Model Paint Usage Calculator
Perfect your painting projects with precise paint estimates
Ventilation Notice: Always work in a well-ventilated area when using paints, thinners, and solvents. Use appropriate protective equipment as recommended by the paint manufacturer.
Tip: For best results, measure an existing painted model to calibrate your estimates.

Paint Saving Tips:
- Use a wet palette to extend paint working time
- Thin paints appropriately for each application
Professional Model Painting Techniques
Paint Application
- Prime with light gray for neutral base
- Apply thin coats (2-3 thin layers better than 1 thick)
- Let each layer dry completely before next application
- Use brush sizes appropriate for each area
Paint Conservation
- Store paints upside down to prevent separation
- Add flow improver to extend paint life on palette
- Use dropper bottles for precise dispensing
- Keep paint lids clean for proper sealing
"Professional model painters typically use 20-30% less paint than beginners by mastering thinning ratios and application techniques."
Paint Coverage Guide by Model Type
Military Vehicles
Base coats typically require 12-15cm² per ml. Camouflage patterns increase paint usage by 15-20%. Matte finishes generally need slightly more paint than gloss. Don't forget to account for tools/equipment that may be added.
Aircraft
Smooth surfaces average 15-18cm² per ml. Lighter colors may require extra coats for opacity. Canopy framing and small details can significantly increase paint needs - add 10-15% to estimates for detailed cockpits.
Miniatures/Figures
28mm figures average 8-12cm² per ml due to complex surfaces. Layering and highlighting can double paint consumption. Metallics often cover less area than standard paints - reduce coverage estimates by 20% for metallic paints.
Pro Tip: Create a paint log for your first model of each type. Record actual paint used to calibrate future estimates more accurately.
Model Paint Calculator FAQs
How accurate are these paint estimates?
Our calculator provides professional-grade estimates based on surface area and typical coverage rates. Actual usage varies by: paint brand (consistency differs), brush technique, thinning ratio, and color (lighter tones often need more coats). For precise estimates, test your specific paint on scrap material first.
Should I account for primer in my calculations?
Primer isn't included in these estimates as it's typically applied differently (spray cans/airbrush). As a rule of thumb: one standard spray can (400ml) covers approximately 50-70 1/35 scale vehicles or 100-150 miniatures when applied properly.
How does thinning affect paint usage?
Thinning increases coverage area but requires more coats. A 1:1 paint-to-thinner ratio typically: Increases coverage by 30-40% but requires 2 coats instead of 1. The calculator automatically adjusts for this when you select your application method and number of coats.
What's the average paint bottle lifespan?
For 17ml bottles: 5-8 vehicles (1/35 scale) | 15-25 miniatures (28mm) | 3-5 aircraft (1/48 scale). These averages assume proper thinning and efficient application. Unthinned paint covers less area but may leave brush marks.
How can I reduce paint waste?
1) Use a wet palette 2) Mix small batches for custom colors 3) Store unused mixed paints in airtight containers 4) Clean brushes properly to avoid paint contamination 5) Plan your color sequence from light to dark 6) Use leftover paints for terrain/textures.
