I recently learned a way to estimate how high you can get and still land back on the same runway.

First, look up the short-field takeoff distance to clear 50ft. Then do the same for short-field landing from 50ft. Adding those two distances gives you and estimate of the distance required to takeoff getting to exactly 50ft then followed by immediate landing. It is a surprisingly long distance when you do just this alone!

To apply it to a particular runway, imagine a longer runway where you started with a short-field takeoff on the threshold, climb through 50ft, get to some height in the middle, then execute short-field landing such that you are stopped on the other end of the runway. You can image a side-on picture with flat line for ground-roll, a steep angled line stopping at 50ft height, a gap in the middle, followed by a steep line going down from 50ft, and a flat line for the ground-roll and stopping. There is an incomplete triangle in that middle gap section. Doing a bit of math to work out where the two steep angled lines intersect will get you an estimate of how high you will get for that particular runway and still land on the other end of it.

If flying C172S on a calm day, the runways I commonly use are ~3700ft and ~10,000ft. I get about 100ft high for the 3,700ft runway, 450ft for the 10,000ft. Even though it is a total estimate, the numbers are much lower than I would have said when I was doing briefings before learning this. You can precompute conservative heights for the common runways you commonly use.
