How It Works

Four simple steps to transform any image into a scaled floor plan

1. Upload Image

Import your floor plan image - scanned blueprint, photo, or digital file

2. Select Two Points

Click on two points with known distance for precision calibration

3. Enter Measurement

Input the real-world distance between your selected points

4. Start Drawing

Begin tracing with perfect scale and automatic grid alignment
