Short answer: for one or two people who smoke daily, a medium grinder (about 2.5 inches across) is the right size. Go small (under 2 inches) if it lives in your pocket, and go large (3 inches and up) if you roll in batches or grind for a group.
Grinder sizing is weirdly confusing. Brands say "small" and mean anything from a bottle cap to a hockey puck. So here's the honest guide, with real measurements, from people who have spent an unreasonable amount of time holding grinders.
| Grinder | Diameter | Weight | Best for | Price |
|---|---|---|---|---|
| 4 Piece Small | 1.855 in | 4 oz | Pocket, travel, a bowl at a time | $59.99 |
| 2 Piece Medium | 2.47 in | 5 oz | Quick daily grinding, no kief | $39.99 |
| 4 Piece Medium | 2.47 in | 7 oz | The everyday grinder for 1 to 2 people | $79.99 |
| 2 Piece Large | 3.225 in | 9 oz | Big batches, no kief | $49.99 |
| 4 Piece Large Flat Top | 3.225 in | — | Groups and bulk rolling | $89.99 |
| 4 Piece Large w/ Paper Holder | 3.225 in | 9 oz | Rolling station in one tool | $99.99 |
For context, a hockey puck is 3 inches across. Our large is a touch bigger than a puck. It is not subtle. It is glorious.
If the answer is "my pocket," go small. A 4 Piece Small still catches kief and won't print a suspicious circle through your jeans. If it lives on the coffee table, go medium or large. Bigger grinders are easier to hold and turn, and they don't wander off.
Overstuffing is the number one way people wreck their grind (we wrote a whole rant about it). If you routinely grind enough for a couple of joints or a full vape session, a small grinder means multiple loads. A medium handles a normal session in one go. A large handles the whole crew.
Rollers should look hard at the 4 Piece Large with paper holder and ashtray. The lid holds a pack of 1 1/4 papers and has a built-in rolling dish. You'll stop hunting for papers. Your friends will stop "borrowing" yours. Probably.
This one gets skipped and shouldn't. Bigger diameter means more leverage, which means less grip strength to turn it. If you deal with arthritis or hand pain, a medium or large Phoenician with the notched grip and short-twist quick lock is far easier than a tiny threaded grinder. Easy grip for folks with weaker hands was baked into our design from day one.

"Bigger grinders grind finer." Nope. Grind texture comes from tooth design and how you use your weed grinder, not diameter.
"A small grinder is fine if I just grind twice." Sure, if you love doing chores. Two loads is fine occasionally. Every day it gets old fast.
"Large grinders are only for heavy smokers." Large weed grinders are for anyone who likes things easy. Easier grip, fewer loads, more kief capacity.
A medium. It's forgiving, easy to hold, and handles a normal session in one load.
Anything under about 2 inches. Our 4 Piece Small is 1.855 inches across.
Not if it lives at home. You just won't fill it every time, and that's fine. Load what you need.
Yes. Every 2 piece and 4 piece carries our limited lifetime warranty on the teeth, lock couplings and screen brace.

A 2 piece weed grinder is a lid and a bowl, nothing else. No screen to clog, no chamber to empty, and a fluffier grind because the flower stays in the teeth instead of dropping through holes. Phoenician 2 piece grinders use the same arced cutter blades, threadless quick lock and aerospace-grade 6061-T6 aluminum as the PRO 4 piece, with a notched grip groove around the body, and they carry the same limited lifetime warranty.
People who roll or pack right away and do not want to collect kief, people who want the fastest clean possible, and anyone who prefers a lighter grinder. If you want to save trichomes, choose a 4 piece grinder with a kief catcher instead.
Medium: 2.47 inch diameter, 1.14 inch tall, 5 oz. The everyday size. $39.99.
Large: 3.225 inch diameter, 1.14 inch tall, 9 oz. For bigger batches and shared sessions. $49.99. See all large weed grinders.
