फॉर्मूला और गणना की विधि

Calculates total paint volume required by determining net wall surface area (perimeter × height minus door and window cutouts) divided by manufacturer coverage spread rates.

मानक गणितीय अंकन
Liters = [(Gross Wall Area − Openings Area) · Number of Coats] / Spread Rate (m²/L)

कदम-दर-कदम गणना का उदाहरण

4m × 3.5m Room with 2.8m Ceiling (2 Coats)

Estimating paint for a room with 1 door (1.8m²) and 2 windows (2.4m² total) using 10 m²/L emulsion.

1
Gross Wall Area
2 × (4.0 + 3.5) × 2.8 = 2 × 7.5 × 2.8 = 42.0 m²
Perimeter × Height
2
Openings Deduction
1.8 m² (Door) + 2.4 m² (Windows) = 4.2 m²
Unpainted cutouts
3
Net Area to Paint
42.0 − 4.2 = 37.8 m²
Net wall area
4
Total Paint for 2 Coats
(37.8 m² × 2 coats) / 10 m²/L = 75.6 / 10 = 7.56 Litres
Total volume needed
निष्कर्ष: You will need approximately 7.6 Liters of paint, which can be purchased as one 4L can and four 1L cans (or two 4L cans).
विशेषज्ञ विश्लेषण और मार्गदर्शिका

Primer and Surface Porosity Factors

Freshly plastered drywall or masonry walls absorb paint voraciously. Applying a dedicated acrylic wall primer seals the surface and prevents high-grade emulsion from soaking unevenly into the substrate.

Dark paint colors transitioning to light shades may require 3 coats, whereas refreshing an existing similar shade typically requires only 2.

अक्सर पूछे जाने वाले प्रश्न (FAQ)

Wall Paint Quantity & Can Requirement कैलकुलेटर से जुड़े अक्सर पूछे जाने वाले प्रश्न

How much area does 1 liter of wall paint cover?

Standard interior emulsion covers approximately 10 to 12 square meters (100 to 130 square feet) per liter for a single coat on primed walls.

Should I include the ceiling?

If painting the ceiling, add (Length × Width) to your total surface area.
