The pick: 10 to 12 inches with a beaker base
For a first bong, buy a 10 to 12 inch beaker with one chamber, a 14mm or 18mm downstem, and a bowl you can hold. That size covers the widest range of people. It clears with a normal breath, it sits steady on a table, and it costs less than the fancy glass you will want later anyway. If you only read one line here, that is the line.

Why that size and not something else
A bong does two jobs. It cools smoke and it filters some harsh material through water. Both jobs scale with size, but not in a straight line. Past about 14 inches, extra volume stops helping and starts hurting. You have more air to pull before smoke arrives, and more smoke left in the tube when you stop. Under about 8 inches, the smoke barely touches water before it hits you, so it stays hot.
I look at three things when someone asks me to pick: how hard it is to clear, how annoying it is to clean, and whether it survives a tip-over. A 10 to 12 inch beaker does well on all three.
- Clear: one chamber means one pull, no stacking
- Clean: straight walls, no hidden percs, a 10 minute iso soak handles it
- Stable: wide beaker base, hard to knock over
- Cheap to replace: thick 5mm glass runs about $40 to $90
Option 2: an 8 to 9 inch mini beaker
Pick this if you smoke alone, in small amounts, or you need to store it in a drawer. Small bongs hit quick and you can clear the whole thing in one go. The trade is heat. Smoke spends less time in contact with water, so hits land warmer. Get one with an ice pinch if you can. A couple of cubes makes a real difference.
Option 3: a 14 to 16 inch beaker for two or more people
Bigger tubes shine when several people share. More volume means each person gets a full hit without reheating the bowl. The downside is drag. You have to move more air, which gets tiring if your lungs are not used to it. Skip this as a first buy unless you know you will almost always have company.
What to skip on a first bong
Recyclers, triple-perc towers, and anything with a name longer than the tube. Every percolator adds drag and adds a place for resin to hide. A $200 multi-chamber piece can be harder to live with than a $50 beaker, and cleaning it takes three times as long. Buy simple now. Buy weird later, once you know what you like.
The convenience angle
Here is what changed in the last few years. Beginners stopped asking which bong hits hardest and started asking which one fits their routine. That question pushes the answer toward smaller, simpler glass. A bong you can rinse in the sink in two minutes gets used. A bong that needs a full teardown sits in a closet. Size and simplicity turn out to be the same decision more often than not.
Bottom line
Buy a 10 to 12 inch beaker with one chamber and 5mm glass. Add an ice pinch and an ash catcher later if you want them. If you smoke alone in small doses, drop to 8 or 9 inches. If you host often, go to 14. Everyone else: the middle is the answer.
