Size Guide
Eyeglass size guide
Are you about to select your new glasses, and you're wondering: what should be the perfect size? This is an important consideration, especially if you're thinking of buying them online without trying them on first. Here you'll find the
answer, whether you already have a frame but don't know the size, or whether you're starting from scratch.
How to read your eyeglass size
If you already have a pair of sunglasses or eyeglasses and want to know their size, check the inside of the temple.

The three numbers you see correspond to the lens width , the bridge width and the temple length .

The width of the lens is also called the caliber and corresponds to the size of your glasses .
The bridge measurement refers to the part of the frame that rests on the nose and connects the lenses.
The temple is measured in its entirety, from the end that rests behind the ear to the junction with the front of the glasses.
Please note: These three measurements are expressed in millimeters .
On SunglassUp.it, the size of the glasses is shown on the product sheet, above the ADD TO SHOPPING BAG button.

How to find your size

Place the long side of the paper in the center of your nose, align the short side with your eye, and look at yourself in the mirror.



How to know if your glasses are the right size
When you wear the perfect glasses, you can feel it: they're comfortable and enhance your image to the fullest. However, if you're not entirely sure about the size, here are some helpful tips.
If your glasses slip, there's something wrong. They're probably too big. With the correct size, the frame fits snugly on your nose, without being too tight. The temples should be neither too tight nor too loose at the temples.
Put on your glasses and look at yourself in the mirror: your pupils should be aligned horizontally in the center of the lenses.
If the glasses move easily when you smile when pressed against your cheeks, you may need a different size that best suits your face.
Speaking of eyebrows: personal style matters here. While many recommend keeping the frames below the brow bone, we've noticed that some people prefer glasses that cover them, especially oversized models with distinctive profiles or sunglasses. The decision is yours!
