two-mat area, approx. thirty-six sq ft
坪 centers on a unit of area roughly the size of two tatami mats, about thirty-six square feet. It is a specific measurement term rather than a broad concept.
坪 combines 土 (earth, ground) with 平 (flat, level), suggesting a flat piece of land used as a unit of area.
Picture a flat (平) piece of earth (土) measured out to exactly two tatami mats: that's 坪.
For ヘイ, imagine laying out a flat area of hay (ヘイ) on the ground to mark off one 坪.
