    Is a medium enough for two adults for lunch? TIA 🙂

    • Blessed

      The picture is about right I would say it’s about 4 inches. I literally just ate a large by myself but I’m a big eater 😂.

      • JenniferS

        Thank you for your information Blessed 🙂

      A medium is 8 inches long and contains 4 oz. of meat, except the hero which has 6 oz. of meat. I see a response that says it’s four inches, but it’s not. That is a small. Small is 3.5 to 4 inches. Medium is 8 and Large is 12. I’m a Firehouse District Manager.

        Thanks so much, Trineke!

      I have a large 14-year old (6’2″) who eats a large. My husband eats a medium, but I eat a small. Hope this helps a little, JenniferS!

      No way.

    A medium is not that big for two people in my opinion. I guess if you took it home and hade something to go with it then it would.

    • CW

      Agreed. We can split a large but not a medium as two adults

    • Anne

      We just recently ate at Firehouse… I agree – I don’t think splitting a medium would be enough food for 2 adults unless you were light eaters. My husband and I get a large sub to share and it’s the perfect amount of food for us.

    Firehouse Sub Day is my version of The Office’s Pretzel Day. I love this day every year!

    Seems easier to just buy a sub and save on the water cost.

    • Donna

      I think the whole point of this is to donate to a good cause, not to get a good deal

  5. Amy

    How is a 8 inch sub not enough for two people for lunch? I’m sure it’s about 800 calories for the whole thing, so 400 is reasonable for lunch.

      Calorie intake is different for everyone.
