So, my country which feels big to me couldn't do it. This reinforces my belief that there are way too many of our species on this planet. Given that 2.1 or so is the replacement rate, a "hard" limit of two child per woman would be decent compromise as this would equate to somewhere around 1.7 taking into account women who don't want to /can't have children. In one generation, if there were no unintended consequences this would drop the population by 15%.

Sometime in the 2100s it would be half what it is today and my country could easily fit everyone!
