You need to sit on a bike to confirm that detail, so go to Halfords or your local bike shop and ask to try one or two but say you are planning to buy in the near future and just need to verify the size and type to go for. You must identify both the frame and wheel size that fits your requirement e.g. Mountain bikes can have small wheels whereas for touring or racing bikes you need large wheels. If your are still young and likely to grow taller go for the largest size that suits - say 17" frame Mountain bike.
