You can opt any stream after 10th to become interior designer, but ideally you must choose science stream as it will make you analytical and in such profession you need to deal with different types of materials, in such case science will help you a lot. Also, you must emphasize to learn language as communication is very important part of any designer. For more information you can go through this link
