How do i make a bookshelf and the measurements

There are lots of ways to make a bookshelf and lots of different sizes.  Could you post a picture of a bookshelf that looks like what you'd like to build?

What do you want it made of? How long and wide do you want it? Make these measurements and check Home Depot as they have shelving all ready made. Ask an associate at the store and they will help you find what you need.
