Question How do you decide thickness of Acrylic to use?

Hey there!
So I lurk here (quite a bit) and have been searching through the threads for a guide on using acrylic, specifically what thicknesses are suitable for larger jobs. Currently for me, a large job is about 60" in the biggest direction. When I started years ago, we rarely did this sort of thing, but as I've been gaining confidence (and table space) I'd really like to go forward with some solid recommendations.
Could anyone point me towards a good thread, or a guide elsewhere?

For instance, I'm currently about to order acrylic for a 56 x 36 frame and wondering if .100 is suitable, or if I should go up to .118 thickness. It's for a shadowbox, inner walls about 1" deep.
I usually order my acrylic through DonMar.
Thanks! So grateful for everything I've learned here.

A minimum of .118', thicker if it is available. The .098" will flex too much. I only use it on smaller frames where the rabbit is thin.

I always use 0.118" for just about everything. I only go thinner if special circumstances calls for it. 0.118" does not flex as much and I'm already charging the customer more $$ for acrylic.

Thank you everyone! I'm going with the .118 and will do so from now on!

(And Larry, I've bookmarked your site to do some reading later.)

AND- if you cut the frame and are able to measure it BEFORE you order your plexi, Don Mar gives a courtesy cut on a 48 x 96 sheet of any plexi I believe.

The marketers of framing-grade acrylic provide size/thickness recommendations in their technical specifications.
