Standard Joint Sizes of Glass Bongs

Acrylic water pipes usually have metal downpipes with only one size, so it's no problem to exchange the bowls. It's a little more difficult with glass bongs. Not each bowl fits each downpipe or diffuser. There are different sizes but the Manufacturers stick to common industrial standards for the joint sizes.

Common Joint Sizes for glass bongs are

12.5mm (very rare)
14.5mm
18.8mm
29.2mm (rare)

Usually, yet not always, smaller pipes have a joint size of 14.5mm and bigger bongs have a 18.8mm joint size.
