The classic guide size is 7 × 47: 177.8 mm by 18.653125 mm. Habanos lists the Julieta No. 2 factory format at 178 mm by 47. Use 178 mm for that factory record, without replacing it with a shorter rounded estimate.
A 180 mm exterior is not a 180 mm interior
Walls, cap overlap, inserts and tray ends occupy space. No fixed subtraction reliably turns exterior length into usable length. Our finder only compares a Churchill with an explicitly listed usable length; a 180 mm leather case with no interior figure remains unconfirmed.
A narrow margin needs a clear label
Against a listed 180 mm maximum, a 178 mm Churchill leaves 2 mm length clearance. Against a listed 190 mm slot it leaves 12 mm. Both calculations are transparent; the first receives a near-limit flag. Neither replaces a physical fit check or confirms how the lid closes.
