Size and Fit guide
Finding the right frame size is an important part of buying glasses online. Fortunately, it’s also very easy! Below is a helpful guide to help you understand the size and dimensions of your glasses when looking for your next pair of eyeglasses or sunglasses.
To ensure that your frames fit correctly, you must first determine the size of the frames that will work best for you. The best way to do this is to measure a pair of frames that you already wear and feel comfortable in.
You can usually find the measurements on the inside of the temples of your glasses. Some people also refer to this part as the ‘arm’ of the glasses. Frame sizes are usually displayed as three numbers separated by dashes, for example 48-19-140. these three numbers reflect the measurements for different parts of the frame.
- Lens Width This is the horizontal width of each lens measured at its widest point. Also known as eye size, it is usually between 40mm and 60mm.
- Bridge WidthThis is the distance between the two lenses. In short, the bridge width is the space between the frame and the bridge of the nose. Bridge sizes range from 14mm to 24mm.
- Leg (Arm) Length This is the length of the leg from the hinge to the top of the leg, including the curved portion at the ear. Arm lengths are typically 120 mm to 150 mm.
- Lens HeightThis is the vertical height of the lens. The measurement is taken from the widest part of the lens in the frame. Lens height is especially important when measuring bifocal or progressive lenses.
- Frames that are too narrow will make your face look wider, while frames that are too wide will make your face look narrower. This is one of the most important factors in finding a pair of glasses that fit your face. Look for a frame that is slightly wider than your face – no more than a finger’s width between the temples and your face. Anything wider than that means the frame is too wide.
What is frame size?
The frame size refers to the horizontal width of the frame,
measured between the center of the left and the right hinge. Our frames come in one or multiple sizes. See the range in the chart below:
Size | Hinge to hinge (mm)/(inches)
XXS | <121 / <4.8 XS | 121-124 / 4.8-4.9 S | 125-128 / 4.9-5 M | 129-132 / 5.1-5.2 L | 133-136 / 5.3-5.4 XL | 137-140 / 5.4-5.5 XXL | >140 / >5.5
How do I know the right size for me?
To find your correct frame size, use a ruler to measure the hinge-to-hinge distance of a pair of glasses
that you already own and that fits you well. Consider the tolerance range of +/- 4mm.

If you already own a pair of glasses, you will see some numbers engraved on the inside of the eyewear temple:
