Quarter of Weed: How Many Grams You’re Actually Getting
If you’ve searched for how many grams are in a quarter of weed, you’re likely staring at a menu full of unfamiliar terms and want a straight answer. Cannabis measurements follow an imperial system built on ounces, not the neat metric numbers most of us use daily. That mismatch trips up plenty of newcomers who expect round figures like 25g or 50g. Instead, quantities like eighths, quarters, and halves dominate every price list you’ll come across.
A quarter of weed works out to 7 grams, one quarter of a 28-gram ounce. This guide breaks down exactly how that figure is calculated, how it compares against eighths, halves, and full ounces, and what it should cost you. We’ll also look at how long a quarter typically lasts and how to store one properly. Throughout, we’ll point out where BudBuddies makes buying and measuring cannabis simpler, with verified weights and lab-tested quality on every order. First, here’s the number everyone actually wants.
Key Takeaways

How Many Grams Are In A Quarter Of Weed?
A quarter of weed refers to a quarter of a standard ounce, which comes to 7 grams once you divide 28 by 4. This is the direct answer to how many grams are in a quarter of weed, and it holds true across the UK cannabis market. The figure comes from cannabis culture’s long-standing use of the ounce (28.35g, usually rounded to 28g) as its base unit, rather than a clean metric measurement. Two eighths, at 3.5 grams each, also add up to exactly 7 grams, which is why a quarter is sometimes described simply as “two eighths.”
In practice, quarters aren’t always weighed to the exact decimal point. Some vendors round slightly, so you might see a quarter sold anywhere between 6.5g and 7.1g depending on their scales and rounding habits. That small variation rarely matters for everyday use, but it’s worth knowing if you’re comparing suppliers closely. Checking the labelled weight, rather than assuming, is the safest habit to build.
The Complete Cannabis Weight Breakdown
For a full visual guide to cannabis quantities, the complete cannabis weight breakdown runs from a single gram up to a full ounce, with each step simply doubling the one before it. Once you know that a full ounce equals 28 grams, every smaller quantity becomes easy division rather than guesswork. This ladder also makes it simple to compare prices across formats, since every weight is mathematically linked to the next one up. BudBuddies sells each of these exact formats, 3.5g, 7g, 14g, and 28g, as clearly labelled options, so you always know precisely what’s landing at your door.
A gram (1g) is the smallest standard unit, usually enough for one or two joints depending on how tightly you roll.
An eighth (3.5g) is one-eighth of an ounce, and it’s the classic starting size for casual or occasional smokers.
A quarter (7g) is one-quarter of an ounce, exactly double an eighth, and suits people who smoke fairly regularly.
A half (14g) doubles a quarter again, working well for heavier consumption or splitting between a couple of friends.
An ounce (28g) is the full unit and typically offers the strongest overall value per gram of the lot.
Why An Ounce Rounds To 28 Grams, Not 28.35
An ounce is technically 28.35 grams, so where did the extra 0.35 go? Nowhere really, it’s simply rounded away for convenience. Using a flat 28 grams makes dividing into halves, quarters, and eighths clean and simple, rather than producing awkward decimals like 3.54375g for an eighth. This rounding is standard practice across the whole cannabis trade, a convention confirmed in most weed weights and prices guides, not a shortfall in what you actually receive.
How Much Does A Quarter Of Weed Cost?
How much a quarter of weed costs depends on quality, strain, and where you buy it, but the smartest way to judge any price is the price-per-gram formula, total price divided by total weight, a method laid out in most cannabis weed weights and measurements guides. A £45 quarter, for example, works out to roughly £6.40 per gram, and that figure is what you should compare against other sizes and sellers rather than looking at the sticker price alone. Buying a single 7g quarter as one purchase is usually cheaper per gram than buying it as two separate 3.5g eighths, since sellers typically reward larger single orders with a lower rate.
Bulk formats push this further still. BudBuddies’ 24g Popcorn Nugs bags, for instance, bring the cost down to around £3.30 per gram, while Shake and Trim, crystal-rich trim ideal for pre-rolls or homemade edibles, often sits under £3 per gram. Both deliver the same genetics and cannabinoid content as premium Top Shelf Colas, just in smaller or less photogenic pieces, which is exactly where the savings come from rather than any drop in quality. Quality tier matters too, since budget or mid-shelf flower will always cost less per gram than top-shelf buds, so decide whether you’re paying for potency and bag appeal or simply want dependable everyday value.
Why Bulk Buying Saves You Money
Buying bigger amounts almost always lowers your cost per gram. A full 28g ounce priced around £200 works out to just over £7 per gram, noticeably less than buying the equivalent in four separate quarters. On top of that, a 10% discount for crypto payments, first-time buyer vouchers, and a BudPoints loyalty scheme all chip away further at your per-gram cost over time.
How Long Does A Quarter Last, And What Should You Buy?
How long a quarter lasts depends entirely on how often you smoke and how you consume it. Occasional consumers, using cannabis a few times a week, might stretch 7 grams over several weeks or even a month. Regular consumers often work through the same amount in one to two weeks, while heavy or daily users can finish a quarter within a week. The method matters too, since vaping tends to use less flower per session than smoking joints, so a vape user’s quarter often lasts longer than a joint smoker’s.
If you’re newer to cannabis, 3.5g tester bags are a sensible starting point before committing to a full quarter. Regular consumers who already know their habits tend to find better value in the 14g or 28g bundles instead. Matching the format to your actual consumption pattern avoids both running out too soon and letting flower sit around losing freshness.
Getting The Most From Your Quarter
Getting the most from your quarter starts with understanding that its appearance can be misleading. Dense, compact strains pack 7 grams into a tighter, smaller-looking cluster, while airier, fluffier strains take up noticeably more visual space at the exact same weight. This means judging quantity by eye alone is unreliable, and it’s one reason experienced consumers keep a small set of digital scales handy. Weight, not volume, is what you’re actually paying for.
Proper storage keeps a bulk purchase like a quarter fresh for weeks or months rather than days. An airtight glass jar kept somewhere cool and dark protects the cannabinoids and terpenes from light, heat, and air exposure, all of which degrade quality over time. Every product also ships with a lab-tested Certificate of Analysis, so you can verify potency and purity alongside the weight printed on the label.
Tip: Buy a cheap set of digital scales if you smoke regularly. It takes the guesswork out of judging quantity and lets you confirm your order matches the label every time.
The Takeaway
A quarter of weed comes down to one simple figure, 7 grams, a quarter of a 28-gram ounce and double the size of an eighth. It’s the go-to middle-ground purchase for regular consumers who want more than a taster but aren’t ready for a half-ounce or full ounce commitment. Whatever your habits, the price-per-gram formula remains the clearest way to compare deals and avoid overpaying for convenience. Now you know exactly how many grams are in a quarter of weed and how to judge whether a price is genuinely fair.
Bulk formats, loyalty discounts, and honest labelling all add up to better value over time, provided the quality and weight are genuinely as advertised. BudBuddies’ range of lab-tested flower, from 3.5g testers through to full 28g ounces, makes it straightforward to find the right quarter, half, or ounce for your needs, with verified weights and discreet delivery every time.
Frequently Asked Questions
Still have questions about quarters, weights, or pricing? Here are quick, straight answers to the things people ask us most often about buying cannabis by the gram, eighth, quarter, or ounce, whether you’re new to it or just want to double check the numbers.
Is A Quarter Always Exactly 7 Grams?
Seven grams is the standard figure for a quarter, though slight rounding means some vendors sell anywhere between 6.5g and 7.1g. Every product is weighed and labelled precisely, so what’s stated on the pack is exactly what you receive.
How Many Joints Can You Roll From A Quarter?
A standard joint typically uses around 0.3g to 0.5g of flower, so a 7g quarter yields roughly 14 to 23 joints. The exact number depends on how tightly you roll and how much flower you prefer per joint.
Does A Quarter Look Different Depending On The Strain?
Yes. Dense, compact strains pack 7 grams into a smaller-looking cluster, while fluffier, airier strains take up noticeably more space at the same weight. Visual size is never a reliable way to judge how much cannabis you actually have.
Is It Cheaper To Buy A Quarter Or Two Eighths?
Buying a single 7g quarter usually works out cheaper per gram than buying two separate 3.5g eighths, since sellers reward larger single purchases with better pricing. The bulk formats on offer are built around this same logic throughout the range.
Can You Compare A Quarter Of Flower To Edibles Or Vapes?
Not directly. Flower is measured by weight in grams, while edibles and vapes are dosed in milligrams of cannabinoids or measured by millilitres of liquid. Clearly labelled edibles and vapes take the maths out of it entirely.
What’s The Best Way To Store A Quarter To Keep It Fresh?
Keep it in an airtight glass jar, somewhere cool, dark, and away from humidity. This protects the cannabinoids and terpenes that give cannabis its potency and flavour, keeping a bulk purchase fresh for weeks or even months.
