Most Accurate Land Calculator

Single Plot — Land Measurer

Enter side lengths in feet. For accurate area provide both diagonals (p, q).

Side a (top) — ft

Side b (right) — ft

Side c (bottom) — ft

Side d (left) — ft

Diagonal p (corner TL → BR) — ft (optional for accurate)

Diagonal q (corner TR → BL) — ft (optional for accurate)

Approximate area (avg-opposite-sides)

— sq ft

— acres

— acres & wesa

Accurate area (using diagonals)

— sq ft

— acres

— acres & wesa

Notes: Approximate method = ( (a + c)/2 ) × ( (b + d)/2 ). Accurate method requires both diagonals; if expression under the square root is negative the diagonals/sides combination is invalid.
