Depends on the pool. When I worked at a swimming pool store, we saw all sizes, 10-15k gallons were commonplace.

Here's the easiest way to calculate it:

SHALLOW END DEPTH + DEEP END DEPTH + 2 = AVERAGE DEPTH

Rectangular Pools:

LENGTH X WIDTH X AVERAGE DEPTH X 7.5 = TOTAL GALLONS

Round Pools:

CIRCULAR DIAMETER X RADIUS X AVERAGE DEPTH X 5.9 = TOTAL GALLONS

Oval Pools:

FULL WIDTH X FULL LENGTH X AVERAGE DEPTH X 5.9 = TOTAL GALLONS
