Buying Guide for the Best Cheap Short Throw Projector
When choosing a cheap short-throw projector, it's important to focus on your intended use—whether that's for gaming, movies, presentations, or educational purposes. Short-throw projectors are designed to create large images from a short distance, which is great for small rooms or when you can't place the projector far from the screen. Understanding the main specifications will help you find one that matches your setup and expectations. Instead of chasing the highest numbers, think about your environment, what you want to watch, and how much flexibility you need for placement.Throw RatioThrow ratio describes how wide of an image the projector can create at a set distance from the screen. It's written as a number (like 0.5:1), which means the projector can produce a 1-meter wide image from just half a meter away. Lower throw ratios mean the projector can sit closer to the screen. If you have limited space or want to avoid people casting shadows while standing in front of the screen, look for a lower throw ratio—around 0.4:1 or 0.5:1. If you have a bit more space to work with, a ratio up to 1:1 is still manageable. Base your choice on how close you can place the projector to your wall or screen.
Brightness (Lumens)Brightness, measured in lumens, indicates how vivid the projector’s image will be, especially in rooms with ambient light. Low-brightness models (under 2000 lumens) are suitable for dark rooms, while medium-brightness (2000–3000 lumens) can handle some light, and high-brightness (over 3000 lumens) work better in well-lit spaces. Consider where you’ll use your projector—if you can control the lighting and make your room dark, lower brightness is fine, but if you cannot block all light, aim for something with more lumens.
ResolutionResolution is the amount of detail you’ll see in the projected image. Common resolutions for affordable projectors are SVGA (800x600), XGA (1024x768), 720p (1280x720), and Full HD 1080p (1920x1080). Lower resolutions show less detail and can look blurry for movies or detailed presentations, while higher resolutions provide a sharper picture. Choose a resolution based on what you plan to display: for movies and gaming, higher (at least 720p) is much better, while simple slideshows or basic documents can use lower.
Contrast RatioContrast ratio measures the difference between the brightest white and the darkest black in the picture. Higher numbers provide more depth and better-looking images, especially for movies with dark scenes. Typical cheap projectors have lower contrast, but try to select one with at least a 1000:1 ratio for more vibrant visuals. If you care about image quality for movies and entertainment, aim higher; for basic presentations, this is less critical.
Inputs and ConnectivityThe types of connections (HDMI, VGA, USB, etc.) a projector supports determine what you can plug in. HDMI is standard for modern devices like laptops, game consoles, and streaming sticks. Some budget projectors might have only older inputs like VGA or composite. Think about what you want to connect—look for at least one HDMI port, and make sure any unique devices you have (like USB drives or speakers) are supported.
Built-In AudioMany projectors come with built-in speakers, though sound quality varies. Small speakers might suit a quiet room or small gatherings, but for movie nights or larger rooms, you’ll get better sound quality by connecting external speakers. Consider if you need everything in one device or if you’re okay adding a sound system.
Keystone Correction and FocusKeystone correction lets you adjust the image shape if the projector isn’t perfectly straight with the screen, while focus controls let you sharpen the picture. Manual adjustments are common on budget models, which is fine if you don’t move the projector often. If you might relocate it regularly or can’t set it up perfectly straight, look for easy-to-use correction features.
