How to draw a floor plan from your own measurements

1. Make a measurement sketch before opening the editor

Sketch the room outline on paper and label each wall in a consistent direction around the room. Measure inside wall lengths, then note the distance from a corner to each door or window and the width of that opening. Mark fixed features that could affect furniture placement.

Keep all measurements in one unit while recording them. The room-geometry dialog uses metres: 425 centimetres becomes 4.25 metres, and 900 millimetres becomes 0.90 metres. Furniture dimensions in the editor use millimetres, so a 90-centimetre-wide item is entered as 900. Follow the unit beside each field. Label uncertain values so you know which dimensions need another visit with the tape measure.

2. Build the room boundaries and connections

Draw the main rooms and resize them to match the sketch. Work on their relative positions before furnishing. For an apartment, follow the route from the entrance through the shared spaces and into each bedroom to check that the digital arrangement matches the real one.

1. Create the main room shapes

   Start with the simplest room and use it as a reference for adjoining spaces. Enter the dimensions you recorded instead of judging scale by appearance.

2. Add walls and openings

   Place doors and windows using their measured offsets from the corners. Check which spaces each door connects.

3. Resolve mismatches early

   If rooms do not line up, recheck the measurements and what each one includes. Avoid changing a reliable dimension merely to make the picture look tidy.

3. Place furniture and test the layout

Add the largest furniture first, such as the bed, sofa and table. Drag and rotate each piece while keeping the doors, windows and walking routes visible. Compare furniture dimensions with the actual pieces you own or are considering.

A piece can fit inside a room outline and still be inconvenient to use. Look at the space needed to pull out a dining chair, stand beside a bed or reach storage. Adjust the layout around these activities before adding decorative details or changing materials.

4. Cross-check the plan and save a useful copy

Compare at least two independent dimensions with your measurement notes. Then inspect the same design in 2D, 3D and the real scene view. The plan view helps reveal misplaced boundaries; 3D helps you understand the arrangement of walls and furniture.

Export a PNG when you want a picture to compare or discuss. Export JSON to keep the plan data. Browser drafts and signed-in cloud projects support ongoing work, but a separate export is useful when preserving a particular version of a layout.
