Understanding Ultra Short Throw Projectors
An ultra short throw projectors (UST) is a revolutionary device that projects large images from just inches away from the wall or screen. Unlike traditional projectors that require several feet of distance, UST models can display a 100-inch image from as little as 4-24 inches away. This makes them perfect for small rooms, apartments, or spaces where ceiling mounting isn’t practical.
These projectors use advanced optical technology to achieve this short projection distance. Many models feature laser or LED light sources, which offer longer lifespans and better color accuracy than traditional lamp-based projectors.
Key Advantages of Ultra Short Throw Projectors
- Space Saving Design: Fits in rooms where traditional projectors would be impractical
- No Shadow Interference: You can walk in front of the projector without casting shadows
- High Quality Images: Many models offer 4K resolution with HDR support
- Easy Installation: Simply place on a stand or entertainment center – no ceiling mounting required
- Eye Protection: Reduced risk of looking directly into the light source
Factors to Consider When Choosing a UST Projector
1. Room Size and Layout
The first thing to consider is your room dimensions. Measure the distance from where you plan to place the projector to your screen or wall. Most UST projectors need just 4-24 inches to project a 100-inch image, but requirements vary by model.

For small rooms (under 12 feet deep), look for projectors with a throw ratio of 0.25:1 or less. Larger spaces can accommodate models with slightly longer throw distances.
2. Brightness Requirements
Projector brightness is measured in lumens. For UST projectors
- 2,000-2,500 lumens works well in dark rooms
- 3,000+ lumens is better for rooms with ambient light
- 4,000+ lumens is ideal for spaces with lots of windows

3. Resolution Options
Most UST projectors come in either 1080p or 4K resolution:
- 4K models provide the sharpest image but cost more
- 1080p models are more affordable and still look great
If you’re using the projector for movies or gaming, 4K is worth the investment. For casual viewing, 1080p may be sufficient.
Top Ultra Short Throw Projector Recommendations
Premium Pick: Epson ultra short throw projector – EpiqVision Ultra
This high-end model delivers stunning 4K HDR images with 3,600 lumens brightness. It can project up to 150 inches from just 4.7 feet away.

Selecting the Right Screen
UST projectors work best with special ambient light rejecting (ALR) screens. These screens:
- Improve contrast in rooms with light
- Reduce hotspots and glare
- Maintain image quality at wide viewing angles
Screen size should match your projector’s capabilities – most UST projectors work well with 100-120 inch screens.
Final Thoughts
Choosing the right ultra short throw projector depends on your space, budget, and viewing needs. Premium 4K models deliver the best experience, but excellent 1080p options are available at lower prices. Pair your projector with a quality ALR screen for optimal performance.
With their space-saving design and impressive image quality, UST projectors offer a compelling alternative to traditional TVs and projectors. Whether for movies, gaming, or presentations, there’s a model perfect for your needs.
