how to choose men's glasses frame size according to face shape?

The common frame sizes for men and women can vary based on several factors, but here are some general guidelines:

For Men

1. Eye Rim Width

1. Typically, men's frames have an eye rim width that ranges from 48 - 56mm. A 50 - 54mm width is quite common. For example, a man with a medium - sized face might find a frame with a 52mm eye rim width to be a good fit. Larger - faced men may opt for widths closer to 56mm, while those with smaller faces could choose frames around 48mm.

2. Nose Bridge Size

1. The nose bridge size (DBL - distance between lenses) for men usually falls in the range of 16 - 18mm. A 17mm nose bridge is a popular choice as it can comfortably support the frame on the average - sized male nose. However, for men with wider or narrower noses, the bridge size may need to be adjusted accordingly.

3. Temple Length

1. Men's temple lengths generally range from 140 - 150mm. A 145mm temple length is quite standard and suitable for most adult men. If a man has a larger head circumference, a temple length closer to 150mm might be more appropriate, while those with smaller heads may prefer 140mm temples.

For Women

1. Eye Rim Width

1. Women's frames often have an eye rim width in the range of 46 - 52mm. A 48 - 50mm width is very common. For instance, a woman with a small to medium - sized face may find a 48mm eye rim width flattering, while those with slightly wider faces could choose a 52mm width. Fashion trends also play a role, with some women preferring smaller, more delicate frames (towards the 46mm end) or larger, statement - making frames (up to 52mm).

2. Nose Bridge Size

1. The nose bridge size for women usually ranges from 14 - 16mm. A 15mm nose bridge is a typical choice as it can comfortably fit the average - sized female nose. Similar to men, women with wider or narrower noses may need to select a different bridge size.

3. Temple Length

1. Temple lengths for women are generally 135 - 145mm. A 140mm temple length is quite common and suitable for most women. Women with smaller heads may find 135mm temples more comfortable, while those with larger heads may need 145mm temples.

It's important to note that these are just general ranges, and individual face shapes, head sizes, and personal preferences can lead to significant variations in the ideal frame size. Additionally, the availability of frame sizes may vary among different eyewear brands and styles.
