Went to the AT&T store today to browse similar sized phones, equipped with cutouts of the iPhone 6 and iPhone 6 plus sizes. Here are the phones I found were the closest in size.
iPhone 6 = Amazon Firephone -- front size almost identical. iPhone 6 will be thinner though. Though the pic makes the Firephone look much larger, the front of the Firephone is pretty much *identical* in size to the front of the iPhone 6.
iPhone 6 = LG G Flex -- front size very close (iPhone a bit narrower, will be thinner, and not curved). Height is basically identical. But this should give you an idea of the phone's size.
