CALCULATOR
Linear Feet to Square Feet Calculator
Find rectangular strip area from length and width in feet. Example: Length: 2 ft, Width: 2 ft gives 4 ft². A width is required; length alone does not determine area. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only.
A width is required; length alone does not determine area. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area dimensions L×L give L².
Accepted inputs: Length: 0.001 to 1,000 ft; Width: 0.001 to 1,000 ft.
How the calculation works
square feet = linear feet × width feet
Worked example
With length 2 ft, width 2 ft, rectangular strip area from length and width in feet is 4 ft².
Assumptions and limits
A width is required; length alone does not determine area. Flat Euclidean shape; stated measurements in displayed units. No waste, thickness, structural suitability or curved-earth claim. Floating point rounding is display only. Derivation: Area dimensions L×L give L².
