Square Footage Calculator
Measure rooms and plan whole-box flooring purchases
Square Footage Calculator is a free browser tool for DIY room measurement and flooring purchase planning. Enter feet and inches or metric dimensions, calculate common shapes and combine rooms with added or subtracted sections. Carry the measured area into a flooring plan that separates waste allowance, whole-box rounding, spare boxes and optional costs. Copy or print results without an account. Measurements remain in the current tab, so save a copy before refreshing. The tool provides planning estimates; product instructions and site measurements still determine an actual order.
