Pro Tips for 3:4 Portrait Images

Expert advice to get the best vertical image results

Compose for Vertical Space

Think vertically when creating 3:4 images. Mention subjects that naturally fill vertical space like standing figures, tall trees, towers, or stacked elements in your prompts.

Use Portrait-Friendly Keywords

Add keywords like 'portrait orientation', 'full body shot', 'vertical composition', or 'standing pose' to optimize the 3:4 image format.

Consider the Rule of Thirds

Place your main subject at one-third from the top or bottom. This classic composition rule works exceptionally well with vertical 3:4 images.

Leave Headroom for Text

If you plan to add text overlays to your 3:4 images, include 'space at top' in your prompt. This creates room for titles without covering important details.

Match Resolution to Use Case

For social media, 1K resolution works great. For print materials, use 2K or 4K resolution with your 3:4 aspect ratio.

Experiment with Art Styles

The 3:4 ratio works beautifully with various styles - try anime, realistic, watercolor, or digital art to see how each enhances your vertical compositions.
