WHY are Iphones always small-sized?

Of course there's a chance that a new Iphone will get bigger but the latest Iphone 5 is 5.0 inch
and there are people who prefer a bigger screen like me.

I think 5.0-5.5inch's is fine, but iphones are too small for me, why doesn't Apple make bigger-sized phones?

Added (1). EDIT: i made a mistake
but the latest Iphone 5 is 5.0 inch---> NOT 5.0inch, but 4.0inch

They have been going downhill since that guy died. I can't remember his name but he was the genuis behind everything i hear.

Apple seems to be of the philosophy that a phone is meant to be portable, and should be easy to use with a single hand. If you really want more screen space, they want you to buy an iPad.

They're not very small, they're of standard size and the size is just perfect for every hand.

  • Why are the harddrives on iphones and ipads so small? The maximum Harddrive space on the latest iphone is only 64gb? Why is that? With all the apps, songs and films you can download the maximum space apple gives you is 64gb? Why? Its nowhere near as much as a laptop and cast your mind back to the ipod classic you could get a 160GB harddrive on them. Does anyone know why apple went backwards?
  • When will iphone launch a larger sized screen phone? At least around 5 inches in size? 4 inch is too small. For now i have LG nexus which has 4.7 inch. I actually first purchased iphone 5 online but without even starting it or using it, i felt screen size is small and returned it back to get refund.
  • My iPhone 5 is taking iPhone 4 sized pictures When I take a picture, it doesn't fill up the screen of my iPhone 5. I have no idea why it's doing this. Basically, I'll take a picture of, say, a tree. When I view the picture, it has a black bar at the top and bottom - as if it had been taken with a 4S/4/etc. What's wrong with it?
  • How to print full sized photos? I have music sheets in my photo album and i print it wirelessly through my iphone to my printer but its only a fraction of the paper. How do i print a picture that takes up all of the sheet from the printer? I can't find the option only stuff like 16x10 or whatever. How do i make it take up the whole page?
