Quick answer: Frontal labels such as 13×4 and 13×6 are product dimensions, not universal wig-cap sizes. Confirm the unit, which two edges are measured, the usable lace area, the hairline shape, and the exact model’s cap-size options before comparing listings.
What do 13×4 and 13×6 tell you?
They identify two dimensions in a seller’s or manufacturer’s product description, but the listing should explain the measurement path and whether it refers to the full lace panel or its usable parting field. Outre product materials provide model-specific examples: one current listing calls its frontal 13×4, while an older catalog lists a 13×6 frontal on a separate style. These are examples for those products, not a cross-brand sizing standard.
| Record | Why it matters |
|---|---|
| Both stated dimensions and units | “13×4” is ambiguous if the seller does not say which edge is width, which is depth, and whether units are inches. |
| Usable lace area | Reinforced borders, hairline shaping, and construction can reduce the area available for parting. |
| Hairline and ear-tab shape | A nominal width cannot show how the curved edge or side returns fit a particular base. |
| Cap size | Frontal-panel dimensions do not replace circumference and front-to-back cap measurements. |
How should you compare two frontal listings?
Use the same checklist for both: save the exact model page, note the stated lace dimensions, request a diagram if the axes are unclear, and compare the cap-size chart separately. Do not compare a frontal’s lace dimensions with a wig cap’s circumference. If a seller cannot clarify the measurement, record it as unverified instead of assuming two labels are equivalent.
A frontal covers a different area from a crown closure or a perimeter lace construction. Compare closure dimensions and 360 lace terminology separately.
Editorial scope: This is a desk-based comparison of published manufacturer specifications, not a measurement of physical samples. Product lines and dimensions can change.
