Pre-rolled cones are sized by paper length in millimeters, and that length predicts fill weight: 70mm minis hold about 0.3g, 78mm to 84mm 1¼ cones hold 0.5g to 0.75g, 98mm cones hold about 1g, 109mm to 110mm king size cones hold 1g to 1.5g, 140mm cones hold 2g to 2.5g, and 180mm party cones hold 3g to 4g. The number on the package is the paper length, not the tip size. Actual capacity shifts with grind, moisture, and how firmly you pack.
What sizes do pre-rolled cones come in?
Six lengths cover almost every cone sold in US dispensaries. Each figure below assumes a medium grind and a light tamp.
- 70mm mini: 0.25g to 0.4g. Sold as single-serve or dog walker cones.
- 78mm to 84mm (1¼): 0.5g to 0.75g. The most common size on dispensary shelves.
- 98mm (lean or king slim): about 1g. A slim profile with a longer burn.
- 109mm to 110mm (king size): 1g to 1.5g. The standard sharing cone.
- 140mm (double king): 2g to 2.5g. Built for slow, extended sessions.
- 180mm and up (party): 3g to 4g. Often used for infused flower or events.
How much flower actually fits in each cone?
Length does not measure how much cannabis a cone accepts. Fill weight depends on grind coarseness, moisture, and packing pressure. A fine, dry grind can add 20 to 30 percent more weight to the same paper, while a coarse grind leaves air gaps that cut capacity.
What is the difference between a 1¼ and a king size cone?
A 1¼ cone is roughly 78mm to 84mm long and holds 0.5g to 0.75g. A king size cone is about 109mm to 110mm and holds 1g to 1.5g. King size cones also run slimmer relative to their length, which slows the burn rate.
Does cone tip width matter?
Yes. Most standard cones ship with a 26mm tip, and wide formats use 32mm or larger openings. A wider tip draws more air per puff and cools the smoke, while a narrow tip concentrates flavor and slows the draw. Match wider tips to resinous flower and narrow tips to a smoother, longer session.
Which cone size should you choose?
For one person
A 70mm or 84mm cone keeps a solo session from burning more flower than you plan to use.
For two to four people
An 84mm to 110mm cone is the practical middle ground. One king size cone serves two to three people.
For groups and events
A 140mm or 180mm cone reduces relighting and passing delays. Pack it in layers so the draw stays even from start to finish.
How do you fill a pre-rolled cone?
- Grind flower to a medium consistency and remove stems.
- Scoop or pour flower into the cone, tapping the tip against a surface as you go.
- Pack gently with a poker, leaving a small gap at the top.
- Twist the open end closed, then light the edge evenly.
Overpacking restricts airflow and creates a hard draw. If the cone feels dense, roll it between your fingers to loosen the flower before lighting.
Frequently asked questions
Is a 1¼ cone the same as a king size?
No. A 1¼ cone is shorter and holds about half as much flower as a king size cone.
Do longer cones burn hotter?
Not by default. Burn temperature tracks draw speed and airflow more than paper length. Longer, slimmer cones often burn cooler because air moves through them at a lower rate.
Can you reuse a pre-rolled cone?
No. The paper and tip are made for one session, and a burned cone cannot be refilled cleanly.
Buying cones at a licensed dispensary
Cone sizes, paper materials, and tip widths vary by brand, so compare the millimeter length printed on the package rather than the marketing name. On a menu, the millimeter number is the fastest way to predict fill weight. Customers must be 21 or older with valid ID.
