Every state constitution is longer than the federal Constitution. The shortest state constitution is that of Vermont, with about 8,419 words–about 2,000 words longer than the U.S. Constitution. The longest is that of Louisiana, with 184,053 words. The average state constitution is about 27,000 words–about four times the length of the U.S. Constitution!
State constitutions often have sections that are equivalent to the Bill of Rights. Remember, state constitutions can GIVE more rights than the federal Constitution (for people in that state), but neither state nor federal government can infringe upon your rights in the Constitution (with just a couple of exceptions–there’s no guarantee in states of a grand jury or of a right to trial by jury in civil cases–though most states do follow these principles.)
States also tend to have law-like provisions regarding foresty, natural resources, labor, social welfare, education, etc. That in part is why they are so long, and are amended so frequently.
