What is the difference between a volleyball for indoor courts and a volleyball for outdoor or sand courts?

Question

I recently started playing sand volleyball and the balls seem to be very different. Any one know what makes a volleyball an indoor ball vs. an outdoor ball?

Answer 1

The beach volley-ball is softer (lower internal pressure) and slightly bigger than an indoor volleyball.

Answer 2

outdoor balls have in general always been heavier, thicker ... I assume it's due to, playing outside, the ball needs to be able to handle the elements better. sand, grass, rocks etc etc.

Answer 3

outdoor ball is heavier and has less air pressure.  This is so the wind can't push the ball as much and to slow the ball down a touch due to only having two players a side.  Indoor ball is clearly the opposite.

Answer 4

i think an outdoor ball has to be a little bit heavier than an indoor ball so that it doesn't float or move much in the wind or outdoor weather.

Answer 5

Ball dimension is the same.  

Weigh is different.

Internal air pressure is lower for beach ball.
