Newport comes in two formats that matter here: the standard king-size box and the 100 box. Same brand, same menthol, same 20 per pack. The extra 15 millimetres change more than the measurement suggests.
The physical difference
King size is 85mm. The 100 is 100mm. Both are box format, both are 20 per pack, both are cartons of ten packs and 200 cigarettes.
The 100 uses a longer filter and a slightly longer rod. Tobacco weight per cigarette is close to the king, because the blend is adjusted to keep delivery in a similar band.
What the extra length does
Three things, all small but cumulative.
Cooler smoke. A longer path means more cooling before the smoke reaches you. On a menthol cigarette this compounds with the menthol effect, and it is the main reason people prefer the 100.
More puffs. A longer rod gives a handful more draws. The session stretches.
Lighter-feeling draw. The same blend drawn through a longer rod reads slightly softer, which some smokers find less satisfying and others find exactly right.
Price, and an oddity
At the moment the 100 is the cheaper carton from us: $79.90 against $85.00 for the king. That is not a format rule — the two normally sit close together — it reflects current stock and sourcing on each line.
If you are format-agnostic, that $5.10 gap is worth taking. If you specifically want the king, the difference is small enough not to matter.
Which to choose
If you find Newport’s king version a touch aggressive, the 100 is the standard move. If you want the full hit and the shortest session, the king is the original and the reference.
For a first purchase, the 100 is arguably the safer choice — the cooler smoke is more forgiving, and it is currently cheaper. If you already know you like the king, stay there.
What does not change
The menthol load, the tobacco blend family, the sweetness, the packaging format. The 100 is not a lighter cigarette; it is the same cigarette in a longer format. Anyone expecting a milder experience should look at a genuinely lighter product rather than the 100.
If you want lighter, see what mild actually means.
