What makes a good AI image prompt?

A good AI image prompt gives the model clear visual direction without overwhelming it with unnecessary detail. The best prompts usually combine a specific subject with supporting elements like style, lighting, mood, setting, or composition.

For example, instead of writing “a city at night,” a stronger prompt would be “a rainy Tokyo street at night, neon reflections, cinematic lighting, realistic photography style.”

The second prompt gives the AI clearer information about atmosphere, visual style, and composition, leading to more consistent and intentional results.

If you’re struggling to make your prompts specific enough, Quillbot’s AI Image Prompt Generator can help you brainstorm descriptive details, visual styles, and composition ideas you might not think to include on your own.

What size is a hero image?: A full-screen hero image is typically sized at 1280 × 720 pixels with a 16:9 aspect ratio, ensuring clarity on most screens. However, depending on your site’s design and target devices, you might opt for larger dimensions, such as 1600 × 900 pixels or 1920 × 1080 pixels, to maintain image quality on high-resolution displays.

Always test your image across various devices to ensure it loads quickly and appears sharp. You can use Quillbot’s AI Image Generator to create high-quality visuals that fit your design, then adjust them as needed.
Should AI image prompts be written in full sentences?: No, AI image prompts do not need to be written in full sentences. Image generators don’t interpret language like conversational chatbots; they respond better to keywords and short descriptive phrases.

Full sentences often add non-essential framing words like “a picture of” or “with a,” which can dilute the key visual instructions.

For more consistent results, use structured, comma-separated phrases that focus only on the visual elements you want. For example, “woman in a café reading a book, soft natural light, cozy atmosphere, cinematic style.”

If you’re unsure how to structure your prompt, Quillbot’s AI Image Prompt Generator can help you quickly brainstorm more detailed starting points.
