King Size vs King Size Slim vs Super King Size: rolling paper dimensions

Rolling paper formats have names, not standards. King Size, 1¼, Slim and Super King are conventions that the category has settled on over a century, and each mill and each brand cuts to its own figures within them. That is why two packs on the same shelf, both marked King Size, can differ by a couple of millimetres in either direction. This note sets out the common formats in millimetres, explains what length and width actually change in the hand, and defines what Super King Size means for a Skins booklet.

The common formats

The table below gives the ranges you will find across the market. They are ranges rather than fixed numbers because there is no governing body for rolling paper dimensions; the figures are what the category has converged on, and any single brand's leaf will sit somewhere inside them.

Two cautions. First, the sources that publish sizing charts, including the ones listed at the end of this note, disagree with each other by a millimetre or two on almost every row, because they measured different packs. Second, brands sometimes use the same name for slightly different cuts across their own ranges. Treat every number here as a working range and read the pack or the technical sheet for the exact leaf.

What length does

Length runs along the gum strip. A longer leaf gives more length to the finished roll and, at the same fill, a slower, longer burn front, because there is simply more paper and more contents to travel through. The burn note explains why the burn front's speed is set by the paper's weight and watermark rather than by its length; length only changes how long the front has to travel.

Length also changes handling. A 108 mm leaf needs both hands working along its full width, and an uneven fill shows more clearly on a long leaf than on a short one. The single wide format is quick precisely because there is little leaf to manage.

What width does

Width runs across the leaf, perpendicular to the strip, and it is the dimension that decides the diameter of the roll and the amount of overlap at the seal. This is the real difference between King Size and King Size Slim.

Slim is not a smaller paper. It is the same length with less width, which means less overlap and a thinner roll.

On a standard king width of around 55 mm there is enough paper to wrap the contents and leave a generous margin under the gum strip. That margin is forgiving: the tuck can be a little loose, the strip lands on plenty of paper, and the finished roll has a double layer over much of its circumference. On a slim width of around 43 mm the margin is smaller, the tuck has to be cleaner, and the roll ends up with a single layer over most of its surface. The result is a thinner, more elegant roll with less paper in the burn, which is why experienced rollers tend to prefer slim and why the technique note spends time on the tuck.

Width interacts with paper weight. A wide leaf on a heavy stock gives a lot of paper in the roll; a slim leaf on an ultra-thin stock gives very little. The GSM note covers the weight side of that equation. Skins pairs its king formats with two basis weights, medium weight and lightweight, so the amount of paper in the roll is set by weight as well as by cut.

What Super King Size means

Super King Size is the loosest term in the table. It has no industry definition beyond "longer than King Size" and brands use it for anything from a few millimetres of extra length to a substantially longer leaf. When you see it on a pack, the only safe reading is that the leaf is longer than that brand's own King Size.

For Skins, Super King Size is a defined product rather than a marketing word. The range carries two papers in medium weight: King Size and Super King Size. They are the same stock, the same natural gum strip at the same coat weight, and the same cross-weave watermark. Only the length changes. The burn profile is identical because the paper is identical; the extended leaf simply gives the burn front further to go. The Super King Size booklet is the one on the face of the case in the product renders, and it is the booklet most stockists start with when they want a single reference format.

The exact leaf dimensions for both are printed on the technical sheet that goes to stockists, alongside the specification described on the paper page. They are not reproduced here because a sizing note that quotes millimetres for its own products invites the same 2 mm arguments it has just warned about. The sheet is the authority.

How to choose a format

There is no correct size, only a correct size for a given roller and a given intent. A few working rules:

• Structure and speed: King Size in medium weight. Enough width for a forgiving tuck, enough body to roll quickly and hold shape. This is the reference roll and the one the Skins specification was written for.
• A thinner roll with less paper: King Size Slim, or a king width on a lightweight stock. Both reduce paper in the burn; slim does it through width, lightweight does it through basis weight.
• Length: Super King Size when the extended leaf is wanted. Same paper, same burn, more of it.
• Short and quick: single wide or 1¼. Skins does not make these formats; the range is built on king and super king.

Whatever the format, the things that decide how a paper behaves once lit are its weight, its fibre and its watermark, not its name on the pack. Those are covered in the note on how ultra-thin paper is made, and they are the things the Skins lab tests batch by batch.

Reading a pack

A quick method for comparing two packs when the numbers are not printed: lay a leaf from each on a flat surface, strip edge to strip edge, and align one corner. Length differences of 2 mm are visible immediately; width differences show at the far edge. If a brand's King Size and another brand's King Size Slim differ only at the far edge, you are looking at the width story in this note. If they differ along the strip, one of them is closer to a super king cut than its name suggests.

Sizes are a language the category shares imperfectly. The formats above are the vocabulary; the technical sheet is the dictionary for any specific paper.
