From the PHB:
"High Jump. When you make a high jump, you leap into the air a number of feet equal to 3 + your Strength modifier if you move at least 10 feet on foot immediately before the jump. When you make a standing high jump, you can jump only half that distance. ... In some circumstances, your DM might allow you to make a Strength (Athletics) check to jump higher than you normally can."
So 20 Str can do a Standing high jump of (3+5)/2=4 vertical feet. What would it look like to do even more than that (in some circumstances)?
The Korean game Show Physical:100 has just showed me. Enjoy.
