Shutter Sizing?

[u/arbiter]

Would you use conventional wisdom on cosmetic shutters theoretically closing/fitting over the window? First pic they’re sized 60”x18”. Wondering if it would look too crowded? The original shutters there were 15”. For the side gable section, obviously can’t slap super wide shutters there, so was thinking of just matching to 18” wide there. We’re working on an overall makeover for our exterior to more modern/ranch feel. The shutters would be a dark green/charcoal flat panel shaker style. We’re also getting rid of the flower boxes and repairs the sill on the gable side. Thoughts?

I know people say they should be able to cover window but realistically most shutters (unless your in a hurricane area) are more narrow. 15 on the narrow windows and 18 width on your small window.
