For screen sizes between 40” and 500” not indicated on the above table, use formulas below.

Projection Distance = Screen Width (H) x Lens Magnification

 

Throw distance for GT10RL lens (m/feet) =H x 1.0

(For H between 0.8 m/2.7feet and 6.1 m/20.0 feet)

Throw distance for GT13ZL lens (m/feet) =H x 1.3

through

H x 1.6

(For H between 1.1 m/3.5 feet and 9.8 m/32.0 feet)

Throw distance for GT19ZL lens (m/feet) =H x 1.8

through

H x 2.4

(For H between 1.5 m/4.8 feet and 14.6 m/48.0 feet)

Throw distance for GT34ZL lens (m/feet) =H x 3.4

through

H x 5.2

(For H between 5.5 m/18.1 feet and 52.8 m/173.2 feet)
