Don't hate your hands! They're doing their best for you! Every shape has advantages and disadvantages. Be savvy about what you do best and try to solve playing problems through your strengths. I have VERY small hands. Actually, the smallest of any pianist I know, and I play almost everything I want to. Some things are more difficult for me, but other things are easier, and I feel comfortable in certain repertoire that someone with normal or large hands would find confining and awkward. It doesn't matter what's ideal, partly because you have to determine: ideal for what? Lizst? Mozart? Big sprawling transcriptions or intricate polyphony with closely-crossed hands? And partly because, if there were such a thing as ideal hands and a person had them, it still wouldn't make the person a great artist at the piano. There are so many other factors which have nothing to do with physical characterics: Musical ear, taste, artistic knowledge and experiences, investment of time and energy, wise teaching... blah blah blah. If you have something to express with your music and the techniques to express them, your hands will never hold you back.
