Quick answer: For most people, a 30cm bong is the best all-rounder — big enough for smooth, cool hits, small enough to handle and store easily. Go for around 20cm if you want portability and discretion, and around 40cm if you have the space and want the coolest, smoothest draws.
Bong size guide: 20cm vs 30cm vs 40cm
| Size | Best for | The hit | Handling |
|---|---|---|---|
| ~20cm (mini) | Portability, discretion, beginners | Quick to clear, less lung power needed | Easiest to store and travel with |
| ~30cm (medium) | The all-rounder — most popular | Smooth and cool, still easy to clear | Comfortable to hold, fits most shelves |
| ~40cm (tall) | The coolest, smoothest hits | Biggest, coolest draws; needs a stronger pull | Needs space; least portable |
Around 20cm — small and discreet
A mini bong (around 20cm) is the easiest to live with. It needs less lung capacity to clear, tucks into a drawer, and travels well — which makes it a strong first bong. The trade-off is a smaller water chamber, so hits aren’t quite as cool as a taller piece.
Around 30cm — the sweet spot
A 30cm bong is where most people land, and it’s the size we build around at KIICK AS. It holds enough water for a genuinely smooth, cool draw, yet it’s still easy to hold, clean and store. If you’re unsure what size to get, this is the safe answer. Both the Inception Percolator and the Summer Slice are 30cm for exactly this reason.
Around 40cm — the coolest hits
A tall bong (around 40cm) gives smoke the most contact with water, so it cools the most before you inhale — the smoothest draw of the three. The catch: you need a bigger pull to clear it, more space to store it, and a bit more care not to knock it over. Better suited to experienced smokers with room to keep it. In the KIICK AS range that’s the Mighty Rasta — 40cm, with an ice catcher for an even colder draw.
Bottom line
Portability first → ~20cm. Best all-round balance → ~30cm. Smoothest possible hit → ~40cm. If in doubt, start at 30cm. Shop KIICK AS 30cm acrylic bongs →
