So you bought a projector. Congrats, you’ve officially entered the world of cinematic bliss, giant screens, and arguing with your wall about being “too textured.” But before you start binge-watching in IMAX-at-home mode, there’s a slightly annoying (yet crucial) chapter of life you must pass: Projector Placement.

Don’t worry, we’ll make this painless. Let’s decode throw distance, angles, and screen size like you’re five… but a very intelligent five.

Throw Distance, AKA, “How Far Should This Thing Sit?”

Throw distance is simply how far your projector needs to be from your screen/wall for the picture to look right. Too close, and your movie turns into pixelated modern art. Too far, and you’ll be watching a dim version of life through sunglasses.

Types of Throw Distances

1. Standard Throw (3m+ away)
    Good for large rooms and for people who believe space is a “mindset.”
   
2. Short Throw (1–2m away)
    Ideal for bedrooms, cosy setups, or Bangalore apartments.
   
3. Ultra Short Throw (Right against the wall)
    These are the show-offs of the projector world. Expensive and compact, and they hate distance.

Why This Matters

Throw distance determines:

• Your screen size
  
• Brightness
  
• Whether you need to rearrange your entire living room like you’re auditioning for HGTV
  

The exact distance depends on your projector’s throw ratio, which looks scary but is actually just:

Distance ÷ Screen Width

Example: If the ratio is 1.5:1, for a 2 m wide screen, you need 3 m distance. Boom, math that actually matters in real life.

Angles, "Why Does My Actor Look Like He's Sliding Off the Screen?"

Projectors are drama queens about angles. Tilt it a little, and suddenly everything becomes a trapezoid.

This phenomenon is called keystoning, because your rectangle quietly transforms into a trapezoid, like it’s auditioning for Cirque du Soleil.

How to Avoid Keystoning

• Keep the projector centred horizontally
  
• Keep the projector level with the screen
  
• Adjust height, not tilt, if possible
  
  

Most projectors also offer:

• Vertical Keystone Correction
  
• Horizontal Keystone Correction
  
• Auto Keystone (for the lazy, i.e., most of us)
  

But a word of wisdom:
Digital correction is basically Photoshop for your image - helpful, but not perfect.
Hardware alignment is always cleaner.

Screen Size: Because Size DOES Matter

Unlike TVs, projectors are commitment-phobic about screen size, it depends on how far they sit and how dark your room is.

Rule of Thumb

• Standard viewing: 80–120 inches
  
• Home theatre flex mode: 120–150 inches
  
• “My landlord will kill me” mode: 150 inches+
  

Also, consider your seating distance:

• Too close = pores, pixels, and regrets
  
• Too far = “Wait, what did that subtitle say?”
  

A safe seating distance is usually 1.5–2x the screen diagonal.

Example: 100-inch screen → Sit 150–200 inches (3.8 m–5 m) away.

Conclusion: You’re Basically a Projection Engineer Now

Getting projector placement right isn’t rocket science; it’s more like IKEA furniture assembly:

• Read the numbers
  
• Don’t force it
  
• Blame the manual when stuck
  

Once you dial in your throw distance, angle, and screen size, the payoff is glorious: a giant, cinematic image that makes every friend ask, “Bro, how much did this cost?”

(Your choice to lie or not… we don’t judge.)
