It’s a tough answer because there’s usually more to a lot than just the size. Views? Privacy? Neighbors on all sides? But, for what it’s worth, we just bought a new house and the builder charged $35K on top of a $700K house in Carlsbad for a 7500 lot vs ours which is 5300. We both have ocean views, but we;re on opposite sides of the street, so its complicated. the other one has better ocean views now, until the next street down is built and he’ll loose the views except from 2nd floor. We have ocean out the front and side and canyons behind. Hope that was all of some help.
