The pouch is large enough to fit most cell phones. Even the large beasts :-) Like the iPhone 6, 6+, 6S plus 5s, Samsung Galaxy S5, S4, HTC One X. Beware though, if you have monster case like the OtterBox, it will be a tight fit. Best to take it off. Your credit cards and ID's will also fit in the black pocket. The belt also has 4 elastic straps which are great for hanging other things - keys, race bibs, gel packs.
