In a 13x4 vs 13x6 comparison, the numbers are inches of lace: the first is how far the lace runs across the head, and the second is how deep it goes front to back. A 13x4 is thirteen inches wide and four inches deep. Those dimensions describe lace coverage and possible parting space; they do not by themselves determine every hairstyle, fit or price.
Nobody explains it that way, which is why the terminology feels harder than it is. Once you know what you're buying by the inch, the choice takes about a minute.
A closure uses a more local lace area around the part, while a frontal covers a wider section across the front hairline. A 13x4 and a 13x6 are both frontals with the same nominal width; the second number changes their depth. Choose between them according to the parting space you need and the actual cap construction shown by the seller, not the size label alone.
What the Numbers Actually Measure
Every lace size follows the same convention: width × depth, in inches. Width runs side to side across the front of your head. Depth runs back from your hairline toward your crown.
| Size | Lace area | Where it sits | Called a |
|---|---|---|---|
| 4x4 | 4in wide × 4in deep | A square patch over the top of the head | Closure |
| 5x5 | 5in wide × 5in deep | Same position, more room around the part | Closure |
| 13x4 | 13in wide × 4in deep | Ear to ear across the front hairline | Frontal |
| 13x6 | 13in wide × 6in deep | Ear to ear, extending further back | Frontal |
That's the entire naming system. A 13x6 isn't a different kind of wig from a 13x4 — it's the same thing with two more inches of lace behind the hairline.
The dividing line between "closure" and "frontal" is width, not quality. Anything roughly 4–7 inches wide sits over the top of your head and is a closure. Anything around 13 inches spans the full front hairline, ear to ear, and is a frontal. Both can be HD lace, transparent lace or regular lace — that's a separate question about the lace material itself, not its size.
13x4 vs 13x6: Parting Space and Styling Limits
Lace area can affect the parting space a product is designed to offer. Whether a particular wig can be pulled back also depends on its lace layout, cap construction and the seller’s demonstrated styling guidance.
| Size | Parting | Can you pull it back? | Suits |
|---|---|---|---|
| 4x4 closure | Check the seller’s demonstrated parting area within the closure | Confirm the cap layout before planning a pulled-back style | A fixed or limited parting routine |
| 5x5 closure | More nominal area than 4x4; confirm the product’s usable parting space | Confirm the cap layout before planning a pulled-back style | A buyer wanting a closure with more room around the part |
| 13x4 frontal | Wider front coverage; check the product’s demonstrated parting depth | Confirm the full cap and nape construction with the seller | A buyer wanting frontal coverage without assuming every updo is supported |
| 13x6 frontal | More nominal depth than 13x4; check the product’s demonstrated parting depth | Confirm the full cap and nape construction with the seller | A buyer who expects to use the additional depth |
Keswigs, for example, describes one of its comparison ranges as roughly "1.5-2 inches from center" for a 13x4 side part and "deep side parts (up to 4 inches from center)" for a 13x6. Treat those as that seller’s product guidance, not a universal linear conversion between lace depth and side-part distance. Check the product you are considering.
Choose the depth that matches the parting space you expect to use, after checking the product’s demonstrated styling and full cap layout.
What You're Actually Paying For
Price reflects more than lace size. Hair material, length, density, cap construction, processing, retailer pricing and promotions can all differ between listings. Compare like-for-like specifications before treating a lace-size difference as the reason for a price difference.
Keswigs lists one published comparison range of "$150-250" for 13x4 lace front wigs and "$200-350" for 13x6. Those are that source’s stated ranges, accessed 2026-09-20, not an industry-wide price rule.
When comparing two otherwise similar listings, ask what each seller specifies about the construction rather than using price as a quality verdict:
- Lace area. The listed lace coverage is one specification to compare with the parting space you want.
- Construction details. Check how the seller describes the lace, knots, cap and hair material for that product.
- Wear and care requirements. Review the seller’s fitting, styling and care guidance before choosing a higher-priced option.
A price difference alone does not establish quality. If two listings appear similar, compare their full specifications, seller policies and product demonstrations before deciding which trade-off matters to you.
Which One to Buy
| If this is you… | Buy | Why |
|---|---|---|
| First wig, wearing it down | Compare 4x4 or 5x5 closure options | Check the seller’s lace-cutting, blending and care instructions before choosing |
| You want a natural front hairline | Compare frontal options | Check the product’s demonstrated front coverage and fitting instructions |
| You restyle often — changing your part or pulling hair back | Compare 13x4 and 13x6 frontals | Confirm usable parting space, lace layout, cap and nape construction before assuming an updo is supported |
| Short or bob styles | Compare closure and frontal options | Choose the coverage and parting space you expect to use rather than treating extra depth as automatically wasted |
| You expect more active wear | Compare closure and frontal options | Review the seller’s cap, nape, attachment and care guidance for the exact product |
A larger lace dimension is not automatically a better choice. Compare the listed coverage, usable parting guidance, cap layout and your planned styling routine before paying for additional depth.
Where Glueless Changes the Calculation
Some glueless designs use cap features rather than adhesive, but the fastening system and lace preparation vary by product. Read the seller’s instructions rather than assuming a particular lace size determines how the wig is secured.
If a listing describes a wig as glueless, check whether its lace is pre-cut, what fitting steps it requires and how the cap is meant to be secured. Our lace front application guide covers a traditional application method if you want to compare the processes.
Lace size and cap measurements are different dimensions of the purchase. For the cap-fit side of that decision, see our wig cap sizes and types guide.
FAQ
What does 13x4 mean on a wig?
Thirteen inches of lace across the front hairline, ear to ear, and four inches deep from the hairline back toward the crown. Width first, depth second.
What is the difference between a closure and a frontal?
Width. A closure is roughly 4–7 inches across and sits over the top of your head. A frontal is around 13 inches and spans the entire front hairline.
Is 13x6 better than 13x4?
Neither is automatically better. A 13x6 has more nominal depth, but you should choose only after comparing the seller’s usable parting guidance, cap layout and your planned styling routine.
Can you make a ponytail with a 13x4?
Do not infer this from the 13x4 label alone. Check the seller’s demonstration, cap and nape layout, attachment method and styling instructions for the exact wig.
How should I choose between a closure and a frontal?
Start with the coverage and parting space you expect to use, then compare the specific product’s lace layout, fitting steps, care guidance and return terms.
