All measurements and the calculation results bellow are approximate and may differ slightly from the actual
measurements.

16:9

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

4:3

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
