Frame Sizing Guide: Your Definite Guide to Choosing the Perfect Sized Eyeglasses

Are you ready to buy the perfect summer shades? Or maybe you are looking for a pair of prescription eyeglasses that will fit flawlessly and add a sophisticated charm to your personality. Regardless of your reason for buying eyeglasses, it is important that you know your frame size to find the perfect sized frames.

Apart from trying a whole bunch of glasses, luckily, there are some scientific methods available that you can use to gather your frame size information. This frame sizing guide is developed to help you understand how to measure your eyeglassesand choose a pair of eyeglasses that looks great and fits perfectly.

Step 1: Know the Size of Your Old Pair of Glasses

If you’re comfortable wearing your old pair of prescription glasses or sunglasses and are looking for an exact replacement, you may get one quite easily by measuring the dimensions of your existing shades or glasses. Usually, this frame size information is printed on the inside of the bridge or left temple — the part of your frame that goes behind your left ear. You should be able to find four different numbers, with each of them indicating the size of a particular component of your frame.

  • The first number represents the width or size of the lenses.
  • The second number indicates the bridge size.
  • The third number represents the length of the temples or arms.
  • The fourth number indicates the height of the lenses.

You can use this frame size information to order a frame from Safety Gear Pro.

Step 2: Finding Your Fit

If you’re ordering eyeglasses for the first time or if you believe that your existing pair of glasses is over- or undersized for your face, you may consider determining the ideal frame size on your own.

Measuring the Frame Width

Start with measuring the frame width. Wear a pair of glasses and see if your eyes are well centered in the width of the lenses. If the frame looks too narrow, you may consider a smaller size. Similarly, opt for a larger size if the frame makes your eyes look too close.

Here are some standard dimensions of lenses based on face width.

  • For narrow faces — 42mm to 50mm
  • For medium faces — 48mm to 53mm
  • For broad faces — 52mm and higher

Measuring the Bridge Size

Once you’re done measuring the width of the lenses, you should proceed to the next step of this framesizing guide which is to calculate the bridge size — the distance between the lenses.

Take your time with this step, as the right selection of bridge size and location will determine the fit of your frame. Bridge size can range from 15mm to 22mm, with smaller size suitable for individuals with eyes that are closely located. On the other hand, if you have wide eye sets, you choose a frame with a bridge size of 18 to 22 millimeters.

Another thing to consider is the location of the bridge. If you have a nose with a predominant bridge, you should choose frames with bridges that are even with your brow-line. On the other hand, if you have a flat nose, go for a frame with a lower bridge.

Measuring the Temple Length

Unlike frame width and bridge size, measuring temple length is relatively straightforward. An ideal frame should have temples that are long enough to sit comfortably over your ears. Temple length may range from 120 to 150 millimeters, with 135mm, 145mm, and 150mm being the most commonly used lengths.

Step 3: Choosing the Right Frame for Your Face

Apart from the frame size, the suitability of your frame for your face shape also influences the comfort and wearability of your eyeglasses. There are five basic face shapes: round, square, heart, pear, and oval. The following table will help you select the right frame based on your face shape.
