Subway, translated
Subway’s menu language is largely its own, and some of it is decades old. None of it is complicated once somebody tells you.
Sizes
A six-inch is half a loaf. A footlong is the whole thing: twelve inches, one piece. The published nutrition for a footlong is usually slightly under twice the six-inch rather than exactly double, which is why this site never doubles one to produce the other.
Some countries also list a mini size, and some list a wrap as a size rather than a separate item. Which sizes exist is a per-country decision and the figures differ, which is why each country has its own pages here.
The four formats
The same fillings are sold four ways: a sub (in bread), a wrap (in a tortilla), a salad (no bread, in a bowl) and a protein bowl (a larger bowl, more protein, no bread). These are genuinely different products nutritionally, because the bread is a large share of a sub’s calories and all of its gluten, so they are published separately and kept separate here.
Names that are not descriptions
B.M.T. is now simply the name of a particular cold-cut sub. It does not describe the bread, the size or how it is made.
Several menu names include a cheese or a sauce in the name, such as "Chicken & Bacon Ranch" or "Sweet Onion Chicken Teriyaki". Where the name states a component, we can be confident it is on the sandwich, and that is one of the few composition facts Subway effectively does publish.
"Fresh Fit" and similar labels
Marketing groupings for items under a calorie threshold, which have come and gone over the years and differ by country. They are a shortcut rather than a definition, and the per-item figures are the thing to read.
For the figures themselves, see the Canada menu or the country-specific first-timer guide.
