Hello,

The sizes of the sheets we have available are listed on our website under, Products (at the top) and then Plastic Canvas Sheets and Shapes. There should be a whole page of sheets listed there with 7 mesh, 10 mesh, 5 mesh and 14 mesh options. The largest we have in a 7 mesh canvas is 13" x 22" and I think that's about halfway down the page?! Thank you!
