Tips for measuring space for new countertops include measuring from the back wall and adding three-fourths of an inch to the final measurement to account for overhangs. An extra inch that can later be trimmed off should also be added when measuring space for countertops that intrude into free space.
Making individual measurements of each section of countertop leads to more accurate dimensions. Depth should be measured from between the edge of the countertop and the wall. The length of a countertop is the long horizontal space between appliances. Additional materials may be required to create a backsplash. Adding 4 inches to depth measurements is usually sufficient for those who may be unsure about the size of their backsplash.
