Determine how much raw material is needed for your mat
We need to determine the sheet size of the raw material from which your mat will be cut. Using a tape measure, determine the total Length and Width of your mat and write down your final measurements. This measurement should include any portion of the mat that will be underneath the desk. After you determine the total length and width of your mat, you must round up to the nearest raw material sheet size. The raw material sheet size must be equal to or larger than your measurements.
