The width of naturally formed double eyelids is generally between 5-8mm, and those below 5mm are relatively narrow and those above 8mm are relatively wide. How wide the double eyelids should be cut can't be generalized. Different beauty seekers are suitable for double eyelids with different widths. Experienced plastic surgeons will tailor the suitable double eyelids according to the physical condition, temperament characteristics and professional characteristics of the beauty seeker.

Many beauty seekers blindly seek to cut their eyelids wider, hoping to have double eyelids like westerners. The doctor pointed out that this idea was unreasonable. The proportion of facial features between orientals and westerners is very different. Westerners' facial features are three-dimensional, while Europeans' double eyelids are relatively wide, which can be in harmony with the three-dimensional facial features, so they look good. However, the profile of oriental facial features is relatively weak, and the width of European double eyelids is too large, which will appear extremely uncoordinated, and will also cause the illusion of sunken eye sockets and increase the visual age.

Starting from the five senses of orientals, the width of double eyelids suitable for orientals should be 5-7mm, which is more natural. If the beauty seeker has a long face or is engaged in some modeling work, he can also try wider double eyelids, but the requirements must conform to his own temperament.
