Image Settings

What each setting in the Image app does and which models have it, including aspect ratios for Instagram, YouTube thumbnails, stories, banners and book covers.

Each model in the Image app shows only the settings it supports. The defaults work well, so change them only when you need to. Settings marked as being under Advanced settings sit in a collapsed row near the bottom of the panel; select it to open.

Each model shows only its own settings. Here, Ideogram 4.5 offers Low, Medium and High quality.

Aspect ratio and size

Aspect ratio sets the shape of the image. On some models a Resolution menu appears after you pick a ratio, with labels such as "1K (1024 × 1024)" or "2K (2048 × 2048)".

Model	Aspect ratios	Default
Auto	Auto, 1:1, 4:3, 3:4, 3:2, 2:3, 16:9, 9:16	Auto
Ideogram 4.5	Auto, or a ratio from the Square, Landscape and Portrait groups, then Resolution 1K or 2K	Auto
Ideogram 4.0	Auto, or 1:1, 5:4, 4:3, 3:2, 8:5, 16:9, 2:1, 12:5, 22:9, 23:9, 8:3, 3:1 and their portrait mirrors, then Resolution 1K or 2K	Auto
Ideogram 3.0	1:1, 4:5, 5:4, 3:4, 4:3, 2:3, 3:2, 10:16, 16:10, 9:16, 16:9, 1:2, 2:1, 1:3, 3:1. No Auto and no Resolution menu	1:1

On Ideogram 4.0, the widest ratios (12:5, 22:9, 23:9, 8:3 and their mirrors) come in 2K only. Ideogram 4.5 offers the same ratios, but 3:1 and 1:3 also come in 2K only.

Common shapes: 1:1 for profile pictures, logos and stickers; 4:5 for Instagram and Facebook feed posts; 9:16 for Instagram Stories, Reels, TikTok and YouTube Shorts; 16:9 for YouTube thumbnails and presentations; 2:3 for Pinterest pins, posters and book covers; 3:1 for banners and website headers.

The Transparent and partner models have their own lists; see Models.

Size on Ideogram 4.5 with reference images

When you attach reference images to Ideogram 4.5, a Size menu replaces Aspect ratio and Resolution:

• Auto: "Picks a size from your images and prompt."

• Source image size: "Keeps the first image's own width and height."

• Custom: enter Width and Height. Each side must be a multiple of 32 and at least 256 px. The image can't be more than 2048 × 2048 pixels in total or wider than 6:1.

Number of images

Choose Auto or 1 to 8 images per run. More images cost more credits, and the Generate button shows the total. Every image model has this setting, and Auto is the default. On the Auto model, your last choice is kept for next time.

What Auto gives you depends on the model:

• Auto model: 4 images, or 2 when you attach references

• Ideogram models and P-Image-Ideogram: 4

• GPT Image, Nano Banana and Z-Image: 1

Quality

Quality trades speed and cost against detail. The cost on the Generate button changes with your choice.

Model	Options	Default on paid plans
Ideogram 4.5	Very low, Low, Medium, High. Very low appears only when you attach reference images	High
Ideogram 4.0, 3.0 and both Transparent models	Turbo, Default, Quality	Default
GPT Image 2.5	Auto, Low, Medium, High	Auto
P-Image-Ideogram	Very Low, Low, Medium, High	Medium

On a free plan, Ideogram models start at the cheapest option: Turbo, or Low on Ideogram 4.5. Auto and the other partner models have no Quality setting.

Magic Prompt

Magic Prompt "Enhances your prompt to improve image variety and richness. It can also translate your prompt into English." It's an on/off toggle, and it starts on. Turn it off when you want the model to follow your exact words.

Magic Prompt appears on Ideogram 4.5, 4.0, 3.0 and 3.0 Transparent. On Ideogram 4.5 it hides when you attach reference images, because the prompt then works as an edit instruction. Ideogram 4.0 Transparent has Prompt upsampling (Auto, On or Off) under Advanced settings instead. Auto and the partner models have no Magic Prompt; P-Image-Ideogram has its own Prompt upsampling switch under Advanced settings.

Ideogram 4.5 and 4.0 also accept JSON prompts. See JSON Prompting.

Take the prompt Photo of cupcake and strawberries. Magic Prompt expanded it into a longer prompt that added frosting, sprinkles and a rustic, sunlit background:

Magic Prompt off.

Magic Prompt on.

Seed

The seed is the number a run starts from. Use the same prompt, model, settings and seed to get the same or a very close result. Change one word and keep the seed to try a small change while keeping most of the layout.

Find Seed under Advanced settings on every image model. The field shows "Random" when empty, which means each run gets a new seed.

Set a seed

1. Open Advanced settings.

2. Enter digits only in Seed, up to 2147483647.

To fill in a random seed instead, select the dice button (New random seed).

Switching models, or changing a key idea in the prompt (say, "photo" to "painting"), gives a different image even with the same seed.

Collection

Add to Collection saves every image from your next runs into a collection. Every image model has this setting, and no collection is picked by default.

Save new images to a collection

1. Select Add to Collection.

2. Choose a collection. The button then shows the collection's name.

To stop saving to it, select the x on the button.

There's no public/private setting in the Image app. On Plus, Pro, Team and Enterprise, new images stay private until you publish one. On the free plan and the legacy Basic plan, everything you generate is public. To publish an image:

1. Open the image.

2. Select More options.

3. Select Manage.

4. Select Publish to community.

Ideogram 3.0 settings

These settings appear only on Ideogram 3.0, under Advanced settings. Custom models built on Ideogram 3.0 have them too, except the Style menu.

Negative prompt

Negative prompt ("Things to avoid") lists what you don't want in the image. Separate items with commas, for example green, green candies. The field has its own Describe button.

No negative prompt.

Negative prompt: green, green color, green candies.

Your main prompt always wins. If you ask for a classical guitar, the model will draw strings, whatever the negative prompt says. It often works better to write a prompt that leaves the thing out. See Fix Common Problems.

Style

Three controls shape the look of an Ideogram 3.0 image.

Style sets the overall type:

• Auto (default): picks a style from your prompt

• General: fits most uses, including art and abstract work

• Realistic: lifelike photos with true colors, textures and light

• Design: clean, vector-like images such as logos and posters

Style preset opens Style presets: "Distinct, prescriptive aesthetics that define the image's look even with short prompts." Choose None or one of 62 presets.

Style reference images take up to 10 of your own images (JPEG, PNG or WebP, up to 25 MB each) and copy their look. Pick images that share a look and mood for a steady style, or mix different ones to see what the model blends. A gradient image among them pulls the colors toward it.

Presets and style reference images work only with the Auto or General style; with Realistic or Design you'll see "Available with the Auto or General style." You can use a preset or style references, not both: "Style references replace the style preset."

Apply a style preset

1. Choose Ideogram 3.0 in the Model picker.

2. Open Advanced settings.

3. Set Style to Auto or General.

4. Select Style preset to open Style presets.

5. Choose a preset.

Add style reference images

1. Choose Ideogram 3.0 in the Model picker.

2. Open Advanced settings.

3. Set Style to Auto or General.

4. Add up to 10 images in Style reference images.

For a preset or style references to come through clearly, turn Magic Prompt off and keep style words out of your prompt. Short prompts work best.

Color palette

Color palette steers the colors of the image. Treat it as a direction, not an exact color match; it works best alongside color words in your prompt.

Choose None, a preset (Ember, Fresh, Jungle, Magic, Melon, Mosaic, Pastel or Ultramarine) or Custom.

Custom palettes need a Plus, Pro, Team or Enterprise plan. On other plans the option shows as Custom (Plus) and can't be picked.

Use a custom palette

1. Choose Ideogram 3.0 in the Model picker.

2. Open Advanced settings.

3. Set Color palette to Custom. A Palette colors field appears.

4. Type up to 8 hex codes in Palette colors, separated by spaces, such as #FF5733 #0133FF #DE3357.

No palette.

Ultramarine.
