The single most consequential quantification is the overall width of the frames. Naturally, that width needs to accommodate your face comfortably. Your ocular perceivers should fall just about at the centre within that distance.
If the frames are too broad, they will make your ocular perceivers appear too proximate together. Similarly, frames that are too narrow will accentuate the width and overall size of your face. Opportune proportions give your face a balanced look.
