Flux 2 Max Text to Image for Ultrawide and Tall Frames

Last verified: October 29, 2026

Flux 2 Max text-to-image generation is built for final assets: the hero image for a product page, a campaign key visual, the still you actually ship. It is the highest-quality FLUX.2 tier, and its photorealistic output is designed to blend in with real photography. On Vidofy you can frame that output as an ultrawide 21:9 for banners and cinematic headers, or as a tall 9:21 for phone screens and vertical placements.

You direct the result with words. Flux 2 Max is documented with the strongest prompt following in FLUX.2 and with faithful rendering of different styles, so a precise description of subject, light and look is what changes the image. It also has grounding search: it can build real-time information from the web into an image, such as yesterday's football scores, the current weather in a city or recent news events.

The form keeps only the choices that shape a finished still. You write the prompt, with Enhance Prompt available to expand a rough idea. Then you set the frame with Aspect Ratio and the output size with Resolution Quality. Lens, lighting, color and any text in the image all go into the prompt, so that is where most of your effort should go.

How Do You Write a Better Flux 2 Max Prompt?

Put the Subject First, Then Style and Context

Flux 2 Max pays more attention to what comes first, so use this order: main subject, key action, critical style, essential context, then secondary details. A medium-length prompt of about 30 to 80 words is usually ideal. Go shorter for quick concepts and style exploration, and longer only when a complex scene needs detailed specification. If an element keeps getting lost, move it earlier in the prompt rather than repeating it.

Name the Camera, Lens and Film Stock for Photoreal Results

For a photographic look, name real camera models, lenses and film stocks. A line like Shot on Fujifilm X-T5, 35mm f/1.4 gives more authentic results than just writing professional photo. Choose the reference for the look you want: a modern digital body for clean, high-dynamic-range sharpness, Kodak Portra 400 for natural grain and organic color, or an early digital camera with flash for a candid snapshot feel.

Use a JSON Prompt for Busy Scenes

Flux 2 Max accepts structured JSON prompts, a format recommended for production workflows. The base schema gives each subject its own description, position and action, alongside fields for scene, style, color palette, lighting, mood and background. The JSON is plain text, so it goes into the Prompt box like any other prompt. Keep one template for a series and change only the fields that should vary from image to image.

Making an Image With Flux 2 Max, Step by Step

Four steps from a written prompt to a downloaded image.

Write the Scene in the Prompt Box

Type your description into the "Prompt" box, which holds up to 5,000 characters. That is more room than most images need, so use it for concrete details rather than piles of adjectives. If you're starting from a rough idea, press "Enhance Prompt" under the box to see fuller versions of what you wrote. Your text only changes when you pick a suggestion, so you can read them and keep your own wording if it's closer to what you want.

Set Aspect Ratio and Resolution Quality

Pick the frame in "Aspect Ratio": 1:1 (the default), 4:3, 3:4, 16:9, 9:16, 3:2, 2:3, 21:9 or 9:21. Choose it for where the image will be used: 21:9 for website banners and cinematic headers, 9:21 for phone wallpapers and tall story placements, 1:1 or 4:3 for product grids. With 21:9 or 9:21, also say in the prompt how the scene should fill the frame, for example a subject on the left third with open land across the rest. That way the composition actually uses the extra width or height. Then pick "Resolution Quality": 1K (the default), 2K or 4K. Refine the prompt at 1K, then switch to 2K or 4K for the image you'll deliver or print, since that is the one that needs the pixels.

Click Generate

Click "Generate" once the prompt and both settings are set. Between runs, change one thing at a time, such as a lighting phrase, the frame or the resolution. That way you can tell which change caused which difference.

Download Your Image

Download the image once it's the one you want. View it at full size first: check any text in the image letter by letter and look closely at hands and product edges, because those are the details a client notices first.

Choosing Between Flux 2 Max and Other FLUX.2 Variants

How Flux 2 Max compares with the FLUX.2 variants positioned for production scale and real-time volume.

Criterion	Flux 2 Max	Alternatives	Best For
Final deliverables or production at scale	It is positioned for the highest quality and for final assets, the image that gets published or handed to a client.	FLUX.2 [pro] is positioned for production at scale.	Pick Flux 2 Max for hero images and finished campaign assets, and FLUX.2 [pro] when the job is producing images at scale.
Peak quality or real-time generation	It sits at the highest-quality end of the FLUX.2 range.	FLUX.2 [klein] sits at the other end of that range, built for sub-second inference and real-time, high-volume generation.	Choose FLUX.2 [klein] when you need real-time, high-volume generation, and Flux 2 Max when the image you keep has to be the highest-quality version of the idea.

Flux 2 Max is the FLUX.2 variant for the image you publish. FLUX.2 [pro] is positioned for production at scale and FLUX.2 [klein] for real-time, high-volume work.

Why Isn't Flux 2 Max Following My Prompt?

Fixes for the problems that come up most often in text-to-image runs.

I wrote 'no people' and 'no text', but they still show up.

Flux 2 Max does not support negative prompts, and its prompting guide says to describe what you want, not what you don't want. Rewrite each exclusion as the positive version of the scene: an empty beach at dawn instead of no people, a plain unmarked label instead of no text. Then run it again.

The text on my poster is misspelled or in the wrong place.

Flux 2 Max produces readable text when the text is described clearly. Make sure every word that must appear is inside quotation marks. Then say where it sits relative to other elements, and describe the lettering style and size, such as large headline, small body copy, bold industrial lettering or handwritten script. Get the headline right on its own first, then add secondary lines in later runs, so you have less text to check each time.

My brand color comes out a different shade.

Hex codes work best when each one is clearly tied to a specific object and introduced by the word color or hex. Vague instructions like use #FF0000 somewhere can give inconsistent results. Rewrite the line so every code belongs to a named element, for example a tote bag in color #2E4057, and generate again.

My full creative brief doesn't fit in the Prompt box.

The Prompt box has a character limit, and a pasted brief often includes client background the image doesn't need. Keep only what changes the picture: subject, action, style, lighting and composition. Cut repeated adjectives and project notes, then paste the shorter version and generate. The image comes only from the text you enter, so a tighter prompt loses nothing that would have shown up in the result.

Frequently Asked Questions

How many images does Flux 2 Max make per run?

Each run returns one image. To compare options, run the prompt again with a single change, such as a different lighting line or another frame from Aspect Ratio. That way each result shows you what the change did.

What makes one Flux 2 Max generation cost more than another?

The credit cost of a run is calculated from the options you choose and shown above the Generate button once you're signed in. It changes with Resolution Quality, so check the figure when you switch resolution. Getting suggestions from Enhance Prompt doesn't use credits.

Can I write Flux 2 Max prompts in languages other than English?

Yes. Flux 2 Max understands multiple languages. English prompts tend to give the most precise results, because most of the training data is in English. Prompting in the native language of the place you're depicting often gives more culturally authentic results, with local markets, architecture and atmosphere rendered more accurately. A practical split: use English for exact product and typography work, and the local language for culturally specific scenes.

How do I keep a character consistent across a comic strip or image series?

Write a separate prompt for each panel and repeat the same detailed character description every time: clothing, hair and any distinguishing features. Only the action, setting and dialogue should change. The official comic-strip example keeps the hero's description detailed and consistent across panels, and opens each prompt with the same style line. Keep Aspect Ratio the same for every panel too, so the panels line up when you assemble the strip.
