What Are the Types of Double Eyelids?
Double eyelids significantly enhance the appearance of the eyes. Prior to undergoing double-eyelid surgery, it is essential to understand which type of double eyelid best suits your facial features. Broadly speaking, there are three main types of double eyelids: parallel, crescent-shaped (or “moon-shaped”), and fan-shaped (or “open-fan”). The choice between a parallel or crescent-shaped double eyelid should be based on the individual’s facial structure. After surgery, adequate rest is crucial for optimal recovery.

What Are the Different Types of Double Eyelids?
Parallel Type
The double-eyelid crease runs nearly parallel to the upper eyelid margin. When designing the crease, the outer end should not extend beyond the lateral canthus. This type is ideal for women with relatively large eyes, high brow ridges, greater distance between eyebrows and eyes, and thin upper eyelids.
Fan-Shaped (Open-Fan) Type
One of the most classic double-eyelid styles—often described as “peach-blossom eyes”—this type is especially popular among young women. Its defining feature is a narrower inner fold that gradually widens toward the outer corner. It suits individuals with moderate spacing between eyebrows and eyes, thin eyelids, eyes angled slightly upward relative to the horizontal plane, and subtly uplifted outer canthi—conveying brightness, vitality, and an alert, spirited expression.
Narrower Inner Fold, Slightly Wider Outer Fold
This type is suitable for individuals without epicanthal folds and with relatively close spacing between eyebrows and eyes—more commonly seen among Western women. “Partially double”: one-third to one-half of the eyelid remains single-fold, while only the outer portion forms a distinct double fold. This configuration imparts a charming, alluring, and sensual appearance.
European-Style Double Eyelid
This style is anatomically suited primarily to European facial bone structure—dictated by the physiological anatomy of the tarsal plate. Additionally, Europeans typically have markedly high brow ridges and eyebrows positioned close to the eyes, resulting in wide, pronounced double eyelids. However, this style is generally less suitable for East Asian women.
For Asians, naturally occurring double eyelids tend to be narrower and less conspicuous when the eyes are open—often appearing more localized. Therefore, Asians undergoing double-eyelid surgery typically opt for either the parallel or mildly fan-shaped (open-fan) configuration.
