Measurements were supposed to be a 20x14 but doesnt seem to measure up correctly.  This I used to cover a 10x20 pen due to having a hurricane heading our way and knew if I just had it on poles, it would flap away. This seems very small compared to what it should be and has no other grommet holes except for the 4 corners. For this size, it should have a couple more on edge in middle as well. Seems very thin also. It is nice but do not feel it was correctly represented.
