in | 6 in | High ponytails, slick backs |
| Full lace | Full | Full | Any parting, updo freedom |
Which styles genuinely need the 13x6
There are three, and they are worth being specific about because the list is short.
A high ponytail is the clearest case. The hair goes straight back off your face and the entire front edge is under tension and fully visible from the side. This is where a 13x4 gives itself away and a 13x6 disappears. If you wear a high ponytail to work, to the gym, or anywhere with a mirror in the building, you already know which category you are in.
A slicked-back style is the second. Whether it is a low bun or a flat ponytail combed straight back with gel, the same logic applies, just with less severity. A 13x4 can get away with it on a good hair day. A 13x6 does it on any hair day.
A deep side part is the third, and it is the one people underestimate. When you part deeply and sweep the front section across, you expose the opposite side of the parting, and the depth of the lace determines whether there is enough lace left to blend that exposed area. Four inches can look thin there. Six inches has material to spare.
Everything else does not need it. A centre part with the hair down is the case most people are actually in, and a 13x4 and a 13x6 are indistinguishable in that situation. If your everyday is centre part, down, then you are paying for something you will not use.
What it costs, and whether that is worth it
On our units, going from a 13x4 to a 13x6 typically adds 40 to 100 US dollars depending on length and density. That is more than a rounding error, so it deserves a real answer rather than "go bigger".
The cost is a combination of materials and labour. The extra two inches of lace area has to be hand-tied, and hand-tying is the slowest part of making a wig. But the price difference is not really about the hair, because you can get the same grade of hair at either size. It is about what the extra construction buys you in styling freedom.
Here is how we would frame it for someone who has never worn a wig. If you have never worn a wig, buy a 13x4 and learn on it. You will learn how to install a lace front, how to handle the adhesive, how to sleep with it and how to wash it, and none of that changes if you upgrade later. If you have worn wigs for years and you already know that you wear your hair up, then a 13x6 is the correct first purchase rather than a step up from a 13x4.
The install difficulty is real, but small
We are not going to pretend a 13x6 installs exactly like a 13x4, because it does not. The extra lace area means more of the lace has to be adhered, and if you pull the hair straight back, the entire visible edge has to disappear rather than just the front of it. On a 13x4 we spend about 20 to 25 minutes on a full install. On a 13x6 it is closer to 25 to 30. That difference is real but it is not the kind of difference that should decide the purchase.
The larger lace area is also slightly more forgiving on a first attempt, because you have more room to position the wig before the adhesive sets. Beginners sometimes find the 13x6 easier to get right, which is counter-intuitive but comes up often enough to be worth mentioning.
A note on how the depth affects your hairline
More depth does not mean more hair on your forehead, and this is worth clearing up because it is a common misunderstanding. Depth is how far the lace extends back toward your crown, not how far forward it comes onto your forehead. Your hairline position is set by how the wig is constructed and by the plucking work that goes into it, and the finish varies by product. Check the individual listing for details such as pre-plucking and knot treatment.
What the extra depth does change is the balance of the hairline. On a 13x4, most of the visual weight of the hairline is concentrated in a narrow band at the front. On a 13x6, that density spreads further back, so the transition from hairline to hair is less abrupt. It is one of those differences that a photographer would notice before a customer does.
The short version
If you wear a high ponytail, a slick back or a deep side part, go to the 13x6. If you wear a centre part with your hair down most of the time, a 13x4 will look the same and cost less. If you are buying your first wig, start with a 13x4 and learn on it. And if you need a genuinely closed centre part without any lace at all, that is a different construction and a different question.
Frequently asked questions
What is the difference between a 13x4 and a 13x6 lace front?
Both are 13 inches across the front, but the second number is how deep the lace runs from the hairline toward the top of your head. A 13x4 gives you four inches of depth, a 13x6 gives you six. The extra two inches matter when you pull the hair back or into a high ponytail, because there is more lace area to blend into your own hair. If you wear your hair down with a normal parting most of the time, the difference is not visible.
Is a 13x6 lace front worth the extra money?
It is worth it if you wear ponytails, buns, or deep side parts regularly, and it is wasted money if you do not. The depth only pays off when there is hair to pull back over it. On our units the upgrade is usually 40 to 100 US dollars depending on length and density, so if you know you will be tying your hair up, take the 13x6. If you are undecided and mostly wear it down, a 13x4 looks identical and costs less.
Does a 13x6 lace front look different from a 13x4 when worn down?
No. With the hair down and parted normally, the lace area is covered by your own hair on either side, and the two are indistinguishable. You can tell them apart only when the hair is slicked back, which is exactly why the 13x6 exists. If you are buying a 13x6 you should be planning at least some styles that need the extra depth, otherwise you are paying for construction you will not use.
Is a 13x6 harder to install than a 13x4?
Slightly, and the reason is the depth rather than the width. On a 13x4 you only need to lay down the front edge and the sides stay within the natural hairline. On a 13x6 the lace reaches further back, so more of it has to be adhered, and if you pull the hair straight back the whole visible edge has to disappear. It takes us about five minutes longer per install. For someone wearing it every day that is not a deciding factor, but it is worth knowing before you commit.
Can I wear a 13x6 lace front with a high ponytail?
Yes, and that is the single clearest reason to choose it over a 13x4. With six inches of depth across the forehead and temples, you can brush the hair straight back and secure it without the lace edge showing. On a 13x4 the sides give out sooner, so a high ponytail usually exposes a line. If you wear a high ponytail to work or the gym even once a week, the 13x6 is the correct buy.
