| Quarter (1/4 oz) | 0.25 oz | 7 g |
| Half ounce (1/2 oz) | 0.5 oz | 14 g |
| Ounce (1 oz) | 1 oz | 28.35 g |

Eighth vs. Quarter vs. Ounce: Cannabis Measurements Compared
Understanding where an eighth fits helps you gauge how much to buy. Here's the full scale of common cannabis weights.
| Weight | Ounces | Grams | Typical Use |
|---|---|---|---|
| Gram | 0.035 oz | 1 g | Small purchase, a few bowls or one joint |
| Eighth (1/8 oz) | 0.125 oz | 3.5 g | Most popular single purchase; about 5–7 joints |
| Quarter (1/4 oz) | 0.25 oz | 7 g | Two eighths; good for regular users |
| Half ounce (1/2 oz) | 0.5 oz | 14 g | Four eighths; better value per gram |
| Ounce | 1 oz | 28.35 g | Eight eighths; best value, often for frequent users |
As you can see, an eighth is smaller than a quarter but larger than a gram. Two eighths make a quarter, and four eighths make a half ounce. Eight eighths make a full ounce.

How Many Joints Does an Eighth Make?
An eighth (3.5 grams) typically yields about 5–7 joints if you roll standard-sized joints (0.5–0.7 g each). If you use a bowl, you might get 7–10 bowls, depending on how much you pack.
| Method | Amount per use | Approx. uses per eighth |
|---|---|---|
| Joint (standard) | 0.5–0.7 g | 5–7 joints |
| Bowl (pipe) | 0.3–0.5 g | 7–10 bowls |
| Vaporizer | 0.2–0.3 g | 10–15 sessions |
So an eighth is a good amount for a casual user to last a week or more. If you're a heavier smoker, you might go through it in a day or two.

What Does an Eighth of Weed Look Like?
An eighth of flower is roughly the size of a small handful—about 3–4 grams of buds. Depending on density, that could be 2–4 medium-sized buds or a mix of smaller ones. It fits easily in the palm of your hand.
Visually, it's about the size of a walnut or a small lemon. If you're buying pre-ground, it looks like a small bag of herbs. At Cannavine, our budtenders can show you exactly what an eighth looks like before you buy.
