Enter your Surface Shape, dimensions (Length and Width, or Diameter for circular floors), Coating Thickness, and Coverage Rate into the Epoxy Floor Calculator to find exactly how much epoxy you need — broken down into Gallons Needed, Total Ounces, and Volume, alongside your calculated Surface Area.

The amount depends on your floor's surface area and desired coating thickness. For a standard 1/8″ thick coating, you'll need approximately 3-4 oz of epoxy per square foot.
Most epoxy floor coatings are applied at 1/8″ (0.125 inches) thickness. This provides good durability and coverage while being cost-effective for residential and light commercial use.
For circular surfaces, measure the diameter and use the formula: Volume = π × radius² × thickness. Our calculator automatically handles this conversion when you select circular shape.
This calculator provides estimates based on standard coverage rates. Always order 10-15% extra epoxy to account for waste, spills, and variations in surface texture or porosity.
Standard coverage (3 oz/sq ft) works for most floors, heavy duty (4 oz/sq ft) provides thicker protection for high-traffic areas, and light coat (2 oz/sq ft) is suitable for decorative applications.
Properly applied epoxy floors can last 10-20 years in residential settings and 5-10 years in commercial environments, depending on traffic, maintenance, and environmental conditions.
Yes, this calculator works for any flat surface including countertops, tables, and art projects. Just enter the dimensions and desired thickness for accurate epoxy estimates.
