The problem in answering this question is what is an average pool? I will give the best answer I can. I will use an average size home pool of 16 ft by 32 ft by 5 ft depth.
The equation is Length X Width X Average Depth X 7.5 (for gallons in a cubic foot)
16 X 32 X 5 X 7.5 equals 19,200 gallons of water.
If we round up to 20,000 gallons we have an average amount for home pools. Between 20,000 and 30,000 gallons will cover most home pool installations for gallons of water. Some commercial pools are much larger and obviously contain much more water.

It depends on the size of the pool!
It depends on the size of the pool but 20,000 gallons is pretty common.
Assuming your pool is round about 800 gallons.
264 gallons is the max if it's a blow-up pool.
How many gallons of water for a 15'x30' swimming pool?
30,000 gallons.
That is approximately 146,252 gallons.
