AbstractWe introduce a method to measure leaf area from plant leaves using a personal computer, and a handy scanner with corresponding software. Measurement of standard areas revealed a very high correlation (r = 0.999) between the number of measured pixel (1540 pixel/cm2) and the tested areas. Comparisons of scanner derived measurements with those from a standard area meter instrument revealed a high correlation (r = 0.998). Our method is a cheap and efficient alternative to the conventional area meters and can also replace more laborious ‘home‐made’ methods of measuring plant leaf
