Do dimensions on a pan faced sign change when formed?

[Big EZ Signs LLC]

Howdy all,

I'm looking at ordering a pan faced sign for customer. I'm sourcing the acrylic myself, and looking for a subcontractor to vacuum form the pans for me. What I wanted to know was, if I start with a 5' x 5' sheet, will the dimensions change ( i.e. become larger ) when formed on the vacuum table, say to a depth of 1"?

Thanks,

Sign Nutz

I have always ordered the sign with the depth of the pan and the width of the flange specified.
