Square Yards Calculator

This page answers two questions in one pass: how large is the surface, and what will the material cost? You supply a length and a width; it returns the area in square yards and multiplies that area by the price of one area unit. Both answers are normal boxes, so the page also runs the other way — enter the yardage you need and it fills in the missing dimension, or enter your budget and it reports the highest price per square yard that still fits.

The unit matters more than people expect. A square yard is exactly 0.83612736 square metres, so the same surface reads larger in square yards than in square metres:$100\ \mathrm{m^2} = 119.6\ \mathrm{yd^2}$. Carpet fitters, turf growers and many landscaping suppliers still price in square yards, which is why the default result is yardage rather than square metres.

Two steps. First the rectangle: each dimension is converted to metres using the exact factor of its unit, and the two are multiplied to give square metres.

Then the area is written in the unit you chose for the yardage. For square yards the divisor is the square-yard constant:

The estimate reuses that area, but in the unit the price is quoted in, so the two sides of the multiplication match:

• $A_{\mathrm{m^2}}$ is the area in square metres, $L$ and $W$ are the two typed dimensions, and $f_L$, $f_W$ are their unit factors.
• $f_{p}$ is the size of the area unit the price is quoted in, so $A_{p}$ is the same surface measured in that unit and $p$ is the price you typed.
• $r_{p}$ and $r_{c}$ are the reference rates of the price currency and the result currency. When both menus show the same currency the ratio is 1 and only the two typed numbers matter.

Because the three boxes of the area step are tied together, the page is not limited to one direction. Fill in the two dimensions and the yardage follows; fill in the yardage and one dimension and the other dimension is solved instead. The same holds for the price step: give an area and a price and you get the total; give an area and a total and you get the price per area unit.

If you already hold an area in square metres or square feet and only need it written as square yards, the area converter does that conversion without asking you for two dimensions.

• Keep the tape horizontal. A tape sagging across a large room reads short, and the error is squared once you multiply it by the other side.
• Split the space rather than guessing. For an L-shaped room or a lawn with a shed on it, measure each rectangle separately and add the yardages. Adding 10% waste to a total is easier when each part is already separate.
• The area here is the net area. Tiles, boards and turf are cut, so buy above the number this page gives. For turf, the sod calculator adds a waste percentage and converts the result into rolls.
• Buying by volume instead? Gravel, topsoil and mulch are sold by depth, so multiply the area by the depth you want and convert that figure with the cubic feet calculator.
• Switching the result currency is cosmetic. The estimate is restated in the currency you pick; the material price does not change. Rates on the page come from a reference feed refreshed about once a day, so a card payment can still settle a little off the figure shown.
