Our Wall Covering Calculator is designed for precise estimation of the materials needed for wall finishing. With its help, you can determine the exact quantity of tiles, the required amount of paint, the number of wallpaper rolls, and the volume of plaster required to cover your walls. This tool aids in calculating materials based on specific room dimensions, helping you avoid excess costs and unnecessary waste.

To begin, enter the dimensions of the room, including the length, width, and height of the walls. Also, specify the number and sizes of windows and door openings so they can be excluded from the total wall area, ensuring a more accurate calculation of the finishing surface.

When estimating tiles, provide the dimensions of a single tile. The calculator will automatically determine how many tiles are necessary to cover the specified area, taking into account potential losses during cutting and installation.

For paint calculations, enter the coverage rate per square meter as indicated on the manufacturer's packaging. The calculator then computes the total amount of paint required to cover all the walls, considering any window or door openings.

When calculating wallpaper needs, input the length and width of a wallpaper roll. The tool will determine the number of rolls required to cover the wall area, rounding up to ensure any potential waste is accounted for.

To compute the volume of plaster, specify the desired thickness of the application layer. The calculator then determines the total volume of plaster needed, allowing you to prepare the correct amount of material in advance.

Our calculator is designed for convenience and efficiency: input fields for window openings are highlighted in blue, and those for door openings are highlighted in pink, simplifying the process and reducing the likelihood of errors.

By using our Wall Covering Calculator, you can quickly and accurately estimate the materials required for tile, paint, wallpaper, and plaster, optimize your budget, and ensure a high-quality wall finishing project.
