Use this construction calculation for preliminary quantity, geometry, material, load, or coverage planning when dimensions and units have been measured consistently.

Horizontal Meters (m)

Required number input.

Vertical Meters (m)

Required number input.

Straight string-line distance between two measured planar site-layout points; sag and terrain elevation are excluded. The tool evaluates the supplied inputs together and returns the named outputs below; it does not infer omitted operating conditions or change the units shown.^[1]

Length Meters (m)

The resulting length meters returned as a number.

• A quantity estimate or simplified engineering formula is not a building-code check, stamped design, manufacturer approval, or site inspection. Material properties, tolerances, waste, moisture, workmanship, loads, local conditions, and code requirements can change the result.
• Use finite inputs in the displayed units and preserve more precision than the final presentation requires. Independently verify safety-critical, financial, compliance, or production decisions.

Verify dimensions on site, use current product data and local code requirements, include an explicit waste or safety allowance where appropriate, and obtain qualified structural, electrical, plumbing, or geotechnical review when required.

• Theoretical Rafter Length

  Find the straight-line rafter length between eave and ridge from horizontal run and vertical rise; excludes overhang and cuts.

• Carpet Seam Length

  Sum measured lengths of carpet seams; count only joins, not room perimeter or wall edges.

• Concrete Volume

  Calculate rectangular concrete volume in cubic meters from length, width, and pour thickness measured in meters.
