well once you have calculated the internal volume of the enclosure and have selected the decired tuning freq that you want to use.

you go to this link. and using that formula you calculate the port length.

remember to calcualte the port displacement, so you can add that to the total enclosure volume before you build the enclosure,

PS: this subject has been talked about on this forum allot of times, so if youre in a hurry to find the answere you can search and find the answere that youre looking for.
