How to use it

  2. Enter patio height in feet.

  4. Enter brick height (in) – default 8, then click Calculate.

What it does – The calculator takes the length and height of your patio in feet and the dimensions of a standard brick (16 in × 8 in) and instantly tells you how many whole bricks are required and the total square‑foot coverage. Why it matters – Knowing the exact count prevents over‑ordering, saves money, and avoids project delays. Reading the results – Units needed is the number of whole bricks you must purchase; round up if you prefer a safety buffer. Area shows the patio size the bricks will cover in square feet, confirming your input. No mortar gap or waste is included, so add a small percentage yourself if you want extra. Use the result to compare supplier quotes, plan delivery dates, and ensure you have enough material before you start laying the patio.

Pro tips

  • Add 5‑10 % extra bricks for cuts and breakage.
  • Always round up the unit count; you can’t buy a fraction of a brick.
  • Verify the brick dimensions with your supplier before entering them.
  • Order a full pallet to reduce shipping costs when the total exceeds 500 bricks.

Real-life examples

  • A homeowner planning a 12 ft × 8 ft backyard patio.
  • A landscape contractor estimating material for a client’s commercial walkway.
  • A DIY enthusiast buying bricks for a raised garden bed border.
