Although the thickness of the sheet can vary by +/- 0.2mm in some areas, it is fairly constant for most applications. close enough but not perfect 200x300. and has a protective film on top so it can be cut open and still stay clean. I've used these panels for everything from an RC track frame to a cover for my motorcycle. They work great and I will happily use them again when I run out of options to use the current sheet I have.
