When setting up a projector for the ultimate home theater or a portable gaming rig, knowing the exact dimensions of the unit is as important as choosing the right lens. Precise measurements help you plan space, mount the device securely, and calculate the optimal screen size and viewing distance. This guide pulls together the most reliable dimension data for popular BenQ models and explains how to apply it in real‑world setups.
Why Accurate Size Matters in Your Projector Setup
Even a few inches of difference in a projector’s footprint can shift your entire installation. An oversized unit may outgrow your cabinet or clash with existing furniture, while a compact model might require a different mounting strategy to avoid heat buildup. For hobbyists who often repurpose spaces or build custom rigs, accurate dimensional knowledge saves time and prevents costly redesigns.
Key Measurements That Every Hobbyist Should Know
BenQ’s LU9715 and PU9730 offer a clear example of how dimension data is presented in official drawings and product guides. Below is a breakdown of the most critical measurements and how they impact your build.
- Overall Length: 27.7 in (70.4 cm) for the LU9715 vs. 25.2 in (64 cm) for the PU9730. The longer model requires a deeper cabinet or a larger mounting bracket.
- Overall Height: 13.4 in (34.1 cm) for the LU9715 and 12.5 in (31.8 cm) for the PU9730. Height affects vertical clearance, especially under ceilings or above shelves.
- Overall Width: 9.7 in (24.6 cm) for the LU9715 and 9.1 in (23.1 cm) for the PU9730. A narrower footprint can be advantageous in tight rooms.
- Depth of Lens Assembly: 5.8 in (14.7 cm) for the LU9715; 5.2 in (13.2 cm) for the PU9730. This determines how far the projector can sit from the screen while maintaining focus.
Applying the Data: From Drawing to Real‑World Installation
- Choose the Right Cabinet – Use the overall height and width to select a cabinet that provides enough clearance for ventilation. A cabinet that is too shallow will trap heat, shortening the projector’s lifespan.
- Mounting Strategy – For a wall‑mounted setup, the depth of the lens assembly dictates the minimum distance from the wall to the screen. A 5.8‑inch lens depth on the LU9715 means a slightly larger projection distance to achieve the same image size compared to the PU9730.
- Ventilation Planning – Place the projector at least 12 inches away from adjacent electronics. The larger the unit, the higher the airflow requirement, so align vents with the projector’s intake and exhaust points.
- Screen Size Calculation – Knowing the lens depth allows you to use the projector’s throw ratio to calculate screen width at your desired distance. For the LU9715’s 5.8‑inch lens depth, a 100‑inch screen at 12 ft works well; the PU9730 can achieve the same size at 11.5 ft.
Comparing Models: Which Size Fits Your Setup?
The LU9715’s slightly larger footprint offers a higher resolution (1920 × 1080) and better ambient light rejection, but it also demands more space. Hobbyists working in small apartments or studios may prefer the PU9730 for its compactness without sacrificing core performance. When space constraints are a priority, the PU9730’s 12.5‑inch height and 5.2‑inch lens depth make it a lighter, more adaptable choice.
Implications for Future Projects
Accurate dimension knowledge is not just about fitting a projector into a room; it shapes the entire visual experience. A well‑planned layout ensures that the projector’s light reaches the screen evenly, reduces distortion, and keeps the device cool. For hobbyists who upgrade frequently, maintaining a catalog of each model’s dimensions keeps future swaps hassle‑free. When you know exactly how tall, wide, and deep each projector is, you can focus on lighting, sound, and seating arrangements without wrestling with spatial constraints.
By grounding your build in precise measurements, you turn a potential source of frustration into a streamlined, efficient process. Whether you’re mounting a projector on a wall or constructing a custom cabinet, the numbers in these official drawings guide you toward a setup that looks good, feels right, and performs at its best.
