How to use it
- Enter the floor area in square feet.
- Specify the desired pour thickness in inches.
- Input the product coverage rating (sq ft per gallon at 1/8 in).
- Read the gallons result and round up for ordering.
Enter the square‑footage of the floor, the thickness you plan to pour, and the manufacturer's coverage rating (sq ft per gallon at 1/8 in). The calculator converts those inputs into the exact gallons of self‑leveler required, based on the constant that 1/8 in equals 0.125 in. Knowing the precise volume helps you order the right amount, avoid costly over‑orders, and keep the project on schedule. The result appears as a single gallon figure; you can round up to the nearest whole container for ordering. Use the example below to verify the math: 500 sq ft area, 0.25 in thickness, 400 sq ft/gal at 1/8 in gives 2.5 gal. If you have multiple rooms, repeat the calculation for each and sum the totals. The tool works for both residential remodels and commercial floor installations, ensuring you never run short mid‑pour. It also lets you compare different product coverages to pick the most cost‑effective option.

Case study
Mike, a DIY homeowner, entered 800 sq ft, 0.20 in thickness, and a 350 sq ft/gal rating. The calculator showed 4.6 gal; he ordered 5 gal and completed his garage floor without any leftover or a second delivery.
