Need help sourcing 3mm plywood

whether both the front and back are smooth

Ok, it seems the only hardboard that is available in the UK has a coarse mesh pattern on the reverse, whether it is tempered or not. This is a result of the manufacturing process, where wet boards are pressed under high temperature; the mesh underlay is required to allow steam to escape. The boards which are smooth on both sides are dried before pressing them, allowing the use of a smooth bed in the press. This is known as a "wet/dry" or "S2S" hardboard. Why is this type not available in the UK? I have no idea. Perhaps they don't make any in China.

By contrast, it took mere seconds to locate a supplier of such boards in Germany, and they're cheaper too, at just €8.63 inc. VAT per board! Now if only there was a way to order from them...

You mean like 7/16" + 1/4", or 3/4" / 5?

could do both just by looking at them but that's not wood sizes.

Well the second one I guess is 3/20", but that won't line up on the scale - curious to know how you did the first one, and what the answer is. Edit: ah, you convert the n/4 to n*4/16 and add, so 11/16"?
