Okay, safety is the number one reason. But depth also affects the look of the dive. When a diver enters cleanly, you barely see a splash. That "rip entry" happens because the diver punches a tiny hole in the water’s surface, and the deep water absorbs the energy.
The pressure from the deep pool actually helps keep the diver’s body straight during entry. It’s like the water is giving them a gentle, firm hug from all sides. If the pool were shallow, the water would splash everywhere, making it look messy and unfocused. Judges hate a big splash.

What About Pools That Aren't Olympic?
You might be wondering: do non-Olympic pools use this same depth? Nope. Most high school or college diving pools are four meters deep. It’s a tiny difference, but for an elite athlete, it changes everything.
They say the true test is the 10-meter platform. Only the deepest pools are trusted for that height. It’s like the difference between a sturdy trampoline and a flimsy mattress—one gives you a great bounce, the other gives you a sore back. The depth makes the performance possible.
