Select more than one if you need to add separate rooms or sections.<\/li>\n<li>Under each <strong>Area<\/strong>, choose a <strong>Shape<\/strong>: Rectangle, Triangle, Circle, Trapezoid, or L-shape (two rectangles). The calculator shows the measurements that shape needs.<\/li>\n<li>Enter <strong>Length \/ base 1 \/ diameter (A)<\/strong> and, when shown, <strong>Width \/ base 2 \/ height (B)<\/strong>, <strong>Height \/ length 2 (C)<\/strong>, and <strong>Width 2 (D)<\/strong>. Choose the <strong>Unit<\/strong> beside each measurement; you can mix ft, in, yd, m, and cm.<\/li>\n<li>Set <strong>Waste allowance<\/strong> if you want to include extra material. Enter a <strong>Price per square foot<\/strong> for a cost estimate, or clear that field to omit the estimate.<\/li>\n<li>Read <strong>Total area<\/strong> for the measured footprint, <strong>Area including waste<\/strong> for the adjusted quantity, and <strong>Area breakdown<\/strong> to check each shape separately.<\/li>\n<\/ol>\n<h2>What square footage tells you<\/h2>\n<p>Square footage measures the size of a two-dimensional surface in square feet. A 12 ft by 10 ft rectangle covers 120 sq ft; its perimeter is a different measurement and cannot tell you its area by itself. Square footage is useful for comparing room sizes, estimating flooring coverage, or measuring a lot divided into simpler shapes.<\/p>\n<p>This calculator reports the same total area in square feet, square yards, square meters, and acres. These are unit conversions, not four different measurements: 9 sq ft equals 1 sq yd, and 43,560 sq ft equals 1 acre. The acre result is rounded to six decimal places, so very small areas may display as 0.000000 acres.<\/p>\n<p>The <strong>Area including waste<\/strong> result is a planning quantity rather than an increase in the surface itself. For example, adding 10% waste to a 120 sq ft floor gives 132 sq ft to budget for cuts and offcuts; the floor still measures 120 sq ft. The estimated cost multiplies this adjusted quantity by the entered price, so it changes when either the waste allowance or price changes.<\/p>\n<h2>Measurement tips and limitations<\/h2>\n<ul>\n<li>For a triangle, enter its base as <strong>A<\/strong> and its perpendicular height as <strong>B<\/strong>. A sloped side is not the height unless it meets the base at a right angle.<\/li>\n<li>For a circle, <strong>A<\/strong> is the full diameter across its center, not the radius. The calculator does not use <strong>B<\/strong> for a circle.<\/li>\n<li>For a trapezoid, <strong>A<\/strong> and <strong>B<\/strong> are the two parallel bases; <strong>C<\/strong> is the perpendicular distance between them.<\/li>\n<li>For an L-shape, measure two <strong>non-overlapping<\/strong> rectangles: <strong>A \u00d7 B<\/strong> and <strong>C \u00d7 D<\/strong>. If they overlap, their shared portion will be counted twice. An irregular space can also be divided into separate shapes using <strong>Add another area<\/strong>.<\/li>\n<\/ul>\n<p>Measure the surface you actually intend to cover. For flooring, exclude openings or fixed features only if they will not be covered and the difference matters to your estimate. A 10% waste allowance is a common flooring starting point, but the right amount depends on the product, layout, cuts, and installation method. This calculator does not account for package sizes, minimum order quantities, labor, or tax.<\/p>\n<p>Area alone does not give the amount of a material with thickness or depth. Once you know a ground area, use the <a href=\"https:\/\/wpcalc.com\/en\/life\/gravel-calculator\/\">gravel calculator<\/a> or <a href=\"https:\/\/wpcalc.com\/en\/life\/mulch-calculator\/\">mulch calculator<\/a> for a depth-based estimate. For wall coverings, the <a href=\"https:\/\/wpcalc.com\/en\/life\/wallpaper-calculator\/\">wallpaper calculator<\/a> addresses roll coverage rather than floor area.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Calculate the square footage of up to five rectangles, triangles, circles, trapezoids, or L-shaped areas.
