    What are your recommendations on a short throw projector? Suggested lumens? Manufacturer? Other considerations? Thank you!

    Great question!

    Here are a few guidelines:
    • 0.5:1 or shorter throw if you want to consider front-projection without shadows.
    • 5,000 Lumens or greater, depending greatly on your lighting and control of light spread
    • Standard Definition or higher. You really don't need 4k for stage projection, because of the distance that the audience is from the surface. 
    • Many different manufacturers offer solutions for this. You'll save money with a fixed lens versus an interchangeable lens. Therefore the niche brands sometimes offer better deals. Larger brands usually have a single model at different brightness levels and secondary lens options to make a short throw. 
    If you have other questions, I'd be happy to help. Projectors and projections are what we do every day... and we understand schools! Remember that regardless of the hardware, you'll still need high-quality projection content (still or animated).

    Hope this helps!

    Here's a bit of essential info if you aren't familiar with projector specs:

    Throw ratios: The 0.5:1 listed above means "for every half-foot of distance, you'll get one foot of (diagonal) image." This is super-important when determining the size of image you want and how far away the projector will be, especially if the projector has limited or no ability to zoom larger/smaller. Most projector manufacturers have a googleable throw distance calculator to help with the math.

    Resolution: It's a measurement of how many pixels you have. These have names and numbers. The names can be a little misleading, so be sure to double-check the numbers. What was once "standard definition" is woefully small. Remember the web videos that opened in a tiny window, circa 1999? That's not standard anymore. I recommend a minimum of HD (1280 x 720). Here are the basics:

        Standard Definition - 640 x 480 (Aka "SD")
        720p - 1280 x 720 (Aka "HD" or "HD Ready")
        1280p - 1920 x 1080 (aka "Full HD")
        4k - 3840 x 2160 (aka "Ultra HD" or "2160p)

    Here is a very useful tool that allows the user to calculate throw, illumination and width of an image.  I found it very helpful in selecting our new laser projector for large venue application.
