— Projector Throw · Corporate AV
Boardroom — 100-inch 16:10 screen, ceiling mount
Problem. A corporate boardroom with a 100-inch 16:10 screen and a ceiling-mount throw of 3 m needs a projector specified for daytime ambient lighting.
Answer. Throw ratio around 1.4 with 4000+ lumens recommended for a moderately-lit boardroom. The calculator anchors the install before the AV consultant builds the BOQ.

How this preset reads — the engineering view.
Boardroom projection differs from cinema in one decisive dimension: ambient light tolerance. A boardroom is rarely fully blacked out — pull-down blinds and circadian-friendly indirect lighting are the default. The brightness calculation should assume 'moderate ambient', not 'dark cinema'.
This preset assumes a 100-inch 16:10 screen (2.15 m wide) at 3 m throw — typical for a 5 × 6 m conference room with a 3 m ceiling. The required throw ratio is around 1.4, which suits most short-throw to mid-throw business projectors and ceiling-mounted laser fixtures.
Lumens: 4000+ ANSI is the typical specification for this geometry against partial daylight. Modern laser projectors hit that comfortably and bring the secondary benefit of 20 000+ hour service life — meaningful in an environment used daily for the next decade.
Out of scope for the throw calculator: source switching (HDBaseT vs IP-AV decision), control protocol (Crestron vs Q-SYS vs DSP-only), microphone-and-camera placement and the unified communications stack that the projector is one node of. Use the AV-IP-vs-HDBaseT and Rack Explorer tools for those.
What this preset deliberately does not solve
- Ambient light tolerance is the dominant lumens driver — measure lux at the screen plane.
- 16:10 aspect ratio assumes a Mac/Windows boardroom; check the source devices.
- Service life of laser engines is a TCO consideration, not a throw consideration.
How this preset differs from its siblings
The home-theatre preset configures a dark-room cinema scenario — 16:9 film content, low-lumens projector acceptable, screen gain considerations dominate. This preset is the opposite: a daily-use business environment that is never fully blacked out, where lumens (not throw ratio) is the real specification driver, and where 16:10 (not 16:9) is the source-content reality. Different brief, different projector class, different TCO calculation.
