12×12 gazebos

For most patios, buy an aluminum-post 12×12 with a steel roof, like Domi’s hardtop with drainage gutters: curtains and netting come in the box, and the roof and frame are covered for five years. If you get heavy snow or strong wind, Backyard Discovery’s cedar Arlington or Barrington costs more but is rated for 100 mph once anchored. Either way, the floor between the posts is closer to 10 by 10 than 12 by 12.
