Calculate the area of a trapezoid from base 1, base 2, and height. Estimate square feet, square inches, square yards, square meters, perimeter, median, waste, material quantity, and project cost.
Base and height:
The calculator adds base 1 and base 2, divides by 2, then multiplies by the height to estimate trapezoid area.
Median:
The median is the average of the two bases. Trapezoid area can also be calculated as median × height.
Perimeter:
The calculator adds base 1, base 2, left side, and right side to estimate the total distance around the trapezoid.
Material estimate:
The calculator adds your waste percentage, divides by coverage per unit, and estimates total project cost.
A trapezoid area calculator helps estimate sloped or angled spaces for land sections, gardens, concrete pads, flooring, tile, roof sections, walls, patios, and landscaping.
It can help calculate square footage, compare area units, estimate material quantity, add waste, and estimate project cost.
Your result shows the trapezoid area, median, perimeter, area with extra waste, estimated pieces or units needed, and estimated cost based on the values you enter.
Add the two bases together, divide by 2, then multiply by the height. For example, bases of 14 feet and 8 feet with a 6 foot height give an area of 66 square feet.
The formula is Area = ((Base 1 + Base 2) ÷ 2) × Height.
The median is the average of the two parallel bases. You can calculate it by adding base 1 and base 2, then dividing by 2.
Add all four sides together: base 1, base 2, left side, and right side.
Yes. Angled shapes often create cuts and offcuts. For flooring, tile, roofing, pavers, sod, fabric, or concrete planning, adding 5% to 15% extra is commonly helpful.
