坪 measures land or floor area as a fixed unit (≈3.3 m²), while 畳 counts tatami mats and is used more informally to describe room size (1坪 ≈ 2畳).
坪 is a smaller traditional unit for land area (about 3.3 m²), while 反 measures a larger plot (about 300 坪, roughly 992 m²).
坪 is the standard modern traditional area unit, while 合 is one-tenth of a 坪 and rarely used today.
坪 usually refers to an area unit, but 立坪 is the related volume unit (≈6 m³), so the two are easy to mix up despite differing in dimension.
