    It's a mini-bong but it has an 18 size bowl

    should be 18mm.. double check with a metric ruler

    You can either measure it, as said above (the diameter at the top of the joint, not including the glass walls of the joint.) or just take the bowl and see if it fits where the downstem goes...if the bowl is 18 and it fits then the hole is 18.

    you can always bring it into a local headshop (make sure it's clean) and they can prob size it for you if you're really not sure
