Precision Layout, Powered by FLUX 3 Image
Position every element on your own terms with draggable boxes, a canvas shape you choose, and a single line of scene direction.
- Drag-and-Draw Box ControlMark out a region for each element you care about, then write down what should appear inside it.
- Any Ratio, One 0–1000 GridSwitch canvas shapes freely — because width and height both run 0 to 1000, your box coordinates never lose their meaning.
- A Single Prompt to Unify ItOne scene line pulls all of your described boxes into a coherent whole, just like the Le Festival du Soleil example.

Questions About the FLUX 3 Image Layout Tool
Straight answers on drawing boxes, choosing canvas ratios and writing prompts for FLUX 3 Image.
How do the boxes decide where each element lands?
Each box you draw marks out the region that its described element will occupy in the finished picture.
What is the 0–1000 grid actually for?
Whichever canvas shape you choose, both axes are measured from 0 to 1000, so every box position sits on the same consistent scale.
Should I pick a canvas ratio before drawing boxes?
Yes. Choose the ratio first — since both axes always run 0 to 1000, the same coordinates stay readable when you switch shapes.
Where does the scene prompt fit in?
It is the single line that binds your individual elements together, as with the Le Festival du Soleil example built from boxes plus a scene prompt.
Can I describe every box on its own?
Absolutely. Once a box is drawn, you write what belongs inside it, so each region carries its own content instruction.
Is a subscription or seat licence required?
Not at all. Pricing is pay as you go — no subscriptions, no seat fees — you are billed only for what you generate, and open-weights tiers let you run the models on your own hardware.
