You can resize to any exact specific size you what by cropping and exporting from iPhoto with a maximum dimension
eacty as I previously posted
Easy in iPhoto
Crop to the dimensions you want (250x200 for example) and export (file menu ==> export) using a custom size setting the max dimension to what you want (250 in this example)
It pays to read the thread before posting that you can not do something that has aready been explained in the thread

It pays to understand the difference between resizing and cropping before telling someone off for justifiably ignoring a non-answer.
It's somewhat useless cropping a large high-resolution but poor quality photo (as camera phones tend to create).
Resizing makes the same image take up less space (for storage, sharing and data usage), without reducing quality by much because the lens of a typical camera phone means the pictures they take often contain lots of redundant information in their excessively high-resolution files.
If you "simply crop" such a portrait image to e.g. 250x200 you're unlikely to get much more than a large eye in your picture.
It's unfortunate that iPhoto doesn't provide such a trivial feature.
However, a few answers have indicated that an image can be resized by exporting and either resizing during export or later in Preview.
