Is the Iphone 5 the same size as the Samsung Galaxy S3?

I'm looking to buy a case that I like but it says only compatible with Iphone 5 and I have a Galaxy S3.

Iphones are a lot smaller I think and much more square in comparison to the s3

No. The galaxy s3 is MUCH MUCH bigger then the iphone 5… Try ebay for a good case

Totally different sizes dude. This is my favorite case brand and they offer cases for both.http://www.spigen.com/

The s3 is much bigger
