Default CO2 tanks and longevity question

I would really like to buy a 2.5lb tank instead of a 5lb for the sake
of space savings.

BUT, can someone tell me approx how long I could expect a 2.5lb tank
to last in a 10g and 20g (half as long I would guess).

I understand that it will vary depending on certain variables....I
just need a rough estimate, ie, 4-5-6 months?
