When it comes to selecting the size and shape of your cutting board, it's simply a matter of personal preference. Think about whether your kitchen countertops have enough space for the size you are considering. You need a cutting board that will stay firmly in place on your kitchen countertop. When it comes to standard chopping boards, they are typically rectangular, measuring 17 inches long by 11 inches wide and 0.75 inches thick. If your kitchen countertops have plenty of space, you may want to opt for a larger cutting board for even better results. A large cutting board can measure up to 20"x15"x1.75" or 24"x18"x1". Moreover, the thickness should also be examined. The most suitable thickness for an end-grain wood cutting board is between ¼ and 2 inches.
