Weed Sizes Explained: Eighth, Quarter, Half & Ounce in Grams
Weed sizes can feel like a secret language: eighths, quarters, halves, zips. This guide translates every size into plain grams, shows what each one costs on the Pressure Deliveries menu in DC, and explains which size gets you the most flower for your money, including the free gift that comes with bigger orders.
Weed sizes at a glance
| Name | Grams | Fraction of an ounce | Our price | Price per gram |
|---|---|---|---|---|
| Eighth | 3.5g | 1/8 oz | $25 | about $7.14 |
| Quarter | 7g | 1/4 oz | $50 | about $7.14 |
| Half (half ounce) | 14g | 1/2 oz | $100 | about $7.14 |
| Ounce (an “O” or “zip”) | 28g | 1 oz | $175 | $6.25 |
Prices are from our current flower menu and can change. Every strain on the menu uses the same size ladder, so you can compare strains apples to apples.
How many grams in an eighth?
An eighth is 3.5 grams. Technically an eighth of an ounce is about 3.54 grams, but the industry rounds to 3.5g, and that’s what you’ll see on every menu.
Who it’s for: anyone trying a strain for the first time, or who likes to rotate. At $25, an eighth is the lowest-commitment way to find out whether a strain’s flavor and effects work for you.
How many grams in a quarter?
A quarter is 7 grams, or two eighths. It’s the sweet spot when you already know the strain you like and don’t want to reorder every few days.
On our menu a quarter is $50, the same price per gram as two eighths. The real advantage is fewer reorders, and on Mondays, 7 grams of flower unlocks the Monday Madness deal.
How many grams in a half ounce?
A half ounce is 14 grams. This is where buying bigger starts paying off at Pressure Deliveries: every order with 14 grams of flower or more earns a 2g free gift, any day of the week.
That turns a $100 half into 16 grams total, which works out to $6.25 per gram.
How many grams in an ounce?
An ounce is 28 grams (28.35g exactly, rounded down on menus). People also call it an “O” or a “zip.”
The ounce is the best value on the menu. At $175 it’s already the lowest price per gram, and 28 grams of flower earns a 3.5g free gift every day. That’s 31.5 grams for $175, or about $5.56 per gram.
Which size is the best value?
| You buy | Everyday gift | Total flower | Effective price per gram |
|---|---|---|---|
| 3.5g ($25) | None | 3.5g | about $7.14 |
| 7g ($50) | None | 7g | about $7.14 |
| 14g ($100) | 2g free | 16g | $6.25 |
| 28g ($175) | 3.5g free | 31.5g | about $5.56 |
The gift counts total flower in your cart, so you can mix strains. Two different 7g bags count as 14 grams and earn the 2g gift just like a single half ounce.
How free gifts work with daily deals
On top of the everyday gifts, each day has its own special, shown in the gold ticker at the top of the site. Each order gets one gift: whichever is bigger, the everyday gift or the day’s special. For example, five different eighths on a Tuesday earn the 3.5g midweek special, which beats the 2g everyday gift, so you get the 3.5g.
You don’t have to work this out yourself. Before checkout, a gift screen shows exactly which gift your cart has earned, and tells you if a little more flower would unlock a bigger one.
How to pick your size
- New strain? Start with an eighth.
- Know your favorite? A quarter saves you a reorder.
- Ordering for the week, or splitting with someone? A half or an ounce earns a free gift and the best price per gram.
- Want variety and value? Mix strains to reach 14g or 28g total.
Keep bigger amounts fresh in an airtight jar, away from heat and light. Our guide on why some strains lose potency faster covers storage in more detail.
