How do I specify aspect ratios in Midjourney?

Add the aspect ratio parameter at the end of your prompt, such as `--ar 2:3` for a vertical poster, `--ar 3:4` for standard prints, or `--ar 1:1` for a square print.

What style prompts sell best on Etsy?

Minimalist botanicals, boho abstract watercolor, mid-century retro layouts, and moody vintage landscapes are highly popular.

Do I need to upscale Midjourney images before selling them?

Yes. Raw Midjourney files are too small for large prints. You must upscale them to 300 DPI to prevent pixelation.

Quick Answer

The best Midjourney prompts for printable wall art use specific style descriptors (like 'boho watercolor illustration', 'minimalist line art', or 'textured impasto oil painting') along with lighting tags and aspect ratio arguments (e.g. `--ar 2:3` or `--ar 3:4`). To sell these designs, you must upscale their resolution. ResizeFlow helps by upscaling the low-res exports to 300 DPI and formatting them into standard aspect ratios.
