Is there an ideal nostril width? For example, should your nostrils line up with the inner corners of your eyes?

I believe what you are referring you is known as the alar base - the total distance from the outer aspect of the nostrils.  You are correct in stating that the ideal base width should correlate with the inner aspect of the eyes (medial canthus); however each case is evaluated on an individual basis.  Sometimes maneuvers performed during surgery will actually narrow that distance without having to make incisions (known as lateral crural steal).  Consult with a Board-Certified plastic surgeon who will be able to make that distinction.

Thank you for your question.Back in the 70's, various studies were done measuring all types of relationships in the human's face called anthropometric measurements.  However, this was done mostly on caucasians.  The results of those studies were as you indicated in your question: the inter-nostril width should be approximately the same as the inter-canthal (inner eye corner) distance.Now in my practice in Toronto, I use those guidelines with 'moderation'; I ALWAYS account for the ethnicity of my varied patients' practice (Toronto is very multicultural, as you know), their wishes, etc.  More importantly, I aim for harmony between the various components of one's face - which I call "artistry".One must also take into considerations that the inter-canthal distance may be shorter or longer than the average person.  So yes, there is variation also for the inter-canthal distance.  This can also be modified, although it is a much more complex procedure.Hope this helps!

In a very general sense what you say about nostril with is true. Their basic relationships of the face that are considered attractive and can be described numerically. Video imaging would be a good way to see how this translates to your own face. The nostrils can be narrowed independently to give you some idea of this change in your own particular situation.
