Close but not really Much larger screen than an i-phone though. And much larger than a "Droid"(original Droid of that name), Droid Incredible and phones of that size.
Advantage of i-phone: All the same size. Makes accessories easier to make and get.
Advantage of Android: You can get the size of phone that suits you. Makes getting accessories harder though.
Pluses and minuses to them all.

Size comparison. Droid X to i-Phone:

In the first picture it looks a LOT bigger. When in reality(2nd picture), not that much.
