Oh, gosh, wish I could tell you for sure it would fit. But this is my first Kindle and it is an HD. It fits that perfect ! Love it. I would say to just check the measurements given on this one and the Kindle brand one for the Fire. Sorry I couldn't be more help.
Echo the first answer, the two kindles are not the same size or shape for that matter--the first fire is more box shaped and the new HD tapers more in the back not unlike an iPad. The case fits the Fire HD so "perfectly" you would probably not be happy with the fit. Plus there are lots of choices out there for both versions.
Hello Cythia, the short answer is I dont know. However a quick look at the Kindle page on Amazon there is a "spec" page - take a look and scroll down to the diamensions, the Kindle Fire is slightly smaller than the HD. In my opinion, I would not buy this case for the Kindle Fire as I believe the width at some 15mm less than the HD would no be secure
