A 2D Floor Plan App Built for Measured Accuracy
Draw walls that snap square, get room areas calculated as you go, and label every dimension without touching a calculator. This is the precise, print-ready side of floor planning — clean line work, real numbers, and ANSI-compliant gross living area on every plan.
No subscription required for 2D plans and 2D exports — pay per export credit. Trusted across 415,000+ projects.
What is a 2D floor plan app used for?
A 2D floor plan app is used to draw an accurate top-down layout of a space, showing walls, doors, windows, room labels, and measured dimensions to scale. AI Floor Plan Builder handles this in the browser with wall snapping that keeps corners square, automatic per-room square footage, and gross living area calculated to the ANSI Z765 standard — the numbers appraisers and agents are expected to report. Plans can be labeled, branded, and exported as clean print-ready files for listings, permits, disclosure packets, or contractor bids. Drawing 2D plans and taking 2D exports requires no subscription, and the same drawing converts to interactive 3D later with one click if you need it.
Everything the app does
Snapping that keeps walls square
Walls lock to right angles, existing endpoints, and a configurable grid, so corners close cleanly instead of drifting a few inches off true.
Automatic dimension lines
Wall lengths are measured and labeled for you in feet and inches. Adjust a wall and the dimension updates with it.
ANSI-compliant square footage
Per-room areas and gross living area are computed to the ANSI Z765 standard as you draw — no spreadsheet, no manual tallying.
Scaled grid and unit control
Work in imperial or metric on a grid you set, so the drawing stays properly to scale from the first wall onward.
Doors, windows, and swing arcs
Drop openings onto any wall and get correct swing direction and standard architectural symbols in the 2D view.
Room labels and area callouts
Name each room and display its area right on the plan, so anyone reading it can see what a space is and how big it is.
Print-ready 2D exports
Export clean, legible files sized for listing sheets, disclosure packets, permit submissions, and contractor bids.
Your logo and brand colors
Add branding to the plan itself so what you hand a client looks like your deliverable, not generic software output.
How it works
- 01
Set your scale and units
Pick imperial or metric and a grid size, so every wall you draw is measured correctly from the start.
- 02
Draw walls with snapping on
Trace the perimeter, then interior partitions. Snapping squares up corners and closes rooms automatically.
- 03
Add openings and labels
Place doors and windows, name each room, and turn on dimensions and area callouts.
- 04
Export or convert to 3D
Download a print-ready 2D file, or click once to turn the same plan into an interactive 3D model.

Frequently asked questions
Is the 2D floor plan app free to use?
Drawing 2D floor plans and taking 2D exports does not require a subscription, so you can produce a finished measured plan without a monthly commitment. Paid export credits, at roughly a dollar or less each, apply when you want 3D output and hosted interactive models.
Does it calculate square footage automatically?
Yes. Each room reports its own area and the plan totals gross living area using the ANSI Z765 standard, recalculating live as you move walls. That removes the manual tallying step that is the usual source of reported-area errors.
Can I draw plans that are accurate to scale?
You set your units and grid before drawing, and wall snapping keeps segments aligned to right angles and existing endpoints. Accuracy of the finished plan still depends on the real-world measurements you enter, so measure carefully on site.
Can I add dimensions to the printed plan?
Yes. Wall lengths are measured and labeled automatically, and you can display per-room area callouts alongside room names. Everything stays legible in export so the plan is usable on a listing sheet or in a bid packet.
Does it work in metric as well as feet and inches?
Both are supported. Choose imperial or metric when you set up the drawing, and dimensions, areas, and exports all follow that unit system.
Can I turn my 2D plan into 3D later?
Yes, and you do not redraw anything. The same 2D drawing extrudes into an interactive 3D model in one click whenever you want a walkthrough or a 3D marketing asset.
Is this suitable for appraisal work?
The app computes area using the ANSI Z765 method that appraisal reporting expects, and produces clean labeled plans with dimensions. As with any tool, the output is only as accurate as the field measurements you put in, so it supports your workflow rather than replacing on-site verification.
