Frame width is the primary way we determine fit. It’s the horizontal diameter of the entire frame width.
*Note that you won’t find this number on your glasses.
Other Technical measurements
Like most brands of glasses, the measurements of eyebobs glasses can be found on the inside of the temple arm. The first number indicates the lens width (46mm) and the second number is the bridge (23mm). If you already have a pair of glasses you like, you can use those measurements as a reference.
