Measuring Guide & Size Chart
How to use the measuring guide: Measure your cabinet inside from left to right; this measurement will be your width (W). Measure your cabinet from front to back on the inside; this measurement will be your depth (D). Please check for any obstructions such as plumbing running through the bottom of your cabinet, water lines, outlets, electrical junction boxes, etc. You will need to avoid these by ordering a smaller size or modify the mat to accommodate them.
Example: Your cabinet interior is 30" 7/8 inches x 22" 3/4 inches. Even though it is very close to our 31" 1/4 x 22" 1/4 size and the depth is correct, your available width is too small to accommodate the 31" 1/4 mat so you will need to size down to the next closest size (width) with the same depth, our 28" 1/4 x 22" 1/4 mat.
(You are trying to find the largest mat that will fit in your cabinet WITHOUT going over your interior dimensions. The sidewalls are flexible but the mat can never be smaller than the footprint which is shown in the chart as the "min" dimension)
