Here is a brief glossary of the words you will hear a lot. They are typically all expressed in millimeters (mm).

Best Tips for Finding the Ideal Fit

Have a look at some of the best tips for finding an ideal fit below:

Choosing the Proper Frame Width

One of the most crucial measurements to get correct when purchasing new glasses is frame width. If you choose a too-thin frame, your face may appear excessively broad. If you choose one that is too wide, your face will appear too thin. It is crucial to find a frame with an arm's length or less between it and your face. Usually, the width of your lenses should almost exactly center your eyes.

Temple Arm Measurement

The arms or temples of glasses that don't fit properly will be either too loose or too tight. Your eyeglasses' temples should properly fit along your face and comfortably rest on your ear.

Obtaining the Ideal Measurements for the Lens’ Height and Width

Your eyes can be much improved with the proper lens height and width. Too wide-set lenses will make your eyes appear too close together, while narrow-set lenses will give them an unnaturally wide appearance. By ensuring that your eyes are centered within the lenses, choose eyewear with the proper lens height and width.

Finding the Correct Bridge Width

Obtaining the appropriate bridge width requires measuring the best bridge width.

Make sure the frame's bridge is pressed firmly against your nose. But you ought to take your unique facial shape into account.

The bridge width should be less the closer your eyes are placed. You could prefer a narrower bridge width if your nasal bridge is narrow or your eyes are close-set (15mm to 18mm). You could prefer a wider bridge if you have wider eyes or a wider bridge of your nose (18mm to 22mm). Consider the frame type and the bridge's placement concerning the brow line while shopping for new eyewear. If you have a higher nose bridge, pick a frame where the bridge is nicely aligned with, or close to, the frame's brow line. Select eyewear with a bridge that rests below the brow line or, if your nose bridge is lower, with a curved brow line.

Finally, remember that the width of your bridge may also depend on the thickness of the frame. Given that bridge width is measured from the inside of the frame, a frame with a thin rim and a thick rim with the same bridge width may fit your face rather differently.


How to Interpret Dimensions on an Antique Pair of Glasses?

Start with a pair of glasses you already own to determine your size. This is the quickest and simplest method. Check to see if they still suit your face comfortably. Frequently, the temple of your old spectacles will be imprinted with three sets of numerals, also known as the “ arm." Always list the measurements in the following sequence:

Span with lens size

Templar Stature

The fourth number occasionally printed on the temple arms corresponds to your lens height. The model or color of the frame may also be referenced by other numbers, letters, and names on some eyeglasses. Grab a ruler and take the procedures in the following section to double-check the numbers if you are unsure.

However, one important aspect of buying eyeglasses online that isn't specified on your glasses but that you must be aware of is frame width. Measure the horizontal frame span from one end to the other using a millimeter ruler to find the width of the frame.

Measuring the Bridge Width

Measure the space between the inner edge of one lens to the other horizontally (take care you do not just measure from the edge of the frames).

Typical measurements: 12mm to 31mm.

Calculating the Arm’s Temple Length

Determine the length of the temple arms starting at the hinge and ending at the point where the arm first bends. After that, measure from the beginning of the arm's bending to the end. Add the numbers together to determine your temple arm's length.

There are four typical sizes: 135mm, 140mm, 145mm, and 150mm.
