How to Get Different Image Sizes in Dalle-3

DALL·E’s latest Dalle-3 AI image generation model has captivated the world with its ability to create stunning images from simple text prompts. However, out-of-the-box Dalle-3 generates fixed 1024×1024 pixel square images. While this standard size suits many use cases, Dalle’s default 1:1 aspect ratio isn’t suitable for all image needs. Thankfully, Dalle-3 supports multiple image dimensions and provides tools to easily alter image sizes and aspect ratios. This guide covers all the methods to get different image sizes from Dalle-3 by OpenAI.

Dalle-3’s Default Image Size and Aspect Ratio

All Dalle-3 images generated through the API or ChatGPT integration measure 1024 pixels wide by 1024 pixels tall by default, with a 1:1 or square aspect ratio. This pixel size delivers ample resolution for digital use and moderate print sizes.

However, square images don’t always meet needs. For example, rectangular shapes better suit portrait orientation photos or widescreen landscape drawings. Changing Dalle-3’s default 1024×1024 size or 1:1 ratio requires utilizing ancillary tools like outpainting, uncropping, or external editing.

Key Limitations of 1024×1024 Images

While handy for general purposes, some major limitations arise from Dalle’s fixed square 1024×1024 dimensions:

  • Constrains image types: Landscape, portrait, banner, and social media templates need rectangular ratios.
  • Insufficient print resolution: Quality suffers from printing above 8′′x10′′. Approximating a magazine cover or large format print requires more pixels.
  • Incompatible dimensions: Posters, digital ads, mobile screens, video formats, etc. all use defined aspect ratios.
  • Fixed crop boundaries: No ability to adjust the center point or focal area relative to the overall scene.

Thankfully multiple techniques exist to alter image size and ratios to suit any situation when Dalle-3’s out-of-box 1024×1024 pixel images don’t meet needs.

Special Sauce: Controlling Image Sizes in DALL-E 3 Before Image Generation

DALL-E 3 introduces helpful features enabling users improved control over tailoring image dimensions and frames directly in initial generation prompts.

In particular, DALL-E 3 empowers specifying target orientations and aspect ratios upfront instead of adjusting square images through additional outpainting or uncropping. This gives more flexibility in matching bespoke dimensions or content needs from the very first DALL-E 3 rendering rather than necessitating hand correction or modifications after the fact.

DALL-E 3 Size Templates Available

At present ChatGPT integration of DALL-E 3 supports invoking these three distinct size options adapted to typical use orientations:

  1. Square (1024×1024): Default 1:1 dimensions ideal for social media icons, hero images, graphics, and prints up to 8″x10″.
  2. Landscape (1792×1024): Rectangular 16:9 widescreen shape perfect for panoramic landscape drawings, device wallpapers, or horizontal banner website templates.
  3. Portrait (1024×1792): Vertical 4:5 portrait configuration well-suited for full-length subject photography, elongated artwork, or other prominent height-over-width compositions.

Use Dalle-3 Outpainting to Change Aspect Ratio

Dalle-3’s innovative outpainting feature essentially expands an initial image beyond its borders to alter shape and size. Outpainting shifts aspect ratios from square to rectangular while increasing overall pixel dimensions and scene details. It’s one of the simplest ways to get different image sizes from Dalle-3 models.

Outpainting Process to Adjust Aspect Ratio

Follow these key steps to use outpainting for resizing Dalle images:

  1. Generate a starting 1024×1024 image with the desired core scene
  2. Upload the image into the Dalle-3 editor
  3. Position additional generation frame alongside an existing image
  4. Enter prompt text describing new outpainted content
  5. Dalle-3 adds to the original image based on the prompt to alter the aspect ratio

Essentially outpainting stitches new image areas to an existing picture to change its frame. Key tips for effective outpainting include:

  • Overlap generation frame slightly over original image edge
  • Use prompts clearly segregated from the initial image content
  • Accept the best of 4 outpaint suggestions to finish the altered image

Outpainting Effectively Resizes Dalle-3 Images

Applying outpainting effectively resizes images by increasing either height or width. For instance, extending a 1024×1024 image sideways makes a 2048×1024 picture for a 2:1 landscape rectangle. Outpainting downwards creates 1024×2048 portrait images instead.

This example demonstrates outpainting Dalle-3 images to change the aspect ratio from 1:1 to 16:9 widescreen:

Outpainting constitutes one of the most flexible ways to overcome Dalle-3’s limited default 1024×1024 pixel size and square image constraint. The main drawback is each outpainting iteration incurs extra credit charges.

Alter Aspect Ratio with Dalle-3 Uncropping

Dalle-3 uncropping provides another method to adjust AI image sizes, shapes, and ratios. It’s called “uncropping” since it starts by unframing and zooming out a scene to add new areas previously cropped. Dalle-3 then fills uncropped space based on the prompt.

Typical Dalle-3 Uncropping Workflow

Follow this standard uncropping process to effectively expand Dalle-3 images beyond 1024×1024:

  1. Begin with 1024×1024 Dalle-3 generated image
  2. Insert the image into a larger canvas in an editing program
  3. Save an unframed file showing an image surrounded by empty space
  4. Upload externally edited file back into Dalle-3
  5. Dalle-3 will generate additional content to fill canvas
  6. Crop the final image to the desired dimensions and ratios

Uncropping successfully alters image ratios and sizes. It also costs less than outpainting since only the initial external editing and final cropping steps consume credits.

Uncropping Example Resizing to 16:9

This uncropping example converts a Dalle square image to 16:9 widescreen:

Like outpainting, uncropping enables adjusting Dalle-3’s constrained default 1024 pixel size and set aspect ratios to any needed shapes or dimensions.

Additional Dalle-3 Image Size and Ratio Considerations

Beyond outpainting and uncropping to alter sizes and dimensions, other notable Dalle-3 image factors exist:

Native Dalle-3 Resolutions

Dalle-3 currently supports generating:

  • 1024×1024: Default square image size
  • 1024×1792: Rectangular vertical portrait shape
  • 1792×1024: Rectangular landscape orientation

No Built-In Image Reduction Methods

No native Dalle-3 tools lower resolutions under 1024 pixels. However, the API enables creating:

  • 512×512
  • 256×256

Smaller sizes for bandwidth savings or thumbnails.

Enhanced Details Require Larger Images

Increasing Dalle-3 image pixel sizes augments rendering compute time and credits burned, but also improves generated image quality and fine details by allowing the model more space to construct intricate textures not possible at 1024×1024.

Rectangular Shapes Increase Edits Flexibility

Adjusting the aspect ratio from Dalle’s inherent 1:1 square opens more options to crop final images to highlight key focal points not possible within a fixed 1024×1024 frame. More space to work enables better image composition.

Dalle-3 APIs Support Dimensions Input

Dalle-3 API calls accept explicit pixel width and height arguments to override defaults and generate prescribed sizes directly. However, this often secretaries additional credits compared to post-generation editing.

In summary, Dalle-3’s 1024×1024 pixel square images certainly don’t fit all use cases. But simple workarounds like outpainting and uncropping make modifying sizes and aspect ratios easy. Take advantage of these methods to match custom dimensions required for displaying content across blogs, presentations, documents, devices, prints, and more.

Handy Tips For Changing Dalle-3 Image Shapes and Dimensions

Follow these handy tips to smoothly modify Dalle-3’s default square 1024×1024 generation size for other applications:
