# Why Are There Singular And Even Wig Length?

The length of the wig is measured in inches, 1 inch = 2.54 cm. According to this standard, the length of the 14-inch standard should be 14*2.54=35.56 cm, but why is it marked as 50 cm?

In fact, wigs are divided into singular inches and even-numbered inches. The odd-numbered inches refer to the lengths of 9 inches, 11 inches, 13 inches, 15 inches, and 17 inches. Numbers such as 14-inch, 16-inch, 18-inch, 20-inch, etc. are even-numbered lengths.

Singular-inch hair tails are straight, commonly known as straight hair tails, the thickness of the hair is the same up and down, and the length of the hair is equal to the length of the wig. That is to say, a wig with a length of 13 inches is 35 cm, and the length of the hair from top to bottom is 35 cm.

Even-numbered inches are not straight hair tails, and the thickness of the hair is also inconsistent. For example, a wig with a length of 14 inches, its overall length is 50 cm, but the actual length of the hair is only 33 cm. The upper layer of hair is 33 cm, and the lower layer is 33 cm of hair, so that the two layers of hair are stitched together into a 50 cm wig.

The calculation of the length of even-numbered inches is different from that of odd-numbered inches. For example, for 13-inch and 14-inch wigs, the length of a 13-inch single-digit inch is calculated as 13*2.54, and the length of a 14-inch double-digit inch is calculated as 14*2.54+15. That's right, the calculation method for the length of an even-numbered wig is to add 15 cm to the standard length calculation. Therefore, the even-numbered wig will always be 15 cm longer than the odd-numbered wig of similar size. This 15 cm is the effect of splicing and extending.

The advantage of the even-numbered wig is that the length can be 15 cm longer than the odd-numbered wig at the same price, which is more cost-effective. The disadvantage is also obvious, that is, the hair tail is relatively sparse, but also more natural, close to naturally growing hair.
