How to make a floor plan

PRACTICAL GUIDE · UPDATED 20 OCTOBER 2026

To make a useful floor plan with AI, start with measurements and fixed features, choose image generation or measured geometry, then revise one version at a time. FloorPlanBot can help you create a visual concept, edit a reference image or work with a supported rectangular apartment layout. Choose the output you actually need before spending credits.

This guide is maintained by Julian Tao, FloorPlanBot’s founder. The examples below are sample instructions, not customer plans or guarantees of model accuracy.

Which tool do I need: a floor plan, room photo redesign or measured layout?

Choose by your starting material and intended output. A picture of a room, a top-down floor plan and a coordinate-based layout solve different problems.

Google sign-in is required for AI generation and private saved work. New accounts receive 3 free credits; each delivered AI image or revision uses 1 credit, subject to capacity limits. Local template tools and converters do not require sign-in. Supported measured-layout creation and edits do not consume image credits; text interpretation has a separate daily allowance. See current pricing before buying more use.

What should I include in a floor plan prompt?

Include the footprint, units, room count, fixed elements, room relationships and label language. Put essential constraints before visual style. If a dimension is unknown, say so; do not replace it with a guessed measurement.

1. Footprint: width and depth, and whether they describe the outside of the building or inside usable space.
2. Rooms: bedrooms, bathrooms and any separate work or storage space.
3. Fixed elements: entrance, windows, stairs, columns and services in an existing property.
4. Relationships: what should connect, what needs privacy, and which features are flexible.
5. Output: a top-down concept, a style image or measured geometry within the supported scope.
6. Labels: choose the language in the tool’s label-language setting. English is the default.

Example: a three-bedroom house concept

Create a top-down concept for a single-storey home with a 10 m wide by 15 m deep exterior footprint. Include three bedrooms, one shared bathroom and an open kitchen/living area. Place the entrance on the east side. Keep bedrooms separate from the main living area. Use English room labels.

This brief is for exploring an arrangement. An AI image may not meet every dimension. For numerical control in a supported rectangular apartment configuration, enter the requirements in the measured planner, review its interpretation and inspect the checks before saving.

Example: a small bedroom with a work area

Plan a 3 m by 4 m bedroom. Keep a 1.4 m by 2 m bed and a 1.2 m by 0.6 m desk. The door is at the southwest corner and the window is on the north wall. Show a route from the door to the bed and desk. Do not block the window with tall storage.

Use the room planning tool for this visual comparison. Check the real bed, chair movement and storage openings separately before moving furniture.

How do I change one detail without generating a completely different plan?

Continue from the chosen image and ask for one focused change. The image workflow carries the current image and earlier requirements into the next revision. Use “Start a new plan instead” only when you want a separate concept.

Keep the current room count, exterior outline, entrance and windows. Change only the living-room sofa upholstery from gray to blue. Keep the sofa’s position and size.

For an isolated visual change, open the editor and draw a rectangular selection. The selected-area workflow retains the original pixels outside that rectangle when composing the output. A full-image edit has no equivalent pixel lock. Watch the boundary where an object crosses the selection, and compare the result with the version you intended to preserve.

A delivered AI revision uses 1 credit, even when you decide to revise it again. Technical failure without a delivered image does not deduct credits. The measured planner has a separate versioned workflow for supported geometry changes; a text annotation on an image does not move a wall.

Should I upload a room photo, sketch or PDF?

Use a room photo for appearance, and a top-down drawing for arrangement. FloorPlanBot’s image tools accept PNG or JPEG up to 8 MB. Export a PDF page or CAD view to one of those formats first; direct PDF, DWG and DXF import are not supported.

For a room photo, show the floor, doors and windows in a level, well-lit view. Keep furniture you want to retain visible and avoid stretched panoramas. For a sketch, make labels and wall lines readable. Retain the original drawing because converting it to an image removes editable objects and layers.

Restyle this room using warm wood and cream textiles. Keep the existing sofa, floor, door and both windows. Change only the curtains, rug and loose decor. Do not add windows, built-ins or new flooring.

Preservation requests guide a full-room image; they do not guarantee that every item stays unchanged. If an earlier result has already removed an important piece, return to the original reference before revising. Upload only material you have permission to use and remove sensitive details; AI submissions are processed by an external provider as described in our privacy policy.

How do I check scale and choose PNG, PDF, SVG or DXF?

Calibrate from a reliable known distance, then check a second distance. A room’s area alone does not reveal its width and depth. A “standard” door or sofa is not a dependable measurement of your particular property.

In the image editor, review or trace linework and calibrate it against a known length. For example, if a verified 4 m wall spans 800 image pixels, the scale is 0.005 m per pixel. Check another measured wall before exporting. A stretched or perspective image can have inconsistent scale, so one calibration cannot make every part accurate. Use the unit converters to keep measurements in one system.

• PNG: a convenient image for reviewing and sharing.
• PDF: a document for sharing or printing; the format alone does not establish print scale or CAD editability.
• DXF from templates or images: schematic template lines or reviewed, calibrated image linework. It is not automatic architectural object recognition.
• Measured-layout SVG and DXF: exports from the supported layout’s coordinates; PNG and PDF can also be exported from that layout. Check units in the receiving application.

A 3D-style rendering is still an image. It does not become an editable OBJ, IFC or navigable model by changing the download format.

What should I check before sharing the plan?

Compare the result with your written brief and measured source, not just its appearance. Use this checklist to prepare the next conversation:

• Count bedrooms, bathrooms and the spaces you asked for.
• Check the exterior outline, entry side, stairs, doors and windows against the source.
• Verify units, wall measurements and what the stated floor area includes.
• Compare furniture footprints, door swings and usable movement space with real dimensions.
• Check room-label spelling and the selected language.
• Save the preferred version, original reference and a short list of unresolved questions.

FloorPlanBot’s concepts and supported geometry checks are not construction certification. Give your designer or other responsible professional the measurements, fixed conditions and preferred arrangement for project-specific review.
