Tips for an accurate result
Irregular rooms are easier to estimate by splitting them into simple rectangles and adding the parts together.
Add a 10% buffer to material estimates (paint, flooring) to cover cuts, waste, and touch-ups.
Measure twice — an error in a room dimension carries through every downstream calculation.
Keep your measurements and calculations in one place (a notes app or spreadsheet) — home projects often need the same numbers again later.
