Question: how do i calculate how much backsplash i need?
Answer: Multiply the width and height to find the total area in inches, then divide by 144 to find the amount of square feet needed (amount of inches in a square foot). For example, if your space is 48″ (width) x 18″ (height) = 864. 864/144 = 6 square feet. Be sure to measure every area that needs tile and add them together!
