Hello,
We are very sorry to see that you are disappointed with your canopy. The slant leg 12X12 canopy is the base size, as it features a 9x9 ft canopy top for 81 sq ft of shade. If you are looking for a bigger size canopy that provides more shade, then we recommend going with the 12x12 straight leg canopy instead. If you would like to discuss this in more detail, please feel free to contact us at 1-800-932-9344.
Thank you
