One of the most common issues people face when shopping for eyewear online is finding the perfect bridge fit. A bridge that’s too tight can pinch the nose and cause your frames to sit too high on your face, while a bridge that’s too wide keeps sliding down your face all day (talk about annoying!).
That’s why we’re here with 10 tips to help you find your perfect bridge measurement.
What is a bridge measurement?
Before we get started, let’s make things clear: the bridge measurement is the distance between the inside of one lens to the other — the part of the frame that sits just above (or on) your nose.
Acetate vs. metal: which offers the simpler bridge fit?
Generally, getting the right bridge measurement is much more important when it comes to acetate frames than with metal glasses. If you prefer metal, you’ve got it easy! Metal frames’ bridges often come with adjustable nose pads that can be tightened or loosened to suit a variety of nose sizes.
Can I use my current pair of glasses to find my bridge measurement?
Yes! If you currently wear acetate frames, your bridge measurement should be printed right on the glasses. You can usually find this number either along the arm or the nose bridge itself. Traditionally, the middle number corresponds to the bridge measurement and is between about 16-21mm on most glasses. If your frames fit well, this number will work for you across the board.
Can’t find your bridge measurement, or shopping for glasses for the first time?
Look in the mirror to see where your nose bridge starts and how wide or narrow your nose is. One helpful trick is to take a selfie of your side profile! If your bridge is low (level or below your pupils), your bridge size will be a low number (maybe 16-18). If it is high (above your pupils) or if it is wider than average, you will need a larger bridge number (maybe 19-21)
Nose bridge position is just as important as size
It is also important to look at location of the bridge on the frame. If you have a high bridge, frames with a bridge closer to the browline are great! If you have a low bridge, frames with a curvier brow or a lower bridge would be a better choice.
Frame thickness also plays a part
Because the bridge measurement is measured from the inside of the frame, a thick-rimmed frame with the same bridge size as a frame with a very thin rim will not fit the same, it might actually be too small. For example, if you know your bridge is 17mm and you’re looking at a chunky frame with a 19mm bridge, it is very likely that it will be a suitable size for your bridge because it takes into account the extra rim.
So, after all this, if you’ve concluded that…
Seven. Your bridge is small: look for something in the 14-16mm range.
Eight. Your bridge is medium: you’ll be best suited to a bridge between 17-19mm.
Nine. Your bridge is large: your size would be 20-23mm.
Ten. Once you’re confident, its time to go shopping for your new pair of glasses! Using our handy size filter found on the left hand side of our glasses homepage, you can search for only the frames that suit your size.
