12 Portal Prompts That Turn a Simple Object Into a Doorway

Most portal images fail for the same reason. The opening looks pasted on. The world inside doesn't match the light outside, so your eye reads it as two pictures stuck together instead of one doorway.

A portal is any opening that shows a different world on the other side. Sunglasses. A keyhole. A frame standing in a field. A phone screen. The object matters less than you think. What matters is that the opening feels real and the world behind it feels complete.

Below are twelve portals, each with the exact Midjourney prompt that made it. Use them as written, swap the brackets for your own subject, or pull them apart and build your own. They're a framework, not a script.
