The ZOOM sizes are nothing to do with the value you need to specify.
you need to specify the diameter of the lens.
eg your FILTER size.
hint...if you look into your lens you see it written on the end you look into. if not then it looks like the 18-55 zoom is a 52mm fit so thats the fitting you need not the 55mm.
filter sizes vary for each nikon lens. so if you have any other nikon lens, then the chances are it will have a different filter size fitting so your wide adapter will not fit it.
you can by conversion rings for filter Step up and Step down.
if you have already protected your lens with a UV filter, the size is also written on the filter edge
