Yes. I find this curious as well. There have been frames that I think are wide enough to fit my mug based on the enumerated size but just don’t look right IRL (in real life).I always find it interesting that, despite having the measurements as a guide, quite a few frames that should work with large faces dont. I have the Kobo too and they are marginal on my face. Cash doesn't work, need to get rid of those. If you ever have the chance to try on the Standiford, they work surprisingly well, again for my large face
