It really depends how much you want to put on it. Lots of videos for intances will start to eat away at the memory. There's a school of thought that says you should always get more than you think you need. Luckily there are only three choices 16GB,64GB and 128GB. So if you follow the rule, you should get the 64GB even though it costs a bit more.
You iPhone can have a different amount of memory/gigabytes. It comes in 4 amounts. 8G, 16G, 32G, and 64G. Either one of those is the memory you should have. You can tell how many Gigs your iPhone is by looking on the back of the phone.
