Our construction calculator is designed for accurate calculation of the materials needed for finishing a space. With its help, you can calculate the quantity of tiles, the mass of paint, the number of rolls of wallpaper, and the volume of plaster required for the job. The calculator will assist in determining the materials needed for specific room dimensions, avoiding excess costs and saving your time.

To start the calculation, enter the dimensions of the room: the length, width, and height of the walls. Also, specify the number and sizes of windows and door openings to exclude them from the total finishing area. This will provide more accurate results and prevent material overuse.

When calculating the number of tiles, you need to enter the dimensions of a single tile. The calculator will automatically determine how many tiles are needed to cover the specified area, taking into account potential losses during cutting and laying.

To calculate the mass of paint, specify the paint coverage per square meter, which is usually indicated on the manufacturer's packaging. The calculator will compute the total mass of paint required for painting all walls, considering the openings.

When calculating the amount of wallpaper, enter the length and width of a wallpaper roll. The calculator will determine how many rolls are needed to cover the walls, rounding the result up to the nearest whole number to account for potential waste.

To determine the volume of plaster, specify the thickness of the application layer. The calculator will calculate the total volume of the mixture needed for plastering the walls, allowing you to prepare the necessary amount of material in advance.

Our calculator is designed for convenience and efficiency in planning construction work. The input fields for window openings are highlighted in blue, while those for door openings are highlighted in pink, facilitating the form-filling process and minimizing the chance of errors.

By using our tool, you can quickly and accurately calculate the quantity of necessary materials, optimize your budget, and ensure high-quality finishing work.
