Calculate the amount of timber needed to build a house: volume, pieces, and cost.
Enter house dimensions and timber parameters, then click Calculate.
Calculating the required amount of timber for building a house is essential for accurate budgeting and material planning. The theoretical calculation is based on the total wall area: multiply the perimeter of the house by the wall height to get the gross wall area, subtract the areas of windows and doors to get the net area, then multiply by the timber width to get the volume. The formula is V = (P · H — A_windows — A_doors) · t, where P is the perimeter, H is the wall height, and t is the timber thickness. The number of pieces is found by dividing the total volume by the volume of one timber piece (length × width × height). It is recommended to add a 10–15% reserve to account for waste, cuts, and potential defects. This calculator is essential for builders, architects, and homeowners planning a timber house project.
