All measurements and the calculation results bellow are approximate and may differ slightly from the actual
measurements.
J 16:9
Q Calculation methods for 16:9
SW (m) = SD (") x 0.0221 SH (m) = SD (") x 0.0125
LW (m) = 0.0321 x SD (") - 0.04 LT (m) = 0.0388 x SD (") - 0.06
J 4:3
Q Calculation methods for 4:3
SW (m) = SD (") x 0.0221 SH (m) = SD (") x 0.0125
LW (m) = 0.0321 x SD (") - 0.04 LT (m) = 0.0388 x SD (") - 0.06
