Projector Tools

Free online projector tools for planning and calibrating your setup: throw-distance, screen-size and lumens calculators, plus focus, keystone, gamma and color test patterns you can project straight from the browser.

📽️

Projector Test Patterns

Focus, color, geometry, contrast and convergence patterns. Control from your phone via QR code.

📐

Projector Throw Distance Calculator

Find the right placement for any projector. Works with raw throw ratio — no model lookup required.

🖼️

Projector Screen Size Calculator

Diagonal to width × height for any aspect ratio, plus optimal viewing distance per THX (36°) and SMPTE (30°).

🎯

Projector Focus Test

Five focus patterns to lock perfect sharpness on any projector. Fullscreen, keyboard and swipe nav.

🔲

Projector Keystone Alignment Grid

Adjustable fullscreen grid with edge markers for keystone, lens shift and geometry calibration.

💡

Projector Lumens Calculator

Get the recommended ANSI lumens for your screen size, room lighting and content type (SDR/HDR).

🌡️

Projector Color Temperature Test

Eight calibration points from warm 2700K tungsten through D65 daylight to 9300K cool. Fullscreen with keyboard nav.

📊

Projector Gamma Test

Side-by-side gamma reference patterns for 1.8, 2.2, 2.4 and BT.1886. The 1px-stripe half should blend with the reference grey at correct gamma.

👁️

Viewing Distance Calculator

Resolution-aware calculator. Tells you minimum, optimal and maximum seating distance for your screen — 4K lets you sit closer than 1080p.

🎬

AV Sync (Lip Sync) Test

Synchronised flash + click. Record on your phone, count frames between flash and audio peak, multiply by 16.7 ms.

⏱️

Presentation Countdown

Pick a duration, press Start. Huge digits fill the projector — readable from anywhere in the room. Beeps at countdown < 10 s and at zero.

🔊

Speaker Positioning Guide

Top-down diagrams for each system. Shows correct angles per Dolby/THX standards: front 30°, surround 90–110°, rear 150°, height ±45° elevation.

🔥

Projector Warmup / Run-In

Auto-cycles colour fields, gradients and motion patterns for the duration you set. Helps equalise panels on a new LCD or DLP projector.

💰

Projector TCO Calculator

Total cost of ownership over the period you choose: purchase + replacement lamps + electricity. Reveals whether a lamp or laser projector saves money for your usage.

📸

Projector Camera Analyzer

Point your phone camera at the projected image. Get live RGB histogram, white balance check, 9-zone uniformity score, and clipping detection.

🥽

Projector 3D Test

Five test patterns for 3D projector calibration: anaglyph, L/R separation, depth, crosstalk, convergence. Wear your 3D glasses (red-cyan or active shutter).

🧩

Projector Edge Blending

Soft-edge gradient overlap pattern for multi-projector setups. Adjustable overlap percentage, gamma-correct ramp, four edges.

🌟

Bias Light Calculator

Calculates LED strip length, recommended brightness, and the right colour temperature for the bias light behind your screen.

🎨

DIY Screen Paint Calculator

Specifies the right grey paint (Behr or Sherwin-Williams) for your room lighting and calculates how much paint, primer and pearl additive you need.

🌈

Projector HDR Test

PQ-encoded test patterns for HDR projectors: nit-step ramp, clipping check at 800–1500 nits, near-black detail, peak-white reference, Rec.709 vs Rec.2020 gamut comparison.

📢

Projector Noise Meter

Microphone-based sound-level meter with A-weighting. Place phone 1 m from projector, press Start, get peak/avg/min readings.
