Making Sense Of Frame Measurements

Thursday, 02 April 2020

In this blog post, we will demystify the process of working out what size of frames you should be looking for.

This is perhaps the most important skill when it comes to buying eyewear online. Whilst almost 90% of the global population own at least one pair of sunglasses, I would wager that less than 1% would actually know what size they are. Compared with measurements like your shoe size, shirt size or dress size, which are known almost ubiquitously, eyewear sizing can often seem confusing to even the most experienced online shoppers.

Measurements on glasses frames

Where do you start when sizing up a glasses frame?

The first thing we recommend is to take a look at your current favourite glasses or sunglasses frames in a bit more detail. Most frames that have been manufactured over the last 40 years will have some extra information relating to their sizing printed or embossed on the inside of the left arm. If you can’t see any details here they could also be under the inside of the nose or right at the base of the arm too.

What you are looking for is something like you can see in the image below…

Inner arm of a frame

As you can see there are quite a few numbers on this frame, so which one’s are the frame measurements?

48 – This relates to the lens width in mm.

22 – This is the bridge width in mm.

150 – This is the arm length from the temple to the end of the arm in mm.

Blue Demi – This is the model number of the frame.

Now for the fun part, you can compare these measurements against a frame that you love from our collection. All our vintage glasses and sunglasses frames have got 5 measurements against them within their product descriptions to help you make the right choice.
