Part 6: Platform Dimension Cheat Sheet

Prompt Refinement Tips

Good prompt structure:

[FORMAT] for [PURPOSE]. [HEADLINE/MAIN TEXT]. [DESCRIPTION/SUBTEXT].
[VISUAL STYLE]. [COLOR PREFERENCES]. [CTA IF APPLICABLE].

Before (vague):

"Make me a social media post about my product"

After (specific):

"Instagram feed post (1080x1080) announcing a new feature. Headline: 'Say goodbye to manual invoicing.' Subtitle: 'AutoBill handles it all — set up in 2 minutes.' Dark background, teal accent, minimal design. CTA button: 'Try free'."

The difference:

Specific prompts generate designs you can use with minimal editing. Vague prompts generate designs you spend 10 minutes fixing.
