# Specifying Aspect Ratios

By simply adding the appropriate `aspect ratio` for your intended use, you can create a more complete prompt.

For an Instagram post, a **1:1** (Square) ratio works well, while a **7:4** (Landscape) ratio is ideal for a blog header image.

If you're creating an image for a smartphone wallpaper or a poster, a **4:7** (Portrait) ratio is suitable.

For example, let's modify the Santa Claus prompt we used, adding the style along with the aspect ratio and intended use like this:

```markdown
Santa Claus riding a sleigh pulled by two reindeer in the night sky, in an oil painting style, with an aspect ratio of 4:7 as a Portrait image
```

Please note that the DALLE-3 model only supports 1:1 (Square), 7:4 (Landscape), and 4:7 (Portrait) aspect ratios.

The DALLE-3 model supports only three aspect ratios for image generation: 1:1, 7:4, and 4:7. You may use 1:1 for social media posts, 7:4 for blog headers, and 4:7 for posters.
