King Size Papers
Extra-long rolling papers, typically 100-110mm, designed for larger joints that burn longer and hold more cannabis.
King size papers are just bigger rolling papers. Nothing magical, no special chemistry — they're longer than standard 1¼ papers so you can pack more flower and roll a joint that lasts a group session. The main real distinction worth knowing is 'King Size' (wider) vs 'King Size Slim' (same length, narrower). Everything else — hemp vs rice vs flax, watermarks, 'ultra-thin' — is preference and marketing. Pick a paper that stays lit and doesn't taste like glue.
Definition
King size papers are rolling papers roughly 100-110 mm long and 55-60 mm wide, sized to hold appreciably more cannabis than standard 1¼ or single-wide papers [1][2]. The two common variants are King Size (full width) and King Size Slim (same length, narrower — around 44 mm wide), which is the most popular joint-paper size sold globally [1].
They are sold by every major paper brand — RAW, OCB, Elements, Zig-Zag, Rizla, Smoking, Randy's — in materials ranging from unbleached hemp to translucent rice to flax [1][2].
What they do
- Hold more flower. A king size slim comfortably rolls a joint containing 0.75-1.5 g; a full-width king size can hold 1.5-2+ g. Compare to a 1¼ paper, which is typically loaded with 0.3-0.5 g.
- Burn longer. More paper and more flower means a longer session — the main reason king size is the default for group smoking.
- Give more rolling surface. Easier to roll cones, tulips, or specialty shapes.
Paper material affects burn rate and ash color, but claims about 'cleaner' smoke are largely uncontrolled. Combustion of any plant matter produces tar, carbon monoxide, and known carcinogens regardless of paper type [3][4]. Strong evidence
What they don't do
- They don't make cannabis 'stronger.' A bigger joint just contains more cannabis; potency per hit depends on the flower, not the paper.
- 'Ultra-thin' or 'organic' papers don't meaningfully reduce health harm. Smoke from cannabis combustion contains many of the same harmful compounds as tobacco smoke [3][4]. Paper choice is a rounding error compared to the act of combustion itself.
- They aren't a standardized size. 'King size' varies a few millimeters between brands. RAW King Size Slim is 110 × 44 mm; OCB and Zig-Zag are similar but not identical [1][2].
Size context
Common rolling paper sizes, shortest to longest:
| Name | Length | Width | |---|---|---| | Single Wide | 68-70 mm | 34-36 mm | | 1¼ | 76-78 mm | 45-48 mm | | 1½ | 76-78 mm | 60-62 mm | | King Size Slim | 100-110 mm | 44 mm | | King Size | 100-110 mm | 55-60 mm |
King Size Slim is the de facto global standard for pre-rolls and adult-use joints; 1¼ dominates the U.S. personal-roll market [1].
