How the estimate works
To measure a room's area in square meters (m²), start by measuring the length and width of the room using a tape measure. Ensure measurements are taken from wall to wall at the widest points for accuracy. Multiply the length by the width to get the total area in m². For irregularly shaped rooms, divide them into simpler shapes like rectangles or triangles, calculate each section's area separately, then sum these areas.
How to reduce the cost
- Use a laser measure for precision.
- Measure twice to avoid mistakes.
- Include any alcoves or protrusions in your calculations.
FAQ
For most purposes, measuring to the nearest centimeter is sufficient. However, for construction projects, professional accuracy may require millimeters.
Yes, many apps can help you measure rooms accurately using your phone's camera and sensors. Ensure the app provides reliable measurements.
Measure around any obstacles or include them as part of the measurement area. Divide complex shapes into simpler geometric forms for easier calculations.
