- TL;DR Summary
- How can I find the size an object will appear (Such as on a photo with a ruler) When it is in the distance by knowing how far it is and it's size when closer

This is a weird question that I'm not quite sure how to phrase so I'll do my best.

Reason for the question: I'm trying to learn perspective in art but guides and tutorials aren't helping so I thought of using geometry.

Scenario/question: I'm looking to have a formula I could use to see how far an object would appear in the distance compared to a closer "origin" point. For example how wide a road is 100 meters away base on it's size up close "X" or how tall a building's wall is 10 meters away when it's other end is visible at 0 meters at a height of "Y"

Does this make sense? Sorry I don't know which prefix to use for this I don't know how advanced this question is so I went with undergrad to be safe since I don't think that was covered in high school 10 years ago
