You probably want to begin by playing someone who is at about your skill level or a little better, and preferably someone who isn't aggressively competitive. This way, you can have fun learning how to play. You can play one-on-one, or you can play with two teams of two, which is known as doubles. And you want someone who has regulation ping pong balls, paddles, and a table if you don't have access to any!
If your hand-eye coordination is more on par with a three-legged, blind dog, you might want to start practicing against a wall and getting familiar with how the ball and paddle work together. It's best on a table against the wall, for the record.
You want to play or practice with balls that are orange or white and 40 mm in size. The table should be 2.74 meters (9.0 ft) long, 1.525 meters (5.0 ft) wide, and 0.76 meters (2.5 ft) high.[1] Ping pong paddles don't have a regulation size, actually. Small paddles are hard to use successfully and bigger paddles weigh too much and are cumbersome. But they must be made of wood and rubber and competition paddles must have two colors.
