Quick answer: To roll a king size joint that burns evenly, use about 1 to 1.5 grams of medium-ground flower with the stems removed, a crutch that’s a little wider than usual, and an even line of flower along the whole paper. Shape it before you tuck, pack it down from the tip after sealing, then light it slowly while rotating so the whole tip catches at once. Most uneven burns come from loose spots, not bad luck.
King size papers are great for sharing or for a long, slow session, but they’re less forgiving than smaller papers. At about 110 mm long, a king size paper gives every little mistake more room to grow: a slightly loose section turns into a run, and a clump of dense flower turns into a hot spot. The fix isn’t a special trick. It’s doing the basics a bit more carefully along the full length. If you’re brand new to rolling, start with our guide to rolling joints the right way, then come back here to size up.
King Size vs 1¼: What’s the Difference?
| Paper | Approx. length | Typical fill | Best for |
|---|---|---|---|
| 1¼ | ~78 mm | ~0.5–0.75 g | Solo sessions, learning to roll |
| King size slim | ~110 mm | ~1–1.5 g | Sharing, longer sessions |
Exact sizes vary slightly by brand. “Slim” papers are narrower and easier to roll tight, which is why most people roll king size slims rather than full-width king size papers. For more on how joint sizes compare, see our guide to pre-roll sizes explained.
What You Need
- King size slim papers. Thin rice or unbleached papers burn slow and clean; thicker hemp papers are easier to grip while you learn. Browse rolling papers and trays.
- Tips or crutch card. A crutch keeps the mouth end open and gives the joint its shape.
- A grinder. A multi-chamber grinder gives the most even texture.
- About 1 to 1.5 grams of flower. Whole buds give you control over the grind; see whole flower vs milled flower.
- A tray and a poker. A pen, chopstick or poker tool for packing, and a tray to catch spills.
How to Roll a King Size Joint, Step by Step
1. Prep your flower
Pull out any stems first; they poke holes in the paper and create air channels that turn into runs. Your flower should be dry enough to break apart but still a little springy. Bone-dry flower burns fast and harsh, while damp flower keeps going out. Many people store flower in a sealed jar with a humidity pack to keep it in that middle zone.
2. Grind to a medium, even texture
Aim for a fluffy, consistent grind, finer than chunks but coarser than dust. Powder-fine flower packs too tight and burns hot; big chunks leave gaps. Consistency matters more than the exact size, because on a long joint any uneven patch has room to spread.
3. Make a slightly wider crutch
Fold the end of your tip card into a small “W” or accordion, then roll the rest around it. For king size, roll it a little thicker than you would for a 1¼, around pencil width or slightly more. A wider crutch supports the extra length and stops the mouth end from collapsing.
4. Crease the paper and load it evenly
Hold the paper with the glue strip at the top, facing you, and fold a light crease down the middle. Set the crutch at one end, then spread the flower in an even line across the full length. For a straight joint, keep the line level; for a cone, add a little more toward the far end. Check for thin spots now, because they’re hard to fix later.
5. Shape the whole length before you tuck
Pinch the paper and roll it back and forth between your thumbs and fingers to pack the flower into a firm cylinder. On a king size paper, don’t try to do it all in one motion. Work section by section, starting where the flower feels loosest, until the whole column feels even when you squeeze it gently along the length.
6. Tuck, roll and seal
Tuck the edge without glue under the flower, starting at the crutch end where the shape is easiest to hold, and work toward the tip. Roll up until only the glue strip shows, lick it lightly (too much moisture can make the paper burn unevenly), and press it closed along the whole seam. If you want less paper in the burn, try our backrolling technique.
7. Pack it down from the tip
Long joints settle after sealing, which leaves air pockets. Tap the crutch end on the table, then use your poker to gently pack the flower from the open end. Top it up with a pinch more if it’s sunk, pack again, and twist the tip closed. The joint should feel firm all the way along, with no soft spots.
8. Toast and light it evenly
Hold the flame just below the twisted tip and rotate the joint slowly so the whole edge chars evenly before you draw. Then light it while rotating and take a few gentle pulls. Lighting only one side is the most common reason a well-rolled joint starts to run. A hemp wick or soft-flame lighter makes this easier than a torch.
Troubleshooting: Why Your King Size Joint Isn’t Burning Evenly
| Problem | Likely cause | Quick fix |
|---|---|---|
| Canoeing (one side burns ahead) | Loose section, uneven fill or one-sided lighting | Lightly dab the fast side with a wet fingertip and turn the slow side up |
| Tunnelling (centre burns, paper doesn’t) | Packed too tight in the middle or flower too moist | Touch the flame to the unburnt paper edge; pack a bit looser next time |
| Tight draw | Over-packed or powder-fine grind | Gently twist it between your fingers or open a channel with a poker from the tip |
| Keeps going out | Damp flower or long pauses between pulls | Re-light while rotating; let flower dry out slightly next time |
| Harsh, hot smoke | Grind too fine, pulling too hard | Take slower, gentler pulls; grind coarser |
| Falls apart or runs at the seam | Under-filled or seal not pressed down | Use a bit more flower and press the whole glue line |
Tips to Keep It Burning Evenly While You Smoke
- Take slow, steady pulls rather than hard drags, which overheat one side.
- Rotate the joint a little between pulls, especially when passing it.
- Hold it tip-up when it’s resting, so the slow side catches up.
- Keep it out of wind, which fans one side of the cherry.
- Tap off ash gently; don’t flick hard, or you’ll loosen the packing.
Don’t Feel Like Rolling?
Pre-rolled cones take most of the work out: fill, pack and twist. Or skip it entirely with ready-made pre-rolls, and check out how to smoke a pre-roll for tips on lighting them evenly too.

Frequently Asked Questions
How much weed goes in a king size joint?
About 1 to 1.5 grams for a king size slim paper. Under-filling is a common cause of canoeing, because there isn’t enough flower to hold the shape along the full length.
What’s the difference between king size and 1¼ papers?
King size papers are about 110 mm long and hold roughly twice as much flower as 1¼ papers, which are about 78 mm. They’re better for sharing but less forgiving to roll.
Why does my joint canoe?
Canoeing happens when one side burns faster than the other, usually because of a loose section, uneven fill or lighting only one side. Pack the whole length after sealing and rotate the joint while you light it.
Do you need a tip in a king size joint?
It’s strongly recommended. A crutch keeps the mouth end open, stops flower getting in your mouth, and gives a long joint the structure it needs to keep its shape.
Should a joint be rolled tight or loose?
Firm but not hard. It should hold its shape when you squeeze it gently, but still draw easily. Too tight makes it hard to pull; too loose makes it run.
