AeroRatio: Airbrush Paint Calc

Stop guessing. Start spraying perfectly. AeroRatio is the first airbrush dilution calculator designed specifically for miniature painters, scale modelers, and hobby enthusiasts. It calculates the exact paint-to-thinner ratio based on your specific setup — brand, nozzle size, and air pressure. ▸ WHY AERORATIO? Every paint brand has different viscosity. Every color within a brand can differ. Your 0.2mm nozzle needs thinner paint than a 0.5mm. Higher PSI means less thinning. AeroRatio does the math so you don't waste expensive paint. ▸ ALL FEATURES INCLUDED — NO PAYWALL • 15+ paint brands: Citadel (Base, Layer, Air, Contrast), Vallejo (Model Color, Game Color, Model Air), AK Interactive (3rd Gen), Scale75, Tamiya, ProAcryl, Army Painter, Reaper, Monument, Kimera, Mr. Color & more • Output in DROPS — the format you actually use at your hobby desk • Visual consistency meter (thick → skim milk → water) • PSI slider (10–40 psi) with real-time ratio updates • Nozzle presets (0.15mm to 0.5mm) • Unlimited recipe journal with photos • Custom paint profiles — add your own brands with viscosity coefficients • Advanced thinner type selector (brand thinner, IPA, water, lacquer) • Humidity & temperature correction • Multi-layer recipes (primer → base → highlight → varnish) • PDF export for print-ready recipe cards • Quick troubleshooting cards (tip dry, spiderwebbing, orange peel) ▸ DESIGNED FOR YOUR WORKSHOP • Dark mode optimized — easy on the eyes at your paint station • Widget support — check your last recipe from your home screen • Haptic feedback on sliders for precise adjustments • No AI, no cloud, no account — just physics-based calculations • 100% offline — works in your hobby room with no signal ▸ BUILT BY A PAINTER, FOR PAINTERS AeroRatio was born from frustration with wasted paint, clogged nozzles, and hours of googling "Citadel Base thinning ratio for 0.3mm". We tested ratios across dozens of brands to build a viscosity database that actually works. One price. Everything included. No ads. No subscription. No paywall. No data collection.
