Correct length for poker table legs?

[nolanfan34]

I seem to recall a couple of people mentioning that they cut the bottom off of the standard folding table legs to make it more of an "official" poker table height.

Is there a standard per se for this? I will agree that the two tables I built before feel a little higher than normal. How much should I cut off, like an inch or two of the leg?

Any thoughts would be appreciated.
