I use full, cob and pony sized bridles with my horses - cob fits my 15hh arab (he has a dainty nose and shorter cheeks - point from below ear to corner of mouth) and my 14.3 walking horse has a similar head and wears a cob. My 13.3 WelshX wears a cob - ALL of these horses wear the cob bridle just right which means that the bridle is not on the first hole or the last, but somewhere in the middle. A full bridle on these guys finds everything pulled up to the last or second to last hole and nosebands NEVER fit - they are always too loose and too long.
I personally would ask for the measurements of the bridle but it sounds like a cob may be the way to go. I think the browbands on both cob and full size bridles will still be 15 inches and the browband on the bridle in your pic looks a bit too big for your horses head. Those are easily replaceable. But from the looks of your horse, a cob sized nose band is probably in order - a full sized tightened to the tightest hole might be a little too loose.
I'd go for cob - you can always return it - Dover is great about exchanges.
