I had a bowl with 1 cracker in it for 3 weeks. Over the last 24 hours it now has 7 crackers. And people say my cracker bowl is not overpopulated...

Look. Raw numbers mean nothing. What is the sustainable population of this planet. 1 billion? 10 billion? 100 billion?

I have no idea. As tech improves, our impact per person could be lower. So perhaps the limit today is 5 billion... But in 20 years it could be 20 billion.

Ultimately though, we WILL run out of habitable space.

Assuming you do know we are currently only using 3% of the Earths land surface, what reasons are there that humans will run out of space?

Could live vertically, even above ocean if tech allows it (with instant transortation maybe.). Theoretically we have some good amount of room left.

At even midsize population density, I am pretty sure we have space for WAY over 100 billion people on this planet. Food production needs some more work, perhaps a bit of us eating lower on the food chain..
