How Much Is A Gram Of Weed: Visually Understanding Marijuana Quantities

If you ever plan on purchasing cannabis, you’re going to want to know, how much is a gram of weed visually? A scale is an obvious way to keep track. However, you won’t always have your own scale on you. So it’s good to be able to visually tell the difference between 1 gram of weed and an eighth.

Converting From Ounces To Grams

First, you’ll want to learn how to convert from grams to ounces. Unless you plan to only buy dimes and dub bags for the rest of your life. The names eighth, quarter and halves are all sizes in relation to a full ounce. These are the main conversion you’ll need to know when purchasing various quantities of cannabis:

  • Eighth: 3.5 grams
  • Quarter: 7 grams
  • Half: 14 grams
  • Ounce: 28 grams

What Does A Gram Of Weed Look Like?

Some nugs are loose and fluffy while others are compact and dense. As a result, two different size nugs might end up weighing the same.

To help you visually understand what a gram of weed looks like we got some nugs from Slo Grown Genetics that weren’t too dense or too fluffy to weigh out. Then we weighed the main quantities you’ll see for sale out at the Rosin Tech Products booth during the SoCal Cannabis Cup.

This is what a gram looks like.

Compare it to the pictures of an eighth, quarter, half ounce and ounce. It should look like enough weed to roll a joint that can be shared.


To help you understand the difference between 1 gram of weed and an eighth of an ounce. An eighth should be enough to smoke for a few sessions.

Here is a picture of an eighth of the same weed on the same scale for reference.


Quarters also referred to as a Q’s. Once you visually understand what a gram and eighth look like, you should be able to picture a quarter. A quarter ounce is twice the amount of weight of an eighth so it should look like twice as much.

Here is what a quarter of the same strain on the same scale looks like from overhead so you can see the bowl filling.

The half or a half ounce is the largest quantity of cannabis you’ll see for sale before an ounce.

Take a look at the half to get an understanding of what you should expect in comparison to other weights.


An ounce is 28 grams of weed. It will be easier to spot an ounce when you know what an eighth, quarter and half an ounce visually look like.

Here is what an ounce looks like on the same scale with more of the same nugs.

If you’re interested in understanding larger quantities start by learning how many ounces are in a pound.

Final Hit: How Much Is A Gram Of Weed?

Now that you’ve seen these various quantities of cannabis next to each other, you should have a decent understanding of how to guess marijuana quantities with nothing but your eyes. As we mentioned earlier, some strains have a fluffier appearance than others while others are dense and heavy despite their smaller size. Knowing how to visually tell the difference between each quantity is enough to make sure you’re not paying for a quarter and getting an eighth. However, you’ll need a scale to guarantee that you’re not being skimped in small amounts that are hard to pick up by eye.

Visually compare a gram of weed to eighths, quarters, halves and ounces to understand how to tell them apart just by looking.
