450x150mm (fits a fullsize or a TKL with a separate numpad).
370x150mm (fits under a TX-84/87 perfectly).
Due to the size of the large mat, we decided to cap the shipping cost for 1 big mat to $9.99/$10.99/$11.99 (depends on your state) for FedEx Ground option. Please note that California buyers may see the benefits of using USPS instead.
