Acrylic thickness vs frame size question

I currently use .098" (2.5mm) inch Cyro acrylic but I am starting to venture into frames that are larger than 24x28. I think most custom framers are using .118" (3.0mm). I was curious if any of you have any recommendations on acrylic thickness vs. frame size to reduce the chance of bowing.


The cost difference from LJ is less than $13 per sheet so I feel that you should definitely go with the thicker Acrylite on larger framings. You will realize about the same markup on either thickness per size and you won't have nearly the worry with bowing or flexing with the thicker acrylic.

The clarity is the same on both and the added thickness will not add that much weight to larger sizes when you consider that the equivalent weight of the same size glass would be alot more. And you have to be aware of the break factor on large sizes of glass.
