Calculating the throw ratio with TRC
1. For TRC > 1, amend the basic throw ratio formula as follows:
Throw distance
Screen width x TRC
Throw ratio =
2. Once a throw ratio is established, identify the matching lens from the table:
Throw ratios for 1080p and WUXGA Throw ratios for SX+ Throw distance range
0.67 : 1 xed lens 0.73 : 1 xed lens 1.1 m - 10 m (3.6 ft - 32.8 ft)
1.12 : 1 xed lens (3 m - 15 m) 1.21 : 1 (3 m - 15 m) xed lens 3 m - 15 m (9.8 - 49.2 ft)
1.12 : 1 xed lens (1.2 m - 2 m) 1.21 : 1 (1.2 m - 2.0 m) xed lens 1.2 m - 2 m (3.9 - 6.6 ft)
1.16 - 1.49 : 1 zoom lens 1.26 - 1.61 : 1 zoom lens 3 m - 15 m (9.8 - 49.2 ft)
1.39 - 1.87 : 1 zoom lens 1.5 - 2.02 : 1 zoom lens 4 m - 24 m (13.1 - 78.7 ft)
1.87 - 2.56 : 1 zoom lens 2.02 - 2.77 : 1 zoom lens 4 m - 24 m (13.1 - 78.7 ft)
2.56 - 4.17 : 1 zoom lens 2.77 - 4.51 : 1 zoom lens 9.1 m - 45 m (29.9 - 147.6 ft)
4.17 - 6.95 : 1 zoom lens 4.51 - 7.53 : 1 zoom lens 12 m - 80 m (39.4 - 262.5 ft)
6.93 - 10.34 : 1 zoom lens 7.5 - 11.2 : 1 zoom lens 12 m - 80 m (39.4 - 262.5 ft)
1.50 - 2.17 : 1 zoom lens 1.63 - 2.35 : 1 zoom lens 5 m - 25 m (16.4 - 82 ft)
1.72 - 2.71 : 1 zoom lens 1.86 - 2.93 : 1 zoom lens 5 m - 25 m (16.4 - 82 ft)
2.15 - 3.36 : 1 zoom lens 2.33 - 2.64 : 1 zoom lens 5 m - 25 m (16.4 - 82 ft)
3. Ensure the required throw distance is within the range of the matching lens.
Notes
TRC can only be applied if greater
than 1. If TRC is 1 or less, disregard
it and calculate the throw ratio using
the basic formula.
You can also use the information
in Appendix B: Lens Charts to
choose a lens.

part numbers, see Appendix A:
