Patio Size Calculator
Calculate patio area in square feet and square yards.
How to Use the Patio Size Calculator
Enter patio length and width to calculate surface area for pavers, concrete, decking or outdoor furniture planning.
Practical Example
A patio measuring 18 feet by 14 feet covers 252 square feet.
Factors That Affect the Result
Curved edges, steps, built-in planters, drainage zones and irregular boundaries can change the actual material area.
Frequently Asked Questions
Can I calculate an irregular patio?
Yes. Divide it into simpler shapes and add the areas.
Should I add material waste?
Yes, many patio projects include extra material for cuts and breakage.
Can I use the result for pavers?
Yes, then use a paver calculator to estimate quantity.

Planning Patio Area
Patio area is usually calculated from the finished footprint. Rectangular sections use length × width, while curved or angled sections can be divided into simpler shapes and added together.
When estimating pavers, concrete or decking, the surface area is only the starting point. Cuts, edge details, pattern layout and breakage can increase material needs. Measure the actual build dimensions, keep units consistent and apply a project-specific waste allowance rather than ordering exactly the calculated area.
