You need to revise your question, is this uniform size you are talking about from the observer perspective?
The angular size or apparent size of the sun is how big the sun is in our visual field. The sun's angular size is about 0.5°. The size isn't really the issue so much as the fact that it doesn't significantly change. It changes slightly over the course of a year due to the Earth following an elliptical orbit around the sun. However, at any given time of year it is exactly the same everywhere on Earth and over the course of a day at any given location.
There are 2 ways in which this information conflicts with a flat earth model
1) The sun grows and shrinks in the Flat Earth model, but not in observed reality.
2) The sun never goes below the horizon in the Flat Earth model, but it does in observed reality.
Buildings disappear all together because they get too far away from our 'angular perspective' but the sun and moon, at 3,000 miles away, and 32 miles wide is visible at a great distance and is of considerable size, yet an airplane at 8 miles up is the size of a pin head. I am not understanding the selective use of the 'law of perspective
